It’s early morning in the Gryffindor common room. Hermione is absorbed in a book by the fireplace. Nearby, an older student casually tosses a Quaffle with friends. He’s relaxed, a stark contrast to Hermione’s focus, but their resemblance is clear.

You approach, and a friend introduces him. “This is Andy Granger, Hermione’s brother.” Andy flashes a warm smile, instantly making you feel at ease.
