Peter's eyes widened at that comment, but he didn't know what to say about it. The idea of his friends wanting to kill people just made him want to cower and hide.

It's only been two months, but it's been two hard months, and I've-- I've gotten through them without my wife and without two of my kids and two of my best friends and I feel-- I just feel separate from them. I feel like I'm being disloyal to them, though. Mostly I just... I feel like an awful husband. But what does it say about how similar Petunia and I are, really, if she hated it here and I... I like it?"
