Fighting the grin spreading over his face would only end in a stupid, twisted half-smile ... so he let it go. She was too close to see anyway, wasn't she? It was great to have her this near, without having to worry about anything - except that it felt like a bloody lifetime since the time he'd kissed her, and that hadn't ended very ... Well, it hadn't ended any way, had it; just part of the gloomy blur that he'd been in when the Horcrux had still been with them, and he'd left. And now he'd come back, and Harry thought of her as a sister, and he didn't know why it all had to be so complicated. It didn't feel like it should be.
When she didn't pull away, he decided that maybe it wasn't. He tilted his face slightly to kiss her, more confidently than he felt. Her hands around his were reassuring, and he held to them securely.
