Episode 6 will follow in the wake of "Zombaby!," and the duo of episodes will herald a return to Pie Girl and Murphy's storyline.

"Well, you know, [Murphy] and Pie Girl had some fun last season and we'll see the ramifications of that and the complications that brings," executive producer Karl Schaefer told EnStars. "There's a couple of great episodes coming up where we'll see what happens with the result of the tryst Murphy had with Pie Girl."

Sketchy and Skeezy, meanwhile, will have a little fun with 10k in episode 7.

"Well, I will tell you that Sketchy and Skeezy will be back," Schaefer told TV Geek Talk. "We have a great Mississippi River episode that they're featured in with 10K, kind of a whole Huckleberry Finn thing that we're doing."

Catch up with the post-apocalyptic drama when Z Nation returns to Syfy on Sept. 11. See a preview for the premiere below.
