For once, Harold's and Root's goals align. Still they take their own paths. Vigilance, a rouge government attached cabal, is revealed. Whatever the endgame of Vigilance really is The Machine will work to it's own end is clear. Yet, Vigilance survives to surface? One can't help but be intrigued.
This was a consummate episode as it blended so many nefarious elements: HR, The Machine, Root, and a number of the week with ties to a new threat going by the name of "Vigilance". Vigilance is particularly black as being within the government's already black ops. Can the stew get any richer?
It all comes to a mass when Harold, who now holds Root prisoner, asks her the question: "how can you be sure that you are exactly where The Machine wants you to be"? One must think that both, Harold and Root, are under The Machine's command.
