"You do understand that it's not an answer, right?" Peter asked, because he wouldn't put it past Sirius to think that he had answered. "And before you say anything, let me who you. I'm doing okay, because Cassandra and I hadn't known each other that long but I'm also angry that she died so young, and I'm angry for her, because she should have enjoyed life, but I'm also angry for me, because she got me. Despite the fact that she was born in the 19th century, she understood me, and I thought I'd never have that, because I'm awful with women, but I was fine with her. I could just talk to her."
He took a deep breath when he was done. He hadn't meant to say all of that, but Sirius needed to hear it. He needed to know that he wasn't the only one with fears and insecurities. "Now you're turn, and don't give me the diplomatic answer. It's really beneath you. You're happy he's happy. Well, yeah, I believe that, but that doesn't answer how you feel about the fact that he's dating your brother."
