First Narnia thought: The redemption arcs!
Holy MOLY the redemption arcs in this series are unparalleled; eat your heart out Darth Vader Prince Zuko Severus Snape William the Bloody. Every single book in the series has a big dang moment where a character realizes they were wrong, and then has to decide what to do next.
Edmund's the first and most famous. He's got outside forces genuinely working against him — a charismatic adult tells him to listen, his only other mentors are equally-lost kids, and he's enchanted by Turkish delight. But the text also makes crystal clear he's got inside forces too: he gets told the queen is wrong, he sees with his own eyes that she's running an authoritarian police state, and he still goes along with her plans. His fatal flaw is not being naïve; it's stubbornness. He walks outside into the snow, realizes he forgot his coat... and refuses to turn around. He initially trusts a charming lady he has every reason to trust, but then he continues trusting her after getting disconfirming evidence. And then he gets confronted with unignorable proof of her evil (the tea party being turned to stone) and he has to own up to his wrongness. He has to apologize. He has to work and struggle and nearly die trying to undo what he did. He changes for the better, he grows up, but he never loses that stubbornness, for all that he gets better at directing it.
Aravis and Caspian are sort of the same, in that they're both raised in privilege, used to not bothering to think about other people. Aravis gets confronted with her casual entitlement, in that her oh-so-clever plan for escape hinged on pinning her crimes on a slave girl who would be punished far more harshly than Aravis herself. It happens in an instant, and Aravis can never take other people's pain for granted again. Caspian gets confronted with his entire culture being one of settler colonialism, and his being the direct beneficiary thereof. It takes almost a decade for him to learn to unwind his parents' and uncle's teachings, and to learn how to use his privilege for good, but learn he does.
Same goes for Jill and Diggory, whom I'll lump together because their fatal flaw is contrarianism and impulsivity. They're both classic cases of fuck around and find out: Jill treats a serious conversation with Eustace as a game and (she thinks) gets him killed in a single careless instant, then Diggory treats everything Polly tries to tell him as a game and ends up indirectly destroying the entire world as a result. And for both of them, that's the start of the story, the note we meet them on. But don't worry; these are coming of age stories, and they'll have to learn to grow in the aftermath of their mistakes.
TBH I think Puzzle is the weakest of the set, but he's the classic case of the person who gets drawn so deep into the cult that they become an active participant in the con. And by the seventh book in the series, we all understand what lesson he's about to learn.
Eustace is my all-time favorite, and he's more timely now than ever: he's the Gifted Kid who has spent his entire life being told by his parents that he's the smartest person in the room, and thus he's never had to do an iota of self-reflection. He uses his big vocabulary and his golden boy reputation to get away with basically anything he wants. Above all else he believes in the system, because so far the system has always worked for him. And then he gets dragged through a painting and into a world with a completely different system, one whose rules he doesn't understand at all. He doesn't adapt, he doesn't listen; he just insists on dragging his existing ideas around as everyone stares at him in puzzlement and disgust. He's every 1950s British anthropologist rolling up to a new culture to show them how it's done, so confident in the superiority of the system he's been raised in and his own mastery of said system that he is genuinely confused why everyone else can't see it too. Eustace also gets the most dramatic corner-knocking-off of anyone: apparently being thrust into a completely new society was too subtle a hint for this kid, so next Aslan thrusts him into a completely new reality for a few weeks (and forces him to shut up and listen in the process).
I love that during and post-dragoning, Eustace not only has to deal with the abominable way he behaved toward everyone around him, but also gets confronted with the terrible reality of Reepicheep's forgiveness. He hasn't yet earned Reepicheep's friendship at the time when Reepicheep chooses to give it, and that's what really humbles him. Even though Eustace learns to listen, learns to turn his cynicism to a measured skepticism, he never loses his core of being a nerd. He stays curious, he stays skeptical, and he manages to make it work for him by getting better at learning. For all the movie's many weaknesses, I love how well Will Poulter conveys Eustace's near-desperation to Get a Good Grade in Adventure, and how hard he tries to understand the rules of Narnia in the hope of getting that grade. It's then so so satisfying to see the turn away from trying to get a grade, toward trying to learn.
