He should say that he's glad she was there, too. It's what anyone who isn't a complete fuckwit would say. Luke isn't sure that it would be true, though, and it doesn't seem right to pay her back for helping him by lying to her face. He almost laughs, wondering he started caring about what's right. Though he's heard it said that a near death experience will change anyone, he doesn't feel very different at all. Same asshole that he's always been, down one reason to live.

"You don't have to stay, you know." He can only imagine that she's still here out of some sense of obligation and that seems, to him, fucking crazy.
