The article argues that Silo’s adaptation of Daniel Keene’s storyline is a purposeful improvement on the source novel, despite some viewers’ concerns about increasing departures from Hugh Howey’s Shift. In the latest episode, Daniel rejects joining the silo project, unlike his book counterpart, making him less of a willing participant in creating the future shelters and strengthening his television character arc.

Howey defended the alteration in a fan group, saying it is important to Daniel’s arc and will become clearer in the season’s final two episodes. In Shift, Donald Keene is a freshman congressman and architect who accepts Senator Thurman’s project under the false belief that it is a nuclear-waste facility; he remains involved partly for political advancement and does not understand its true purpose until much later.
