I don't know if this question has been answered before, but it is really bothering me! I just started watching Dexter from the beginning a few weeks ago. Now I'm on season 4 and the Trinity Killer is introduced. Is he not the same guy who is Rita's father? I swear I thought that he met Dexter (maybe, not sure) but I do know for sure that Rita sat and had lunch with him during one episode. Perhaps this will get answered by the end of the season...maybe Dexter doesn't know his connection to Rita because he never met him? But I did some googling and didn't come up with him being Rita's father. Did they just use John Lithgow twice in the series and think no one would notice? Or did I absolutely miss something?
