About to be some turmoil?

With O'briens luxurious flat and ability to turn of the telescreen we see that it is possible for many other high-ranking officials to be supporters of Goldstein and not be found out. Prior to this we had thought that no one could turn telescreens off and that everyone was subject to them 24/7, but this is not the case. This also made me more willing to believe that there is a Brotherhood and possibly a big rebellion in the works. I recognize that it is a small percentage of the people as of right now, but it does seem fairly promising. This is also very similar to the Handmaids Tail with Ofglen telling everything to Offred about "Mayday". We are unsure as to how many there are, but we do know that there is an organized group of citizens that want a change. I can't wait to see how the rest of the book turns out, especially because this last scene has set it up to be really interesting.
