I don't know Mr. J. , There is 3,000 page FBI report that was sent to the defense to open this door. While we aren't privy too everything in it, let's see if AJ can bring some light or if "that so called door can be opened."
All the exculpatory stuff in there AJ had already and used for trial 1.
There have been some small differences. e.g he chose to ask Jen about her FBI interview whereas he did not do so last time.
I don't think there is any game changer in there.
