I plan on going back and analyzing the first five episodes as well, but seeing as Episode 6 airs tomorrow, I figured I might as well throw some ideas out there and see how they pan out:
1.Something happened to Aang
I mean, he died, obviously, but how? He was only 66 at the time of his death, and given that people seem to regularly live to be 100 or so in this universe, that seems awful young.
What we know is that Amon can take away people’s bending like Aang could, Korra has never been able to airbend, and when Korra told Tenzin about Amon at the end of Episode 3, his surprise seemed feigned, like he knows something.
Putting that all together, it’s possible that whoever Amon is, he stole or inherited Aang’s powers, to the point that they weren’t passed on to Korra, which is why she can’t airbend and has so far never reached the Avatar State.
2.Asami works for Amon
I know it’s already a popular theory that Asami is an Equalist, but my reasoning is different from a lot of what I’ve seen. Asami hasn’t said or done anything to even hint at this. And that’s just my point. For a series that has been historically great at characterization, for some reason Asami has so far been given absolutely no motives for any of her behavior. She was sidelined through almost all of Episode 5, the “relationships” episode, which is not something you do if she’s supposed to be a valid romantic interest.
The problem with this is that, so far, she’s been written merely as a plot device and hasn’t been developed any further than that. She showed up at just the right time and had just the right resources to keep the Fire Ferrets in the tournament, and provided another node to the love polygon. But beyond that… she doesn’t do anything. And my faith in the writers leads me to believe there has to be a reason she hasn’t been given any solid integration to the team or real characterization other than being “nice”.
Then there’s the fact that she has no profile on “Welcome to Republic City”, nor is she included in any of the promotional images of the team, leading me to believe the reason for this is that she’s either such a minor character that she’ll be gone by the next episode, or that any real description of her character would be a spoiler. If she does unceremoniously bow out quickly, then she really was nothing more than a plot device and I find that a bit infuriating. So my hope that she has some connection to Amon is more out of the desire for her to be reclaimed as a character with tangible motives. Like, she was a pawn and purposely hit Mako (“How could you not see me?!”) to infiltrate the team, she watches every match to learn their techniques, and hasn’t acted remotely suspicious so far other than being way too convenient, because the characters aren’t supposed to suspect her of anything, therefore the audience shouldn’t suspect her of anything.
Because that’s just more interesting than her being the disposable love interest.
