- Ensemble Darkhorse: Lucas and Darwin were consistently the most popular characters.
- Harsher in Hindsight : In "The Regulator", the villain of the episode faked his own death by suicide to avoid condemnation by his peers. Lucas responds by saying "I can sympathize." Knowing that Lucas' own actor, Jonathan Brandis, would later go on to commit suicide makes for a truly cringe-worthy "Funny Aneurysm" Moment. It's even worse when you consider the fact that the villain faked his death in 2003, the same year as Brandis' actual suicide.
- Hilarious in Hindsight: Both involving O'Neill.
- In "Watergate", O'Neill revealed that he knew ancient Greek. This would not be the only time his character would speak Greek.
- In "Dagger Redux," Bridger and O'Neill were conversing at the end about returning home. Bridger makes a quote and explains it, and O'Neill replies with, "I thought it was 'The Wizard of Oz.'" Ted Raimi would later cameo in Oz the Great and Powerful.
- I Want My Jetpack: Became this now that the year 2018 has passed. Colonizing the oceans is still a pipe dream, and the seaQuest's biomechanical design is impractical, but a few technologies casually mentioned on the show (such as interactive movies and social media) have analogs in modern times depending upon how you define them.
- Nightmare Fuel: "Knight of Shadows", fitting for the show's Halloween episode. To cap them all, we have a mysterious set of directions, an apparition hurtling Bridger across his room, a man looking straight at the main characters during a paused video, something alternatively setting doorknobs on fire (literally) or freezing them solid for threat of frostbite, and threatening them in general.
- Suspiciously Similar Song: Much of the background music in "The Fear That Follows" is based on "Mars, the Bringer of War" from The Planets by Gustav Holst.
YMMV / seaQuest DSV
