"Hey there, Bambi! I thought I'd drop in. You don't mind, right? " He invited himself in regardless, walking past him with a rather smug grin plastered on his face. "Ha, of course not! Anyway, there's actually something I wanted to talk to you about."
"I think your manners need a little bit of work, your majesty, I never invited you in"
He grimaces at seeing the short man invade his space so casually and without a care. That grin really irritated him. Alastor was seething and not wanting to see anyone right now, hence the closed door.
"Perhaps we could discuss whatever it is you require of me later"
Alastor was already in pain for the night and trying to rest while no one was paying attention.
