how does winston find out the dark haired girls feelings for him?

At work one morning, Winston walks toward the men’s room and notices the dark-haired girl with her arm in a sling. She falls, and when Winston helps her up, she passes him a note that reads “I love you.” Winston tries desperately to figure out the note’s meaning. He has long suspected that the dark-haired girl is a political spy monitoring his behavior, but now she claims to love him. Before Winston can fully comprehend this development, Parsons interrupts him with talk about his preparations for Hate Week. The note from the dark-haired girl makes Winston feel a sudden, powerful desire to live.
