Terrence could understand the concept of her disgust, but she wouldn't be around to make a mark in his relationship with Kat, so he really didn't care. His girlfriend, with perhaps the exception of her job, was practically tailor-made for him.
"Muggle hunting," Terrence said, half-distracted as he dragged her through the halls. "The good ol' days, you know. But you wouldn't, would you? Blood traitors..." But there was no real venom in the propaganda, just rhetoric that he knew he should spout. Not that he had a problem with muggle hutning. Personally, it would probably be fun.
"Make yourself at home, lovey," Terrence told her after he pushed her into the cell. There was no way out and it was well-warded, and now that he had them here he was going to hire a bit of muscle to keep watch just in case she was more clever than she looked. "You're going to be here for awhile, until I can figure out what else to do with you."
