Goes back to at least February (Trump referring to McCain), and could also be (in part) tit-for-tat as McCain has also done the "I won't say his name" thing when referring to Trump.
I'm not sure what "proving Q" actually is, but can think of other ways Q and Trump could grow close in use of terms. For analytical sake only, assume Q is a larp working out of his basement. Trump reads Q and is highly entertained by it, so he pretends Q is an administration confidant, and adopts or reinforces the myth with carefully chosen remarks, tweets, etc.
I'm not saying that's what is going on, and earlier this morning said I believe Q is an administration confidant. My point with the example is just that whatever Q and Trump appear to have in common, can be explained by more than one hypothetical mechanism.
True. But to nitpick.
Q was saying "we don't say his name" long before it became noticeable that Trump did.
I'm convinced Trump got that from his people. Of which the Q team is a part of.
