Jason Blossom

Jason Blossom is a recurring character on Riverdale. He is portrayed by Trevor Stines.

Jason was the son of Cliff and Penelope Blossom, aswell as the twin brother of Cheryl Blossom. He was captain of the school water polo team and a member of the Riverdale Bulldogs. He supposedly died under mysterious circumstances when he fell from a boat into Sweetwater River on July 4th, the last day of summer vacation before the start of the series but as it turns out he died a week later on July 11th.

Early life
Like most, Jason grew up in Riverdale, along side his twin sister, Cheryl. Prior to the start of the series, he was in a brief 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, Cheryl speculates that Jason was likely the reason that Polly suffered a nervous breakdown and currently lives in a group-home.

Season 1
Jason disappeared under mysterious circumstances on July 4th. That morning, he and his sister drove out to Sweetwater River together at dawn. They held hands and walked towards the water's edge. Cheryl asked her brother if he was scared, to which he gave a slight smile and shook his head. The pair rowed a boat. According to Jughead, that was the last certain thing anyone knew, as Boy Scouts stumbled upon a distraught and soaked Cheryl huddled on the rocks near the water. She claimed she dropped her glove in the water and he tried to retrieve it for her, tipping the boat over in the process, thus drowning. However, Moose and Kevin later came across his body, which washed up on shore, while at the lake together. They discovered a bullet wound in Jason's forehead, revealing that his death was not an accident.

The police, led by Sheriff Keller, opened up an investigation into Jason's death and carried out an autopsy on the body. Somehow, the results led them to Cheryl, who went with them willingly, claiming she was guilty. It emerged that Jason did not in fact die on July 4th, as previously thought, but a week later.

When questioning Cheryl, she said that Jason wanted to leave Riverdale and never come back. She helped him come up with the plan at Sweetwater River so that their parents wouldn't go looking for him. They made all the way to Greendale in the boat and then Jason left, saying he would contact her in a month, but he never did.

While Cheryl slept in his bed, Jason appeared in her nightmare as a ghostly figure. Like a Gothic heroine, Cheryl slowly crept down the steps of her family mansion. She entered the main room, where Jason's coffin laid, only to discover that he was not in it, but the roofing of said coffin was riddled with bloody scratch marks. As she turned around, Jason reached out for her throat, Cheryl let out an ear piercing scream in response. Of course, it would soon turn out to be a dream. During his memorial, Jughead and Betty discovered from his grandmother, Rose Blossom, that he had intended to marry Polly.

Physical Appearance
Jason was a moderately slim young man of medium stature, around 6' 1", with pale skin, ginger colored hair and stale blue eyes. Ironically, despite his leading position on the Riverdale Bulldogs, he was not a physically muscular individual. He was often seen wearing his blue and gold varsity jacket though. According to Veronica Lodge, Jason was "crazy handsome", Cheryl agreed, saying that he was the "handsomest".
