The Fear the Walking Dead season 6 finale has totally changed the show for season 7 in terms of its post-apocalyptic setting. The actions of John Glover’s Teddy have shaken up Texas in a way that’s sure to be a game-changer, introducing a whole new danger for the characters to deal with.

The back half of Fear the Walking Dead season 6 has seen Morgan (Lennie James) and the others contend with Teddy, a serial killer and cult leader bent on destroying the world and starting anew. For years, he thought his vision was impossible to make real – until he discovered that he could gain access to the nuclear arsenal of a beached submarine. After acquiring the keys to the USS Pennsylvania, Teddy put his plan into motion. Morgan and Strand (Colman Domingo) stopped him before he could go as far as he had intended, but they couldn’t prevent the launch of 10 nuclear warheads. Much to the dismay of Morgan’s scattered group, they touched ground in the season 6 finale.

The destruction caused by the warheads was only briefly glimpsed in the episode’s final minutes. Only one main character – Zoe Colletti’s Dakota – died as a result of the detonations, but the characters aren’t out of the woods yet, and may not be for years to come. The nuclear radiation unleashed by Teddy may have just redefined Fear the Walking Dead’s world. Up until now, all three shows in The Walking Dead franchise share the same backdrop: a civilization thrust into chaos and ruin by the rise of zombies. The season 6 finale shows that Fear the Walking Dead season 7 will invoke a different post-apocalyptic setting, which is a landscape devastated by nuclear weapons. It’s a rather popular subgenre, as seen with the Fallout video games, The Terminator franchise, the Mad Max movies, Planet of the Apes, and more.

Usually, zombie apocalypses and nuclear holocausts are kept separate, but Fear the Walking Dead just found an exciting way to combine them into one. As co-showrunner Ian Goldberg put it, Teddy’s big move added a “new apocalypse on top of an existing apocalypse” [via Insider]. Goldberg also called what comes next a “reinvention”, and that hardly feels like an overstatement. After all, it makes sense that that throwing nuclear radiation into the mix (in a much more substantial way than what happened in season 5) will completely change the characters’ lives and how they survive going forward.

How big of an impact it will have was signified by Grace’s words to Morgan in the Fear the Walking Dead season 6 finale. Grace, an expert on the subject of nuclear radiation, said she’d rather die than live in a place where they’d probably become infected with radiation poisoning. Her fears are indicative of the trials to come. They and the rest of the group may have survived the initial blasts, but they have other threats to worry about in season 7, such as nuclear fallout and an untold number of irradiated zombies. Plus, there’s the matter of the physical destruction it wrought on the buildings, and all the casualties that the surrounding areas must have suffered. All things considered, nothing may be the same again.
