How do I restore Inee to sanity?

I'm just blundering around the Gateway Inn looking for loot a ghost. After having a chat with Inee I open a door and whaddya know, a ghost starts wailing on me. After dispatching it I notice something is still attacking me, and it looks like Inee has gone crazy, punching my glass armor with bare hands. I've tried a few different spells to calm him down, but no luck. I could just leave, but is it possible to bring Inee back to sanity?
