They make out. Nick fucks everything up, like stat.
Nick: "Hey, is this for real?"
Carrie: "I don't know."
Nick: "Are you just handling me? You Keeping me close?"
Carrie: "Brody, I don't know."
I love that. Even Carrie is mystified by Carrie. Shit, I don't know. Kind of?
Carrie: "...I don't want you to feel used."
Nick: "You know what, I do feel used. And played, and lied to. But I also feel good. Two minutes with you, and I feel good. How do you pull that off?"
Somehow, and I can't see it anywhere in the words, but somehow in there he managed to call her a slut. I remember distinctly that he implied she is a big old whore in that little speech. But I'll be damned where it went, now that I'm looking at it in print. Acting. Actually both of them, in this scene, are on fire. No: Electrified. Like their hands have an agenda their brains don't even really know about yet. Like sideways gravity shoving them together.
Although I think the answer to the question of why he feels good when he's with her is that she does not judge him, she's the one that sees all the parts and down to the real sick shit and that she knew he was going to kill her up in that hotel room, she fell in love with him when she was the only person that knew he was a terrorist, and she still doesn't care about any of that, because he makes her feel good too. It means that he is universally loved by someone, which feels good, but also means that her moral character is slipshod enough that she wouldn't have a leg to stand on if she did decide to judge him.
People get real cagey when you start talking about why people are with the people that they're with, because that can go gross on you so fast, but that's part of it: You want the person you think you deserve. And for different reasons, both Nick and Carrie love about each other a very sad thing, which is that they are kind of the Worst. If you told me you were dating a member of Al Qaeda, I don't know that I would be able to restrain myself from giving you a pep talk about your worth as a person and as a romantic prospect. You know what I'm saying? If you said to me, "Hey, I think I'm going to start dating my stalker," there would be several conversational detours before arriving at, "You should leave your wife if you're going to do that." Possibly you would not come away from either conversation with the feeling that I was being a supportive friend.
