Factual error: In The Beginning while Dexter is on his boat in Miami, you suddenly see mountains in the background, of which there are none in Miami. Also the palms are too high, indicating they are from California. And the worst setting mistake is the Florida tags in front of the cars. Only commercial vehicles have front tags.

Question: The DNA test is a match, but later in the 2-3rd season we discover that Harry (foster father) had an affair with the real mother. Is Harry the real father and takes him but not his brother in because of that or not?
Answer: No, Harry is not the real father. While he did have an affair with Dexter's biological mother (Laura Moser), this was when she was his C.I. Dexter was already born at that point.
