WARNING! This article contains SPOILERS for Dexter: Original Sin’s season 1 finale!As a young Angel Batista consoles Harry Morgan about Spencer inDexter: Original Sin’s season 1 finale, he sadly foreshadows one of his own biggest failures and realizations in the main series.Dexter: Original Sinseason 1 confirms that Dexter Morgan wasn’t the first Miami Metro employee who was secretly a killer, with CaptainAaron Spencer being revealed as Jimmy Powell’s murdererand Nicky’s kidnapper. Given how Jimmy’s killer was right under their noses the entire time,Miami Metro’s employees have to contend with the harsh reality that they were blinded by their biases toward their own.
Harry struggles to come to terms with this realization, as he had been friends with Spencer for decades and believed he was a good man and cop. He even tried to deny the idea that Spencer was a child killer to Dexter, but finally owned up to his mistake after Nicky’s rescue inOriginal Sinseason 1’s ending. At one point,Harry asks Batista why he couldn’t see the truth about Spencer, with Batista responding that his judgment was clouded by their long historytogether, a sentiment that eventually applies to himself and Dexter in the main series.

As was the case with Harry and Spencer,Batista wasn’t able to see that Dexter was a killer for the decades that they were friends and colleagues because of their deep shared history. Batista had always known Dexter to be a friendly albeit strange guy, and never would have suspected him to be capable of being a killer like the Bay Harbor Butcher – even when LaGuerta had her suspicions. Additionally, Batista tells Harry that part of the reason he couldn’t see it is that Spencer was a really good liar, a trait that Dexter Morgan also shares.
Dexter: Resurrection’s Harshest Character Reunion Just Got A More Brutal Setup In The Prequel Show
An expected character reunion in the upcoming sequel series Dexter: Resurrection just got even more interesting after Dexter: Original Sin episode 7.
Batista’s judgment was so clouded by their history that he wouldn’t discover Dexter was truly the Bay Harbor Butcher untilDexter: New Blood’s ending, approximately 30 years after his conversation with Harry inOriginal Sin’s season 1 finale. Batista never wanted to believe that Dexter being a secret killer could be true, not just because it meant Dexter betrayed him, but also becauseit meant admitting his judgment and objectivity were flawed. If Batista had ignored their history, he might have apprehended the real Bay Harbor Butcher much sooner.
