We have:
Nathalie vs Francine: Catfight
The discussion between Francine and Nathalie showed the eternal rivalry. Stunning in their bikinis, both moved away from the party, seeking some privacy. The challenge had been launched: fight to the finish, without rules. They could pull hair, bite, punch and kick... ANYTHING GOES!
JoAnn vs Brook: Fistfight
Meanwhile, JoAnn and Brook argued over their previous duel. Nothing seemed sealed, with all their differences grow after the previous fight. They hated each other, and their rivalry could only be solved with a fist fight: no gloves, with bare fists... and all the enemy's body to PUNCH!
FIGHT!
