"Why?" she asks, not stopping to think about whether it sounds too blunt or not. She doesn't know why Billy would have to resort to stealing - he certainly doesn't strike her as the type. She thinks he'd probably blush and apologise too much to be any good at being a thief, so the information surprises her.

"You used to steal stuff?" She's not judging, she's just confused. It's a side of Billy she hasn't ever seen before and she finds it interesting.
