In its nine episodes, Pluribus quietly dismantled the alien invasion genre and rebuilt it in the signature storytelling style of Breaking Bad creator Vince Gilligan. Just a few years out from the start of the COVID-19 pandemic, the hit Apple TV series introduced a novel disease where most of the world's population contracts an otherworldly happiness virus.

At the center of the story is Carol Sturka (played by Rhea Seehorn of Better Call Saul), a successful yet cantankerous romance novelist. When reality around her shifts -- and it does so quickly -- her grumpy demeanor sets her apart from the happy hive mind that takes shape. She makes it her mission to set things right, but it isn't a simple task.

The ninth episode, titled La Chica o El Mundo, hits like a silent bomb. Its final moments recenter the show's emotional stakes and urgency. What does it all mean? Where do things go from here? I sat down for a chat with Seehorn to dig into Carol's mindset, the watershed moment that snapped her back into reality and her potentially incendiary motivations moving forward.

If you're not caught up on the Pluribus finale, turn back now. Major story spoilers follow.

The final act of the episode revealed Carol's chilling realization. Although she had officially told the hive mind they did not have her consent to access her stem cells in order to turn her, in fact, Zosia (Karolina Wydra) and the rest had been actively tinkering with a workaround: her frozen eggs. Up until that moment, Carol had been romantically involved with Zosia, an understandable move after being abandoned by the hive mind to live a solitary existence as the only person in the entire state of New Mexico.

But this betrayal? It was the slap in the face Carol needed. According to Seehorn, the scene exists in layers and informs Carol's fight to maintain her free will and unexpressed grief over the death of her wife. "First of all, I thought I had to give consent," Seehorn said. So did we.

"That's being taken away," Seehorn said. "That clock is now ticking again, and you're going to lose your individuality. On top of that, the idea that this entire time, someone would say they have real care for me, and that behind my back, you were still plotting to change me. Even intellectually, Carol probably could have guessed that, because of their biological imperative. But it feels like it's drawing attention to the fact that Carol knows she was a fool."

Losing a loved one at the same time the world loses most of its humanity would probably make me do foolish things too.

If you've been paying attention, the potential romance with Zosia was there from the first moment they met. Pursuing physical love -- and even the false idea of emotional love -- to comfort oneself after a deeply traumatic experience doesn't feel like a poor decision. It's that perspective that makes the following detail all the more backstabby.

"The third rail is, of all ways to do it, the eggs that I froze that represented my future with my wife, who's now dead because of them," Seehorn said. "I don't know how a betrayal gets worse, really. You could argue, is it heroic that she finally snaps out of it only when it's endangering her? At the same time, I would counterargue that everyone else is telling me they're fine. It wasn't like I could fight for everybody anymore. They don't want to fight these people. They don't want to save the world, except for Manousos, who just wants to obliterate people, which is not the way to go."

In our chat, Seehorn compared this breakup scene with Zosia to the diner scene that takes place in Episode 8, Charm Offensive. It was Carol's favorite place to write when she was young, and it had apparently burned down, only for the hive mind to rebuild it and put her in a nostalgia-driven manipulation.

Was the relationship with Zosia the same thing? I think so, but Seehorn said that is up to interpretation. However, she was not expecting the questions about love -- and the things we do for it and how we react to it -- that Pluribus brought up in her.

"As the show does so well, for me, it unraveled a lot of questions about, like, how are you judging what real love is like?" Seehorn said. "Real love can't have any objective when we do loving things for people that we love? We often have an objective: I want you to love me back. I want to make you happy. So it was a pretty deep dive into what is actually going on here."

So what is Carol's state of mind now? Is she in a better place than where she was when she aimed that lit firework canon directly at her face in Episode 7, The Gap? I wouldn't say better, but it definitely is a different place.

For one thing, she now has a weapon of mass destruction sitting outside her house. What is her plan with it? Seehorn didn't have a comment about that, but if you look at the third episode, titled Grenade, and how Zosia reacted to that explosion, I have a sneaking suspicion that leveling up to a way bigger bomb will disrupt the world -- the hive mind's world, that is.

As for Carol, "she is scared, defensive, hurt, ashamed and embarrassed," Seehorn said. "As we've seen, she's very reactive and very impulsive with a little streak of rage in there, and she can't sit in those feelings."

It took two days to shoot the scene with Zosia, Seehorn told me, as everyone explored the emotional spectrum of this betrayal from all angles. "In the end, I saw the take they chose, which almost receded," she said. "We were trying out something where I refused to be vulnerable in front of these people ever again. You don't even deserve to see how angry or how upset I am."

Seehorn continued with a laugh: "She just turns on a dime and says, 'I need an atomic bomb, and I'm out.'"

The first season of Pluribus is available to stream on Apple TV.
