"So . . ." Dorian scratches the back of his neck. He glances down. Then he glances back up again. "Do both of these need a happy memory?"

He begins to think it was a mistake. Train in the use of his shard: yes, it seemed like a good idea. It seemed useful to know how to activate it, if he had it in there. To have that strength and agility to support him, to be less hindered, less limited by humanity. And when Hermione also suggested some of his magical training, it did not seem strange to add that in as well. But now that he is here, before her, faced with the prospect of performing these feats . . .

Let's just say Dorian Gray hasn't had performance anxiety in a long time, but the day has come.
