Oh, Biden knows what went down, his demented brain isn't that far gone yet. He also knows he better play the role he has been given to a tee or bad things will happen to him and his crooked ass family. He wants to get even, but he knows he can't. So he will do everything he is told and max out his payoff. I'm ok with that, I enjoy his despair, and his seething anger, he deserves all of that and more for his lifetime of destruction.
