The real Epstein list is in Maxwell’s head, although she may also have electronic documentation stashed somewhere..
My take is that she has now been convinced that she will get a deal of some kind AND live long enough to enjoy it. Something that was not going to happen with the Rats in control. I am mildly surprised she hasn’t been shived before now.
A list could also have been effectively re-constructed by investigators by identifying names in documents, faces in videos, financial transactions, and cell phone records. But who runs any kind of business or operation without having some kind of customer management system, even if but a crude form of one?
