This is going to be Lily's the first year in Hogwarts. Her big brother is a seeker and Albus is the first Slytherin in the family. With those two being already interesting enough, she feels like she has to be unique in her new school like them (to keep up with the family's name). But something unexpected happens and she wishes to be unique no more. In fact, she's thankful she's not in the hybrid student place.
