Principal Weatherbee began the school day by announcing their plans to continue moving forward with the pep-rally, despite recent events. As Sheriff Keller spoke on the status of Jason Blossom's death, Weatherbee briefly noticed Archie Andrews lurking outside his office.
Later that day, he approached Archie, requesting that they speak for a moment. He first acknowledged Archie's satisfactory position within the school, such as Varsity football and AP music tutorials. He quickly moved on to the real reason he requested Archie's presence, the look they shared earlier that day, he wondered why Archie wouldn't meet his eyes, suggesting that he may be hiding something about Jason.
That night, during thePep Rally, he hands the mic over to Mayor McCoy. The next day, he and Sheriff Keller arrest Cheryl Blossom during class due to something that was revealed during Jason's autopsy. 
Principal Weatherbee and Sheriff Keller escorted Cheryl to his office for question in the murder of her own brother, Jason Blossom. Cheryl claimed that she didn't kill Jason, however, she admitted to lying about what took place on the 4th of July. The truth is that they went out there to fake Jason's death. They made it to the other side of Sweetwater River, in Greendale, and they parted ways, but she recalled hearing a gunshot just before.
The following day, Archie came forth, admitting that he was at the river on the 4th of July, and that he heard a gunshot. Weatherbee watched quietly as Sheriff Keller did the interrogating. The only thing useful they learned from Archie was that Cheryl's claim of gunfire is true. 
Jughead Jones was taken into custody upon the discovery made by Sheriff Keller, which were that his fingerprints were on file for a previous incident. After entering The Blue and Gold in search for Jughead, Weatherbee and Keller found his murder board, which only made matters worse. 
Homecoming and Jubilee
Principal Weatherbee denied Betty Cooper's request to delegate a percentage of her decorating duties for the Homecoming to Ethel Muggs. She made a commitment, one that she had to honor, especially when considering that this Homecoming was also reunion weekend, in which former graduates would return to Riverdale High School to revisit their youth and make up for lost time. The night of the dance, Mr. Weatherbee and Mayor McCoy requested Betty's assistance throughout the evening, however, she was fairly unavailable, leaving the task of walking Mayor McCoy up to the stage on him.
Following an altercation between Jughead Jones and Cheryl Blossom in the school's cafeteria, Mr. Weatherbee requested Jughead's presence in his office, where he interrogated him over the murder of Jason Blossom, before letting him go. Later that night, he called Fred Andrews, and suggested that Jughead finish the rest of the semester from home as he was concerned with Jughead's safety after the incident with Cheryl. The other students could react in a similar fashion which would cause unwanted problems.
At Mayor McCoy's request, Mr. Weatherbee called Archie Andrews and Betty Cooper down to his office, where they discussed the opportunity of the two teens being featured as the town's heroes at the 75th Anniversary Jubilee. They helped bring peace and justice to their streets once more, and even though that's not exactly what happened, Betty claimed, Weatherbee urged her to allow the Mayor to finish her proposal. A couple days later, he attended the Jubilee, and following the performance of Josie and the Pussycats and Archie, he clapped along with the rest of the crowd as Betty gave her speech pertaining to the crossroads Riverdale was facing.
Mr. Weatherbee entered the classroom with tragic news to share. He revealed to the students that Ms. Grundy, who was the music teacher at the school last semester, was found murdered in her Greendalehome the prior night. With some of them being students of her's, like Archie Andrews, he could imagine that the news would be difficult to process. Archie, who is overwhelmed with pain and fear, suddenly got out his seat and exited the classroom.
Endorsing the Red Circle
While walking the halls of Riverdale High School, Mr. Weatherbee immediately noticed that all the lockers were covered with flyers, instructing those that are scared or in need of protection to call The Red Circle; a group watch organization being headed by Archie Andrews.
The following day, Mr. Weatherbee joined Sheriff Keller and Archie by the lockers. The Sheriff then told him about Archie's private army, which much to his surprise, Mr. Weatherbee was fully aware of. He endorsed the movement, informing Sheriff Keller that the Red Circle was, in fact, a school club. Archie had shown tremendous initiative. Mr. Weatherbee wouldn't fault him for wanting to protect his fellow students.
Disbanding the Bulldogs
After hearing of the video that the Red Circle posted online, where they threatened to hunt down the Black Hood, Mr. Weatherbee called Archie down to his office to express his discomfort with Archie's sentiment and to inform him that he was suspended from the football team, effective immediately. The doubling down on that by disbanding the team entirely until the Red Circle was brought to an end. If Archie hasn't written a signed letter apologizing to the Riverdale High community by week's end, his suspension will begin and will continue until he complied. Care to rethink your position, Mr. Weatherbee asked Archie, to which he replied that they all have to do what they think is right, meaning he had no intentions of disbanding the Red Circle.
Mr. Weatherbee and Sheriff Keller interrupted Dr. Phylum's class to pull Archie out in the hallway after getting a tip from a bodega owner on the south side that a Riverdale High School student with red hair was waving a gun around outside his shop. Archie claimed that he was in his garage working on some songs. Nevertheless, given Archie's behavior over the last several days, he and the Sheriff believed that a look in Archie's locker for any weapons or contraband was warranted. With Archie's father having already been informed of the search, Mr. Weatherbee instructed Archie to open the locker or else he would. Inside, they found a black hood, greatly resembling the one that Archie previously described.
Souhtside High Transfers
Mr. Weatherbee announced over the intercom that effective immediately, Southside High was shut down, and its students would be transferred to other schools in the district, including Riverdale High. He believed that the soon to be released statement would address their concerns, as well as their parents'. While he was sure that many of them had questions, it went without saying that they were welcoming the transfers with open minds, hearts, and arms.
Later that day, in the student lounge, as the newcomers were becoming adjusted, Mr. Weatherbee called them out into the hallway, in search of the culprit responsible for defacing the school's seal with a spray-painted on Serpent. Next to Weatherbee stood Reggie, who the transfers, along with Veronica, suspected of being the actual vandal. Despite the Serpents pleading their innocence, Weatherbee continued to accuse them of vandalizing the school seal. His suspicion only grew as with Reggie in his ear, who claimed that the Serpents were doing what they do best by tagging their turf. Having fallen victim to Reggie's lies, effective immediately, Weatherbee outlawed gang behavior of any kind. As of that moment, Serpent jackets would no longer be tolerated and tattoos were expected to be covered. Possession of any gang paraphernalia would lead to immediate suspension.
The next day, Weatherbee was forced to break up a fight between the Serpents and the Bulldogs in the student lounge. After pulling the rivaling groups apart, he gave each of them a week of detention. However, he didn't stop there. Weatherbee looked to Jughead, reminding him that gang paraphernalia, more specifically his jacket, had been banned. Should Jughead refuse to take it off, he would be suspended. In that case, Jughead took the suspension as he walked out the office with his Serpent jacket still on.
Mr. Weatherbee called Betty Cooper and Jughead Jones down to his office to confront them about Jughead's article attacking General Pickens. There had been a steady stream of outrage since the publishing of the article, most recently, Hiram Lodge's lawyer, Paul Sowerberry. He called to alert them that they were considering taking legal actions against the Blue and Gold on the grounds of defamation of character. Effective immediately, both Betty and Jughead were suspended from the newspaper staff. They were given a day to clean out their things.
Mr. Weatherbee was approached by Betty Cooper and Jughead Jones with an article that they were hoping the Blue and Gold could publish. Unfortunately, Mr. Weatherbee refused to publish Jughead's article as he didn't condone the malicious takedown of a fellow students' parents i.e. Veronica.

Later that week, Weatherbee exits his office to find that the students, from both the North and Southside, have united in a show support of the Southside students who are being wrongly transferred. They are all wearing Serpent jackets. 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 Weatherbee, Pop Tate, Sweet Pea, Josie, Moose, Veronica, Reggie and many others.

A few students in particular catches the sheriff's attention. When he asks where Josie was during the time of the breakout, she claims she was alone in the music room. Sheriff Minetta will be looking into all their alibis. As he continues to antagonize Josie, she suddenly has a seizure. Cheryl rushes to her aid, catching Josie and telling the sheriff to back off.
Following a mass seizure, Principal Weatherbee announces over the intercom that they are closing the student lounge. Accompanied by at least half a dozen men in blue hazmat suits, Weatherbee begins rounding up the "infected". When Weatherbee points out Veronica, she makes a run for it.
Principal Weatherbee later holds a school board meeting in his office. Penelope, Alice, Hiram, and Hermione are in attendance. Penelope insists that the school be shut down until they know what is causing the seizures. Principal Weatherbee informs her that they’re taking as many precautions as they can. What they should be doing Penelope says is tracking down patient zero and running every possible test on them. Alice cuts Penelope off, stating that tonight’s discussion is about that fate of Riverdale High. Hiram interrupts as he is in favor of shutting down the school, as are most parents given the fact that five more kids have suffered seizures just that afternoon. Which is why Hermione will be signing an executive order shutting down Riverdale High until it is deemed safe. Veronica and Cheryl interrupt the meeting to reveal Hiram's master plan, the expansion his ever-growing drug empire, which now consists almost exclusively of Fizzle Rocks. Hermione questions what Veronica’s talking about. Hiram decides to address all of Veronica's point, completely dismissing all claims. Penelope then comes to his defense before collapsing to the floor and seizing. Hermione and Alice run to her to assist.
Mr. Weatherbee welcomes Archie back to Riverdale High as he continues his transition back into his life. Weatherbee advises him to be realistic in terms of his goals.

Jughead and Toni profess their innocence as neither of their gangs cook drugs, nevertheless, Jughead gets one more strike and then he’s out of Riverdale High.
Principal Weatherbee is approached by Mayor Lodge after discovering that this year’s musical is Heathers, which focuses on teen violence and suicide. Hermione explains that this is a terrible idea given the tragedy of last year’s musical. Kevin and Evelyn are there to maintain their stance and see to it that the play goes on. While Heathers deals with teen alienation and desperation, it’s characters however long for simpler and more innocent times. Its ultimate message is a rejection to nihilism. Kevin and Evelyn then proceed to sing the lyrics of the first song in hopes of convincing Hermione that the musical is in everyone’s best interest.
Kevin reveals to Weatherbee and Hermione just how clueless they are in regards to what the students are dealing with. In the classroom sits Josie, Archie, Reggie, Sweet Pea, Fangs, and Evelyn, who all proceeds to break out in song and dance, leading Hermione to questions if they’re all truly this miserable. Kevin explains that there’s also Cheryl, who’s floating above it all as Heather Chandler.
Betty goes to Weatherbee with the photos she took from the Gargoyle Chamber of Evelyn, Kevin, and Fangs surrounded by members of the Farm. Betty claims that the musical is being used to indoctrinate students into a cult. From Weatherbee’s perspective, it looks like they’re simply rehearsing. Betty insists that the photos capture some kind of ritualistic ceremony. However, Weatherbee would beg to differ. The Farm is a fully sanctioned club, approved by Weatherbee after he read Edgar’s doctrine. Which Weatherbee found to be fascinating.

Edgar explains that everyone Betty cares about is in the room, her mother, sister, best friend, cousin and sister. In unison, the Farmies recite "Join us."
