|“||Even though we were twins, I used to demand I have my own birthday party. Until one year, out of the blue, Jason convinced me we had to combine them into one. It wasn't until years later, I found out why. It was because no one wanted to come to mine. And Jason didn't want me to know. He protected me. Every single day. I wish, that day at the river, I had protected him. I'm so sorry, Jay-Jay. We failed you. All of us.||”|
Jason is the son of Clifford and Penelope Blossom, as well as the twin brother of Cheryl Blossom. He supposedly died under mysterious circumstances when he fell from a boat into Sweetwater River on July 4th. But as it turned out, he died a week later around July 11th, when he was shot by an unknown assailant, who was later revealed to be his own father, Clifford Blossom. Prior to his death, he and Polly's intended to run away together after learning that she was pregnant with twins, who Polly later named Juniper and Dagwood.
After his body was found, Jason was buried in the cemetery on the grounds of Thornhill, which was later dug up by the Farm in efforts to gain Cheryl's loyalty. Unable to part with him again, she kept his corpse hidden inside Thistlehouse. However, in "Chapter Sixty-Six: Tangerine", Cheryl was finally able to let go of Jason and gave him a Viking funeral at Sweetwater River.
Nearly a decade later, Jason and Polly are both resurrected by Cheryl when she visited the Sweet Hereafter to rescue her friends.
Jason grew up in Riverdale, alongside his twin sister, Cheryl. Prior to his death, he was in a relationship with Betty Cooper's sister, Polly. According to Betty, he meant the world to her but she meant nothing to him. The relationship ended badly, and Cheryl speculated that Jason was likely the reason that Polly suffered a nervous breakdown and was sent to live in a group home.
When Jason and Cheryl were younger, their mother would take them upstairs into their rooms, where she would tell them bedtime stories about the Sugarman, her very own concocted version of a child's Bogeyman, in an attempt to turn an all-too-real monster into something less. Little did Jason know at the time, the Sugarman was real, and looking to protect them from the danger that followed was their mother, who sent Jason and Cheryl into their rooms whenever he would visit Thornhill.
Over the course of his life in Riverdale, Jason became the captain of every sports team in Riverdale High, working during most summers as a lifeguard at the local country club.
Jason is a moderately slim young man of medium stature, around 6' 1", with pale skin, red hair, and steel blue eyes. Ironically, despite his leading position on the Riverdale Bulldogs, he is not an especially muscular individual. During his high school years, he was often seen wearing his blue and gold varsity jacket though. According to Veronica Lodge, Jason was "crazy handsome," and Cheryl agreed, saying that he was the "handsomest."
As Jason was killed prior to the start of the series, not much information about his personality is known. His personality was deduced through his interactions with other characters. He bullied Jughead at school from time to time. However, according to Cheryl, he was the best brother anyone could've asked for and was a genuinely nice person who didn't deserve to be tortured and murdered. Jason is very protective of his loved ones, especially Cheryl. When they were younger, Cheryl insisted on having separate birthdays from Jason despite the fact that they were twins, until one year, he randomly recommended that they combine their birthdays into one. It was not until years later that Cheryl discovered the reason for this was that no one would come to her birthday. Jason protected her feelings whenever he thought it was needed.

Jason and Cheryl have an unusual, but also nearly unbreakable bond. They are extremely close. Cheryl often describes Jason as her 'soulmate.' Given that they are twins, they'd spent their entire lives together, never separated, and upon Jason's death, Cheryl was left devastated. Jason is very protective of Cheryl and her wellbeing. When they were younger, Cheryl always insisted on having separate birthday parties despite the fact that she and Jason were twins, until one year, he convinced her to combine their birthdays into one. It wasn't until years later that Cheryl discovered that the reason for this was because no one wanted to attend her birthday and Jason didn't want her to be hurt. When Jason learned that Polly was pregnant with his child, they made plans to run away together and enlisted in Cheryl's help to do so. However, he never told her that he was running away with his pregnant girlfriend, only that he wanted to leave and that he didn't want their parents to come looking for him. And so, Cheryl being the loving sister she is, helped Jason run away, however, this ultimately resulted in his death at the hands of their father. And still, even in death, Cheryl remained connected to her brother and went as far as bringing his corpse home and having casual conversations with him for weeks. Later, Cheryl and her mother started a ministry where parishioners worshipped Jason. And when given the opportunity, Cheryl resurrected Jason from the dead.

Jason's relationship with Polly was described as passionate and romantic by some and toxic by others, and ultimately, it ended in tragedy after Jason was mysteriously killed and Polly was sent to live in a group home. Initially, Jason was forced to break up with Polly because his parents didn't approve of their relationship, but they became engaged after discovering that Polly was pregnant. According to Cheryl, Jason was kind and loved Polly, however, Betty claimed that while Polly thought of Jason dearly and heavily valued their relationship, Jason, on the other hand, initially didn't take her attraction seriously, further proven when it is revealed that he only started dating Polly to earn points in the football team's "book of conquests." However, it is implied that Jason eventually started to genuinely care about Polly. This is evident in the book of conquests itself, in which other team members dock Jason points for developing feelings for her. Despite all this, he intended to run away with her. It wasn't until after Jason's death that Polly would lean that they're third cousins. Polly has since given birth to their twins, whom she named Juniper and Dagwood. And much like Jason, Polly also met an untimely end. However, the two reunited in the afterlife and have both been resurrected by Cheryl.
The father-son relationship between Jason and Clifford Blossom is difficult to describe given the events that transpired between the two of them. While little is known of their relationship prior, it is presumed to have been filled with hate and disdain despite the fact that according to Cheryl, Jason was the golden-boy who could do no wrong. Clifford groomed Jason to take over the family maple business. However, Jason didn't share this desire, which led to Jason's demise at Clifford hands. Once Jason learned of Clifford's illegal transportation of heroin to Montreal on the maple trucks, he attempted to run away and start his life over with his then pregnant fiancé, Polly Cooper. Unfortunately for Jason, Clifford learned of his plan to run away and killed him.
The mother-son relationship between Penelope and Jason is mostly shrouded in mystery. It is currently unknown exactly how close they were before his untimely death, but Penelope was devastated to learn of Jason's murder. Notably, Jason was the family heir, who according to Cheryl was the golden-boy. Judging by Penelope reaction to her son's death, she looked looked favorably on him. Although, approaching Jason's death, their relationship seemed to have soured, as Jason was set to leave town, going so far as to fake his own death in order to be rid of his parents.
