However, Moose's reluctance to come out prevented this relationship from ever truly developing. Although they did date for a time, in secret in season 3

He, along with Midge, were attacked by the Black Hood though only Moose was harmed as he shielded Midge from the gun fire. With the help of Kevin, he was rushed to a hospital where he later made a full recovery.

Over the summer, Moose rekindled his relationship with Kevin, though they kept it a secret as he had yet to come out. After being strong-armed by Cheryl, Moose came out to his father about his sexual attraction to men. And though his father initially seemed to accept this, he later plotted with the other RROTC cadets to scare Moose straight. This resulted in Moose leaving Riverdale to stay with his aunt in Glendale. He has as since enrolled in Stonewall Prep.

Early Life

It is currently unknown whether or not Moose grew up in Riverdale. There's also nothing known of his home life, such as his family, other than his father is Marcus Mason. However, his closest friend appears to be Reggie Mantle, as they are almost always together.

Having learned that Andrews Construction, the company that is owned by Archie's father, was facing great misfortune, Moose, Archie, Jughead and Keller volunteered to assist him in the SoDale project and keep him on schedule until he could find a real crew. Unlike everyone else, Moose rather enjoyed the hard labor, he preferred working on the construction site instead of the weight room. The day had come to an end as the boys returned to the trailer, but Moose accidentally left his phone back on the project site, as he returned to retrieve it, he stumbled upon two thugs damaging Andrews construction equipment. They then turned their attention to Moose, knocking him to the ground and beating him bloody, before warning him that they'd return if construction for the SoDale project didn't come to an end.

While the original plan was to find the thugs responsible and call Sheriff Keller, Archie took it upon himself to confront the Serpent, which didn't end well as they were greatly outmanned. Luckily, the fight was brought to an end by FP Jones, the leader of the Serpents and Jughead's father. He removed the boys from the bar, and set them home before they could cause any further trouble. [6]

Season 1 Episode 10 The Lost Weekend Moose and Tina

Moose with a keg

A large group of students. Moose included, were led by Cheryl and Chuck as they crashed Jughead's 16th Birthday Party at Archie's house. With a keg over his shoulder, Moose wondered where Archie wanted them, which he replied one in the kitchen and one in the backyard. Then he and Cheryl took the dance floor, where they danced and kissed. He was also there to bear witness to Archie's altercation with Valerie, which he, Chuck and Cheryl had a good laugh about. Unfortunately, the party abruptly came to an end as a fight between Jughead and Chuck resulted in FP sending everyone home.[7]

Though Jason Blossom's jersey had been retired, the Riverdale Bulldogs were still set to play the Baxter High Ravens, Moose included.

Deadly Days at Lovers' Lane


Moose and Midge taking drugs in the woods

After learning that Riverdale High's former music teacher, Ms. Grundy, was murdered in her Greendale home the previous night, Moose and Midge attended Retro Night at Pop's Chock'lit Shoppe, where they scored some Jingle Jangle from Reggie in the diner's parking lot. Unbeknownst to them, they were being photographed by Alice Cooper. Later that night, Moose and Midge drove out into the woods, where after taking the Jingle Jangle, they began kissing in the car. However, before they could go any further, a man wearing a black hood appeared from the darkness, shining a flashlight into the car, and firing several shots.[10]


Moose recovering in the hospital

Moose was joined at Riverdale General Hospital by Archie and Reggie after being shot multiple times by the Black Hood. Fortunately, he would survive the attack and Midge was left unharmed due to his heroic actions in which he used his own body to shield her from the gunfire. Archie assured him that he saved her life. After stealing his dessert, Reggie asked Moose if his nurse was attractive. If so, he ran the risk of getting a boner during a sponge bath. Moose laughed in response. Archie then questioned him about the shooter's appearance, mostly regarding the black hood he wore to conceal his identity and the color of his eyes, the answer to which Moose did not provide, as he was cut off by Midge, who entered the room, and described the shooter's eyes as being blank, comparable to the eyes of the devil or Michael Myers.


Kevin visiting Moose in the hospital

A couple days later, Moose received a visit from Kevin Keller, who he informed that Midge wanted to thank for saving their lives. He wondered what Kevin was doing in the woods, to begin with, though Kevin turned the question back onto Moose, asking him what he was doing in the woods with Midge, beyond taking Jingle Jangle, which everyone had already been made aware of. Moose claimed that it was Midge's idea. She had a wilder side that she occasionally indulged in. While he had genuine feelings for Midge, he wasn't entirely sure that they were a match. Noticing a trouble looked on Kevin's face, Moose asked him if everything was alright. Kevin replied that he had been making bad decisions lately and lying to his father. He knew it was dangerous, but he couldn't stop himself from sneaking around the woods at night, looking for hook ups. Its as if he didn't even care about his own well being. Moose explained that this was due to the lack of options for guys like them in Riverdale. So, even if something bad could happen, they go for it because what if, for however long, they're no longer alone. As Kevin headed out the door, Moose told him that he could stay or come back at a later time if he wanted to hang out or talk.[11]


Midge and Moose at the secret santa exchange

In the days leading up to Christmas, Moose and Midge entered the student lounge at school to find Archie, Betty, Cheryl, Kevin, Veronica, Jughead and Josie opening presents as part of a Secret Santa gift exchanged. Moose and Midge were welcomed back by hugs from Josie, Reggie, and Kevin.[12]

Moose was approached by Kevin while at his locker to see if he wanted to accompany him to the Bijou to watch the 2018 American romantic comedy-drama film Love, Simon. Unfortunately for Kevin, Moose had already planned to go with Midge though he did invite Kevin to tag along, claiming that Midge knew all about them. Supposedly, she was cool with it, but Kevin passed on the offer nonetheless.


Midge and Moose at Pop's with Kevin

The following night, Moose and Midge stopped by Pop's Chock'lit Shoppe. There, they found Kevin eating alone. So Midge invited him to join her and Moose in their booth. Midge assumed that Kevin would be meeting someone at the Bijou, but unfortunately, he wasn't. Which Midge found to be unacceptable. She offered to help him find a date, suggesting one of the new Southside Serpents that had recently transferred to Riverdale High following the closing of Southside High. She had heard that at least one of them was gay, Fangs Fogarty. However, Kevin explained that he didn't think he could date someone named "Fangs". Moose interjected that Kevin should at least give Fangs a chance since he was attractive though Midge disregarded his comment. She then asked how Kevin and Moose became friends. Though Moose and Kevin came to know one another through pre-planned sexual encounters, Kevin told her that they were lab partners in Biology.[13]

Editor's Note: While actors Cody Kearsley, Casey Cott and Moses Thiessen do appear in the following scene, they do not portray the characters whom they are credited for i.e. Moose Mason, Kevin Keller and Ben Button. Instead, they portray young men who eschew from socializing with women to spend time together.

Kevin and Moose at the river

During movie night at the Sisters of Quiet Mercy, the patients were forced to watch a film about homosexual deviance that outwardly starred Moose and Kevin. These two seemingly all-American boys chose to abstain from going to the diner with their friends to have chocolate phosphates with the girls, and instead headed down to the river, where they undressed and went for a swim without clothes.[14]


Musical rehearsal

Moose ran into the auditorium with Cheryl, Toni, Betty, Veronica, Archie, Josie, Ethel, Kevin and Midge. They got on stage, where they continued to sing and dance before being joined by Fangs, the assistant director. The cast then began introductions, starting with Archie who portrayed "Tommy Ross", the boy next door. Betty played "Sue Snell", the good girl. Veronica portrayed "Chris Hargensen", the mean girl. And Cheryl would be playing the iconic role of "Carrie White". As for who would be portraying, "Margaret White", Carrie's mom, that role went to Alice Cooper, which came as a surprise to almost everyone. Kevin explained that while her casting was untraditional, to him, there's nothing more amateur than age-inappropriate casting. Alice was both looking forward to playing Margaret and spending more time with Betty. Chuck Clayton joined them late after mistaking that rehearsal was in the music room.


Moose and Midge at rehearsal

Cheryl interrupted rehearsal after hearing whisperings that some of them, mainly Ethel and Josie, didn't think she's fit to play the role of Carrie White. So to settle the matter, she began to sing "Carrie" to prove them wrong. Her singing removed all doubt as Moose, Midge, Archie, Veronica, Betty, Ethel, Josie, Alice, Toni, Jughead, Kevin, Fangs, and Chuck gave Cheryl a round of applauded. As Cheryl headed back to her seat, a heavy sand bag fell from above and nearly crushed her.

Toni, Veronica, Ethel, Betty and Chuck rehearsed in the auditorium, where they sang and performed "The World According to Chris". Moose, Midge, Archie, Fangs, Kevin and Jughead are highly impressed with Veronica as they applauded the routine. Betty credited Veronica's performance to her being the literal embodiment of Chris, the character she's portraying. Never had a role been so perfectly type-cast, Betty remarked.


Midge is announced as Cheryl's understudy

Due to some unforeseen circumstances, Kevin informed Moose, Midge, Toni, Archie, Veronica, Jughead, Fangs, Ethel, Alice, Betty, Chuck and Josie that Cheryl will no longer be playing Carrie. When they asked why, Kevin simply replied that Penelope Blossom wasn't much of a stage mom. In the meantime, Cheryl's understudy would assume the role, that being Midge, who Kevin appointed after the sand bag incident.

Opening night, in the dressing room, Moose, Midge, Toni, Archie, Betty, Veronica, Kevin, Alice, Chuck and Ethel sang "A Night We'll Never Forget". Afterward, Moose appeared to be in a bad mood as he passed Jughead in the hallway.

The crowd was packed when the play began, and Alice started to sing "Evening Prayers". When Alice cued Midge, the curtains raised only to reveal that Midge had been murdered by the Black Hood. She had been stabbed with knives and scissors and pinned to the wall. On the wall, written in blood was a message. "I Am Back From The Dead. All Those Who Escaped Me Before Will Die... B.H" When Alice screamed in fear, the crowd realized that this was not part of the play and the auditorium erupted in panic and chaos.[15]

The Loss of a Loved One


Reggie and Moose at Midge's funeral

The town gathers for Midge's funeral to pay respect. Cheryl sings a song in Midge's honor. She and the rest of the River Vixens are dressed in all-black cheerleader uniform. Midge's death has seemingly taken a great toll on Riverdale, Mrs. Klump and Moose especially. Moose stands alongside Reggie, who consoles him as the service commences.

Afterwards, Sheriff Keller begins his investigation into Midge's murder, starting with interrogating everyone involved in the play. Sheriff Keller asks Moose if he remembers the last thing he said to Midge, but Moose claims to have no recollection, stating that his last words to her were probably something casual or stupid.[16]


Moose admits that Midge was cheating on him

If what happened to Midge taught them anything, it's that no one is safe and that the town needs the Dark Circle. So Archie rallies the guys in hope that they will join him. This time around, they'll even have the Sheriff's support. Kevin is there as well, but only to help catch the guy that took his father's job. Moose has a confession to make. The night of the musical, he and Midge got into an argument because she admitted that she was seeing someone else, a Southside Serpent is all he could get out of her. Reggie is outraged. Reggie knew the Serpents would do something the second they stepped foot into the school. When Kevin asks why Moose didn't say anything before, he explains that he didn't want to become a suspect. Archie wants to go to the authorities with this information, but Reggie would rather find out on his own who the Serpent is that was hooking up with Midge.


The Dark Circle interupts the Swords & Serpents meeting

Moose, Kevin, Reggie, Archie and the rest of the Bulldogs interrupt the Serpents' Swords & Serpents meeting. They've come for answers to who was hooking up with Midge. Reggie immediately points his finger at Sweet Pea, who does not take the allegation lightly. He claims that while he didn't know Midge, he completely understands why she wouldn't want flees from the mangy Bulldogs. Reggie is angered by Sweet Pea's insult and pushes him. This nearly leads to a fight. Thankfully, Archie and Jughead are there to keep their respective sides at bay.


Moose, Reggie and Kevin find Fangs

Leaked behind the scenes documentary footage of Fangs in Midge's dressing room on the night of the Musical surfaces. With this, Moose, Kevin, Reggie and the rest of the Dark Circle begin their search for Fangs as they are certain that he is Midge's killer. It doesn't take them long to find him. On one end of the hallway stands the Dark Circle, on the other ends stands Sheriff Minetta and his deputies. Fangs insists that he didn't do anything, but when he tries to run, Sheriff Minetta wrestles him to a wall as he resists arrest. In doing so, a switchblade falls out of Fangs' pocket. Seeing this, Sheriff Minetta slams Fangs onto the ground before cuffing him.

Halfway across town, Reggie leads Moose, Kevin and the Dark Circle as they set a dumpster on fire and slash all the tires just outside the Whyte Wyrm.


Archie tries to disband the Dark Circle, but fails

A meeting of the Dark Circle is called after Archie heard about what they did on the Southside by setting dumpsters on fire and slashing tires. Reggie claims they were celebrating Fangs' arrest. Archie counters that his wrongful arrest isn't something to celebrate. However, Kevin argues that Fangs had a knife on him, making him look very guilty. Archie refuses to argue with them anymore. With that being said, he announces that the Dark Circle is officially disbanded. However, Reggie, Moose and Kevin have no intention on stopping. It's not Archie's decision to make as Hiram is the one paying them. He even suggested that they go out and have a little fun. While Archie may have started the Dark Circle, Hiram stated that it is now Reggie's.

Moose, Kevin, and Reggie later attend the Mayoral debate at Town Hall between Fred Andrews and Hermione Lodge until the Black Hood arrives and begins shooting[17]


Moose helps look for Reggie

Moose, Kevin, Archie, and the Bulldogs meet in an alleyway. None of them seem to know of Reggie's whereabouts. He and Archie got separated when the fight broke out. Archie explains that Reggie had a gun, but Archie tackled him before he could shoot Fangs. When Kevin asks why Reggie would have a gun, Archie suspects that Hiram Lodge put him up to it. Nonetheless, they have to find Reggie as some of the Southside Serpents saw him with a gun. Moose, Kevin, and Archie head to Reggie's house while the rest of the Bulldogs fan out to find him before the Serpents do.


Archie, Moose and Kevin look for Reggie

While Moose, Kevin, and Archie search for Reggie, Archie calls Jughead to inform him that the Serpents are trashing the town. Jughead is well aware. He surmises this is due to Reggie shooting Fangs. However, as Archie explains, Reggie didn't shoot Fangs. So Jughead needs to call off the Serpents. They just came from Reggie's house, but he wasn't there. Moose, Kevin, and Archie are now headed to Riverdale High School as that's where Reggie's mother said he was going. Jughead arranges to meet them.

Moose, Kevin, and Archie enter Riverdale High through a classroom window. Just outside the classroom, the Southsiders demolish the school in retaliation for Fangs' shooting. Archie reminds Moose and Kevin that they're out manned and unarmed. However, Moose and Kevin refuse to hide while the Serpents destroy the school. Archie agrees to join them, but only if they're organized in they're attack.


Moose, Kevin, and Archie prepare to defend the school

Moose, Kevin, and Archie demand that Sweet Pea and the Serpents stop vandalizing the school. As the Serpents approach, Archie swears to him that Reggie didn't shoot Fangs. He says it was Mrs. Klump, but Sweet Pea isn't buying it considering that he saw Reggie with a gun outside the station. However, as Archie points out, Sweet Pea also saw Archie tackle Reggie before he could pull the trigger. Nonetheless, whether it was Reggie or Midge's mom who shot Fangs, a Northsider put him in the hospital, where he is hanging on for dear life. Northsiders took his friend and his land. And they'll take everything if the Souhtsiders give them the chance. So now, Moose, Kevin, and Archie get to watch as the Serpents burn the school to the ground. Sweet Pea then throws a trashcan into the display case, shattering the glass. Armed with nothing more than bats and sticks, Moose, Kevin, and Archie prepare to fight off the Serpents. Fortunately for them, Mr. Weatherbee arrives with backup and a baseball bat of his own to see to the end of the confrontation. Afterward, they meet with Jughead and tell him the Serpents are gone.


Moose, Reggie, Archie and Kevin at Pop's

Moose, Kevin, and Archie convene with Reggie at Pop's. Reggie didn't know where else to go after Hiram hung him out to dry. Just as Archie questions if Hiram put Reggie up to shooting Fangs outside the station, Southsiders supposedly pull up outside of Pop's. Archie calls Jughead to ask where he and the Serpents are at. Jughead informs him that he just brought them back to the Whyte Wyrm and Mrs. Klump's house is secure. Given that the Serpents are at the Wyrm, they begin to wonder who has just pulled up outside. At a closer look, they discover that Malachai and the Ghoulies have returned. Kevin and Moose block off the door as Archie calls the sheriff station. Unfortunately, no one answers. When the Ghoulies bust the front window, Archie goes to the roof and throws Molotov cocktails at the Ghoulies, holding them off long enough for Kevin, Archie and Jughead's dads to force them to retreat.[18]


Kevin and Moose

Moose is in the bathroom crying. He is found by Kevin. Moose wipes away his tears before revealing that all of Midge's belongings are gone. Midge's locker was trashed during the riots. All her books, stuffed animals and the notes that their classmates left her are gone. Kevin hugs Moose, hoping to console him as he reminds Moose that these are all material things and that he'll be alright. Moose then kisses Kevin, who is taken by surprise by this display of affection. Though hesitant, Kevin kisses Moose back and they proceed to make out in the restroom.


The Northside and the Southside untie against Weatherbee

A couple days later, after Archie, Jughead and Cheryl saved the Serpents from a raid at the Whyte Wrym, Moose joins them and the rest of their classmates. The school comes together in a show support of the Southside students who are being wrongly transferred. Moose, Archie, Jughead, Josie, Veronica, Reggie, Cheryl, Toni, Sweet Pea, Kevin and many other students put on Serpent jackets and confront principal Weatherbee. Archie explains that everyone is ready to walk out. Mr. Weatherbee threatens to expel any student that does, though Archie calls his bluff. He knows that Weatherbee is a good man who doesn't discriminate, and if he isn't, Archie tells Weatherbee to expel him as he doesn't wish to be apart of that. With that being said, Weatherbee tells everyone to get to class.

Both the mayoral election and student body election are held in the gymnasium of Riverdale High. Among the voters are Moose, Josie, Pop Tate, Weatherbee, Sweet Pea, Veronica, Reggie and many others.


Reggie, Moose and Kevin celebrate Archie's election

Moose, Kevin, Archie, Jughead, Veronica, Sweet Pea, Toni, Cheryl, and Reggie are in the student lounge when Mr. Weatherbee announces that the student council election votes are in. The new student body president of Riverdale High is Archie Andrews. The entire student body applauds his election. In unrelated news, Weatherbee also announces that for the foreseeable future, all former Southside High students will remain at Riverdale High. The entire student body applauds once more in celebration.


Campaign party at Andrews house

Moose attends the party over at the Andrews house as they wait for the votes to come in for the mayoral election. Moose, Kevin, Archie, Sierra, Veronica, Reggie, and Josie all attend. Unfortunately, Fred loses the mayoral race to Hermione. Not long after this news breaks, Hermione stops by to tell Fred that he ran a great campaign. It was close. It came down to less than 200 votes. As a show of good sportsmanship, Hermione and Fred shake hands.

The following day, Moose and Reggie watch proudly from the stands as Archie prepares to be inaugurated in the school gymnasium. However, the event goes awry when Sheriff Minetta and two deputies enter the gym to arrest Archie for the murder of Shadow Lake resident, Cassidy Bullock.[19]

Season 3


Moose at Archie's trial

Three months have passed since that fateful evening in the school gymnasium where Archie was framed by Hiram Lodge and arrested for the murder of Cassidy Bullock. Archie's trial is now in session. Moose sits alongside Kevin. Archie is being prosecuted by District Attorney, Ms. Wright. She attempts to paint Archie as a bad person in her closing argument as Mary, Archie's counsel, attempts to shed light on all the good deeds Archie has done, such as helping solve the murder of Jason Blossom, providing the Southside Serpents with refuge as they hid from the police, and punching through a layer of ice in order to save Cheryl from drowning. With that in mind, Mary takes the opportunity to remind the jury that there were no witnesses, murder weapon or motive to the killing of Cassidy Bullock. After hearing from both the prosecution and the defense, the jury begins to deliberate.

The Judge calls everyone back in to reveal that the jury is still deliberating, but he's also dismissed them for the evening. They're sequestered and he's instructed them not to read anything about this case, nor to discuss it with anyone. They'll reconvene all Tuesday morning after Labor Day. With that being said, the Judge advises Archie to spend the weekend with his family and loved ones.


Moose nervously agree to a pact with Kevin

The following day, Moose attends Cheryl's End-of-Summer pool party at Thornhill with Kevin. Kevin stops his reading to make a pact with Moose, which requires them to lose their virginity before Halloween. Moose seems uncomfortable and unsure but shakes his head in agreement anyways.

Labor Day weekend is over and Archie's trial is now in session. Moose, as well as the rest of Archie's friends and family are in attendance. However, the jury could not reach a verdict. They're deadlocked. Six-to-six. With that, the jury is dismissed. In lieu of another trial, the State is prepared to offer a deal for a lesser sentence. Instead of prison, time served plus two years in juvenile detention, if Archie will plead guilty to the crime of manslaughter. Archie takes the deal and in arrested.[20]


Moose is kissed by Kevin

Moose is given a surprise kiss from Kevin in the hallway with a kiss, hoping to sneak off to the boiler room with him, but Moose pulls away as his father is right across the hall with Mr. Weatherbee. Moose's father is the new RROTC instructor and he's making Moose sign up. So, if he's going to be around school, Moose and Kevin have to take it easy.

Kevin greets Moose as he enters the diner with his RROTC buddies. Moose cuts Kevin off as he was about to call him handsome in public, leaving Kevin to suspect that Moose is ashamed of him. Moose claims this is not that case and that he'll see Kevin later.

Much to Moose's surprise, Kevin joins the RROTC at the last minute. Major Mason recognizes Kevin as Tom's son, who he ran the RROTC with years ago. Major Mason welcomes Kevin and he takes a seat next to Moose.[21]


Kevin and Moose make out

It was a day like any other as Moose and Kevin sneak away into an empty classroom, where they make out, during which time Moose suggest they take another hit of Fizzle Rocks. However, Kevin would rather continue kissing. While making out, Moose and Kevin hear Cheryl’s scream from the hallway. They exit the classroom to find all the Vixens, with the exception of Cheryl, seizing on the floor. Kevin tends to Veronica and Cheryl tends to Toni, calling out for help. Later that day, Moose, Kevin and the rest of the RROTC come barging into the Pop's giggling hysterically, high off Fizzle Rocks.

While at Pop's, Moose, Kevin, and the other RROTC cadets are appraoched by Cheryl and Veronica. Veronica informs them that their meals are on the house and that she needs them as back up. When Kevin asks what this is about, Cheryl dramatically stomps on the table and tells the cadets that they’re going to war.


Pop Tate, Veronica, Kevin and Moose in Pop's

Moose, Kevin, Cheryl, Veronica, and the other RROTC cadets barge into the mayor's office. They know the endgame and so Veronica attempts to relieve her mother of her mayoral duties. Veronica tells her to step away from the phone before she makes the biggest mistake of her life. Hermione informs Veronica that she can’t depose her as she’s an elected official. Furthermore, Veronica’s too late. The order went out ten minutes ago. She was just about to call and tell Veronica. All their phones receive a message simultaneously as a siren begins to sound throughout town. That night, Moose, Kevin, Veronica, Pop Tate and the cadets stand around the diner in sorrow as the sirens continue to sound off.[22]


Moose enforces the school's new rules

While the quarantine has since been lifted from over Riverdale, five weeks later, the town has yet to regain its pep. As Cheryl and Toni walk through the halls of Riverdale High holding hands, they are instructed to separate by Moose, acting under RROTC command. Kevin informs Cheryl that one of the school’s new rules is to keep physical contact to a minimum. Toni questions this new rule as there hasn’t been any seizures for weeks and everything tested has come back negative. With that being said, Cheryl and Toni completely ignore Kevin and Moose’s order, referring to them as crypto-fascist before proceeding on their way.[23]

Moose enters the diner with his father to find Kevin, Josie, Sierra and Tom together in s booth. Sierra and Tom take the opportunity to invite them to the wedding, though Marcos doesn’t appear to be too enthusiastic, almost brushing off the invite.


Kevin wants Moose to come out to his dad

Moose and Kevin find time to make out in an empty classroom. Kevin stop to ask Moose if he’ll be his date to his dad’s wedding. Kevin’s aware that this is a public event and that Moose hasn’t yet come out to his father, but he thinks it might be time as the two of them have been together since the start of summer. While Kevin enjoys their clandestine meetings, he can’t help but think of all the things they’re missing out on, such as spending the night together. Moose would like to but he’s too scared. Their time together comes to an end as Major Mason and the other cadets enter the room. He informs them that the meeting with the Navel Academy recruitment officer is about to start.


Moose asks Kevin if he put Cheryl up to the announcement

Moose and Kevin listens from the classroom as Cheryl takes it upon herself to make an announcement. As Riverdale High’s first openly lesbian Student Body President, she announces that the launch of a new club, an LGBTQIA alliance, with the mission to find and support their fellow queer and questioning students. This weeks blind item will be on theme. Cheryl exposes that an all-American RROTC cadet is afraid to come out of the the closet. This concerns Moose and Kevin. Moose pulls Kevin into the hallway to ask if he put Cheryl up to that, which Kevin denies having down anything of the sorts. He’s opposed to publicly outing people. Moose worries that people will start to guess it's him that Cheryl was referring to. Putting aside what Cheryl did, they’ve been together for a while, Kevin can’t keep this relationship going if Moose refuses to come out the closet. And so, Kevin gives Moose an ultimatum. Either he comes out to his dad or he and Kevin have to break up.


Moose and Kevin kiss after Moose came out to his father

Moose surprises Kevin with a kiss as the school day begins. He proceeds to reveal to Kevin that he came out to his dad. He was quiet and weird at first, but then seemed to come to terms with it. They then went to Pop’s and had a meal. This means that Moose can now be Kevin’s date to the wedding, and more importantly, they can spend the night together.

Cheryl approaches Moose at Pop’s to apologize for outing him. She admits that it was wrong and that it was a personal decision she never should’ve taken from him. Moose accepts her apology. And while what she did wasn’t right, it ended up benefiting Moose as he’s out with his dad now. On top of that, he and Kevin are finally going to spend the night together in the bunker. Cheryl suggests that Moose bring a fresh change of sheets as a lot of people have had sex on that cot.


Moose and Kevin lay in bed together

Kevin fills the bunker with candles in preparation for is night with Moose. Moose arrives with candles of his own and the two begin to kiss. Moose and Kevin lay up next to each other in the bunker. Part of Kevin thought that it was never going to happen, but he’s glad it did. The bunker door then opens. Kevin initially believes it to be Betty, and so he tells her that he’s reserved the bunker. However, he and Moose get out of bed to discover that it’s not Betty, but in fact the Gargoyle gang. They shine red lights in Moose and Kevin’s faces before attacking them.


Moose and Kevin are forced to drink from the chalices

Moose and Kevin are taken to a clearing, where they Gargoyle King awaits their arrival. Before them sits two chalices. The Gargoyle King wants them to flip for their fate. When Moose refuses to play along, the Gargoyles pull out knives as incentive. Should they refuse to play, they’ll be killed. With no other choice, Kevin decides to go first. He flips the coin and just as he prepares to sip from the chalice, the Gargoyle King is shot by an arrow, fired by Cheryl, who along with Toni, Tom, FP and his deputies, bring an end to the ritual. They unmask the Gargoyles and much to Moose and Kevin’s surprise, they’re the RROTC cadets. They were being lead by Marcus Mason, who is disguised as the Gargoyle King.

Season 4


Jughead and Moose are roommates

Moose greets Jughead with a hug upon discovering that they’re roommates. Moose now goes by Marmaduke. After his dad was arrested for impersonating the Gargoyle King, Moose’s entire life shattered. He had a nervous break down and stayed in a facility for a few months. When he got out, he decided to take a year off before attending Stonewall Prep to play football. He asks Jughead to keep his secret as his life would be ruined if the other students found out who he really was. Moose warns Jughead to be especially cautious around Bret, who unbeknownst to Moose, stands listening in the doorway. He welcomes Jughead to Stonewall Prep and escorts him to the seminar.


Moose explains that he's bisexual

Jughead interrupts Moose's hook up with Donna Sweett. Jughead assures her that he won’t tell anyone, but she doesn’t care if he does, as she isn’t ashamed of anything she does. However, she does advise Jughead to watch his back around Bret. He’s the son of a diplomat, and because of this, he thinks he can do whatever he wants. Bret fights psychologically, and he’s not afraid to play dirty. Jughead heeds Donna's warning and then apologizes to Moose for barging in on him, but he was under the impression that Moose was gay. Moose explains that he likes guys and girls.


Moose reads the article about his dad

A news article from the Lodge Ledger detailing the events of Moose’s father impersonating the Gargoyle King are plastered all throughout the halls of Stonewall. A mortified Moose realizes his time at the school is over.[25]

Moose is confronted by Jughead after finding a pamphlet for the Army. Moose is contemplating dropping out of high school and joining the Army. Jughead tells him that he can’t let Bret win by leaving, as that was his goal when exposing Moose. However, Moose expresses that’s easier said than do as he’s having to endure the other students calling him "Gargoyle boy."[26]


Moose returns to Riverdale

Moose meets with Betty and Alice at Pop’s and asks him who gave him the army pamphlet. After the article about his past in Riverdale spread around school, Mr. Chipping suggested that Moose look into the military. Alice asks what is Moose’s connection to Mr. Chipping. Moose reveals that he was recruited by Chipping to play football at Stonewall Prep. After the story about Moose came out, he was encouraging Moose to leave. Until Halloween night, when it became more than a suggestion. He practically shoved Moose out the door. Not to mention the videotape that Bret made of Moose having sex in their dorm room with a classmate. He was lording it over Moose and threatening to release it at any minute. He said it would be a good addition to his collection.[27]

Physical Appearance

Moose is an attractive young man with tan skin, hazel eyes, and dark brown hair. He is tall, with an athletic build, due to his place on the football team. He doesn't put much thought into his choice of clothing, typically a jacket or hoodie with jeans.


Like Reggie, Moose embodies several characteristics usually associated with the stereotypical jock. He doesn't appear to be very smart nor does he seem interested in school. Football, and concealing his true sexual orientation are his biggest concerns. However, he has been known to have a more compassionate side; volunteering to help work at Andrews Construction following the exits of Fred Andrews' crew.

Moose is also very heroic, as he risked his own life to save Midge Klump, his girlfriend, from the Black Hood. Due to his sexuality and the conflict he faces because of it, he is quite understanding when it comes to relationships with other men, and can be very comforting towards those who share a similar struggle.


Other Relationships

Midge Klump

Guys, I gotta tell you something. The night of the show, Midge and I got into a fight backstage cause she admitted, she was seeing someone else, behind my back. {...} She let it slip that it was a Serpent.
— Moose to the Bulldogs[src]


Moose and Midge at Pop's

While it remains unknown just how long the two were together, Moose and Midge were boyfriend and girlfriend up until her untimely death during the school musical, though neither of them were faithful throughout the duration of their relationship. Moose wrote Midge’s name in the book of conquests and had a brief romance with Kevin Keller shortly before Midge began cheating on him with Southside Serpent, Fangs Fogarty. However, they did seem to care for one another nonetheless, proven when Moose shielded Midge from the gunfire of the Black Hood while at Lover's lane.


  • According to Kevin, Moose's "appendage" is considered "horse-like."[1]
  • Neither Moose nor Reggie Mantle were cut from the football team the way that Chuck Clayton and a number of other players were, when the scandal of Chuck's "playbook" broke, despite their names being clearly visible in the book.
  • Moose drives a 1965 Chevrolet Chevelle Malibu Z16, which license plate is: 3CL 678 as seen in "Chapter Fifteen: Nighthawks". However, he drove a 1972 Dodge Dart Swinger in "Chapter One: The River's Edge".
  • Moose had blond hair and brown eyes in the comics.
  • Just like the TV series, Moose is in a relationship with Midge Klump in most if not all comics iterations. In 2015 "Reggie and Me" it is revealed that Moose is the eldest of five children.
