Life in Bluebell, Alabama is about to get a lot more interesting.

On tomorrow night's new episode of Hart of Dixie, Lavon will wonder why Didi is acting so strange, eventually sticking Zoe on the case. And what will the doctor discover? A certain piece of information regarding Lavon and Lemon. Scandalous!

What will she do about it? How soon until George learns about the affair? Answers await on "Aliens & Aliases." But you can get your first look at what's to come in this preview:

Elsewhere, look for Wade to ask an unusual favor of Lemon in order to pull one over on Joelle's ex, while George goes to Zoe for medical advice regarding a client.
