[Billy feels some of the tension ease out of his shoulders as the conversation slips back into playfulness; it's not like it made him uncomfortable or anything - far from it, because he loves when Teddy gets that look on his face, or touches him that way - but he was so unprepared for it at that moment that it's a relief to be back to what's familiar. They've been having these moments more and more often lately, and he loves them as much as he fears them. They bring to mind a question that has been on the tip of his tongue for months, only held back by the walls of doubt known as "too soon" and "this is ridiculous", and a healthy dash of "what if the answer is 'no'?"

And lately, more prominently, the question is also, "what if he says yes?"

Of course it would come to mind here and now, at a wedding. And it's their night, Tony and Pepper's, and he'd never take that from them, so he's glad to feel that moment and let it slip past him yet again.

But... but. It's just a thought.]

Hmm... I think it'll do, yeah. I mean, it's one part punishment and one part present, a couple of strange and stubborn geeks like us being stuck together.
