Florence knew very well that the Howards were now facing an unfavorable situation.
The eight top families of DC had been around for a long time and had held power for years.
The reason there hadn't been any large-scale battles between the eight families and that they could maintain a delicate balance was due to the mutual control.
Once any family took the lead in launching a large-scale attack on another, they would very likely end up in a lose-lose situation and eventually be divided up by the other major families.
Thus, there had never been any large-scale conflicts among the eight top families over the years, though there had been some minor squabbles.
But things are different now. Once the Piers and the Williams really united and targeted the Howards, the Howards wouldn't stand a chance at winning. They would eventually end up having their assets seized and split among the Williams and the Piers!
