Hermione rolled her eyes, not bothering to hide her reaction. She didn't doubt that Malfoy was trying to goad something out of her — though what exactly, she wasn't sure. He'd been mystifying her a lot as of late, his intentions never quite clear, though he also never carried quite the same level of disdain around her as he had in their early school years.

She nudged Malfoy's cup of tea forward, then narrowed her eyes in thought. "Potions was the first subject which came to mind. And if you're afraid of having lost your touch, I can certainly help to test your skills. I've been practicing for all this time, after all. I could even teach you some of the latest potions that have been devised in the past few years." Her lips curved into a grin.
