Setting: 8th year, after the war
Disclaimer: I don't own HP, but I did make up the Cupiditatem.
Hermione Granger was in a very big rush. She was on her way to Double Potions with the Slytherins and the rest of the Griffyndors, but was slightly off schedule. She ran past the other students in the hall, outsmarted the staircases, and reached the dungeons just in time. She hurried into class and sat down in her seat, beginning to take out her materials for the class. Before we get on with the story, I need to explain Hermione's week so far.
It was the first week back at Hogwarts. Hermione had be renamed Head Girl, and Draco Malfoy as Head Boy. This year though, they were expected to share a dorm. Hermione would have been mostly fine with this, annoyed at most, had it not been for Draco's strange behavior. Hermione caught him staring intensely at her MANY times, and he hadn't insulted her once this term yet! Furthermore, she seemed to see him in the hallways much more often than she should, considering their schedules. And in classes, her always sat behind her or next to her. It might not sound that strange, but for Hermione, it was.
And so, that explanation brings us back to Potions Class. Oh look, they've already started it. Hermione is eagerly taking notes, while Draco Malfoy, sitting behind her, is drawing a very accurate portrait of her. Let's go take a look at his world. He can be heard mumbling under his breath, phrases like "She's a challenge, but I will have her..." while drawing her. Okay, that's a little creepy. Why don't we see what is going on in class right now?
Professor Slughorn is teaching about two very interesting potions today, Amortentia and Cupiditatem. We'll learn more about them in a second.
