Dexter

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.

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.
