He was steadying the longer they waited, but Tony had too much of a point. The smoke couldn't be good for anyone inhaling it and there was an unfortunate amount of the stuff to spare. He shifted when Pepper did, wincing at the movement and hissing despite himself. Reactions were hard to get over, and it wasn't like he went hurting himself on purpose so he could learn how not to react to pain. That would just be stupid.

"I'll heal," he said, automatic to Pepper's concern. It took a moment for him to catch up with himself and add: "Very soon. It's a power, whatever you want to call it. Check on each other."

That he even had the breath to say that now was speaking wonders. His back was still a bloody, burned mess but adrenaline was kicking in and wounds were closing left and right. He cast his attention about while mentally-convincing himself he was ready to stand. He could do it. Maybe... just a few more moments before he tried, though.
