This is the episode that proves The Last of Us is not a "zombie show." It’s a story about memory, guilt, and the terrifying courage it takes to love someone when the world has proven, over and over, that it will take them away.
The result is a tender, aching, and essential hour of television that explains everything about who Ellie is—and why she refuses to let Joel go. The episode opens right where we left off. Joel is impaled, bleeding out on a filthy mattress in a derelict Colorado mall. Ellie, a 14-year-old girl with a bloody knife and a heart full of panic, is utterly alone. The cordyceps are the least of her problems.
"Left Behind" is a risk that pays off spectacularly. It’s a smaller, quieter episode that relies entirely on character and emotion over spectacle. Storm Reid delivers a career-best performance as Riley—so full of light and life that her inevitable end feels like a personal wound.
When Riley confesses she’s been reassigned to the Fireflies’ front lines in another city, their fight is devastating because it’s so real. "You’re a soldier," Ellie spits. "I’m not going to be your friend while you go off and die." The Last of Us - Season 1- Episode 7
See you next week for the finale. Bring tissues.
Enter Riley (played with dazzling charisma by Storm Reid). Riley is Ellie’s older, cooler, missing best friend who has mysteriously returned after running off to join the Fireflies. She breaks into Ellie’s dorm room and, with a mischievous grin, whispers four magic words: "I want to show you something."
The chemistry between Bella Ramsey (Ellie) and Storm Reid (Riley) is electric. It’s not just about the obvious teenage tension; it’s about the fear of admitting you love someone. The script (co-written by game creator Neil Druckmann) captures that dizzying, terrifying moment of a first crush perfectly. This is the episode that proves The Last
And then the lights go out. The infected attack. The bite happens. Some viewers may find this episode frustrating. It’s a bottle episode that pauses Joel’s life-or-death cliffhanger for an hour. But to call this "filler" is to miss the entire point of The Last of Us .
For forty glorious minutes, The Last of Us becomes a coming-of-age teen drama. And it’s absolutely wonderful. But this is The Last of Us . The rot is always there, even in paradise.
This framing device is brilliant. It traps us in Ellie’s helplessness. And then, as the terror becomes too much, her mind does what all our minds do in crisis: it retreats to a happier memory. A "before." That memory is the heart of the episode. We flash back to a time before the Boston QZ, before Marlene, before the Fireflies. Ellie is a newly-orphaned teen in a FEDRA military school. She’s angry, sharp-tongued, and desperately lonely. Joel is impaled, bleeding out on a filthy
That trauma explains her ferocious loyalty to Joel. She cannot lose another person she loves. She will not abandon him. When we cut back to the present, and Ellie whispers, "I’m not going anywhere," while she rips open her backpack to sew Joel’s wound with thread from her own jacket, the moment carries the weight of a Greek tragedy. Rating: 9/10
If the previous episode, "Kin," was a masterclass in quiet, devastating grief, then Episode 7, "Left Behind," is a love letter written in the margins of the apocalypse. Titled after the game’s celebrated DLC, this episode takes a full step away from Joel’s knife-edge survival and plunges us headfirst into Ellie’s past.
We watch her try to stitch Joel’s wound. We watch her fail. We watch her realize that the man who has become her surrogate father is slipping away, and she has no medicine, no car, and no plan.
