After she called him a vulture he fired back. After that not a peep out of him about any of this.
Is that really all it takes to scare him off?
I speculate that he is not scared, he is just disgusted with her and has washed his hands of having anything to do with her. He might be interested in any relevant information regarding Art, but I think he is professional enough to not want to dirty his hands by having any unnecessary contact with HW.
He's well known, well respected, and is smart to have nothing to do with her. Imho.
