The fifth and final season of this sci-fi action dramedy, which has been delivering the thrills at a breakneck pace lately, hits its penultimate episode tonight with the new episode "Terraformance Anxiety." It finds the Lady’s nefarious scheme — to alter the atmosphere of Westerly to accommodate her new master race — becoming a reality. That means that moon will be totally uninhabitable for humans, sending Dutch, John and D’avin (Hannah John-Kamen, Aaron Ashmore, Luke Macfarlane) scrambling to stop her.
