"Yes and no," Kate said quickly, "The trajectory of the relationship is the same, but it started way earlier in the books because this guy was living vicariously through his characters." She jerked a thumb in Castle's direction with the words. "He wanted to sleep with me, knew he wouldn't get that far, and just had Nikki and Rook sleep together instead." Which had gone from embarrassing to annoying to frustrating in the interim years before they had actually gotten together. "They break up a lot more than we do because they start dating so early on and there's some.....other things...that happen in the books that didn't happen. Or at least didn't happen to the character they affect in the book."
Kate didn't say that it was her shooting, it was another part of her history that she hadn't explained to Lucifer, but it was still on her mind and the reason why she briefing pressed her hand to the knot of scar tissue between her breasts that was always hidden by her clothing in public. "Patterson's a sore subject for Rick," she explained, thankful to move on from the shadowy places of her life, "And an easy way for me to tease him."
At the mention of Battlestar Galactica Kate laughed outright, quickly covering her mouth with her hand as one of the store attendants looked over in her direction in surprise. "Okay, no," she interrupted once she'd gotten a handle on herself, turning towards Castle, "If you're going to dress up as a sci-fi character it's gonna be the Captain from Firefly. You look like that guy anyway. Or Batman!"
