"Well, it's a fine time for a stroll. Business is certainly booming," he points out. Small-talk with a royal should be harder than this perhaps, but Quirrel is already delighted they're not immediately running him off. Asking about him? The rumours were certainly true about their nature.

"I'm running errands, nothing particularly scintillating I'm afraid to say. We're shoring up some of the conveyance ducts and - well! I seem to be the only one who remembers the part codes by heart, so I thought I may as well be the courier as well."

He flicks up the invoice, pretending to double-check said part codes. He is actually side-eyeing their wings.

"There's no hurry back, though, and the truth is I wanted to stretch my legs." Quirrel sounds a little candid here. And bolder, encouraged by how casually they're receiving him. "Now seemed like a good time to say hello. Quirrel, of the Archives. Whether you were aware or not," because it would be understandable if he had slipped their notice, "you are now, for better or worse. An honour, of course!" He gives an accompanying cheerful dip of the head.
