who the true father of Sarah's baby could be. Meanwhile, upstairs Sarah's mother finds out that she was raped, with the actual father of the child being Sarah's stepfather. Keith and Veronica come and help, and Keith ends up shooting and wounding the stepfather to protect Sarah. We then return to the point at which the episode began. Arc significance While gathering information on the Class of '79 reunion, Veronica finds out that her mom and Jake Kane dated in high school. In a flashback, Veronica asks Lilly to find out why Duncan broke up with her. The next day, Lilly had apparently found something out and tells her to forget him and move on. Vice Principal Clemmons tells Logan to remind his father the offer he made about donating his boots from one of his hit movies to the school. Logan finds out that Weevil has a tattoo of "Lilly". When questioned, Weevil says that his sister's name is Lilly. Weevil and Logan put their English teacher's car on the flagpole. Only Weevil gets in trouble (he gets expelled), and later on, Logan admits to Clemmons that he was an accomplice. Clemmons lowers the punishment and brings Weevil back to the school.
