Dr. Vogel appears on Dexter’s door step and proceeds to show him a video tape she has that explains how she has the ability to know everything about him and where he came from. He finds out that it is in fact Dr. Vogel who had instructed Harry, Dexter’s father, towards teaching Dexter to funnel his murderous passion towards people who actually deserve it. She had developed the code, therefore developing Dexter. He does not look at her with fondness however, due to the fact that he has begun to hate his murderous urges at this stage and the lasting effect they have had on Debra. Vogel informs Dexter that the new murder in Miami is possibly one of her bygone patients. He thinks this because the murderer is putting samples of his victims brains in jars and leaving them on her doorstep. She feels deeply troubled by this and asks Dexter to take care of him for her. Dexter candidly refuses however. The Brain Surgeon in the meantime kills another victim with the help of a fall guy, and dumps the body. This time though, a fingerprint has been left at the crime scene. Unfortunately, this fingerprint in question belongs to Sussman, who was butchered by the Brain Surgeon and later framed for the crimes the Surgeon has committed. The Brain Surgeon then breaks into Vogel’s home and leaves her a DVD, containing the graphic and horrifying footage of him murdering Welks and Sussman. Both Dexter and Vogel come to the realization that this is truly happening all the while trying to keep it from Metro Police.
