While he is lying on top of her, Rachel pulls out a razor hidden in a cigarette box and cuts her arm, which seems to intensify her sexual excitement.

The friends sneak out of the hospital to host a big New Year's Eve party at Rachel's father's house.

As the count down to the New Year begins Rachel starts to kiss back and Toby gets ready in the car to be fulfil his pledge.
