It had all happened, as most catastrophes do, very fast and very sudden. You'd both known the building was likely to come down. It was old, unstable even before any bombs went off. That's why you'd had to prioritize 'evacuating civilians' over 'making sure you found all the bombs'. Batman had known it was a risky call, that maybe you should have split up and split the difference, but he'd insisted you two stay on the same floor and sweep together. Too big a risk to lose each other in the chaos, otherwise. 'Buddy system' existed on missions for reasons.
The thing is, it was a big building, and it only takes missing one bomb.
It was all a bit of a blur, really. The sound of the explosion, the feel of the building practically quivering, then that first horrible crack. Bruce had taken plenty of falls in his life, but you never 'get used' to the feeling of the floor just crumbling out from under you. Instinct kicked in and for a while there was no 'thinking', just trying to mitigate the fall.
He supposes he's come out pretty lucky. He's on what feels like relatively solid ground again, nothing huge has crashed down on his head, and while he can tell he'll certainly be feeling this tomorrow, everything important seems intact. He coughs in the dust-heavy air, fumbling for his rebreather in his utility belt, squinting to try and clear his vision until he could get at night vision goggles next.
Batman is mission-minded as a rule, and this just turned from an evac to a search and rescue very quickly. But before he can even think about that, he's got a higher priority. "ty? ty, can you hear me?" He'll try his comm first, before starting to shout. He can still hear distant crumbling; more could cave in any minute. You'd been on the same floor - hopefully you'd both landed in near enough the same place. He's trying to stay mission-minded - and not panic just yet.
"ty, come in. Can you read me? Where are you?"
