General Discussion

His ex wife Fergie was good at grifting from Epstein while Andrew got the teen sex.

Neither Andrew or Fergie are curious or smart enough to figure out how a crime syndicate operates.

Andrew would be very foolish to open his mouth any further.

The King has removed all of his beloved titles, and taken his large mansion.
But he is still gets support, some money, housing, expenses, and allowed to live on the royal estate
with security.

If he starts talking he will lose that.

He may also face jail time. With no titles he is open now to police investigations.
He is no longer protected.

Also and most importantly Andrew is trying to make sure his two daughters retain their titles and privileges.
And remain working royals. This could be taken away over night if Andrew causes more trouble for the
royal family.
