What I find most interesting about this, and that no one has commented on that I've seen, is apparently Don Cheadle/ War Machine has made the jump from the Iron Man franchise and into the Avengers? Also, even though she's not with S.H.I.E.L.D. anymore, Maria Hill is apparently still throwing down with the big hitters. My guess is this is a carry over from her role in Winter Soldier. Regardless, i love this scene.
