Bachelorette groups would usually consist of up to 12 girls that leave their birth groups. It can sometimes be more then 12! The result is that they would remain within the bachelorette groups until either one or all of the girls encounter another: like sometimes another bachelorette group, matriarch group, harem or simply a patriarch group. They take turns challenging the lead girl of a harem or matriarch group. It would be until the either one wins. If one loses, the winner takes place.
