Timeline:
Aug 15 - Comey tweets about security clearances.
Aug 16 - In PF 164 Q shows Comey's tweet and quotes snippet of email with "untethered" in it.
adds as a warning:
>Will you stand tall or cower?
>Resist OP will not provide enough public support for cover.
>Smile for the camera.
>Patriots in control.
Q then deletes PF 164 so it doesn't 'exist'.
Aug 19 - Comey's next tweet after Aug 15 does not mention security clearances, talks about the importance of truth and includes "untethered" in it.
Aug 20 - New Q post PF 171 regarding PF 164 and newest Comey tweet
>Do you believe in coincidences?
>Nothing to See Here.
To me this implies that Comey saw Q's post and is now singing a new tune.
