Telemundo has not officially announced the start of production of Season 5 of “El Señor De Los Cielos,” but fans are already eager to find out what happens next. The adventures of Aurelio Casillas (Rafael Amaya) will continue soon and we have a major spoiler for you, El Cabo returns. The character played by Robinson Diaz will come back to the series seeking revenge.

El Cabo was last seen during Season 3 of the narco series. If you remember, Casillas killed his son after he betrayed the drug lord in going after his own family. His life was pardoned, but only so he could suffer with the loss of his son. The news of his return was confirmed by fellow actor Rafa Perrín, who will be working with Díaz on the “La Dama De Negro” play in Colombia. Watch El Cabo’s last moments on “El Señor De Los Cielos” down below and tell us what you think!

Season 4 of the series followed Aurelio Casillas as he falls ill with a serious kidney condition, and only a transplant can save his life. When none of his close relatives prove compatible as donors, he turns to his long list of romantic conquests, hoping that he might have fathered an illegitimate child who could be his salvation.

Complicating Aurelio’s love life, in addition to the mothers of the illegitimate offspring he has left scattered around the world, some of whom answer his summons for a potential donor in the hope of rekindling their past relationships, is a new woman who leads him to question his decision to stay with Esperanza.

She is Amparo Rojas, the sister of Matilde (the former wife of Chacorta, who has since died).  Amparo has come to look after Carlitos, the son of Chacorta and Matilde’s stormy relationship.  She is also a critical care nurse and bargains with Aurelio to help him through the transplant process if he will leave her and her nephew alone.

In the process, Amparo becomes a sort of guardian angel for Aurelio. As the story unfolds, she will have to decide whether or not to give herself body and soul to the drug kingpin.

But just when everything seems to be going Aurelio’s way in both his legal and illegal businesses, when he seems to have triumphed over his political enemies, when he has smoothed over his conflicts with his daughters and is happy in love, a disaster close to home threatens his family stability and forces all of the members of the Casillas clan to choose between Aurelio and Víctor, who is determined to replace his uncle as the greatest criminal in Mexican history.
