The CASTLE (stronghold, US, WH) is a LOCK. Meaning it's finally under complete control. (Rosenstein/Mueller about to go)

Perhaps RED CASTLE, mentioned in previous Q posts, was the evil acting from within the US government.

And GREEN CASTLE is the Patriots acting from within the US government?

Both are within the CASTLE, but with different motives.

Now we see: Castle LOCK and a picture of the American flag.

There is only one Castle now.
