* The ending of "Membership Drive", has one for Nano. Ever since he gained sentience, the poor nanomachine has been used [[ObliviouslyEvil unwitting used]] [[NotEvilJustMisunderstoodd for evil]], only desired a family, and had to be taken down by the turtles in each of their encounters. Here, instead of destroying him, the turtles help him, allowing him to finally cement his position as a good guy and joins the Justice Force, [[EarnYourHappyEnding finally giving him a place where he belongs]].

* In the third overall episode of the series, after the turtles have rescued April from Stockman's mouser-robots and she finally accepts the fact that Splinter (who's a rat) and the turtles are real, Splinter's worried that April will expose the existence of himself and his sons. But April, grateful to them for saving her as well as realizing that no one would believe her even if she did tell them (which she points out to them), assures Splinter that she really won't tell anyone. Splinter then decides to go with his gut instinct and just trusts April's word.

*** And if you remember, this was also during Leo's stage in the show where after the battle with Shredder he was generally upset and angry most of the time. Showing that he's still there despite what's happened
*** Really, just the fact that Leo's willing to train Mikey when his brothers and even Splinter refuse, thinking it a long-overdue does of LaserGuidedKarma. [[BigBrotherMentor Leo]] really takes his position as the leader seriously.

** Starlee's devotion to Cody is also sweet; they make a cute couple.

* Zixx offhandedly mentions the state of the Triceraton Republic when they're confronted by Boss Zuko's gang. He claims that the Triceratons aren't what they ''used'' to be: meaning that Traximus successfully restored the Triceratons to their former glory and dramatically improved their standing and perception in the universe.
