True Nemesis for Dexter, not Trinity he did nothing so bad like Oliver did. This guy deserves much more edits, much more love, he was damn amazing villain.
When you realize that because he ditched Barney, he became a serial killer, that's what he did when he didn't take care of him. Hopefully, Barney will never find out.
Miguel was not as smart as Dexter, but he was great at manipulation sadly he lost as he was not able to anticipate Dexter's deception. This is displayed further in the books, however he was not as intelligent and Dexter, Brian, Trinity, and many other characters. This comment is incorrect and the writer is misinformed. I recommend reading the books as they bring a lot of insight into various characters although at some points it feels like a whole new story. Dexter's philosophy and new perspective introduced in season 3 is what led to him becoming so easy to deceive. Side Note: IN this universe, not only is Dexter The smartest Killer in Miami, but the most intelligent and Notorious serial killer ever.
