I didn’t really care much for Carla’s character because she seemed manipulative and did anything to get her way, I preferred the more genuine characters like Rebeca and Nadia. I really liked Lu during s3 too.
I felt that way at first but then i realized why carla was like that. She doesn’t know how to protect people she care about because she knows her father will do anything to save face even if it means hurting those she loves and cares about. Just my two cents.
