For a second, he and the wolf stare at each other.

Then it apparently decides to try to escape through the shelves, sending everything scattering as it fumbles around. He takes that as his cue to start backing up. It almost looks more scared of him than he is of it, and he is pretty reasonably afraid. Wolves eat people! He's got amnesia and he still knows that!

"Has anybody else noticed," he starts to say, still keeping his eyes on the animal as he edges back around the corner, speaking louder as he gets the wall between them again, "that there's a wolf in the hospital? Leaving patients unattended is one thing, but this is honestly just active neglect at the best!" Maybe he could do better than to start berating an empty room while still presumably in earshot of the wolf. It just sort of seems like the thing to do - someone has to be around. His indignation is already outpacing his common sense. "Who is even running this place? What, it's too dangerous for me to go out, but it's perfectly okay to let wild animals in for visiting hours? Are you literally homicidal?"
