The Last of Us Series I hope at least part of Left Behind is in the show. By Rachel LeishmanJun 4th, 2021, 12:17 pm Ellie talks to Joel about her “friend” who died in The Last of Us. Joel is opening up to Ellie and talking about his daughter Sarah, and Ellie brings up her friend Riley. At the time, we don’t know much, just that Riley is who Ellie was with when she was bitten by one of the zombie-like “infected,” and Riley continued to become infected while Ellie did not. But when playing through the downloadable story extension Left Behind, we get to see a look into Ellie’s past with Riley, as well as her struggle to keep Joel Miller alive when he falls and impales himself on a metal rod. Flashing back and forth between her searching for some medicine for him and her past with Riley, we learn a lot about what makes Ellie tick, and how she ended up with Joel in the first place.
