if both women were face to face, chest to chest, neither willing to back down, I believe that you had the perfect opportunity to initiate a catfight with a little encouragement for them to settle their differences physically. You could have also suggested an arm wrestling or locked fingers test of strength between the two, that could also have escalated into an all out catfight. Seems the two don't like each other and eventually will have another confrontation. They eventually will fight with a little encouragement and remarks on your end. good luck.
