The Avengers are returning from battle, and Tony has a broken arm/leg (can't remember which). The Avengers get called back out, but obviously Tony can't go back out. Bucky is there, and he is not very fond of Tony. However, he offers to look after an injured Tony while the others go back out. While the Avengers are out, Bucky starts attacking Tony, and I remember at one point Bucky has Tony on the floor and is planning on violating him. Right before he does so, he gets pinned to the wall by a pissed off Steve and all the other Avengers form a protective wall around Tony. I can remember Steve punching Bucky, and the story was established Stony.
Can anyone find this?
