When he kisses her, every time he kisses her, but especially these out-of-nowhere, no-sex-involved, everything-I'm-not-saying kisses, Kate stops being confused. For a few heartbeats, everything makes sense. She's still beyond scared, but she knows what she wants. Then it stops, and the doubt creeps in (storms in, smacks her in the face), and she knows she can't have it. He's too good for her. And it's hard, really hard, not to feel like he's kissing her goodbye.
