WARNING: If you don't want to know what happens in this episode, don't read this photo recap!
The gang is hot on Murphy's trail as Sun Mei tracks his hijacked military vehicle (which Hector affectionately calls the 'Murphy Mobile'), though Murphy's since ditched the transponder in the belly of a Z. Gross.
Luckily, the gang finds an unlikely ally in the form of Barney Becker, a former postal worker who still drives around in a mail truck and hides out in the local post office. He seems lonely (he's been slowly going through everyone's unopened and undelivered Christmas cards) but harmless enough …
Sun Mei tries to contact her lab via the two-way radio at the local motor pool, but all she's able to pick up is a piece of melancholy music. This is apparently a code to say that her mission has been aborted and her reinforcements are all dead.
Everyone meets up again at the post office, where Roberta takes Barney's gun and Sun Mei takes a blood sample. Barney hasn't been bitten and there's nothing unique about his blood, so why the heck does he have this Z entourage? Barney is offended at being poked and prodded and tells them to leave town as soon as he gives them food and supplies, to which Roberta agrees.
Sun Mei stays in the main office to do more blood tests as Barney leads everyone else to the basement, where there's supposedly a fully stocked civil defense emergency shelter for the entire county. What's actually down there are the bodies of several postal workers …
Barney takes Sun Mei at gunpoint to his personal workshop, an abattoir filled with the remains of the unfortunate passers-by he feeds to his zombie horde. Barney had grown tired of 17 long years as a mailman, never getting his own greeting cards or love letters but instead being hated as the guy who's late with delivering a paycheck or unwanted catalog. On Day 1 of the zombie apocalypse, Barney went completely postal and killed his co-workers … and every single person in town. Since he was the last thing they all saw before turning Z, they've now got something of a fixation.
Meanwhile, Team Murphy is stuck in traffic, which in the zombie apocalypse means there's a vehicle blocking an already impossibly narrow roadway. It's a young couple whose little girl is dying, so Murphy, genuinely moved, offers to help and gives her a Murphy bite.
Murphy's lounging about on his throne when Dr. Merch says he has visitors: the young couple whose little girl he bit. The parents thank Murphy for not only curing their daughter but for making her not afraid anymore.
Later, Citizen Z is shocked to see that he's been given by far the largest portion at dinner. Kaya, her Nana and her Uncle Kaskae are actually starving, and their already meager food supply is quickly dwindling.
