And setting up the mean-spirited "poor dumb Harry Kim" trope that's been circulating endlessly around the Internet for the past 22 years.And the Endgame future was the original prime timeline before Admiral Janeway went back in time and changed it for her own selfish reasons, thereby denying Harry Kim a promotion and a ship to command, still being an ensign in 2401.
The disturbing thing is that unless Harry was already added to Prodigy S2 (and it gets aired), the only series remaining set in that time period is "Lower Decks", and it'd right up their alley to have Harry still be an ensign. So, the wrong that the VOY showrunners did may never be righted.
