[ the tightening of his jaw indicates that whether or not she actually would sell him to the hutts (he's pretty sure she wouldn't, honestly. not by the amount of "fun" she seems to always be having), he doesn't really appreciate the "kindness."

he steps back instinctively, wanting to maintain as much distance between them as possible. even with practically no hope for escape, his muscles are still always tensed and ready to break out into a run at the slightest opportunity. every moment has the potential for him to grab her lightsaber and almost ignite it at himself again. ]

Can't say I'm much flattered by going from prisoner to slave. [ symbolically, anyway. from the looks of things. ] Seems like a downgrade to me. 

[ he didn't like the idea of belonging to her in some tangible official form. as just a prisoner, he had the hope of maybe somehow, someday, escaping and being free. it seemed more and more distant and impossible, but he still used that tiny little ember of hope to keep him warm at night. now... something about it felt harder. further from his grasp. ]

I hope you got a return policy on that.
