She goes to Lockhart’s class

The sunlight creeping across her curtains reminds Hermione of her daily responsibilities. With a sigh, she gets up and changes into something less stained and heads down to breakfast to join Ron and Harry. She’s already late, so she eats quickly and the trio dash to their first class of the day: Defense Against the Dark Arts.

Ron and Harry grumble about the new teacher incessantly, even when the man himself proudly steps through the doorway and introduces himself. “Greetings! I am your new Defense Against the Dark Arts teacher, though you may know me already by my published works.” He winks at the students, “My name is Gilderoy Lockhart!” Hermione has already had enough of this pompous douche and his bullshit books. Regardless of her interests (and indeed, most of the class’), Gilderoy continues his self-aggrandizing introduction.
