Situations arise and I need to present around the castle. As for Mr. Weasley, I don’t see him being dependable or mature enough for this task. I’m already asking a lot of Mr. Nott to agree to room with a former Death Eater. I also can’t be certain that he wouldn’t cover for Mr. Malfoy. You, on the other hand, are responsible enough to administer the potion. The Ministry also thought that you might enjoy being the one to do so."
