Jennifer Maas TV Business WriterThe first season of Apple’s “Severance” concludes with a jam-packed finale that sees the Innie ver- sions of MDR employees Mark (Adam Scott), Helly (Britt Lower) and Irving (John Turturro) awaken in the real world for the first time during an escape attempt, which leads Helly to find out she’s actually the Lumon CEO’s daugh- ter, Mark to realize his wife, Gemma (Dichen Lachman), is alive and Irving to discover Burt’s (Christopher Walken) Outtie has a part- ner, all in just a few scenes. Constructing the episode in which Milchick (Tramell Tillman) and Cobel (Patricia Arquette) realize what’s going on and then try to stop it, all while Dylan (Zach Cherry) is desperately trying to simultaneously hold the control room switches that will keep his friends awake, required more effort than the eight episodes that came before it.
