Quote 28
"I betrayed you," she said baldly.
"I betrayed you," he said.
She gave him another quick look of dislike.
"Sometimes," she said, "they threaten you with something you can't stand up to, can't even think about. And then you say, ‘Don't do it to me, do it to somebody else, do it to So-and-so.’ And perhaps you might pretend, afterwards, that it was only a trick and that you just said it to make them stop and didn't really mean it. But that isn't true. At the time when it happens you do mean it. You think there's no other way of saving yourself, and you're quite ready to save yourself that way. You want it to happen to the other person. You don't give a damn what they suffer. All you care about is yourself."
"All you care about is yourself," he echoed.
"And after that, you don't feel the same towards the other person any longer."
"No," he said, "you don't feel the same." (3.6.16-22, Winston and Julia)
For both Winston and Julia, torture is able to chew through the deepest bonds of loyalty.
Quote 29
"What have you done with Julia?" said Winston.
O'Brien smiled again. "She betrayed you, Winston. Immediately-unreservedly. I have seldom seen anyone come over to us so promptly. You would hardly recognize her if you saw her. All her rebelliousness, her deceit, her folly, her dirty-mindedness – everything has been burned out of her. It was a perfect conversion, a textbook case." "You tortured her?" (3.2.32-34)
Upon hearing of Julia’s betrayal, Winston is certain that she was subject to torture, just as he was. Loyalty is easy to breach in the face of torture.
Quote 30
For some reason the telescreen in the living-room was in an unusual position. Instead of being placed, as was normal, in the end wall, where it could command the whole room, it was in the longer wall, opposite the window. To one side of it there was a shallow alcove in which Winston was now sitting, and which, when the flats were built, had probably been intended to hold bookshelves. By sitting in the alcove, and keeping well back, Winston was able to remain outside the range of the telescreen, so far as sight went. He could be heard, of course, but so long as he stayed in his present position he could not be seen. It was partly the unusual geography of the room that had suggested to him the thing that he was now about to do. (1.1.12)
Winston starts a journal of rebellious thoughts as a first step towards his eventual fate at the Ministry of Love.
