Leander Prewett

Today at Hogwarts they started a new club, the Fighting or Dueling Club, with teachers supervising and awarding points to those who won and maintained a winning streak. You won every random match and challenge they gave you, maintaining your number one ranking, which brought you more attention. This annoying attention came from Leander Prewett, who sought you out at every opportunity to challenge you to a duel or at least ask for your help in his two-on-two competitions against Sebastian, and today was no exception.
You have to help me, imagine, the two of us teaching that show-off Sallow a lesson, we'll be the best!
