Star Trek: Lower Decks quietly delights in showing characters with humble beginnings rising to impressive heights. Figures like Sonia Gomez (best known for spilling hot chocolate on Jean-Luc Picard) become captains of their own starship, while Star Trek: Deep Space Nine's bartender Quark now owns an entire franchise. None of them, however, have risen so high as Rom and Leeta, Ferenginar's preeminent power couple who make a prominent appearance in Lower Decks Season 4, Episode 6, "Parth Ferengi's Heart Place." Not bad for a former waiter and dabo girl.
