Mortal Cinema: The future Ferengi mask from Discovery gets some reuse. Darem presents as human but is actually a blue alien who can shape-shift. The entire fifth episode is a tribute of sorts to Deep Space Nine, with some Marvel-style surprises. No, Avery Brooks isn’t back; you’d have heard by now if he were. But the episode, cowritten by Lower Decks’ Tawny Newsome, is as loaded with Easter eggs as Lower Decks, and features a new role for Newsome in live-action that isn’t Beckett Mariner. Chiwetel Ejiofor, whom I can only assume is as big a fan as Paul Giamatti, performs a key voice-over without ever showing his face on camera.
