The beginning of the end kicks off this Sunday for television's most popular serial killer.

On the Dexter Season 8 premiere, we'll fast forward six months from the traumatic events that concluded Season 7, with Deb spiraling out of control... the gang gathering in honor of LaGuerta... and Dexter cradling Harrison with a very bloody hand.

Viewers will also be introduced to Dr. Evelyn Vogel on the episode, a mysterious psychopath profiler with a strong interest in a certain blood splatter analyst. Click through photos from the opener below and watch this Dexter sneak peek to get an idea of how dangerous the doctor could be:
