Bellatrix, I thought she needed help, I wanted to help her. It was confusing. I'm well aware Nymphadora can be somewhat unhinged when it comes to — you weren't here when she was tortured, were you? She was a broken woman. Begged me to kill her, rather than lose herself to madness. I ran him through instead — but I thought he was a beast, I thought he was attacking her. It was all such a mess. I knew, I did, he never kept it to himself, but I'd never seen him in that form. Turned back when I killed him. Forgave me. The absolute idiot.
