Violet sat back, pleased to have finally been able to give someone the potion she had worked so hard on. Really, she was rather proud of her strengthening solutions. She had made it early in the term, when she was still a free girl, and had planned to give it to Professor Schmoe when he was looking so poorly after the Opening Feast. But then she'd gone and shown it to Professor Varma, just to make sure it was really all right, and the professor had told her there were rules about giving people potions without going through the healer, etc., etc., etc. Well, Violet was done with rules and asking permission, so she'd put it in her pocket and planned to give it to the first person she thought needed it. Of course, she'd expected that person to be herself, and she was a bit disappointed not to have it anymore in case she needed it later. But Williamson needed it now, so she figured she'd better give it to him while the giving was good. Before someone found it and took it away from her, like they'd taken her wand.
