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.
