Curtis, for better or worse, lets himself be manhandled into position. He can't do much to stop Grey anyway, so there's no point in reacting badly over it. The man's not trying to kill him and that's good enough. Hell, he's trying to help him--Which here and now, seems a little more daunting than the threat of death. The kid doesn't know shit about this world and the one of them who does is pretty much incapacitated. Great.

His head slowly rolls to the side to meet Grey and his pantomime show. He's holding a small bottle as if that's supposed to clue him in on what it is. Feeling feverish and his sight swimming with the drug, Curtis can barely make it out, which frustrates him more than it should. It's not Grey's fault, but if he could he would grab the thing himself to get a better look.

Iodine.

"No clue," he finally says. The only thing he knows about iodine is that they would use it in science class when he was in high school to stain slides. He's not sure how staining his cells are going to help, but... "Maybe." There. That sounds hopeful. Isn't it used to help make safer foods? Or at least helped with some kind of cancer right? Iodine is good for some aspect of your life. Whatever, at this point he is too existential and high to care how bad an idea it is.
