So, we all know Russell Davies likes to throw little tiny clues and then tie it all in the final episode, like he did with Doctor Who. In the first episode, Jack flashes his FBI badge and calls himself Owen Harper. People see this as a cute easter egg, I know I did. A little nod to the earlier seasons. But what if this is Davies little tiny clue? We all know Owen Harper couldn't die, but he also couldn't heal himself either. He was stuck, not dying and not living. What if this whole morphic field business they keep alluding too could be tied into this Company using Owen Harper's unique properties to make everyone else become like that. I don't know, its just a theory I had.
