Desmond realized they were in perg but so did eloise. Charlie was getting there, Hurley probably knew and didn't need Desmond. (we never saw Hurley find out. and Im thinking if he was the new Jacob, that he would have been the one to "show" everyone.) I still thought Desmond was going to be much more important than he wound up being. but im not trying to knit pick. i was just trying to work it all out in my head after the finale. Not too sure how I felt about Jack never having a son. that one hurt. I felt a little tricked. but all in all, i liked it.
