From The Grey House:
Due to the shift of power, Vincent revised his plan and told his friends to scatter until they were needed. He kept a small amount of people in San Francisco and around the Bay Area to make sure he was kept safe. As his lands were not in the city, only his businesses, Vincent did not have to worry about Edwin trying to kill him. Also, Edwin took a certain amount of pleasure in sparing verbally with Vincent about their mutual hatred of each other. The younger vampire brought up the attempt on Christopher’s life almost every time Vincent was in earshot. He thought it was funny that Vincent could not take over the city.
