Insurance firm manager Blair and her receptionist Gina attempt to flee Atlanta at the start of the walker plague, only to find themselves caught in a time loop that keeps ending with their deaths.
Chekhov's Gun: Gina's scarf and lighter are used in the final loop to ignite the tanker's fuel and burn up a walker horde.
Face Death with Dignity: In one loop, Blair's reaction to seeing she's cornered by walkers is to bare her neck and tell them to "get it over with".
"Groundhog Day" Loop: The episode is built around Gina and Blair reliving the same few hours over and over again.
In Spite of a Nail: Even in the final loop, Gina and Blair's best cooperative efforts fail to save the woman in the gas station parking lot from being eaten by her infected husband.
Out-of-Genre Experience: Aside from being a franchise about a Zombie Apocalypse, the Walking Dead universe has always been mostly grounded in reality, without any supernatural elements (even the walkers being the result of a virus rather than any kind of magic). By contrast, this episode features a "Groundhog Day" Loop for no apparent reason.
"The Reason You Suck" Speech: After numerous loops leave her slightly unhinged, Gina gives Blair a rambling speech about what a Bad Boss she is.
While Blair insists that she and her boyfriend are only going on vacation, it's clear that they're trying to escape the slowly unfolding chaos in Atlanta.
The DHS agent, by contrast, outright admits to trying to escape the city before the military puts it under total lockdown.
In at least one loop, the tanker driver takes advantage of Blair and Gina's arguing to jump back in his truck and drive away.
Shotguns Are Just Better: Gina keeps her mentally unwell brother's shotgun in her trunk to keep it away from him, and puts it to use trying to hijack the gas tanker.
