1984 Brotherhood

When Winston meets with O'Brien and he takes Julia they discuss on how the Brotherhood works and what they expected them to do. O'Brien explained that he himself did not know how many people were among the group just a specified group and that will also happen to Winston. They also talk about how Emmanuel Goldstein was their leader and savior yet Winston grew up in the hate of Goldstein. Each side is different one against the past and freedom the other for freedom and the true history. Together Julia and Winston agree to join but are unwilling to separate from each other. Among this discussion does O'Brien truly acknowledge Winston and Julia as members or does he plan to just use them as pawns? Since he barely saw Julia during the conversation, yet among that completely disregarded her from the beginning. What is the true connection between Winston and O'Brien, is it truly the eyes that told the truth between them or something else?
