“Dexter” continues to be one of my all-time favorite TV shows. The Season 6 finale aired on Sunday night. If you haven’t seen it, stop reading now.
The season ends with a revelation that has been a long time coming. In the books by Jeff Lindsay, Dexter’s sister finds out that he is a serial killer and she has a hard time dealing with it. We now know that the final two seasons of the TV series will explore that conflict.
The hints were there all season. Debra Morgan struggled with the decision to overlook Deputy Chief Matthews’ indiscretion with a call girl. She told her therapist that she was in love with Dexter, who is her adopted brother and not a blood relative. Now that she has caught Dexter in the act, she will have to find a way to understand the “Code of Harry,” the instructions her late father gave to Dexter.
Perhaps the best part of season 6 was the plot twist in episode 9. That’s when we discover that we’ve been “Sixth-Sensed” by the producers and that Professor Geller, played by Edward James Olmos, has been dead all along. Only Travis Marshall (Colin Hanks) can see him. They kept the secret from most of the cast and crew, as explained in the following video:
