Star Trek: Lower Decks takes a deep dive into Star Trek lore for its Season 4 finale. "Old Friends, New Planets," focuses on Nick Locarno, the Totally Not Tom Paris clone played by Robert Duncan McNeill. He has been up to no good since his expulsion from Starfleet Academy in Star Trek: The Next Generation Season 5, Episode 19, "The First Duty." He's behind the attacks on the various non-Federation ships throughout Season 4, with the intention of building an independent fleet full of Lower Deckies from various vessels.
