Bruce: you talk to yourself when your really into something. He can just barely hear your whispers, and he loves how you get so into things.
Bucky: your always constantly tapping or humming or something. At first he found it annoying, but then he started to miss it after you stopped.
Clint: you get really funny when you get tired. Somehow you start thinking your a great stand up comedian, and you actually are pretty funny when your tired.
Loki: you get so moody when someone does even a little thing to piss you off. It could be that they burnt your toast a little too dark, and it makes you moody for the rest of the day. That is, until he comes and fixes it!
