!!This episode provides examples of

* TheCavalry: Right at the beginning of the episode, Mortu and the Utroms come to the Turtles' and Professor Honeycutt's aid just in time.
* FailedASpotCheck: Both the Utroms and the Turtles miss that only two of the three Triceratons get sent back.
* {{Foreshadowing}}: One of the Triceratons slips away in the confusion and [[Recap/TeenageMutantNinjaTurtles2003S2E19RogueInTheHousePart1 ends up in the sewers]].
* GoodAllAlong: The Utroms turn out to not be as villainous as the Turtles thought.
* LosingYourHead: Baxter Stockman managed to survive [[Recap/TeenageMutantNinjaTurtles2003S1E23ReturnToNewYorkPart3 the explosion]], but has been reduced to this.
* MentalFusion: The Turtles and Master Splinter enter the Utroms' Oracle Pods and simultaneously share the collective history of the Utroms.
* NotSoAboveItAll: During the simulation, Mikey spots some food and repeatedly tries to grab it, even though it's a hologram. Master Splinter is just as amused by this display as the other turtles are.
-->'''Splinter:''' There is some sort of lesson here, but I'm enjoying this too much to think what it is.
* ShoutOut: Mikey says [[{{Franchise/Alien}} "I've seen this movie. We're not going to have anything burst out of our chests, are we?"]]
* StrangeMindsThinkAlike: Both Raph and the past version of Mortu have the same response to Ch'rell's threat: "Big talk, little slimeball."
-->'''Raph:''' [[LampshadeHanging Hey, I like the way this Mortu guy thinks.]]
* TimeDilation: According to Splinter, the Turtles were only gone for eight hours, even though it was three weeks from their perspective. Mortu attempts to explain with scientific terms and (unsurprisingly) only Donatello gets it.
* WhamEpisode: The Utroms are revealed, and the Turtles are finally home from space and reunited with Splinter.
