Curate, connect, and discover
I think at this point a fight between ylfa and La Bête is coming and I'm so excited for it. These two are the same, while also being completely different.
Here are my thoughts
Ylfa did not want to eat the wolf, but had to to survive. While la Bête ate her captor with absolute delight.
The moment when those two spoke in the library ylfa realized that she faced someone who truly embraced all aspects of being a beast, especially the gruesome parts and she thrives on her willingness to exact violence. Which makes sense in a way since la Bête took the power from her captor to become something mightier, someone who isn't helpless. La Bête isn‘t evil, she is being herself, truly every living out every part of her soul.
The same can‘t be said for our best girl.
Ylfa is afraid of cruelty, she wants to be kind and seen as such. I think seeing someone is the same as her but who doesn't hold the same fears as her scares her a bit (Especially knowing that la Bête might use violence on her and would have no hesitation about it probably).
I do hope tho that that she is "redeemable" cuz there is big hairy bloodthirsty sister vibes here.
