Tessa wasn't the only one none-too-pleased to discover George making out with some hot young thing in New York right before Thanksgiving. There was also Dallas.

But will Dallas do anything about it? Will George? There's no denying something strange and lovely has been building between Tessa's goofy architect dad and Chatswin's hippest haute couture-wearing mom. And the sparks are really gonna fly over the holidays — where else? — under the mistletoe, during Suburgatory's fall finale (Wednesday at 8:30/7:30c on ABC).

Series boss Emily Kapnek tells that there are good reasons why these opposites attract. "You could say that George may have been drawn to more cynical New York girls in the past, but I think there's something very contagious about Dallas' spirit and how sunny and happy she is, as well as being very invested in her kid, which makes her appealing to a single dad like George in a way that he probably never would have anticipated," Kapnek says.

In this week's episode, "The Nutcracker," Tessa (Jane Levy) overhears George (Jeremy Sisto) breaking up with his girlfriend, Zoe, blames herself, and decides to get them back together. Little does she know, he's decided he's had it with "crazy city women" and wants to look for love in the 'burbs. At the same time, there's a lot standing in the way of an Altman-Royce romance. George is initially distracted by both his ex and Tessa's adorable art teacher Aimee, and then there's the not-so-little matter of Dallas' husband Steven (Jay Mohr), who is a mostly absent but completely decent guy.

"Marrying a man who's very successful financially and can provide this lifestyle she wants probably at one point seemed like all Dallas wanted," Kapnek says. "But in watching George, who is such a great dad, and how hands-on he is with Tessa, I think she's starting to see there are different kinds of men out there, and the value of having a partner who's really a partner."

It looks as though Dallas, riding high on the holiday spirit, is about to do something about it — whether George is ready or not. "George does pick up on her feelings," Kapnek reveals. "It's going to put a strain on their relationship and friendship at first, but I think it will be really satisfying to watch how it plays out. They both have conflicted feelings at different times, and watching them navigate this area is going to be really fun."
