Charles called for a House Elf and asked for a proper tea to be set up, before answering Pansy. "I wouldn't know, or try to hazard a guess as to what goes on in the minds of madmen," he said easily, not rising to the bait. The Elf served the tea quietly, and then disappeared without a sound. Charles had trained his elves very well.

"I have not seen much improvement over the past two years. Perhaps the status quo needed to be realigned, and there are times when that can only happen in the face of chaos." Charles had very defined plans for the near future, which included directing his wild dogs in very certain directions. He'd let them have their fun with the Weasleys, and by allowing Lucius to marry the girl. Now, added to his arranging for them to escape Azkaban, they were very much in his debt and under his control.
