Joel's brother Tommy is the one flickering point of stability left. Living in Jackson among people, a wife, and a life. He is evidence that survival does not always equal isolation. Joel finds he envies it and rejects it. He wants to drive Ellie away, separate her from Tommy, and shield himself from what he already knows—he loves her. He also understands the expenses of loving someone in this world.
Ellie, for her part, isn’t just a passenger in this journey. She’s actively becoming someone. The DLC, Left Behind, is essential to understanding her, not because it adds lore, but because it shows what she’s lost. Riley wasn’t just her friend; she was the one person Ellie let herself believe in. When she died, Ellie was left with a bite mark and a mountain of survivor’s guilt. And then Joel lied to her. Took her purpose, twisted it into a secret, and tried to build something with her on top of that lie.
The heartbreak of The Last of Us 2 game isn’t just Joel dying—it’s Ellie never getting to forgive him while he was alive. She tells him she's willing to try at last, the night before his death. That little, visceral instant is the core of all that follows. Ellie slides into violence, her grief displaced rather than merely seeking retribution. Mangled love. From Jesse to Dina to Lev, every individual she interacts with in Part II is another mirror. Still another opportunity for introspection or breaking free.
And then Abby comes around. Until you do, the type of person that really irritates you so profoundly that you cannot even see straight. Until the game makes you sit in her shoes, live through her losses, and understand that the same despair that twists Ellie into a ghost has done the same to her. Joel ties Abby and Ellie together. Through what he did and what he intended. Whether as a father or as a symbol, how loving he was destroyed them both in different ways.
