"This isn't all that late for me anymore," William confessed, smiling faintly. "Between research and private study, I'm afraid I've been using up more than my share of the school's candles."
He ran a quick eye over the plants surrounding the closest bench before he sat, cataloging them to make sure it was safe to sit. There was a thin demidryad sapling in a pot next to him, so he stretched out one hand to let it investigate his skin, to wind interestedly around his pinkie finger. He understood plants full of curiosity.
The demidryad made a little cooing sound, tickling the webbing between his thumb and forefinger, and William cleared his throat, looking up at Spencer. "That's what I wanted to talk to you about, actually," he admitted. "I've been doing an independent study toward one of my NEWTs."
