Q's style and tripcode changed when McMasters was replaced by Bolton. That's kind of a "Yo, Duh," there corsi.

We can speculate about 'who Q is,' recognizing that Q is of necessity a team, the level of sophistication of the comms is it's own Authenticator, who else could produce them?

"Use LOGIC," statistically not possible for it to be anyone else.

We know who The Boss is, his writing style comes through clearly at times, he purposefully doesn't bother to conceal it.

Bolton's writing style comes through likewise, he immediately and clearly put his stamp on it. The busy peeps might be easily confused, but there is zero speculation in the global intel and diplomatic community, who Q is, Bolton couldn't have Authenticated his Comm more clearly if he put his thumbprint on it.

A little more productive to ask the Question "Who could Q not, not be?" including who not only has the Clearance to access that level of intel, who has the Clearance to release that level of intel.

Mil Intel: Q couldn't not not be Bolton, Kelly and a similar cast of characters who sit at the tops of the various chains of command authority required to release the intel. Extraordinary patriots conducting the truly masterful symphony of Executive action we are all witnessing.

I giggle at the speculation, whether or not to trust Q. These people hold our lives in their capable hands, including the nuclear launch codes it's kind of a Silly Question :)

Trust the Plan? It's not like you have another option, who else could you trust? Ten feet from Team T in every direction, the only alternative that exists are seething, roiling vorticies of creatures you can definitely, not not not trust :) :)

A little logic goes a long way, keeping my brow unfurrowed.
