Chocolate Cake- Bonding?

Stiles is eleven and Jackson is a jerk. Stiles holds Scott as Scott cries. He mentally swears to make Jackson's life as horrible as possible. A second year boy appears with a glass of water and a piece of chocolate cake. He sets them down without a word and turns to go but Stiles croaks out a, "Thank You." Chocolate cakes are great for bonding (Hogwarts AU)
