He'd gotten his broom and walked out of the manor and passed them, over hearing them, but didn't say anything, sick of hearing how bad a father he was and how he was never there for Cody, when he was, cared about him but he was so stuborn, not listening to him, then whining when he was in trouble, then blaming it on Remus, saying it was because he didn't love him, it was like a broken record, sick of it, he just decided to let them get on with it.. learn from his own mistakes.
