- Broken Base: One of the more divisive episodes — it's either a harmless bit of nonsense with enough fun bits to paper over the plot holes, or it's a thoroughly idiotic idea for a Star Trek episode that should never have been done at all.
- Fridge Brilliance: How does Worf's son Alexander (among others) know he's talking to Captain Picard when the Ferengi toss him in with the children? Picard is still wearing his somewhat ill-fitting uniform (complete with the four pips indicating his rank), and as an episode of Star Trek: Voyager would later clarify, Federation replicators weren't allowed to make those symbols of rank for just anybody.
- "Funny Aneurysm" Moment: Upon being de-aged to a child, Picard is relieved of command, after which he wonders what will happen to his Starfleet career, telling Troi "I've spent thirty years of my life aboard starships. I'm not about to sit behind a desk now." In "Tapestry" later this season, Picard takes the opportunity to avoid his near-fatal brawl with Nausicaans, but it totally changes his past so that in the present, he's a lowly science officer paper-pusher, not a badass captain we know and love.
- Never Live It Down: The inept fight that the Enteprise puts up against the Ferengi in this episode is almost as notorious as the battle that led to the ship's eventual destruction in Star Trek: Generations. Notably, this is the last time that the Ferengi are depicted as trying to enact an Evil Plan by force -their subsequent appearances in Star Trek: Deep Space Nine instead have villainous Ferengi work either via proxy or through shady business dealings- as their actually managing to defeat the Enterprise simply didn't seem credible to viewers.
- This gets a great Call-Back in a later episode of Star Trek: Deep Space Nine, Odo even throws this in Worf's face after Worf complains — not for the first time — about how lax security is on Deep Space Nine and makes the amusing statement that "Nothing like this ever happened on the Enterprise." Worf is suitably embarrassed.
- Tear Jerker: When Molly fails to recognize her mommy in the transformed Keiko, it hits Keiko — and us — hard.
- Her husband comforting her afterwards is equally this and Heartwarming Moments.
- WTH, Casting Agency?: Oddly zig-zagged. Giving the role of the de-aged Picard to David Tristan Birkin, who had previously played Picard's nephew Rene back in "Family," would have actually been a pretty good bit of casting... had the episode been produced later in Season 4. By Season 6, however, Birkin was a teenager and older than the script really called for. Admittedly, this wasn't helped by a writing snarl; while it could have been justifiable for Picard to look older than the others after de-ageing, as he was a fair bit older than Keiko and Ro to begin with, adding in Guinan -who is several times the combined ages of the other three- messes things up, as she also ends up looking considerably younger than Picard. Picard's condition suggests that the accident de-aged them by a set number of years, while Guinan's suggests it reverted them all to the same fixed age.
- Or at least to the same state of biological development. Girls tend to both start (by a few months) and end (by a couple of years) puberty earlier than boys, and puberty progresses at different rates for them as well. That is why men tend to be taller than women — however, it wouldn't explain why the de-aged Picard is considerably taller than the de-aged Ro, Keiko and Guinan, when all four of them are at the effective biological age of 12.
