Exclusive: Dexter Adds New Blood in Season 8 – Does It Signal the Beginning of the End for Dex?

The countdown to Dexter‘s endgame has begun.

The Showtime thriller will introduce two major recurring characters in its upcoming eighth and likely final season — and both could spell trouble for Dex and Deb.

First up is Dr. Evelyn Vogel, a formidable and whip smart neuro-psychiatrist in her late 50s who assists the law in profiling criminals (like, perhaps, the one who murdered LaGuerta?).

The show is also on the hunt for a 40ish actor to play Jacob Elroy, a handsome and straightforward former cop who now owns his own private eye business. Our guess: Angel (or maybe Tom?) hires him to find out who killed his ex-wife.

Do you agree/disagree with our theories? Got casting suggestions? Do you think Dexter should call it quits after Season 8? Sound off below!
