So now the saint is our villain ? I couldn't get it exactly

I think the master of the tower possessed her but she is probably fighting back and he is not in full control that's why in Rene's dream it looked so creepy

Just a theory though

Oh well ..... I don't think a broken master of a shitty tower who has lost once can beat her again in that tiny body , the only interference is for Rene to not kill the body cause she wants Liam back
