I just spoke with the people at the Forever Wild Animal Rehabilitation Center, and it seems that Smokey is doing OK. They think that he hurt himself by flying into a window or something, and the injurty is to his right eye, not his shoulder as I had thought. He was groggy and shocky when they got him on Sunday morning, but apparently he's perking up and on the road (fingers crossed) to recovery.
They even said they'd call us when he's ready to be released, and he'll come back to where he was found. So, his little mate will (hopefully) soon have him back!
