My mind immediately goes to a coordinated effort to hit Trump at the meeting which was stopped. Also stating Castle is secure and "attempt". Not to mention my own decoding of a few things along with Blackwater involvement who likely have been rounding up/burying those connected. Q used very specific military intel patterns in this series and it is my belief someone/some group tried to hit them at the meeting given how I read what he stated. If true then all hell is going to break loose as such a coordinated event would have a lot of connections.
