One of the major appeals of the post-apocalypse show is how quickly the world can go from day-to-day life to an absolute wasteland. Fallout started its entire story with a first-hand look at the apocalyptic event before flashing forward over a century. Other shows intercut the events of the apocalypse with what landed them in that situation.
But sometimes, an apocalypse story creates more appeal by not showing the apocalyptic event that happened at all, leaving it a complete mystery to the viewer and, in the case of the Apple TV+ series Silo, to the characters as well. But that all changed at the end of Season 2 with a scene that explains a Season 1 prop — and references a key part of the source material.
