Continuity mistake: Quinn brings Deb into the interrogation room and puts his coffee cup down about 6-8 inches from the end of the table. He then moves his chair and begins to talk to Deb without touching the coffee. In the next several shots the cup has moved to the middle of the desk, and the amount of steam rising from the cup keeps increasing as it sits there.

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.
