A man long thought dead by the residents of Sunnydale, or should be dead, after a double murder claimed both him and a Mexican man known as Carca, at the hands of a derenged mass-murderer, Dylan Lee. When the police found him, his left cheek was completely torn out, as well as his liver and large intestine, as reported by nurse Dara Henderson before he was buried.
But Ruben returned. And Ruben was vengeful.
He is reported to have 'taken residence' in an abandoned warehouse not far from The Bronze, where three teenagers were found dead, with exactly the same injuries as those he suffered.
