The girl's words are still strange to him, foreign in the same way her accent is--she doesn't have to give Credence anything, no one ever has. No one owes him, nor should they think of him, in his opinion, he's simply one to exist and nothing more. He's used to it.

"Are we allowed to go?" He asks, and while there's no more confusion, it's still tempered with caution. Not of her, but rather what's out there.
