...i tricked myself into writing...some of it already, i think. all right, OP, you're the mastermind: do the Avengers (and by Avengers I really mean Bruce and Pepper (and possibly Sam) wind up befriending Matt? Does he manage to ESCAPE ALL THEIR ATTEMPTS AT GOODWILL? how do you want it to end?

(also: i am profoundly unimpressed with AoU - except for SAM SAM SAM - but i am flexible! which avengers line up do you see happening, here?)
