Okay, y'all, that was about as close to visual id!fic as it's possible to get, wasn't it?
I may have written a fic in which someone falls off a cliff and Steve rock-climbs them to safety. But even I never contemplated Steve splinting his own arm (heck, I bet he'd re-inflate his own lung if he had to, and had the supplies to do so right there in that awesome pack of his) and then hauling himself up one-handed.
If I ever claw my way out of the id vortex, I'd be happy to have a discussion about the technicalities of top-roping (and why "Danny, pull up the slack" isn't the safest way to go about things), but I may be down here a while.
