Who is this "Deep Throat" character? I mean, we don't know anything about him. What his name is, what he does...
He's in a delicate position. He has access to information and indiscretion could expose him.
You don't know that this isn't just a game with him. He's toying with you. Rationing out the facts.
You think he does it because he gets off on it?
No. I think he does it because you do.
