'Dexter' Preview Video: Does a New Doc Know Dex's Secret?

There's a new doctor coming to Miami Metro, and she's about to change everything.

The latest promo for Dexter's upcoming eighth and final season (premiering on June 30) introduces British actress Charlotte Rampling as neuropsychiatrist Dr. Evelyn Vogel, who just happens to be an expert in psychopaths. "Psychopaths are not a mistake of nature," the good doc tells us in a voiceover. "They're a gift."

But the big question is: Could she possibly have figured out Dexter's secret? She sure does seem awfully interested in the blood spatter expert and his knowledge of the Bay Harbor Butcher.

Press play to watch the preview and behind the scenes interviews, then hit the comments below with your thoughts. Will Dr. Vogel be the one to finally take Dexter down? Or will he have to resort to drastic measures to keep her quiet?
