Dexter

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.

Dexter has killed about 117 people according to the Dexter Wiki. He had 45 blood slides in his first box before it was destroyed and now has about 43 slides in his new box. There were also 20 or so victims from whom he didn't collect blood.
