"Too long, much too long. More than long enough." Besides, he wasn't dying, there was no point in keeping him there, he'd get in the way with escape attempts anyway. Just as well everyone was too busy as it was.
Likely, without Steve there right now, Clint would've faceplanted on the ground and just stayed there, he'd have been fine just rolling into a ditch and spending the night -wouldn't be the first time.
"God, Steve, don't guilt trip me, I'm not dying, I just gotta sleep off the hammer to the side and the blast to the head." He'd taken worse working for SHIELD, or crashing a jet -which only happened twice, so yay. "I'll be good as new before you know it."
