When The Last of Us premiered on HBO in 2023, it faced skepticism. Video game adaptations rarely succeed critically, and zombie stories felt overdone. Yet, against the odds, the series became a cultural phenomenon, earning acclaim for its storytelling, performances, and emotional depth. With Season 2 on the horizon, it’s time to revisit the harrowing journey of Joel and Ellie—and prepare for what’s next.
It’s been over two years since the Season 1 finale, so whether you’re a die-hard fan or a newcomer, this guide will refresh your memory on the key events, characters, and themes that make The Last of Us unforgettable. From the fungus that ended the world to the moral quandaries that define its characters, here’s everything you need to know before Season 2 begins.
In The Last of Us, the apocalypse isn’t caused by a virus or nuclear war—it’s a fungus. The cordyceps fungus, which in reality infects insects, mutates to target humans. Once infected, people lose their minds, becoming violent “zombies” driven by the fungus’s need to spread.
The outbreak begins in 2003, likely through contaminated food. Within days, society collapses. By 2023, the world is a wasteland of crumbling cities, overrun by infected and ruled by brutal factions. Survivors huddle in quarantine zones or roam the wilderness, scavenging for resources.
The infected aren’t just mindless zombies—they evolve:
These creatures are connected through a fungal network, meaning killing one can alert others. This interconnectedness makes them a constant, evolving threat.
Survivors live in militarized quarantine zones run by FEDRA, a authoritarian remnant of the government. Outside, groups like the Fireflies—a rebel faction seeking a cure—fight for control. Other dangers include raiders, cannibals, and cults, each with their own twisted ideologies.
This fractured world sets the stage for Joel and Ellie’s perilous journey.
Pedro Pascal as Joel, a survivor haunted by loss.
Joel (Pedro Pascal) is a hardened smuggler in his 50s, shaped by tragedy. In 2003, during the initial outbreak, his daughter Sarah (Nico Parker) was killed by a soldier, leaving him emotionally scarred. For 20 years, Joel survives by any means necessary, smuggling goods in Boston’s quarantine zone with his partner Tess (Anna Torv).
When the Fireflies offer Joel a deal—deliver Ellie to their base in exchange for supplies—he reluctantly agrees. But as their journey unfolds, Joel’s protective instincts resurface, turning him into Ellie’s fiercest guardian.
Bella Ramsey as Ellie, a teenager with a secret that could change the world.
Ellie (Bella Ramsey) is a 14-year-old orphan with a sharp tongue and a rebellious streak. Born after the outbreak, she’s never known a normal life. What makes her special? She’s immune to the cordyceps fungus—a rarity that could lead to a cure.
Ellie’s immunity is a mystery. It’s hinted that her mother was infected while pregnant, giving Ellie a unique resistance. Her journey with Joel is as much about survival as it is about finding purpose in a world that’s lost hope.
At first, Joel sees Ellie as cargo—a means to an end. Ellie, meanwhile, is wary of Joel’s gruff demeanor. But as they face infected hordes, hostile humans, and personal losses, their bond deepens. Joel becomes a father figure to Ellie, filling the void left by Sarah’s death. By Season 1’s end, their connection is unbreakable—but it comes at a cost.
Season 1 follows Joel and Ellie’s cross-country trek to deliver her to the Fireflies. Along the way, they encounter allies, enemies, and moments of profound humanity.
The series opens in 2003, showing the chaos of the initial outbreak. Joel loses Sarah, setting the tone for his hardened outlook. Fast-forward to 2023: Joel and Tess are smugglers in Boston when they’re tasked with escorting Ellie to the Fireflies.
In the finale, Joel and Ellie reach the Fireflies in Salt Lake City. The group’s leader, Marlene (Merle Dandridge), reveals that extracting a cure from Ellie will kill her. Unwilling to lose another “daughter,” Joel massacres the Fireflies and rescues Ellie, lying to her about what happened.
This decision—saving one life at the expense of humanity’s future—sets up Season 2’s central conflict.
The Last of Us constantly asks: What are we willing to sacrifice to survive? Joel’s choice in the finale epitomizes this. By saving Ellie, he dooms the world—but preserves his own humanity. The show doesn’t shy away from the cost of survival, whether it’s Joel’s violence or Ellie’s loss of innocence.
From Bill and Frank’s romance to Joel and Ellie’s bond, love persists even in despair. But it’s fragile. Every connection risks heartbreak, as seen with Henry and Sam’s tragic end.
The Fireflies represent hope for a cure, but their methods are ruthless. Joel’s lie to Ellie protects her but denies her agency. Season 2 will likely explore whether hope is worth the sacrifices demanded.
Season 2 picks up five years after the events of Season 1. Joel and Ellie are living in Jackson, Wyoming, a thriving community led by Joel’s brother Tommy (Gabriel Luna). But peace is fleeting. The Fireflies seek revenge, and Ellie begins to question Joel’s version of events.
Based on the video game, Season 2 will introduce Abby (Kaitlyn Dever), a soldier with ties to the Fireflies. Her arrival will complicate Joel and Ellie’s relationship and force them to confront their past.
Expect Season 2 to delve deeper into the consequences of Joel’s actions. Ellie’s journey will likely focus on truth, forgiveness, and the weight of survival. As showrunners Craig Mazin and Neil Druckmann have hinted, the series will chart its own course while staying true to the game’s emotional core.
The Last of Us Season 1 redefined what a video game adaptation could be, blending action, horror, and heart. With Season 2 set to explore new depths of its characters and world, now’s the perfect time to revisit Joel and Ellie’s journey.
Whether you’re rewatching Season 1 or diving in for the first time, the story’s blend of brutal survival and tender humanity will leave you eagerly awaiting what’s next. As Riley told Ellie in “Left Behind,” life is about savoring every moment—something The Last of Us captures beautifully, even in its darkest hours.
