It really was the peak of what i remember from the show. It does having an intriguing consequence that Dexter starts to be concerned his son will have the same reaction that Dexter did to witnessing his mother’s death and starts monitoring him for signs. If I remember correctly, he’s both concerned that his son will be cursed to be like him, but also excited by the idea of having a bond and mentorship with him through it. But even that gets a bit hamfisted as I recall and ultimately goes nowhere. The show really whimpered out in later seasons.
