Aren't they all going to meet up at this concert? Jack mentioned it to his son, Hurley got Kate, Sayid and Desmond out of jail and said they were going to a concert or something like that? Maybe they all have to be in the same place, like they all had to be on the plane to get back to the island.
Maybe Hurley is now Jacob, cause he can see him since he died and couldn't see anyone who was dead before that...and now he's getting them all together, but breaking those 3 out of jail....
