"Your sister, unlike you, is wonderful. My father was the cause of ruining her first year at Hogwarts, causing trauma that will be with her for her whole life, and she was still capable of giving me another chance that I most certainly did not deserve. I don’t take things like this lightly. I was a right prick to everyone, I fully admit that. I regret the way that I acted, but it kept more people safe in the end than those were harmed, so I would do it all again in a heartbeat.
