If we set ‘Fall Out’ to one side for the moment. While considering what Number 2 told Number 1 in ‘Once Upon A Time, “I was a good man, I am a good man. But if you get him he will be better.” This possibly meaning, that if they “get” Number 6, that they manage to get him to accept The Village and his place in its society, then he will be Number 2. That all Number 2’s are interim Number 2’s, until they found a prospective permanent Number 2 in Number 6!
Be seeing you
