"It's not a crab hand!" Wikus snaps. Crabs have claws, not tentacle fingers, after all.

He takes a breath to calm himself and runs his human hand through his sparse hair. The guy is helping him, after all, he should probably be more thankful. It's more than any of his friends back home did for him. Not that he had a lot of those...

"No, it's- thanks, I should be fine." He holds his hands out for the first aid kit. He's not sure how he's going to deal with the spots on his back, but he's feeling pretty self-conscious about removing his shirt in front of Tony.
