Z Nation has already received a third season, but that doesn't make the season 2 finale title any less worrisome.

'Z Nation' Season 2: The Zeros Have A Dangerous New Ally, A Season 1 Villain Set To Return

Operation Bitmark ended its freshman run on the brink of a nuclear apocalypse. This year, the Syfy series will close out its 15-episode season with the equally ominous "All Good Things Must Come to an End."

Thanks to last week's renewal announcement, we all know that the "good thing" won't be the blood-spattered hilarity of Z Nation. That being said, any ending that doesn't involve a ZN1 cure is bound to be devastating. With Dr. Kurian's return scheduled for episode 12, things are looking bleak for Murphy and Co.
