It was quite early in the game when everyone knew that knowledge, maybe near the middle, all the guardians and even Tidus knew of Sin returning, and that the Calm would last for ten years after Sin's been vanquished.

The whole of the people in Spira were aware of Sin returning, how could you forget that?
