For 3, I've been working on a Avengers Team Science fic for months that will eventually meet this request to a tee. Premise is: Jane, Bruce, Tony, and Erik are thrown in a room by Maria Hill immediately before the end of the movie and told: we're about to hand the Tesseract off to the Asgardians. Learn as much about it as you can before that happens. You have twenty four hours starting... when I started talking.

Banter and technobabble ensues.
