What's wrong with him. He almost feels like laughing, dark and bitter and morbidly amused, because the answers to that question could fill a damn book. And it's directed at him so bluntly by someone who is freaking green. And he thought everything felt surreal before.

"Oh, y'know." He shrugs, head thumping back against the door with a dull, decisive clunk. "Just a little green."

Is he delirious? He actually found that hilarious, so he might be. All Sam can manage is a mildly amused snort as he closes his eyes again and tries not to feel violently sick or pass out.

"Could ask you the same," he continues diplomatically. "I've never met anyone who's literally green."
