Alastor was held up in the hotel, watching the regular patrons go about their evening.

His hair was soaked, as was his clothing, and he looked to be fairly shaken-up by Hell's rain.
"C-Can I stay here?" He asks to no one in particular. Charlie, ever so helpfully bounced up to him, handing him a key. "Of course you can! Here, Alastor will show you to your room!"
