It looked like the final episode was going to be about Jack dying but keeping the audience guessing right to the end, that was not what the story was about. Could it be my crazy theory that he is not dead be true?

This is US random theory from someone mid series
I do not really believe my crazy theory, but I came up with it because I did not believe in the seemingly perfect relationship of Jack and Rebecca presented. As I thought the final episode of the first series showed cracks in their relationship. A fantastic end to the series seeing the cracks. More reasons to watch the next season to see what happens to Jack and Rebecca and if and how Jack dies. I have enjoyed the variety formats of episodes; different character groups and different combinations of time periods.
