"Not a problem," Mason waved his wand slowly over her robes, sucking the shrivelfig juice from the fabric easily enough. "There we go, all set."

Herbology was messy and fun, it was supposed to be hands-on and practical, there was no avoiding the inevitable smears of dirt and plant extracts.

Mason then checked his pocket watch, pleased to see Phil hadn't nicked it yet. Gus' new niffler was going to be a pesky little miscreant, Mason just knew it. "I'll clean this up, I don't want you running behind to your next class. Nice work today Miss Potts." It had gone a little askew at the end, but had been been an improvement from the time before that. A little more practice and she would be able to do it in her sleep. 'I'll see you in class tomorrow."
