[For a long moment, Billy looks torn. There's so many answers to that question, and not enough words in his head to articulate it properly. Finally he sits up, tucking his legs underneath himself and pressing his body against Teddy's, his head on the blond's shoulder, his hand on his chest. There's a hundred conflicting emotions showing clear as day in his expression, and he's not sure he can face Teddy with them just yet. It's too raw, too new, and while it's not like he thinks that Teddy's going to judge him for it, he just doesn't want to be worrying his boyfriend for nothing.

Too late for that, his cynical subconscious is telling him, but he shoves it off. This is more comfortable anyway, and it means they can have a good cuddle. It's a perfectly acceptable reason to move.

There's still the matter of Teddy's question, though... and after another pause, he breathes in deeply and gives it a shot.]

...I don't know. I wish I did, but... I haven't sorted it out yet.

[That's a weak answer, he knows, so one more pause and he tries again.]

I know a couple of things. I know it wasn't her. Something drove her to do that. She was an Avenger, a hero... I can't imagine she'd do something that extreme on her own. But that still doesn't answer what it could've been. Whether it's still out there, or it's still affecting her or... whether it could do it again. With someone else.

[With me, he doesn't say, but Teddy probably already knows he's thought of it. With him having inherited Wanda's powers, it's a natural concern.]
