Somehow the luxury of letting a patient recover hasn't been explained well enough to him (surprise), so the shame passes quickly enough for confusion. Oh, right--he's in medbay. And if Poe says that'll get him in trouble, he definitely doesn't want to! So he tries to relax again, clearly with some effort. "Okay. I can stay." He tries not to sound too relieved at that.

"Hungry? Yeah, I am." Thirsty, well, not compared to being on Jakku. His mouth is plenty dry, but it's been way worse. But he can always eat. Growing up on rations will do that to you.

And then, to his dismay, Finn yawns again. Come on, he's been asleep for a whole week! But even just talking to Poe is an effort, and as much as his mind is skirting the edges he's beginning to realize he was hurt more than he probably wants to know.
