Meanwhile, Ray decides to leave town after Valerie buys the Peach Pit After Dark from Steve's father for her own use. Peter tempts Andrea to stay out late at the hospital with him, so she gives in to his requests to sleep with him. Also, Dylan is tempted by Valerie to fall off the wagon again. Seeking answers to his path in life, Dylan tracks down and finds his rehab friend Charlie Rollins, a motel owner, where Charlie tells him his idea of writing a movie screenplay to make money and asks Dylan for a little help.
