[Gosh, he really wants to dump his whole head under some water right now. That might help get all the pixie dust off him and stop his constant sneezing. Which he most ungracefully sneezes about three more times in quick succession before he nods to her.]

[So he's going to go up to the barn door again! But not just flinging the door open to expose themselves to the danger again. Instead, he knocks politely like it's someone's house. He probably looks a little silly with his hair all wild and his nose red.]

Ahh... Excuse me? Pixies-san? [Knock knock.] I want to apologize for stepping on your home! It was an accident! If there's anything we can do to make up for it, we'll do it! ... T-that's a promise as a hero!
