Study Questions and Answers

1. How does Aly’s profession as a nurse influence her reaction to Brad’s death?
Aly explains that she sees death weekly as a nurse, so the act of dying does not shock her. She even finds relief in seeing a “bad” person die, contrasting with the senseless losses she normally witnesses.

2. Why does Josh resist the idea of asking Nico for help, and what convinces him?
Josh initially hesitates because asking a mobster feels risky and illegal. He agrees after Aly outlines the dangers of amateur body disposal (fingerprints, teeth, fire) and because he wants to avoid jail and media attention. He says he will “do whatever they want” to stay free.

3. What does Josh mean when he says he has worried about becoming a killer “since I was a child”?
Josh implies a long‑repressed fear that he might be capable of violence. He refuses to explain further, saying it is “the stuff of people’s nightmares.” This line introduces a major unanswered question that will likely be explored later.
