What do you think is the significance of both Sydney and Nadia working for rogue terrorist cells and then working for the government? How is Vaughn tied? His father was involved in P5 and then the CIA. Did Bill Vaughn also need his son in the CIA in order for this plan to be carried out? How is it that both Irina's daughters and their father's are CIA?
Anyone? This is a perplexing piece of the puzzle.
