I know I can't be the only one who agrees with this. Just to point out some of facts and my thoughts.
It seems that Jack has completely become a man of Faith. He was willing to let himself die (via dynamite) because he knew that nothing would happen. The Jack from the first few seasons would have NEVER tried such a daring stunt. I believe Team Jacob found there leader.
It seems that Richard has a will to live again after seeing Jack's faith. Not to mention that it was pretty cool that they explained why Richard never ages.
Ben seems to be on the good team and is finally getting redeemed for his evilness from the earlier seasons.
I wonder do you think Widmore will be with there team and that Ben and him will cooperate, or perhaps Widmore will be for MIB's team.
I could talk a lot more about this episode but I want to see what you all have to say about it. And I will continue to comment on here after hearing a few more thoughts.
