Star Trek has given fans plenty of tragic romances over the years. James T. Kirk And Edith Keeler, Jadzia Dax and Worf, Kira Nerys and Vedek Bareil, Michael Burnham and Ash Tyler, and, of course, Subcommander T'Pol and Commander Charles "Trip" Tucker. In the Prime Universe, their relationship was marred by one tragedy after another, but in this week's episode of Star Trek: Lower Decks, fans get to see what could have been.
