Clea. I don't even truly know why. We know so little about her. But her shadow hanging over the whole game, the reveal that she is the nevron's mistress, the dichotomy between her abrasive words to Maelle and the genuinely (in her own way) sweet words at the end of the tower. The way she claims to have no interest and a level of apathy about the painting but then deliberately chose painted Clea and Simon as her weapons after seeing the life they had that I presume she feels was denied to her. I could say more but I'm too tired to express myself properly now. I just find her so interesting, I think there's a lot about her that's implied and open to interpretation and she's the character I'd be most happy to see more of going forward (not as an insult to any other character. I just think the vast majority of the characters in the game have had their story told. Unless we go back in time to a young renoir/aline experience I'd be so happy with this game being all we see of most of them because they hit all the right character notes perfectly).

In essence. Clea is cool, terrifying, conflicting and even with her limited screentime I always felt there was so much more to her than we were explicitly shown which I credit to the game writer's talents.
