This sci-fi drama concludes Season 3 with a pair of back-to-back episodes, starting with "I Ain't Goin' Out Like That," in which Isobel (Lily Cowles) helps Kyle (Michael Trevino) save a life. Meanwhile, Jones (Nathan Dean) needs something from Michael (Michael Vlamis), while Liz and Heath (Jeanine Mason, guest star Steven Krueger) refine their plot to stop Jones. Then, in a finale called "Never Let You Go," Liz must trust herself if she's to have any chance of saving the man she loves.
