Sean Terrence O'Connell Timeline and Summary

Sean's working out in his home gym when his teammate Bobby Duvall comes over. Bobby asks Sean to hook him up with some steroids.
Sean goes to visit his brother Chad, a drug dealer who hooks him up with the steroids, but they're not for Bobby—instead, Sean starts taking them himself.
While making out with Cara one night, Sean realizes he can no longer get an erection. Chad to the rescue: He's got Viagra.
Sean becomes increasingly violent and erratic due to the steroids. He rapes Cara, convincing herself she said "now" when she actually said "no."
Cara breaks up with him. He posts mean things about her on Facebook and calls and messages her constantly, but she doesn't answer.
He finds out Cara's with Dani when he sees them kissing at Mt. Rose.
He follows Cara to Dani's house, stands outside Dani's window, takes pictures of them having sex, and distributes the pictures throughout the school.
Cara files a restraining order against him, and Sean gets arrested; while in jail, he talks out loud to the violent voice in his head.
Uncle Jeff gets him out of jail. He does some community service.
As an act of revenge, he starts dating Aubree, and the two of them engage in PDA in Cara's presence.
When Conner dies, Sean goes to his funeral with Aubree. He realizes he has to get over Cara and find a way to be happy that has nothing to do with a girl.
