Oddly enough, the suit Tony'd been working on saved Steve from having to experience what it would be like to have the bond ripped away. That doesn't mean that Tony's in good shape, but he's not dead. The bond is weak for a moment and then strengthens as Tony finds his consciousness again, rolling his eyes upwards to figure out where he is before another missile hits his home and it shudders again.

"I just had the floors waxed," he groans and uses the chest and the gauntlet pieces of the suit connect with his own reactor to power the repulsors and send the debris -- one of his Bentlys, go figure -- out through what use to be the side of his garage.

By the time Steve can get to him, the way is blocked and Tony himself is scrambling to find a bottom half to one of the suits. The couplings won't be perfect. He's not even sure it will fly. But at least he won't have to leave Steve alone.

"JARVIS, where's my fucking Sentinel at? Tell me he's sleeping, lazy bastard!" He means well. Tony is a bastard when he's scared.
