Sony has revealed more details about the much-anticipated PlayStation 4 game The Last of Us: Part II. In a blog post, director Neil Druckmann discussed Ellie and her motivations, while he also confirmed the role of another celebrity who is working on the game.

We knew Ellie was older in The Last of Us: Part II, but now Druckmann confirmed that she is 19 years old. After the horrific events of the first game, Ellie has found "a semblance of peace and normality." She is on a path towards finding peace in her world--but it doesn't last.
