My 2 cents from when watching it unfold when it did.
Military snatched Epstein from the prison, drugged and bagged him, flew his ass to Ramstein AFB Germany (we watched the flight).
Downloaded the information they wanted directly from his brain (fMRI).
Once they got what they needed, he was no longer of service; probably killed him or let him commit suicide.
With info in hand, military was able to get to Epstein Island a day before the FBI.
Remember all the "811 call before you dig stuff"?
Got the dirty secret black book stuff [they] thought would never be found.
FBI unable to retrieve and black hole this info.
Ghislaine generally surprised we have all the intel, cuts a deal.
Good guys have been using this intel - somehow - to leverage the DS into damaging themselves.
