When The Last of Us dropped on HBO, fans of the video game and new viewers alike were floored. It wasn’t just another zombie-apocalypse show — it was emotional, it was dark, it was raw, and it was terrifying in the most grounded, real-world kind of way.

Pedro Pascal and Bella Ramsey knocked it out of the park as Joel and Ellie respectively, dragging us through fungal-infested ruins and soul-crushing moral dilemmas. But beyond the heart-wrenching story and masterful acting, The Last of Us was packed with tiny, unsettling details - the kind that don't jump out at you unless you’re really paying attention.

Maybe you were too busy sobbing over Bill and Frank’s episode. Maybe you were too tense wondering if Joel would make it out alive. But trust us - The Last of Us is a goldmine of eerie little moments and hidden clues that take the horror to a whole new level. So let’s dive into 10 chilling details you probably missed the first time around.


10 chilling details in The Last of Us you didn’t catch the first time

1) The flour theory was confirmed early on

In the very first episode of The Last of Us, there are several seemingly random moments where Joel and his family narrowly avoid eating foods made of flour - pancakes, biscuits, and even birthday cake. While it may have seemed like filler dialogue at first, it’s actually a terrifying clue. Later in the series, it’s confirmed that the Cordyceps fungus spread through contaminated flour. Yup, Joel and Sarah dodged a deadly pandemic by skipping breakfast. Who knew not having a sweet tooth could save your life?


2) The cold open is a warning we ignored

Remember that haunting cold open in episode one of The Last of Us? The scientist on the talk show warns that if fungi like Cordyceps evolve due to climate change, it could spell the end of humanity. It’s delivered calmly, almost academically - but that’s what makes it so chilling. It’s not science-fiction; it’s science-fact! The horror here isn’t jump scares - it’s the possibility that we’re just a few degrees away from this nightmare becoming real!


3) Clicker sounds are mixed with human screams

The sound design in The Last of Us deserves an award - and also maybe an apology to your ears. But here’s something you might not have realized: the terrifying shrieks of the Clickers aren’t just weird monster noises, they're layered with real human screams. That means when you hear them coming, you're not just hearing a monster - you're hearing what's left of the people they used to be. Scary!


4) Sarah’s reflection foreshadows her fate

In the first episode, when Sarah looks into the broken watch that she gets repaired for Joel, her reflection appears cracked. It’s subtle, but symbolically powerful. The watch - a gift of love, becomes a relic of trauma. That broken reflection is a quiet premonition of the shattering moment that’s about to change Joel’s life forever; and once you notice it, it sticks with you.


5) The wall shadows are a hint at the past

In several scenes, especially in abandoned buildings, you might notice strange shapes on the walls - human-shaped shadows. These are “nuclear shadows,” referencing the eerie silhouettes left behind in Hiroshima. Except here, they're caused by fungal explosions. It’s a silent, spooky nod to how quickly life was wiped out, leaving only a shadow behind. The Last of Us doesn’t draw attention to it, but it’s pure horror if you catch it!


6) Joel’s Tinnitus is more than just a detail

There are a few moments throughout The Last of Us where the sound fades into a ringing in Joel’s ears. Most viewers brush it off as just a stylistic sound cue, but it’s actually a depiction of tinnitus - a real hearing issue that veterans like Joel often suffer from. It’s a small but powerful reminder of the physical and mental scars Joel carries, even before the world went to hell. The apocalypse didn’t start his suffering - it just added to it.


7) Ellie’s knife isn’t just a weapon

Ellie is rarely seen without her switchblade. She uses it for protection, sure, but there’s more to it. The knife is the same one she used in the Left Behind flashback episode with Riley. It was likely her first kill - turning it from a toy into a survival tool. Every time she pulls it out, she’s carrying a memory of that night, of loss, and of the moment her innocence ended. It’s her anchor, and her scar.


8) The infected baby in the background

In episode two, when Tess, Joel, and Ellie pass through a ruined building, eagle-eyed viewers spotted something bone-chilling in the background: a stroller…and a small infected body slumped nearby. The camera never lingers on it, and it’s never mentioned, but it’s there - a grim reminder that this virus doesn’t discriminate. It infects everyone, even babies. The implication is horrifying, and it’s easy to miss unless you're really looking.


9) The quiet parallel between Joel and Kathleen

Kathleen, the leader of the Kansas City revolutionaries, is ruthless and vengeful. While we root against her, the show subtly draws a parallel between her and Joel. Both lost someone they loved, both went to extremes because of that loss. But while Kathleen is consumed by revenge, Joel eventually finds purpose in protecting Ellie. It’s a subtle, chilling reminder that Joel could have turned out just like her - and maybe he does sometimes too.


10) The fungus keeps the Infected “alive”

In The Last of Us video game, the Infected are more zombie-like. But the makers of the show add a disturbing twist - the fungus doesn’t just kill the host, it keeps them alive just enough to control them. That’s why some infected are seen twitching or breathing faintly, even after years. It’s not just creepy, it’s cruel. These people are prisoners in their own bodies, still biologically functioning - just no longer human. The terror here isn’t death, it’s being undone!


The Last of Us doesn’t just scare you with monsters. It scares you with meaning, with detail, with the slow realization that the horror runs deeper than you thought. So the next time you watch it, keep your eyes, and even ears, open. Because the scariest stuff isn’t what jumps out, it’s what’s already there!
