[He shrugs disarmingly, with that same small and careful smile. And in part in deference to her, he glances down instead of meeting her eyes--but mostly it's a selfish instinct. His instinct to do good--to be cheering, to be a distraction--doesn't outstrip the slight embarrassment at genuine emotion. Genuine emotion is Not Cool. But it's not as if he can help himself at the best of times--and anyway, this is Tyke. That makes this different.]

Dunno, actually. I thought I'd plan it out on my over to wherever you are. But it would be fantastic. Maybe indoor fireworks. Maybe I'd make your floor into a flowerbed. Or I could teach your dogs a waltz, but I sort of want them to like me? So I might forgo that one; sorry if you're now looking forward to seeing it. Or I'd make it snow, I've been practicing snow--it's not even cold--or I can do spring. Summer is more difficult, but I'm working on it as well. Or I could do normal things as well, punch your shoulder or talk to you or whatever.

[He shoots her a glance and a slightly more rueful smile. What a girl, that Sirius Black!]

More or less whatever you want.
