If you're on PC you can try to enable/disable him. Otherwise I'd just wait for time to pass, hopefully he'll show up at your home soon enough, or maybe he may appear back at Jorrvaskr. As far as console, you're kind of at the mercy of waiting, doing something to get his attention like attacking and calming etc, and saving/reloading. Sometimes if you push NPC's it helps them snap out of minor issues, just sprint at and run into them. That's assuming, of course, that you can still find him at the dragon roost where he was examining the dead lizard. Good luck.
