Warning: Spoilers ahead for Star Trek: Lower Decks season 5, episode 1, “Dos Cerritos.”With the fifth and final season of Star Trek: Lower Decks underway, the season 5 premiere ends with a brilliant tease that could mean a permanent multiversal character switch has been made. The Star Trek: Lower Decks season 5 cast won’t be reuniting once the finale hits Paramount+ on December 19, 2024 – at least not in the current context. So, if the switch in question has taken place, it would make sense for the show to reverse the process before the last episode. Otherwise, it could be a massive turning point in Lower Decks and the general Star Trek canon.
