"No," Robert said. "As a matter of fact, I don't. What I know about you,Mr. Shacklebolt, could be put in a couple of sentences. Former Order member and former headmaster. Friend to members of my family. And, obviously, as the saying goes, the reports of your death are greatly exaggerated. But that's about all. But what I've found is that somehow, powerful people make their way to the Ministry for one reason or another eventually. And the name Kingsley Shacklebolt still commands a great deal of respect. I'm glad you have found people that have helped you at least minimally get what you need, but tell me, how can I help you?"
Khaat had told him, when she joined the staff all that time back, that she had been working for Shacklebolt, and Robert had known how strongly devoted to him she was. She had confided in him how upset she was at the overthrow of Hogwarts and how she had been willing to do whatever it took to try to help Shacklebolt protect himself. As her father, Robert couldnt' exactly say he supported her being willing to die for a man who had apparently now only pretended to be dead. Personally, he questioned what kind of a friend Shacklebolt really was to her if he were willing to do that.
But then again, he also knew his daughter. She could make all sorts of friends with all sorts of people--from her warm and devoted new partner Brian, to cold and ruthless men like Vincent Majere seemed to be--at least in Robert's book. And he respected her for the ability she had to keep all those relationships separate and not compromise any of them. Khaat never believed in sacrificing one friendship for another, and she valued every one of them. Her friendship with Shacklebolt sort of fell into that "I-don't-understand-what-keeps-these-two-together" catagory, but who was he to judge?
