"I was." He didn't believe in lying to children. They were smart, or they were supposed to if you brought them up right. Even the twins were very smart, even if destructive.
"Your dad and I wanted to be together, and we didn't think people would like that I was his boss, because they would think that I treated him better, even if I always treat everyone equally." That was a small white lie, because he'd treated Cass differently from the start, but not when it came to work.
He chuckled. "I ask myself that question all the times." He looked at Cass, smiling, and then back to Aiden. "It's because your dad cares too much and wants to protect everyone, which means he goes after the really bad wizards, the worse. We're all trying to get to them, but we haven't been able to get to them, even though your dad got really closed to doing it." Cutting of Lestrange's arm meant Cass had gotten closer than anyone else.
