Levi can bitch at him for his choices when he's regained his form again - for now, he'll just have to make do with his efforts. The door is indeed open, and Erwin hums a little sweeping up fluff and feathers. He sneezes once himself -- and turns when he hears an echoing, but much cuter version of a sneeze coming from the doorway.

"Bless you," he says cordially, perhaps a little too tickled at himself for saying it to Levi in critter form. Circumstance aside, it's jut a little too absurd to not be a little amused about it.

"I wonder what you're meant to be," Erwin wonders aloud, and only just stops himself from voicing his next thought - Hange would know, or at least would be wasting no time to figure out. Perhaps they can do that next. "Some sort of weasel, perhaps? Why this creature, do you think?"

Of course, he knows Levi can't really answer him. That doesn't mean he should stop trying to make a conversation - perhaps it'll prove to be a nice distraction.

He carries on with the cleaning, gathering the fluff and feathers by the handful to shove into the bag when it proves easier than trying to keep it in the pan and dump into the bag. More manageable piles are swept and bagged, and when he's about done, Erwin turns back to Levi.

"How am I doing, Levi?"
