Dexter

Dexter's character always wears light-colored shirts to work, but is always in dark colors when he's a "dark passenger".

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.

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.
