OH COOL! So the antidote was the base potion itself!? It was like a lightbulb moment, and Zhenya was almost embarrassed that she didn't pick that up. It was just logical, was it not? Anyway, she wrote it down on her parchment, put HER two vials into her bag, protected in a side pocket, and packed away all her things, then hopped down with the vial of the potion to hand over. She gave it to Professor Culloden, said "See you Professor, thanks for another great lesson," and left. It had been a great lesson, but... really, all Potions lessons were great. Zhenya LOVED potions.
