I flipped on the Seacat thing for a min and it annoys me that he's like "we in law enforcement"
I can't see his face, but here we go again, muddying up the victim.
He certainly threatened her enough. I'm not sure this is helping him. I think she stood strong with her decision to divorce and so he killed her. It's interesting that he threatened to release "private" photos of her and I see the parallels with Arias and her recording the phone sex. Two peas in a pod.
