Soooo... you know the part in Words of Radiance when Wit visits Kaladin in prison? This is what is said:
He hummed softly to himself and nodded. “Perfect pitch,” Wit said, “makes this all so much easier than it once was. . . .”
Sooooo I was doing research, on the Heightening, and if you reach the second heightening, you have the ability of perfect pitch.
Question/theory: Wit has Breath. At least 200 of them, as that is what grants the ability of perfect pitch. And obviously, Wit didn't have it before, "than it once was...." is what was said. So does he? Does Hoid have at least the second heightening in breath?
But yeah! What do you think?
