Episode Recap: Zunami

Citizen Z is bored, and he might not be doing so well: shortly after an unidentified alarm goes off in the listening station, his vision goes fuzzy for a second, and he looks up to see there's a fireball from outer space hurtling toward Earth. Wait ... what? Yes, a Russian spaceship has landed in the station's backyard.

Meanwhile, things aren't going well in a small town in Nebraska. The team is having a hard time finding water and they're almost too dehydrated to run when the zombie horde starts closing in. They finally make it to shelter and are joined by some new survivors.

Back at the listening station, Citizen Z meets the pilot of the Russian spacecraft: Yuri, a seemingly good-natured cosmonaut. The new BFFs have some Earl Grey tea as Yuri describes how life was rough on his space station and how he fled on an escape pod. They break out the vodka and toast their survival, though some questions remain: Where are the rest of the cosmonauts from the space station? And why is Citizen Z's dog still sleeping?

Back in Nebraska, Murphy tries to rally the troops as one of the new survivors tells them that the zombie horde is migrating from Canada because they don't like the cold. Most of the zombies were part of a colony of survivors in Alberta who all turned within a week. It's sad stuff up there! Murphy wonders if the zombies have an actual leader as the team hears a scratching sound coming from the morgue. Doc and 10K take down a zombie and the team commences to climb into the body lockers to hide out.

Back up north, the new BFFs get a little tanked, play games and develop something of a fast-forward bromance. It's all very touching until Yuri calls his new friend 'Simon' instead of Citizen Z. Wait a minute ... how does Yuri know his real name?

In Nebraska, everyone climbs into the body storage units but by the time Roberta has secured everyone, the remaining unit is occupied by a zombie. As Roberta allows Murphy to seal her up in a body bag, she tells him that he has to return, as getting him to California is of vital importance.

Back up north, Citizen Z is getting very suspicious of his new pal. Is Yuri who he says he is? Is he a ghost? A … space zombie? Things get even weirder -- and more dangerous -- when Citizen Z gets out of the bathroom and finds Yuri wearing his space station suit. A big fight ensues and ends with Yuri tied to a chair. Yuri keeps asking Citizen Z what's wrong with his dog ... and, come to think of it, yes, what is wrong with the dog?

Citizen Z is now convinced that Yuri has poisoned both him and the dog. As he struggles to figure it all out -- assumingly with a splitting headache -- Yuri turns the tables and now has Citizen Z tied to the chair. The cosmonaut keeps asking, "What do you know?"

Meanwhile, in Nebraska, the new guy freaks out and climbs out of his hiding place in the morgue to get eaten and Murphy meets a family that has been hiding out from the zombie horde. Instead of helping them, he steals their food and water ... and lets the husband/father, now a zombie, back into the house to snack on them. The zombie messiah can be a cruel zombie messiah!

Back up north, Yuri asks Citizen Z what's different about today as Citizen Z continues to believe that both he and his dog have been poisoned. Just as Yuri begins choking Citizen Z, the truth is revealed: Yuri was a hallucination caused by Citizen Z's rapidly deteriorating mental state due to the lack of oxygen in the station ... the cause of the unidentified alarm in the first scene. Citizen Z drags his unconscious dog to the main doors as the cool air revitalizes them. So much for having a new friend!

Back in Nebraska, the horde is heading for the next town as Murphy returns to the morgue with the food and water, using his zombie-messiah powers to draw a zombie's attention away from Roberta hiding out in the body bag. The team has a family meal on a table usually reserved for dead bodies while Murphy realizes he may be changing even faster than he thought.
