Coop knows who Charlotte is, of course he does, he's seen her around town since she's moved back and normally, he'd have gone right up to her for a good old-fashioned flirting session but there's got to be some kind of bro code that prevents him from doing that with a friend's younger sister--especially a friend that he'd spent a lot of time also flirting with in the past. But Joel has become a much closer, much more trustworthy friend to him over the course of the past few months, and Coop's found that he's weirdly willing to do a hell of a lot to make sure Joel and Spencer are okay, that they're safe and have help when they need it, because they're good people. It means something, to know that good people give a shit about him, too.

Of course, that doesn't mean that he can't flirt now that she's approached him, right? Totally different.

"Oh, it's definitely that kind of Christmas party," he answers with a grin, holding the bottle a little higher up and out toward her. "It can be now, at least. Eight or nnine shots of this, and we could be dueting along with these Christmas songs in no time."
