Just catching up from last night.
I can confirm that General Flynn changed his Twitter background between the night of March 5th & the morning of March 6th.
See time date stamp on my tweet (as you can see I found the change "significant" at the time).
I was on Flynn's Twitter on the night of March 5th & by the next morning upon revisiting his page the background was changed to the tidal wave.
As you can see, Q posted "Watch the Water" at 5:18 am on March 6th. When I checked Flynn's page before 9am that same day, Flynn had made the change.
His selection of the tidal wave could have been no more than 8 hours before the Q post & less than 4 hours after.
I often hide messages in my banners so I keep a close eye on others who seem to do the same.
I hope this helps. Looks like we've got smooth sailing ahead!!
