The Unbearable Burden of Greatness
Yosef speaks about God more than any other character in Bereshit. Yosef has absolute confidence that he can interpret the dreams he is told. Why would Pharoah care that there's a prisoner who claims he's innocent, he's just another prisoner!
When Yosef and his brothers meet he is practically begging them to recognize him but they can't envision him being anything more than a slave. Everything Yosef says and does is deliberate (e.g. he sends all of them back except one, like the story of the sale),
