I go back and forth who would be Clint's bff, there's arguments for all of them. I think he and Steve would bond over the military stuff. I think Tony and him would prank each other and have fun fun being snarky. He and Bruce would bond over both knowing how it feels to not be in control. And then Thor, obviously with the whole Loki thing would have a lot to talk about. I think that's the beauty of Clint, and how the movies have been a little vague about his character, he could work with just about everybody.

I'm completely with you about the side characters. I get so excited for sometimes really minor characters and my friends think I'm so weird. In the books pretty much every Cullen was my favorite but I especially loved Jasper, Alice, and Carlisle (which I realize is pretty much half the family, lol). Jasper and Alice's relationship was perfect, I loved the hints of how strong their bond is. Pretty much all the fanfiction I read for that fandom was Jasper centered. I refused to read Edward/Bella because it was in the books so I didn't really care. It got to the point that I actually got into Jasper/Bella, not shipping it canon wise, but it was just fun to read all of the fanfiction, and it was fun to see all of the back stories.
