What happens to Julian?

Julian is a leading member of an anarchist rebel group called The Five Fishes. She's at the center of a love triangle between the so-called Warden of England, the dictator Xan, and his cousin, the story's protagonist, Theo Faron. Julian and Theo, along with other members of the rebel group, go on the run from the authorities. Julian is pregnant, and her unborn baby is a symbol of hope and renewal in a society where chronic infertility is the norm.
However, Xan cynically sees Julian's baby as a chance to consolidate his own power as dictator. He will be able to present himself as the man who finally put an end to England's infertility crisis. But he's unable to put his dastardly plan into effect as Theo kills him. Julian gives birth to a healthy baby boy; the hopes and dreams of millions have finally been fulfilled. Yet at the same time, Julian is deeply troubled by Theo's putting on Xan's Coronation Ring, the symbol of dictatorial power. It seems that there hasn't been any real change, after all; one dictator has simply been replaced by another.
