It's difficult to say when exactly Comey was turned from DARK to LIGHT, but the most likely wakeup moment for JC occured on 16-Aug-2018 (see attached James Comey Untethered graphic).
If you're not following me, let's review Q post 1931. Embedded we find Q post 1912 in which Q posts a classified and incriminating email from JC that includes the word "untethered". In response JC shits out a Tweet 3 days later (see graphic decode) in which JC proposes a plea deal with reduced sentencing for his complete cooperation with Q and the DOJ. Ever since that day Comey has been shitting out tweets and making publicly bizarre statements. His tweets are layered several courses deep with hidden comms, suicidal jesters and philosophical horseshit.
Comey is was and will always be total SCUM, thru and thru. But like it or not he's OUR GUY now. The question we have to ask ourselves now is: What the hell are we going to do with this guy? My best guess is that Q/POTUS are planning to roll out dozens of these formerly Deep State scum in a public spectacle of one carpet bomb after another having these scum truthfully testify against their former Deep State bosses thereby red-pilling and waking up as many brain-dead normies and lefties as possible. It makes sense to me that this is THE PLAN so as to save as many innocent lives as possible when the HRC and BHO Deep State holdouts are pushing civil unrest, riots and insurrection.
