Dislocated shoulder. John deduced before Donnie mentioned anything. Cracked ribs. Bruising. Someone had really done a number on Donnie, and this was only what he could see. He couldn't tell if he was delirious from a possible concussion or if he was really really drunk, but both seemed the most likely. Unfortunately, the easiest way to fix a dislocated shoulder was....
“This is going to hurt like a bitch, Donnie.” John warned, before moving the dislocated shoulder back into the socket and, with some force, popping it back in. His hands moved down Donnie's chest, feeling for the cracked bones. Usually he'd get an x-ray or something so he could see what he was working with, but he wasn't in his office, so he would just have to make due with what he could feel. There were three cracked ribs on the left side he could tell. He had to handle Donnie much more than he would a usual patient, and with less to relieve the pain.
He managed to repair the ribs, though, and the bruising. He went about focusing on the concussion after that. He would usually tell him to take a few pills for the headache, but he didn't want to mix pills with alcohol, so instead he did an array of tests, checking his hearing, vision, and reflexes. Donnie was lucky. He probably still ought to go to a real hospital, but he knew that Donnie wouldn't go, that's why he came to him. With most of the physical injuries dealt with, Donnie just needed to sober up and rest his head. There wasn't much he could do for a concussion, but Donnie definitely had one. Not apparating had been a brilliant idea.
“You're gonna crash here tonight, Don.” He said to him. “But first, you're going to need a shower and a few glasses of water—actually, I think I have a sports drink, that should be better for you. Give you those electrolytes too.” He bit his lip, still worried. He went to grab the light blue beverage, and brought it back to him. “So, physically, anything hurt? Any ribs I missed? Anything?” Donnie looked fine now, but John worried. “And emotionally, well, something's definitely eating you. Go on, Donnie. Out with it.”
