Heddon often bullies Jeremy and believes Jeremy is stalking his daughter.Charlie and his friends begin taunting David.

He runs away just as Heddon informs Charlie and his friends of Janice's disappearance and guesses that Jeremy has done something to her.Amy begins to flash back to the rapes and asks David to take her home. On the way, she tells him she wants to return to Los Angeles, surprising him and causing him to accidentally run over Jeremy. David and Amy take him to their home and call an ambulance.
