"I need an escort to leave my cell," Tav replies quietly, gesturing with his head toward the two piratey looking men standing in the corner. "I doubt my friends would allow me to leave the Gallows without permission of the captain.

It's miserable and he hates it, but he's still trying to cope with it.
