- Accidental Aesop: Some fans have taken issue with the episode appearing to advocate the theory of intelligent design. However, the Ancient One does talk of life having evolved, so it's pretty clear the episode is still advocating evolution all the way down — it's just that it isn't Earth where the evolution happened.
- Harsher in Hindsight:
- The ending, when the Romulan Commander privately expresses hope to Picard that the Federation and Romulans may stand in friendship together someday, has become this thanks to Star Trek (2009), which showed the obliteration of Romulus.
- Star Trek Online, however, has shown that despite the destruction of Romulus, the survivors have indeed become friends to the Federation, coming together with both them and the Klingons to form the Alliance.
- And then right back around to Harsher again in Star Trek: Picard, which shows that the Federation outright abandoned the Romulans (though at least some Romulans are still deeply grateful to Picard for his efforts on their behalf, up to sacrificing his career when he Rage Quit Starfleet over their refusal to help after the Mars Incident).
- ...and now Star Trek: Discovery reveals that after the surviving Romulans relocated to Vulcan, subsequently renamed Ni'Var, they not only joined the Federation but were strongly in favor of the planet's remaining within the Federation after the Burn — while the Vulcan majority opposed it.
- Heartwarming Moments: Who is it that most takes the message of the Precursors to heart? The Federation's ally, the Klingons? The Cardassians? No. It's the Romulans, of all people, who are most willing to consider the meaning of what was left for them to find.
- Retroactive Recognition: The actress who played the hologram of the precursor race is Salome Jens, who would later go on to play another similarly-looking character (though considerably less of a friend to all species) on Star Trek: Deep Space Nine.
