In a stunning display of maturity and ladylikeness, Katie stuck her tongue out at him when he pretty much said I told you so. It seemed like a good way to react to that comment, even if it didn't exactly answer the question he had just asked her at the tail end of it.
"I don't know, Davies," she teased him, "I think I kind of like making you work for it." She winked at him, then, obviously much more relaxed than she normally would have been around him, because she would not have normally been willing to tease him so freely.
It wasn't completely untrue, though. Katie definitely enjoyed watching him squirm and she wasn't likely to make things any easier on him in the future, especially once she'd sobered up completely. Where was the fun if she made it easy? No, she was pretty sure that Roger Davies was used to getting his way and while she would never admit it to anyone else ever, he was kind of good at this whole wooing thing. She certainly wouldn't want to take away his incentive to continue doing it.
