Albus Potter never asked to be a wizard. He never asked to be the son of Hogwarts prodigy Harry Potter. He never asked to follow in his brother James' footsteps. In fact, he never wanted any of it. He was alone and isolated, with no one to really talk to except Hermione and Ron's daughter, Rose, but she always made him feel stupid anyway. He gets whisked into the magical world of Hogwarts, and finds out he really is no good at Magic. He messes everything up. When a certain stone goes missing, everyone points their fingers at him.
