While Season 2 of The Last of Us has often plunged viewers into intense emotional depths, it has also provided instances of warmth and brightness—particularly in its finale, Episode 7.

In this installment, Ellie (portrayed by Bella Ramsey) embarks on a dangerous quest and discovers a small yet significant gift for Dina (Isabela Merced), who is expecting a baby. Amidst the ruins of a Seattle bookstore, Ellie retrieves a cherished children’s book: Jon Stone’s 1971 classic The Monster at the End of This Book, illustrated by Michael Smollin.

Indeed, that book—the one many of us recall from our youth, featuring the endearing and frantic Grover from Sesame Street. The narrative is a whimsical, fourth-wall-breaking escapade in which Grover anxiously attempts to stop the reader from turning the pages, terrified of the creature lurking at the conclusion. He constructs barriers, ties cords, and implores the reader to refrain. Ultimately, the twist reveals that Grover himself is the monster, leading to a comical and heartwarming discovery.

Witnessing Ellie select this specific book is both moving and symbolic. Firstly, it’s a story about facing one’s fears—something Dina’s child will surely need to grasp in the harsh, post-apocalyptic reality they are about to face. More significantly, it’s a narrative about self-awareness and perspective. The notion that one could be the very monster they dread resonates profoundly with Ellie’s present journey.

As Ellie battles through the ranks of the Washington Liberation Front in search of the individual accountable for Joel’s death, her actions pose challenging questions about morality, revenge, and identity. In this light, the book becomes more than just a nostalgic reference—it serves as a reflection. Who is the monster at the end of this tale?

The Last of Us Season 2 is currently streaming on HBO and HBO Max, airing on Sundays at 9 p.m. ET.
