I think Hank Sr, wants the truth, but he does not want it to involve any of his children. He does not want to know, he is afraid it will involve his own kids.Good point. In re: "your information that you have, is it gonna-nevermind,nevermind,nevermind."
He does say the truth has to come out.
Im sure he's not ready for the truth. IMO
He already stated to Tommy that Misty has gotten him into trouble and she is not telling the truth. I think he is now wondering just how far Misty will go to protect Ronald. That is why he wants to know but only wants her to tell her lawyer the truth.
