There are just two episodes left of The CW's Hart of Dixie fourth season but the drama certainly isn't slowing down.

It's a moment fans have been waiting for but now that it's here, Zoe Hart has to deal with it; her best friend Lavon has officially hooked up with and started dating her arch nemesis Lemon. The two have been on the outs since Zoe landed in Bluebell. And while they have had their few moments of peace, they make it clear in the sneak peek that they are still not fans of one another.

Zoe says of Lemon, "That woman drives me insane" and Lemon says Zoe is "maddening."

Still, Lemon and Lavon continue their spark that began years ago. Lavon even reveals to Zoe that he had a "big night" before Lemon enters from a back room.

Zoe (played by Rachel Bilson) couldn't help but scream.

Lemon sarcastically responds, "Try to contain your enthusiasm."

What Zoe does try to do is be a supportive friend. But it's pretty hard for her to hide her dismay.

"That is so great!" she screams with a fake smile.

Lemon and Lavon definitely have history so it only makes sense for the on-again-off-again couple to come full circle toward the end of the season. As for Zoe, she's sporting her baby bump big time (Bilson was actually pregnant while filming) as Wade tries to encourage her to be nice to Lemon.

See the preview below.

Hart of Dixie airs Fridays at 8/7c on The CW.
