"Again, it would be hard to find someone who isn't a friend in the department, and I certainly wouldn't want an enemy to conduct the investigation." Percy sighed, knowing that McLaggen was right. "Cass let Lestrange blackmail him. I don't know what kind of information he passed on. I felt it was best if I didn't ask. I really do not know."
He played with the arm rest for a few moments and then looked up. "Cass's mother is a Muggle. Lestrange found out and kidnapped her. If that weren't enough, he found out that... that Cass and I aren't just friends. It started innocently enough. Cass was at my house because there was no one else to watch him day and night. It was the last time he got injured. It became more."
Percy sighed. "He wasn't thinking. No one could have known about us, but no one thinks clearly when your mother has been kidnapped, but that's irrelevant at this point. I've never treated him differently, but that's something for you to determine. You'll also have to determine whether the relationship itself is something you want to include in that report of yours. I will release a statement once Cass resign announcing our relationship. That should avoid any power Lestrange has. It will also stop Umbridge from getting me replaced. However should news of my involvement with Cass prior to his resignation become public... you understand that it'd be the perfect opportunity for that woman to appoint someone who would do everything she says. It would destroy everything Tiberius worked for." He stared at McLaggen. "I'm not saying this to push you or blackmail you in any way, but I need you to consider all the implication when you make your choices."
