We've done Thor, and rewatched at the cottage, so she is going in with everything except The Hulk movies. She has done her Marvel 101 course.

Yeah, I don't think Loki was right in the head by the time the Avengers rolled around. I mean, more so. Whedon says he got messed up falling through the abyss at the end of Thor. There's also the theory that he's brainwashed, too, due to his eyes being blue in The
Avengers and green in Thor. But I don't know, maybe Hiddleston just got sick of the contacts.
