I personally feel like the two men on either side of Bruce need to go off and have sexy times just the two of them, but I absolutely adore this picture for THE WAY YOU DREW BRUCE! That flushed, nervous look! So hot!
Thor just reminds me of a cow. I am not saying he's fat I am saying he is just BIG. I didn't like the movie Thor as much As I liked the Avengers though. WAY better. I think the only thing that made Thor good was that they picked Tom Hiddleston for the part for Loki.
Thor and Banner? I don't really see them as friends, let alone a couple.
Clint and Natasha? I don't think they should be paired with anyone but themselves. Together they would make a good couple.
