Well.
Of all the loose ends that remain loose, now, it seems to me that one of the biggest ones remains the question of how Beryl got involved with this outfit and the scope of what she was doing for it. We have heard very little about Johnny's review of the diaries. One inference is that she made a bad decision to become entangled at an early stage, and then was stuck, but the weird associations with pedophiles, etc., makes me wonder.
Maybe some day Johnny will be able to move forward with his projects and his life. It apparently remains an open question whether Joseph will be part of that.
