Episode 2, “Through the Valley,” brilliantly delivers on The Last of Us’ most emotional and fateful plotline. It revels in its unnerving anxiety from start to finish, creating incredible uncomfortability and ensuring that both the viewer and the series will never be the same. Its addition of budget-busting infected sequences is some of the best work that we’ve seen in television, and its infamous series-altering scene leaves the viewer thinking about even more than what just happened in possibly the best episode in the series to date.
