"We used to be friends, once, before I came to a parting with Tom Riddle over his methods and means. Roddy tried to keep of the pretenses, but given the low quality of the minions they sent to bring me down after Tom's death, I don't think they've done at all well at the evil mastermind thing."
"Look at them," Antonin chuckled. "Roddy is shy a wing, and they are all on the run these days. His best henchmen are either that mad werewolf Grayback - I have a spot reserved for him in front of my fireplace in Dolohov - or his younger brother and his bitch, neither of whom is any great shakes as a scholar or a fighter. I wouldn't say they are doing too well; would you?"
"After the lawyers are done tying Umbridge in knots, I don't think she'll have any future as Minister at all." Antonin made a quick gesture as if throwing something small away. "It wouldn't be the best idea I could think of to hitch your cart to her star just now."
