Hmm. So it turned out that stuff people are allergic to were not part of the potion. That had been Ari's guess, so this time the girl was actually pleased at her reluctance to raise her hand and answer the question, because had she done so, she would've been wrong, obviously.

The theoretical part of the class was soon over, and they were starting the potion now. By filling their cauldrons with water, simple as that. So far so good. 'Aguamenti.' Ariadne spoke firmly, pointing her wand to the inside of her cauldron and watching it fill with water, until she gauged it had reached the right level, when she stopped the charm. Like the rest of the class, Ari was now waiting for instructions, still feeling shivers down her spine when Lafay walked by her, though not as much as when she had been a firstie.
