My concept for how it will go down:
1) Media transmits "Q makes insane claims X Y Z" (normies laugh at what they believe are crazy people, anons smile)
2) Some oversight/law entity (likely Justice Department) releases iron-clad evidence of cabal doing something X that is inconceivably bad and seemingly implausible (while for optics POTUS keeps distant, this is an action taken by some independent non-partisan official)
3) Public goes "WTF X???" and then "hey Q was talking about that" … and suddenly (without even any official announcement about Q being needed) all the other things Q has been talking about gains instant plausibility (with the media's disinfo campaign against Q having helpfully seeded the normies with what they need to know, ready to unlock into belief with the right evidence)
4) POTUS acknowledges Q (when by this time everyone knows it must all be true)
