WARNING: If you don't want to know what happened in this episode, don't read this photo recap! 

So. The team has found their way to Chicago, the Windy City. Although, what happened was that with all the chemicals that have been used to try and stop the zombie apocalypse, Lake Michigan has basically covered the place in a thick green foam.

When Doc and Murphy make their way into a Barber shop to rest, they bump into Sketchy and Skeezy. Remember them? The con men from Season 2? They're back!

Sketchy and Skeezy try to warn Murphy and Doc about…something. The barber in this joint sure does seem to want to kill them. And it turns out…

There's a sniper upstairs! And zombies in the basement. So the whole thing is definitely a set up. But to what end?!

Eventually, Doc figures out that the barber is actually a con man he knew back in the day. A guy who robbed Doc and even stole his underwear. This whole thing isn't just a set up — it's a robbery!

And even though our team has gotten out of way worse scrapes than this, not even 10k or Sarge seem to be able to help them. They arrive and are now also part of this whole strange robbery.

Meanwhile, Roberta continues to find her way through the green foam in Chicago and begins following someone who seems to be either escaping or beckoning her.

After some misadventures including an overly tan zombie, the team realizes that Sketchy and Skeezy seem to be trying to swindle THEM out of something. And while they try to figure out what to do about it...

A new pair of robbers show up! Also from a past season. The guys that Skeezy and Sketchy swindled by biting! Remember them? There's a quick dudes-kissing-other-dudes joke, and Skeezy is sent back out into the world.

Ultimately, the gang trick all of the bad guys into opening the trap door full of Z's in the basement downstairs. This leads to the downfall of both the new bad guys, and the old bad guys.

Turns out, the whole thing was set up for Skeezy and Sketchy's retirement. They're going to run a barbershop in Chicago!

Back outside, Roberta finds Dr. Teller! Who turns out to be alive! He takes off his mask, hands Roberta some canisters and tells her that everything depends on her.

Finally, Operation Bitemark heads out of Chicago, on the way to their next adventure.
