last chapter I joked about how little Karina's revenge accomplished; it was symbolic. But now seeing how the petty prince is already plotting his murderous revenge, I would say it accomplished more harm than good. She's less safe now than before they crashed the wedding. Makes it feel doubly unsatisfying. Or perhaps it's an act of delayed gratification.
I'm reminded that the prince not only treated her like crap and exiled her, he sent hunters to murder her in cold blood. He deserves more than a public embarrassment and a stern talking to. His appropriate ending is capital punishment, or ironic death from his own petty schemes.
If I had to guess what the story's reason is for this meaningless revenge, it's that Karina is not supposed to be a proper Villainess. She's a traumatized young girl who has been framed as a villainess, and given every reason to become one in truth. But to become one for real would be the bad ending. Even if she would be 100% justified, it won't fix her trauma. That will only come when she can forgive herself for the past and move on. Which is hopefully her arc moving forward- Her sister might apologize, and the fool prince might die in an avalanche of his own creation, and she realizes that she gets to write her own future.
Some other thoughts- I think the pairing of Eve and Aurora is very interesting. Eve has the perspective of an outsider, while Karina's perspective of Aurora is certainly colored by her traumatic upbringing. Eve will help us see Aurora in a new light. There's a metanarrative going on, where Eve is connecting real life events to a fairy tale, and Reshtoka is trying to make the fairy tale into real life. It should be up to Eve to help everyone separate the myth from reality.
