I love how foolishly and confident you've written her, the way that she's the only one who thinks things are as they should be (even though she doesn't really; I think she's not too fond of the Dark Lord herself, since he's grounding Draco and sending Antonin away all the time, and besides, he's creepy), the fact that her schoolgirl crush is the center of her universe. She's such a beam of optimism!
