A couple of disconnected but potentially big theories.
a) Someone showed Clinton reading White Squall on the Delta Flight, duno if real but Q has mentioned white squall in recent past. Would be another Q proof since he mentioned it before Hill decided to read it.
b) The raid on Black Forrest. Could there have been a massive gold vault there? Seized Asset based on Dopey's Tips. 2 Plane loads of Airborne is a lot.
