Anons, just wanted to point something out:
If the OIG report is released on June 14th, and Q maintains a blackout until that day, then there will have been ten full days of "darkness" from Q.
I don't think that's the only connotation of the phrase, but if that's how it works out, then keep it in mind. Also, it probably would explain the quiet period before the last post, since the date got moved. I think that's a pretty strong indicator that this report will mark something that is pivotal, something that has been planned for, and something that has big significance to Q's map in general.
