Priscilla has been seeking her lost/repressed memories, especially of Teresa, and has been searching to regain her memories, especially that of Teresa, and has been seeking (USING Raki) to find that "memory" which she fears, the one threat to Priscilla's reign over the island, Teresa (which happens to be poor Clare)...
you need to go back and read the 4 special-extra chapters, between ch 73 and ch 74.
we see in them:
*Teresa pwning AO Rosemary... Teresa is truly a Goddess (of power). Priscilla doesn't even compare!
*TRAINEE Clare, being a BAD-ASS!
*Miria's past with Hilda and Ophelia
*Priscilla PWNING Rigardo and Isley with ease! Isley is actually Priscilla's B...H! :D
