I have a theory that Oscar only knows the timeline where Inez and Carcel married each other but no other timeline because I feel like he killed himself so that’s why he knew what to do in the next timeline. It doesn’t seem like Inez or Carcel doesn’t recall that timeline because they never killed themselves. However, I also think that Ines especially does not remember that timeline because if they fell in love and got married in that one then she would know in this timeline that she loved him and it wouldn’t come as a revelation to her has she felt that she had a crush on him in another timeline.
