In the car, Sam receives a call from Beck. (Maybe his ringtone is “Two Turntables and a Microphone.”)Sam is still angry with Beck for turning those three people into werewolves, so he hangs up on him.
The phone call leads into a conversation between Sam and Grace about how long Sam has been a werewolf, and how it happened. Answer: Eleven years ago, when Sam was seven, and he was attacked getting onto the school bus.
Sam realizes something as he tells the story to Grace: “My attack had been no accident. I'd been chosen, hunted down, and dragged into the street to be infected” (44.39).
They get to Grace's house, make out, and... well, let's just say we hope Grace doesn't end up having puppies after what they do with each other.
