Yep, possibly her fear may have been that Epstein might make some accusations about her or Andrew was her concern, even if it was just about the money “loans”.
However, Epstein had said nothing about any of his friends or connections at that point and in fact never did.
But then why would Sarah Ferguson reel off those scathing personal attacks on Epstein in the interview then if she was frightened about possible retribution! Surely it would have been better to do a quiet declaration of misjudgement to the media, followed by total distancing. Talk about feet first, think later. It’s probably a case of all done “on the fly” at that minute without a moment’s thought for the next minute. One minute he’s her friend, then her worst enemy, then her friend again, but a friend she’s frightened of. Either her advice was terrible, or she took none.
