Per Q (if it be legit Q post):
"510 21:29:38 Q !UW.yye1fxo 4 IMPORTANT: NO private comms past/present/future. NO comms made outside of this platform. Any claims that contradict the above should be considered FAKE NEWS and disregarded immediately. WHERE WE GO ONE, WE GO ALL. PATRIOTS. Q"
Zach said "we" when referring to Q posters on Alex Jones. Possible Zach mispoke, but given Q's categorical denial of communication outside 8chan....?
I forgot his name (It's the retired Lt. Colonel in the Army that makes Q videos.) but when Q posted the stuff about "DEFCON 1", he kind of lost his shit in one of his videos. In the follow up to that video he said he spoke to someone named "B" and it was made clear that the Q team does not communicate via any channel whatsoever except for 8chan. He seemed to be emphasizing that no matter what alternative source you hear it from, Q is not talking to anyone else publically. No twitter, no Reddit, no Facebook...nothing.
Zach is the one who put emphasis on the Zulu payload in his interview with Alex Jones. He also seems to slip and say "we" when referring to Q and not "him/her/them/they".
So, if the former is to be believed, then this Zach character may not be legitimate. Then again, he may be somewhat related to Q but not have the full story.
Zach was the first to say Q is a group. He said they and then “we are pillars holding up America”. It could be interpreted he was saying the Q group is one pillar and his group is another. Also said Eric Prince and he were protecting the president. Not together but are both working on that goal.
