"The Key" is the fourth episode of the sixth season of the post-apocalyptic horror television series Fear the Walking Dead, which aired on AMC on November 1, 2020, in the United States.
John writes letters to June in which he expresses his budding appreciation for their new camps, and his hopes that they can be reunited. Assigned to security, John is on patrol when he finds Cameron stuck in the fences, devoured by walkers.
Elsewhere, Morgan has recovered from his injury and is travelling with EmileâÂÂs bloodhound, Rufus.
Back to the camp, John investigates CameronâÂÂs death and finds an earring at the scene. John talks to CameronâÂÂs companion, Janis, but Janis denies the earring is hers. John then meets with Victoria and shows her the earring. Virginia asks him to keep things quiet so people wonâÂÂt be alarmed.
During Cameron's funeral, the Rangers catch Janis trying to escape the camp. Virginia searches Janisâ bag and produces the other earring. As John locks up Janis, Janis claims that Virginia is setting her up. John goes to Virginia, but Virginia tells him to drop any further investigation, adding threateningly that she has read all the correspondence between him and June.
At dusk, John exhumes Cameron's corpse. He discovers the broken piece of a knifeâÂÂs handle lodged in Cameron's hand. John reaches out to Strand to discusses his findings. Strand, who is now on the âÂÂinter-settlements committeeâÂÂ, takes John to the locked armory where they discover that a matching knife is missing, suggesting a high ranking individualâÂÂs involvement. However, back to the prison cell, a forlorn Janis confesses to murdering Cameron and accepts execution.
In anguish because he believes Janis is innocent, John goes to JacobâÂÂs and leave a letter for June. That night, John is heading out to break Janis free, when he hears the blaring of a radio: Janis has been bound outside the gates and devoured by walkers. Furious, John sets to find out who pushed forward Janisâ execution. Strand emerges, claiming it was him. The two fight, and Strand tells John he saved both his and JuneâÂÂs lives with his action.
The next day, in a formal ceremony, Virginia pins a golden key onto JohnâÂÂs chest and names him Ranger. Later, John lies in bed despondently when June arrives: Virginia has transferred June as a reward for JohnâÂÂs silence.
Elsewhere, Morgan is on the roads when his truck is hit by another car. As he gets out to investigates, two men emerge. They demand where Emile is and ask for âÂÂthe keyâÂÂ. After winning the ensuing fight, Morgan retrieves a key hanging from his neck and wonders what it unlocks.
David S.E. Zapanta of Den of Geek! rated the episode 4 out 5, and wrote: "I was surprised they were dispatched so quickly, but itâÂÂs just as well. With only four episodes left, Fear still has a lot of ground to cover. Fortunately, this is a journey worth taking." Erik Kain of Forbes in his review praised the development of John Dorie and wrote: "this was a very enjoyable episode of Fear. I liked the mystery aspects. Dillahunt did a great job throughout and John Dorie continues to be one of my favorite characters in any of The Walking Dead shows. Lots of good action both between the living and the dead and between just the living." Writing for Decider, Alex Zalben also acclaimed Dillahunt's performance, writing: "When you get into a John Dorie focused episode, you know what youâÂÂre going to get. With a voice like molasses and a generally positive outlook on the zombie apocalypse, episodes like 'Humbug's Gulch' have been a blast to watch."
The episode was seen by 1.28 million viewers in the United States on its original air date, below the previous episodes.
