So you fags probably don't know this but the director of The Thing confirmed SOMEBODY was infected at the end of The Thing. I'm convinced it was Childs.

Childs was alone and was next to the generator room where the Blaire creature was hiding. The coats on also change between shots suggesting Childs was infected and the thing tore through his clothes, also Childs wasn't the kind of guy to just run right into a snowstorm. There's little to suggest Macready was an imitation because he blew up the creature at the end. The reason Macready acts weird at the end of the movie is because he knows Childs isn't really Childs, he confirms it when Childs shares a drink with him, which is why he's laughing at the end.
