Well she tries her best but she is just too stupid.
I mean she tries to diverge from Canarias original storyline, and she is just too dumb to realize that that there could be many bad endings for her. Going for a divorce is not necesseraly safe.
And I might be wrong, but it feels like she acts like that Cesar and the others are not even real people, just characters in a play. Pisses me off sometimes.
But hey, that's just my 0.02$
