So, we watched the Dexter series (2?) when he ends up entangled with scary arson lady and nearly gets discovered. We have just finished watching the series (1?) where the ice truck killer turns out to be his brother (and incidently I had to stay up for another hour watching fluffy telly until the whole small child in scene of massacre started to fade). In this early series he does a DNA test which has his real dad as some chap who has just died that his foster dad didnt tell him about. I was sure in the subsequent series he finds out that his foster dad was having an affair with his real mum and so he was in fact harry's son. Did I get that wrong?
I cast this question out into the mumsnet ether in the confident hope that it is all-knowing..
