Spoilers below for the latest episode of Fear the Walking Dead, so be sure to watch before reading on.
In its first three episodes, Fear the Walking Dead had a completely different game plan than it did in years past, with new characters facing new situations, but harboring the same potential for emotionally debilitating disasters like Nick's recent death. "Buried" finally gave viewers more insight into what actually happened with the O.G. crew before they crossed paths with Morgan & Co., which led to some big reveals about many major characters. As one might have imagined, there was heartbreak involved. Let's go down the list and break down all the big catalysts that brought these characters to the present. (The ones who made it, anyway.)
Jenna Elfman's Fear the Walking Dead debut offered little about her backstory, and basically showed off how well she could fight zombies while covered in muck. But "Buried" opened things up and, assuming she was telling Alicia the truth, we learned Naomi was an ICU nurse before society collapsed. So it was good that she ended up finding all those medical supplies at that horrifying water park.
We also learned that even though Naomi initially wanted to leave everyone behind -- and possibly only didn't because the vehicle she found was out of gas -- she inevitably decided to stick around and put together a slapdash ICU unit within the Diamond. Unfortunately, Alicia revealed late in the episode that Naomi died trying to protect the Diamond, and that the Vultures are to blame. But it turns out she didn't always go by Naomi...
John's Tragic Reveal
As John was driving the mish-mashed group to Alicia & Co.'s destination (which ended up being a buried cache of weapons and other supplies), Al was recording the others sharing their indirect stories about what happened to the diamond. In the final minutes, as the group's next steps were being decided, John recognized a bag among the rest, and believed it to belong to his long lost Laura. Through a quick flashback, we saw the bag belonged to Naomi, who was in possession of the pistol twin that John had brought up in a previous episode. So yes, Laura and Naomi are/were the same person.
It was then that the character's death was revealed, which was a major blow to John's senses, and it could possibly destroy his good-natured attitude for good. Morgan stayed behind with John while Al drove the others on their continuing quest, so there's a chance we might hear Morgan discussing his own lost loves in the next episode.
