In case you haven't been following Mariś lately, Cornelio is cheating on Grecia with Emiliano's mother (I've forgotten her name), and together they're plotting to kill Alejandro (Emiliano's father) and, of course, Emiliano himself, because Cornelio blames him for the death of his daughter Coralia (who, as you recall, was married to Emiliano at the time). This scheme is hard to carry out because, as police commissioner, Emiliano is holding Cornelio in jail because Cornelio kidnapped the children of Emiliano and Coralia after Coralia died. So today Grecia came to Emiliano asking him to release Cornelio, not knowing that Cornelio is cheating on her with Emiliano's mother (I wish I could remember her name).
This is a little hard for me to follow, because it's from Venezuela and the accents are different from the Mexican accents I'm used to. Plus, the channel that carries the show recently dropped closed-captioning, which means I don't have the advantage of seeing the words on the screen, pausing every so often, and looking them up in my Spanish-English dictionary. I'd probably stop watching it, but I want to make sure that Emiliano doesn't marry the beautiful but conniving Ambar, since he's really in love with Marķa Eugenia. (That's why he adopted her son, Juan de Dios, not knowing that Juan de Dios is not really her son, but a boy from the neighborhood that she rescued from abusive parents. Well, an abusive mother, really, because his father was Marķa Eugenia's lover before Emiliano arrested him for the murder of Coralia. Which, of course, he didn't commit, but he escaped from jail and is now on the run.)
