In the book "1984", Winston asks Julia what attracts her to him. What does she answer?

It is in part 2, chapter 2 that Julia and Winston get together alone for the first time and they get to talk freely with one another.  Winston asks Julia why, despite the 10-15 year age difference, she would be attracted to him.  She responds that it was something in his face.  She goes on to tell him that she is good at "spotting people who don't belong", or fit in with the Party and the general attitude of the masses.  She tells Winston that she could tell by looking at him that he was against the Party.  She goes on to severely denigrate the Party even though, she explains, that she goes through the motions of going along with the Party because that's the only way to survive.
