Best known for playing a bad guy on AMC's The Walking Dead, actor Nick Gomez has joined the cast of Dexter Season 8, which debuts June 30th on Showtime.

Its not known when the actor will make his first appearance, or how many episodes he will be appearing in. What is known is that he will be playing the assassin Javier Guzman, nicknamed El Sapo. He becomes increasingly frustrated when Dexter's (Michael C. Hall) sister Debra (Jennifer Carpenter) comes between him and his target. It has not yet been revealed who El Sapo's target is. Could it be Dexter? Or even Deb herself?

Some advice for El Sapo after Dexter Season 7's finale? It would be best if he stayed out of the woman's way. Keen eyed viewers will recognize Nick Gomez as the prison convict that Rick is forced to cleave in the skull early on in The Walking Dead Season 3, when the gang is clearing out their new home inside the state penitentiary.
