The end of Star Trek: Lower Decks Season 4 is fast-approaching, hopefully with answers about the mysterious ship capturing alien vessels plaguing the galaxy. However, Episode 8, "Caves," examines Star Trek's fascination with caves, and how often Starfleet crews end up stuck in them fighting for their lives. However, this episode also centers on what it is about Gene Roddenberry's universe that allows these series and films to endure years after their debut: friendship. The relationship Starfleet officers have with caves on and (apparently) off-screen pokes fun at the reality of making a science fiction adventure show on a TV schedule.
