The elevator? Really? Happy had no idea how the real heroes put up with this kind of thing, but then he also couldn't imagine that villains were ever quite so annoying. Or macking on his girlfriend-ex-wife. It was that thought that spurred Happy into a renewed motion and he bolted down the hall, footfalls falling with rhythmic metallic clinks.
Stairwell, there had to be one somewhere. He found it at the end of the hall, burst through the door- much to the surprise of an agent sitting on the stairs- and swung himself up and over the railing. S.H.I.E.L.D. headquarters was a tall building and Iron Man had a long way down. Still, he figured maybe he could beat the elevator. He burst into the ground floor hallway where all activity halted as the entire lobby paused to stare at him in wonder.
"Sorry," he called out and waved a hand for them to carry on and, surprisingly, they did. Weird things happened at S.H.I.E.L.D. Sometimes even weirder than Iron Man running in from the stairwell then stopping to stand with arms folded at the elevator.
