Why does Jack and Juliet have a son?
Jack and Juliet are both doctors or in other words a man or woman of science. Men\Women of Science have a harder time believing in things based upon faith and have a harder time “letting go”. Because of this difficulty it is harder for them to move on from Purgatory/Dream World/Alternative Reality Oceanic Lands World. Jack and Juliet create a son it this alternative reality because it gives them stronger ties to the imaginary world and thus are rooted in believing what they are experiencing is real, even though they are dead. Please let me know what you think and I was also like to see if there is anything else that can back up this theory. Thank you.
