Dexter

During Season 8, Angel Batista wasn't always played by David Zayas. His son David Zayas Jr. stands in for his father in some shots, as the two look remarkably alike.

The name of the main character, "Dexter," is also a Latin word meaning "right hand." The implied complement is the Latin for "left hand," "sinister," reflecting his hidden dark side. In 2010 author Jeff Lindsay confirmed at a book signing in Edinburgh that he chose the name Dexter because it was the opposite of "sinister", reflecting the character's surface normality.

In Season 1, Dexter and Rita watch 'Terms of Endearment' (1983), which features John Lithgow. Lithgow would later star in Season 4 as Arthur Mitchell.
