"Weeping electric blue polka dots aren't a good look for you. The lancinations badly clash with your hair."

"I wasn't supposed to be—"

"Taking out an entire hive of pixies on your own?"

"Yeah. Fuck but these hurt. Please help me? I could pay you."

"You could do a great many things for me, I'd imagine."

"Have you?"

"Imagined? Yes, Weasley, I have. Now strip off. I need to assess . . . your condition."
