Narrative momentum and character agency
We all remember the ending of Avatar: The Last Airbender.
Specifically, the final battle against Ozai.
Aang has been terrified of the confrontation and has decided with his friends, off-screen, to just wait until after Sozin's Comet passes to actually try and fight Ozai. Zuko is utterly taken aback by this, revealing to Aang that Ozai is going to burn down the Earth Kingdom under the power of the comet and if they wait too long, the world will be a wasteland.
Aang reveals that his fear is not necessarily that he cannot defeat Ozai, but that he doesn't know how to defeat him whout killing him, which Zuko further berates him for. Ozai must be stopped, and if that involved ending him, then so be it.
That night, Aang sleepwalks onto the back of a Lion-Turtle, who imparts on him the knowledge of energybending, which Aang ultimately uses in order to cut off Ozai's bending, rendering him helpless without having to kill him.
A lot of people have a problem with this.
Energybending, came out of nowhere. Lion-Turtles have had some imagery sprinkles through the story, but aren't even named, let alone have their importance mentioned. And of course, it feels like a deus ex machina-- we can't have our sweet innocent boy Aang actually kill somebody, so we made up a third option that leaves his hands clean!
And that's fair.
But I think the real problem with the ending isn't actually energybending, or the lack of build-up. Would it be better if there had been rumors of a 'fifth way of bending'? Of course. Would it be better if we learned about lion-turtles at any point? Absolutely. But the actual problem with the ending--
--is that Aang sleepwalks into the solution.
This is the part that really breaks the narrative flow. Aang becomes completely passive. He literally goes to sleep and wanders off to the back of a lion-turtle, which then gives him the knowledge of energybending. And what kills me is that this is extremely easy to correct: have Aang meditate instead of sleep.
It is now his choices that directly lead to finding the lion-turtles. It is his decisions that bring him to the solution. Aang has agency.
This is actually a very common problem in a lot of modern storytelling-- a strange aversion to having the characters actually make active choices and move the story forward of their own will and power. Characters do things because somebody else tells them to; problems resolve because somebody else intervenes.
In extreme situations it getes so bad that removing the main character effectively has no impact on how the plot resolves; the book Tekwar resolves every conflict by havign somebody else save the lead character, up to and including having the final battle resolve itself by a strike force led by a character who hasn't shown up since the first quarter of the story burst through the wall and kill the villain in a hail of gunfire. This isn't evena case where Jake Cardigan gets kudos for leading them to Sonny Hokori-- this strike force was conducting a completely independent investigation and just happened to show up at the same time. Every single occurrence in this book is only made worse by other characters having to save Jake from assassination attempts, which itself has no impact on the broader story because the characters exist in scene vacuums.
This occurred to me mostly recently with the discourse surrounding the finale of The Amazing Digital Circus and a kind of ennui that a lot of people seem to be experiencing about how the show actually wrapped up, and part of the problem is in that lack of narrative momentum and character agency. The central promise of the first episode is that Pomni is attempting to find an exit, and certainly will try to escape the circus. This plot motivation is then dropped until episode 7, where it only comes back because an external character introduced the idea. Nobody in the circus seems particularly interested in escape, which might make sense with the other characters (who have been here so long they give up) but doesn't really make sense with Pomni's expressed curiosity.
And then we get to the finale itself, where the revelation that the cast were all brain scans is dropped out of nowhere because Kinger spontaneously remembers it and the characters just... instantly accept it and we just move on.
The issue that this creates structurally is that the characters, all through the show, have more or less contributed nothing to the overall story through their own actions. Episode 8 is the first time they really take things into their own hands and it's actually quite exciting and tense (even if they only did so because they were spurred by an external actor). In Episode 9, Pomni does actively choose to engage with Jax, but once she's in his mind-space she breaks through to his 'real' psyche by... standing in a room while the other Jax's disappear and one of them gives her a key. What did she do to facilitate this? Nothing.
To go back to the initial revelation that the cast are all brain scan copies-- again, it just kind of happens. Kinger remembers it with no prompting, the character accept it without any meaningful pushback. Cain comes back entirely on his own, and brings with him the knowledge of their original selves, once again meaning the characters don't really have to do anything involving the broader plot (although they did at least find a way to resolve the Jaxstraction issue without outside interference).
It can be hard to feel exactly what's wrong in the moment, because the emotions are hitting the right keys and usually overriding the questions you might be asking, but it can create a strange sense of something feeling unfulfilling and unsatisfying, because in narrative terms it feels completely random. This is happening because the author needed it to happen and the characters are largely just there to experience it.
The resolution to this, in TADC's case, would be to have the characters find out this information on their own. The solution is a bit more complicated than the Avatar example, but it would have made sense to have the characters, in the wake of Cain's apparent death, investigate his office and find the brain scans there. We get the same revelation, we have a better chance to let it breathe, maybe we go whole-hog and have them dive into the void to try and restore Cain, which would make his own existential crisis about his relationship with the humans even more complicated ("They tried to kill me. They tried to save me. Humans are CRAY-zy!"
(I acknowledge here it's a little unfair to say 'you should've done this!' to a complete story-- it's much easier to offer a revision than it is to create something whole cloth. That said, it's also an important exercise to understand why something didn't work for you and if there were ways to improve it, as if you find yourself in a similar situation you've learned from a prior example. It's just as important to understand why something isn't working for you as it is to understand why something is.)
To provide that example, in fact, in my own writing I had an early situation where a character was introduced to the magic system. The original way I did this was by having another character provide them with the medium and nudge them in the correct direction, which was fine, but then it naturally led to that second character guiding them further on and I realized quickly that my two leads had accomplished nothing on their own within the first few chapters, and were being set up to more or less be led by the nose going forward.
So I went back, removed that intervention, and had my lead making decisions that got her to shelter, and got her to the magic, and allowed her to understand what she was seeing and use it, and it completely changed how I as a writer interpreted her character-- no longer a passive victim being given tools to survive, but an active agent whose resilience became her defining feature.
This is not the elimination of all external intervention: other characters exist in the world and can also have their own agency. This is also not to eliminate coincidence-- even in real life we encounter coincidence. But a character who makes their own luck, through a series of decisions that lead them to that coincidence, is far different than one who stumbles on solutions and intervention by standing in the right place at the right time. This is not to say a protagonist cannot be thrown into the plot because of external forces, either-- Refusing the Call is a staple of the Hero's Journey and the Reluctant Hero is a personal favorite of mine.
This is also not to say that passive protagonists are inherently bad. You can absolutely have a compelling story with a protagonist who is meant to be watching other characters (The Great Gatsby is not told from Gatsby's perspective, after all). But in traditional storytelling your protagonist is usually the one who's supposed to be experiencing and impacting the plot.
When you're writing a plot beat and find an external actor is more responsible for the forward momentum of a scene, ask yourself-- would this be more powerful if my lead were the one making this decision, or intervening in this way? Do I need an external actor to guide this scene? Sometimes you do! Sometimes this is the moment to Big Damn Heroes are helping your outmatched, scrappy crew. Sometimes this is the moment in the thriller when somebody must burst through the door.
But oftentimes, especially when resolving a conflict, an external actor is not a relief for the protagonist being saved. It is a loss of opportunity, a failure of agency, and a moment where your lead has been undercut and your narrative has told the audience-- this character doesn't really need to be here, and somebody else will save them.
