Dexter is confronted by a vengeful Lumen in this clip. She wants to kill all the men that beat her, while Dexter tries to steer her in another direction.
Complete with Spanish sub-titles, this is a clip from the episode "Everything is Illuminated." In it, Deb gets an earful about her plans to pick up the bad guys.
The only real question I have is why in a building full of cops, all supposedly with a keen insight to the human soul, is Doakes the only one who gets the creep from me.
