So I'm still thinking over specifics, but here's some tentative things so far!

One idea I've been mulling over has been a dysfunctional study group like in Community. So let me know if you want in? I'm actually mulling over whether Kurt or Lee would be my character in said group.

-Aang: Will probably be on the gymnastics team? Still thinking out specifics. One suggestion for Avatar House has been a bunch of rich kids.
-Rock Lee: He may be a member of the football team and/or a swim team. A contender for the study group, probably working to balance athletics, academics and an energetic social life.
-Kurt Wagner: Possibly will be similar to canon. A chill student who likes to be like a party animal. Could end up fratting it up and could be part of the study group. Might be part of the football team if Lee isn't.
-Jade Curtiss: A snarky Chemistry professor. Will sigh at any students offering to "Break Bad" with him.
-Mytho: Probably will be a little like canon minus all the supernatural/fairy tail stuff. He'll be a star ballerina who's likely popular on campus.
