Bulma makes a little squeak of surprise as she's grabbed and pulled back, snapping back to attention rather quickly, of course, with the jarring return to 'Earth' or void.. whatever. For a half a moment she looks like she's ready to snap something out about keeping his hands to himself before the situation fully registers, and then she's backing away from the edge a bit more of her own volition, peeking down at where she may have dropped if he hadn't pulled her back.

"Oh, well that's a long fall." Granted, Trunks is here somewhere and probably could've caught her, but - "Guess I got a little caught up in my own head there... thanks."
