Throughout The Walking Dead, putting a roof over their heads has been a key priority for the survivors. But whether it's the comfy confines of the CDC, a rolling farm, or a seemingly well-secured prison, a permanent home has proven elusive. Still, the characters press on in the hopes of finding a place that they can finally call (a walker-free) "home. "After getting yourself calmed down and addressing immediate life threats (an arterial bleed, say, or being in the path of a flash flood, or zombie attack), shelter is your top priority," says Holding. "Shelter – whether that's appropriate clothing, a debris lean-to, or even a prison–represents protection from exposure. Mainly environmental exposure, but also emotional exposure. Hyperthermia? Kills you in three hours or sooner. Psychological refuge? Priceless."
