This really has me wondering. I for one was not expecting anything earth shattering in terms of Cassey's guilt from Tracy, Rob, LP, et al as I pretty much assumed she would be on her best behavior and following all directives from her attorney at that point. I still am dubious as to why we are seeing this action now, particularly if there is any question to the authenticity of the original agreement and whether there was an intentional attempt to deceive the court to determine the outcome of a ruling about testimony in this case.
I am rambling now, apologies.
Sounds to me, if TP is correct - you have it figured out exactly right.
