The dust had settled in the rubble, though the electric crackling that continued to rain down from time to time was disconcerting, and up above black smoke twisted through the air. Coulson, relatively safe in a little pocket within the mess, had been busying himself by constructing a makeshift splint from reclaimed rebar and his belt. It wasn't pretty, but it allowed him to start slowly pushing his way through the broken building.
The voices in his ear had stopped, and the silence was almost worse than the groaning of the rubble shifting overhead. It took some time, but eventually he'd managed to break out into the light.
Once he'd crawled out he didn't make it much further, sitting in his dusty suit, leaning against what was left of the building. That wasn't so hard. He'd just...close his eyes for a minute...and then he'd be set.
