The USS Cerritos' visiting Vulcan science officer, T'Lyn, takes center stage in the latest episode of Star Trek: Lower Decks. The fourth season reaches its halfway point with its fifth episode, "Empathological Fallacies." The episode has the Cerritos fall into complete chaos, leaving the emotionally stoic T'Lyn as the starship's best hope to restore order before it's too late. With a concentrated dose of unbridled mayhem, the episode runs dangerously close to running entirely off the rails -- but manages to stick the landing.
