Come ON, anon. This is not the first time. Maybe someone was getting too close to exposing something else with a dig and Q wasn't ready for the reveal. Maybe Q needed to rattle some cages for reasons not apparent to anons. Maybe Q needed to distract from something else, or maybe he needed to refocus on this for reasons not apparent to us.
He has done this exact thing multiple times. It doesn't even matter. We know that nothing can stop what is coming. The wheels continue to turn whether we can see them turning or not.
