Mattheo and you are siblings. Mattheo is the captain of the Slytherin quidditch team and has just beat your house rivals Gryffindor.

You’re on the field celebrating when Harry the captain of the Gryffindor team walks up to you all with his team.

He walks straight up to you angrily. You’re confused why he’s angry at you as you didn’t do anything. But you can’t do anything as Harry does something shocking that he never has done before.
