In the Season 4 Episode 12 “The Getaway” finale, the police close in on the Trinity Killer, who cautions Dexter to keep away. But Dexter is willing to do whatever he can to get his man, legal or not. Meanwhile, LaGuerta and Batista must answer for their breach of ethics; and Debra becomes privy to something she’s not sure she wanted to know.

The writers also had an alternative ending for the finale, which was not chosen at the end. “While Dexter was packing to leave, he saw on the television that a child murderer had just escaped from prison. Either escaped or fallen thru the cracks. So he’s thinking, ‘Do I join Rita on vacation or do I…’ and then he looks towards the camera and he has this big decision.” Uh Dexter needs an acne lotion perhaps.

Yeah ! the next season, I can wait for it either. I think its a season were dexter has to be a lonely father and see his son grow with the terror he himself had faced. Its time for Dexter to take on the role of his father and go through the pain of raising another serial killer, one of the followers of Dexter said.
