ending to 1984?

I personally didn’t think that Mr. Charrington was part of the thought police but I did think that the Thought police were smarter than to leave a room with no telescreen. I wanted Julia and Winston to work out and go against the party and win with O’Brien’s help but I also thought O’Brien was suspicious in the beginning during the first hate week when Winston and his eyes met. There was also another tip toward showing that O’Brien was suspicious because he knew of an extra thing that normal outer party members didn’t know which was how to turn off the telescreen.
My predictions for the next part of the book are that Julia will be tortured then vaporized, and that there is no brotherhood. I feel that the brotherhood does not exist because O’Brien was Winston’s connection and he was part of the thought police. They also used Goldstein as the focus of Hate week but no one really knows anything about him or has seen him for that matter. The thought police are going to torture Julia until she talks about what she does and who she did it with inside the inner party, and they are going to torture Winston to find out if he told anyone else his thoughts about the parties and about his thoughts to get rid of the party. Then they are both going to be killed.
