Dis raised her eyebrow and chocked back a scoff, making it sound more like a sneeze than anything else. Then, a question occured to her, as she was walking out of the classroom, she stopped to ask the professor, "Excuse me, Professor. I wanted to ask, what's the purpose of the potion?" Dis shook her head and waved her hand. "Let me rephrase that. Why use a summoning potion when you can just use Accio? It works just the same without the hassle of having to brew a potion and then consuming something that is ultimately poisonous. Accio can summon nearly anything, from anywhere, except those things with certain protective spells on them. So, what I'm asking is, what is the point of the potion?"

DIs was truely interested in the reasoning behind such a potion and wanted to hear what the foreign professor had to say.
