Winston's statement about taking Julia's pain for himself is noteworthy here and soon comes back to haunt him. It foreshadows the critical event that eventually takes place between Winston and O'Brien and, ultimately, Winston's allegiance to his own feelings. Even as he says he will take Julia's pain, Winston knows that saying a thing and actually doing it are quite different, a realization that features in what eventually comes to pass between Winston and O'Brien. Winston knows that he loves Julia but does not, at this moment, feel love for her. The beginning of the end is near, and the fact that Winston's love for Julia is transforming into an intellectual exercise rather than a feeling of the heart foreshadows the change that occurs within Winston once O'Brien is through with him.
Winston knows now that the Ministry of Love is the "place where there is no darkness"; indeed, the lights never turn out. Here is another example of previous foreshadowing and irony: Winston certainly took his premonition to mean something much the opposite.
