3. Infinite slightly wrong Enterprises
Where the previous zooms out to the level of galactic history, The Next Generation episode “Parallels” takes a more quantum approach. On his way back from a bat’leth tournament, Worf begins slipping between parallel realities, each just a little different from the last: he’s married to Troi in one timeline, Picard is dead, and Riker commands the ship in another, and in the darkest branch, the Borg have overrun the Federation.
The episode’s climax is about as Mirror‑esque as TNG gets visually, with an armada of Enterprises crowding the viewscreen and a heavily‑scarred, battle‑ready ship from a Borg‑ravaged universe refusing to stand down. Worf clings to his own sense of identity while the universe keeps presenting him with versions of his life that are tempting, unsettling, or both.
Instead of a single fascist counterpart to Starfleet, “Parallels” imagines infinite moral drift: for every optimistic Federation, there’s one that got crushed; for every comfortable status quo, there’s one where grief or war hardened the crew in ways that feel alien to Worf. Choosing the “right” reality isn’t about spotting an evil symbol; it’s about recognizing the relationships and values that feel authentic.
