Last Sunday’s episode of The Last of Us titled “Left Behind” served mainly to give the viewer insight into Ellie’s mysterious past. The viewer knows Ellie is different, not just because of the antibodies coursing through her blood, but because of her ability to find joy amidst the surrounding shrapnel. “Left Behind” takes us to the quarantine zone, where some normal aspects of life like school take place — albeit more militantly than normal — even with the threat of impending infection. The viewer finds Ellie to be almost as bold in the past as she is in the show’s main timeline.
Her classmate Bethany learns this when she berates Ellie for her slow running pace and reminds her that her missing best friend Riley (Storm Reid) is no longer around to fight for her. Upon mention of her bestie, Ellie clocks Bethany squarely in the face without much thought.
