Warning: Contains SPOILERS for HBO's The Last of Us and The Last of Us gameParallels in the deaths of side characters in The Last of Us act as foreshadowing for Joel and Ellie's ending. The video game-based HBO series has taken its creative liberties with expanding on the events of its source material to provide more emotionally impactful narrative. While these choices have succeeded in producing strong television episodes, they also appear to be foreshadowing later events that will be taken directly from the game.
