Vash actually looked apologetic when Wolfwood stared at him. He wouldn't have prioritized possible survivors over the teenager, but the thought of checking had occurred to him.

He also hummed in agreement with Wolfwood's words.

"You can't help them right now, I'm sorry. We'll drive a ways off, then he'll come back and check, and I'll stay with you to help. Just close your eyes and focus on resting for a bit." Between them on the bike, not getting away. (Vash thought he had a bandana or something like that in his pocket, might make things easier on Wolfwood later.)

"Things are complicated and you are not where you were, the whole place has been moved. We'll need to explain, and then you can think of helping. All right?"
