The story of brothers Henry and Sam is the subject of The Last of Us Episode 5, with the HBO TV adaptation adding a significant amount of new narrative context. The continuing theme of what keeps us going when all is lost is explored once more, and thrown into the context of how our own selfish actions impact the wider community around us.
Though ostensibly a two-episode side-story, this version of Henry and Sam’s story appears to have a much greater impact on Joel and Ellie’s relationship and understanding of their post-apocalyptic world. It explores all that can be gained, and how quickly it can all come crumbling down.
