In Book 2, Chapter 10 of 1984, Julia awakens and she wonders why the stove's gone out. They're in their little room and she'd made sure that the oil had been full before going to sleep. It has gotten cold.
She can't make coffee. Winston goes to the window and listens to the woman singing in the yard. He thinks of her as fat and ugly, but it also strikes him that she's beautiful. Winston realizes that people all over the world are the same. We are the dead, he says aloud.
And Julia repeats his words. But from behind them, they hear the words again, this time spoken by the thought police. They are caught.
The woman in the yard stops singing, and there's a yell of pain. Men in black uniforms stampede into the room. As ordered, Winston and Julia turn back to back and hear trampling.
Their paperweight is smashed to pieces. Julia is punched in the chest and lands on the floor. She's carried out of the room. Mr. Charrington walks in, much changed.
Turns out he's a member of the Thought Police. He has trapped Winston and Julia with the illusion of privacy. Now in this chapter, Orwell foreshadows Winston and Julia's arrest when there's no oil in the stove. When the Thought Police arrive, they repeat everything Winston says. Winston's private space has been exposed as a party space.
The extent of Winston's thought crime is known to the party. In the first half of the chapter, the earlier pessimism turns into a kind of optimism. Despite the fact that Goldstein's book says inequality will always exist, Winston remains hopeful. He reflects on the woman singing outside the window and considers symbols of freedom and beauty. While she sings, the party does not.
Proles will rebel if enough stay conscious and believe that two plus two equals four. Mr. Charrington has seemed like an innocent prole up to this point. When he enters the room, all he has to do is speak, and the uniformed men are quieted.
He's no longer wearing his spectacles, he's lost his Cockney accent, and he looks completely different. Mr. Charrington has deceived Winston from the start. In the world of 1984, no one can be trusted, and nothing is as it seems.
