He has been trying to be patient with Sidney, but lately he feels like they don't connect anymore. Atleast, that's how it's been since her mother was killed. One night, the night after 2 teens at their school have been killed, he goes to visit Sidney. Bad Timing! Sidney had just recieved a phone call from the killer and was attacked. She was in the process of calling the police when Billy snuck in through the window claiming he heard screams and came to her rescue. At that moment, a cell phone fell from Billy's hand. Sidney freaked out and ran outside to find Dewey and the police waiting. They arrested Billy and took him off to jail.

Is Billy really the killer? Or is it just coinsidence that he was at Sidney's with a cell phone at the time of the attack? What would be his motive? Just because your girlfriend won't have sex with you, is no reason to kill her. And why would he kill the other teens? Did he even know them?
