A group arrives at a ruined city, sparking a heated debate over whether the doomsday and giants truly ended. Alan’s claim that the threats persist clashes with Chelsea and others who insist the giants are gone and Alan deceived everyone for power. Despite doubts, the evidence of destruction convinces some to prepare to return to the surface. Alan orders the team to contact an ally and set up a nearby camp as they plan to leave underground. Meanwhile, an ominous presence senses the humans above, hinting danger even as the fortress reopens after years.
