* KickTheSonOfABitch: Zaheer gets hit with this pretty hard, first by [[spoiler: Artana berating him for his failures]] and then [[spoiler: Korra using bloodbending to render him unable to enter the Spirit World]].

** [[spoiler: Lampshaded by Asami. She improved upon the original concept, to see if she could, and designed a [[Franchise/MetalGear bipedal tank]], which would have been a fraction of the original's size and cost had she ever constructed it]].

* SurprisinglyRealisticOutcome:
** Asami is in a world of pain over her father's death, and finally starting a relationship with Korra and going on a vacation won't fix that (though Korra ''is'' able to support and help her through it, and she's slowly getting better as time goes on).
** Kuvira may have given up, but her army is still massive and will uphold her former ideals even if she won't. It seems Suyin's belief they were a KeystoneArmy of unwilling conscripts was inaccurate. They're also entrenched throughout the territory and fortresses which resisted the Fire Nation for a century, and won't be beaten easily.
** The Colossus was an engineering and logistical nightmare which worked partly due to dumb luck, and used so much metal, acquiring enough material to build a new one isn't possible.
** A major plot point is the fact that, just like nuclear weaponry in our world, spirit vine weapons aren't just going to go away, and the ease which they can be made is recognized as a serious problem that isn't just going to vanish either, with terrorists trying to steal them, and Asami and Varrick spend a not-insignificant amount of time trying to find a way to solve the issue before an ApocalypseHow situation occurs.
** [[spoiler: When Asami finds out that Raiko had been lying and telling Kuvira that she had killed Bataar Jr. when she fired the spirit beam on the warehouse, she gets him to forget Kuvira's FreakOut (prompted by her finding out her fiancee was still alive) and pardon Bataar to help organize Future Industries's weapons development by pointing out that what he did is pretty much psychological torture on a prisoner of war, and it would ''not'' look good for him if it came to light (to the point that he'd face legal charges, and Asami would ensure that he got convicted)]].
** [[spoiler: The Red Lotus didn't just disappear because of Zaheer's recapture, and now that the Earth Empire has fractured, they're crawling back out of the woodwork to prolong the fighting and anarchy]].

* NotSoDifferent: Korra repeats this sentiment about Kuvira.
** [[spoiler: Observant readers have also noted the same applies to Asami and Artana.]]

* KiAttacks: [[spoiler: The bending-booster suit allows this ability in non-benders, such as Asami]].

The story is actually Part 7 of the [[http://archiveofourown.org/series/188699 Spin the Rails series]], which also includes Fanfic/SeekingSato by Ficsandmusings, but constitutes the entirety of the post-series content while also containing numerous references to other works within the series. It is recommended the preceding 6 stories be read before this one, since each one is a gap filler for different points in the canon timeline proper.

* AwesomeButImpractical: Discussed regarding the Colossus. It was apparently a massive pain to engineer, despite the simplicity of just attaching the spirit energy weapon to one of the many, many airships available, but Kuvira wanted a psychological weapon and personal control.

* ThePowerOfLove: [[spoiler: Invoked and lampshaded explicitly several times as the means Asami used to go BeyondTheImpossible and defeat Artana, complete with her own BattleAura]]. [[YouHaveGOTToBeKiddingMeThe villain is less than amused.]]

* AscendedFridgeHorror: It's been noted that Asami stating she "couldn't handle" losing Korra and her father in the same day could indicate she may have contemplated suicide at some point. Here, she's having a serious mental breakdown over her loss.
** Another major plotline deals with the potential destructive power of spirit vine weapons, and how easy they are to make.
** The sheer destructive power of lavabending has been ingrained in the minds of viewers since they first saw Ghazan do it, and they've wondered what might happen if Bolin taught it to someone without his moral scruples, like one of Kuvira's supporters. Apparently he ''did'' try and teach it to some of the Earth Empire soldiers, but failed because him learning it was an example of AchievementsInIgnorance and he wasn't able to ''explain'' it. Bolin himself has a bit of a FreakOut in the Swamp when he realizes this after a vision of him lavabending out of control.
** Similarly, ever since lavabending was confirmed to be canon, [[spoiler:some fans have wondered if, since glass forms at a lower temperature than lava, if it was possible to create glass in a similar manner. The Red Lotus Sandbender shows that, yes, you can]].
** [[spoiler:Speaking of the Red Lotus, ever since Zaheer was captured, fans have been wondering if there were any members left. Now, they’re apparently manipulating things behind the scenes to inspire anarchy]].

* ThePowerOfLove: [[spoiler: Invoked and lampshaded explicitly several times as the means Asami used to go BeyondTheImpossible and defeat Artana, complete with her own BattleAura]]. The villain is less than amused.

* YouHave48Hours: Once Team Avatar starts working on their battle plan, they have about forty hours left to save the world.
