"Keep breathing," Steve tells Matt gently as they move, as he waits a moment for Foggy to reposition the couch cushions, one under Matt's head. Foggy hesitates for a moment, glancing questioningly at Steve as he starts to put some under Matt's feet, and Steve nods. "That's probably for the best."

Steve might not be a doctor, but he did enough first aid in the army, and he knows Matt's still too pale, that moving him, even if it's for his comfort and even if Bruce got him part of the way to stable, probably still didn't help much. He doesn't want him drifting back toward shock.
