"Really? I'd have thought it'd be past your bedtime." Barty walked closer, stopping a few feet away from the boy. He was very much still a boy, younger even than his years. Or perhaps that was just the standard Barty was going with, a standard by which Draco here very much fell into the category of 'pathetic'. "You should be asleep. Or, you know, studying. If your grades haven't improved a lot since I taught you."

It was fun, he thought. Reminding the boy of how he'd been his teacher. Especially because he punctuated the sentence by subtly moving his finger up and down, not unlike a certain bouncing ferret.
