Input: Dexter Morgan:  The victim led a quiet life . No enemies .
Dr. Evelyn Vogel: Serial killers do n't have enemies . Everyone 's a potential victim .
Dexter Morgan: Well , if you need anything else , just pick up the phone . Anybody at the lab can help you .
Dr. Evelyn Vogel: I was interested to have your take on this case .
Dexter Morgan: Me ? Why ? I 'm the blood guy .
Dr. Evelyn Vogel: " The blood guy . " How did you end up here ?
Dexter Morgan: My dad was a cop . He kinda steered me away from that . This seemed like a better fit .
Dr. Evelyn Vogel: I
Dr. Evelyn Vogel: was drawn to forensics , too , but chose to focus on neuroscience . Psychopaths . We both chose murder . Maybe we 're both a little crazy .
Dexter Morgan: Maybe .
Dr. Evelyn Vogel: Mad scientists , trained to look at this as a biological mass , a body part . Yet , somehow , from all those firings of neurons , something ... intangible emerges . Emotions . Trust , morality , love . Unless you 're a psychopath . But even then , belief systems emerge ... as with the ... Bay Harbor Butcher . What was he like ?
Dexter Morgan: Who ?
Dr. Evelyn Vogel: The Bay Harbor Butcher . James Doakes . I- if I 'm not mistaken , he worked with you here in Miami Metro .
Dexter Morgan: He was angry . Had a short fuse .
Dr. Evelyn Vogel: Well , that does n't sound right to me . As a psychopath , he would be disassociated with his feelings , not quick to anger .
Dexter Morgan: Maybe he was n't a psychopath .
Dr. Evelyn Vogel: Oh , yes , the Bay Harbor Butcher was definitely a psychopath . He 'd have to be to masquerade the way he did . But he was an odd _ one _ , that 's for sure .
Dexter Morgan: You 're the expert .
Dr. Evelyn Vogel: Just the way he picked his victims - persons who , on the whole , had some sort of criminal background - speaks to a ... strong belief system , almost as if he operated with some sort of ... moral guidelines .
Dexter Morgan: " Guidelines " .
Dr. Evelyn Vogel: Yeah , clearly it was n't a moral choice , as psychopaths have no conscience . So , why else would he kill that way ?
Dexter Morgan: So he could ... get away with it as long as he did ? People are less likely to miss criminals when they disappear . Doakes was Special Ops ; maybe he picked it up from there .
Dr. Evelyn Vogel: Maybe he did . Makes an interesting case study . I wish I could have interviewed him .
Dexter Morgan: Sorry .
Dr. Evelyn Vogel: I look forward to working with you , Dexter Morgan .
