Matthew made a small noise of disgust as Stephen flogged his idea of psychoanalysis to death. "Really, Stephen? I'm sorry to bring this up, but you are a Mu-ggleborn!" He only narrowly caught himself before he'd called Stephen, his last friend in the world, a Mudblood! "What would you know about what wizarding society was like almost fifty years ago, when my parents were wed?"
He made an even more obvious noise of disgust at Stephen's assumption that he'd wanted power from the Dark Lord. "No, no, I didn't, Stephen. Honestly, I was NEVER interested in power! I was only interested in helping to make a better world for wizarding kind...! I mean, really now, Stephen, have you ever known me to be dominant or power-hungry?" But all the same, the little voice in his head sprang up again; it seemed to grow even louder the more inebriated he became, You do wish you had some dominance over your own sister -- to force her to come home with you, for example! Or even to take you into her bedroom...! Matthew moaned softly, and clutched his head in both hands, abandoning his wine goblet on the end-table.
