"You might not want to look to your world for prosthetics." Bones has Opinions about that unsanitary wreck Thor stumbled into the Nexus with. None of them good. "You could do worse than to ask around here, or let me see what we can do for you if the captain will make an excuse for us to do it."

Bones is well used to having to do his job even in the midst of tragedies he shouldn't be functional for. If he can lead the medical wing after logging his best friend's corpse among the fallen he can damn well take a look at that scowling lady's head wounds, her mute security specialist looking friend, and talk to Thor about looking for something for his arm despite hearing about massive genocide on a world that isn't his.

Not because he doesn't care, because he does. More than most. But because it doesn't stop him from having a job he needs to do. McCoy's certainty helps keep Jim steady. Helps him draw his professional demeanor tighter around himself while Thor looks so lost. The man may be a god but Jim is well used to leadership. He makes himself look as confident as he can.

"You need a bottle of water and to make sure you're not reacting poorly to that hypo Bones gave you. Let us handle this part. Just take a moment and...well. I'm not fool enough to think rest will come easily for you, but you do need to just take a moment before you set yourself off again."
