Throughout the entire seven-season run of Star Trek: Voyager, Ensign Harry Kim remained at the same rank. Yes in the alternate future of Endgame, Harry Kim was a captain, but that moment of ranking up is the exception that proves the rule; though he was a brave and innovative officer, Janeway (and the Voyager writers) never thought to give Kim a promotion beyond the basest of Star Trek ranks. And if Kim was given more overt authority on the show, it would sometimes be thanks to an alternate timeline.
And now, as Star Trek crosses the multiverse in the penultimate episode of Lower Decks with a slew of legacy character cameos, the most prominent returning character is none other than Harry Kim. And this time, one version of him is a full lieutenant.
