I have a feeling before that the original raeli and original beatrice swap their soul so now the og raeli is now in beatrice's body and the og beatrice is now the raeliana. i saw a comment on instagram and saud that this is true. the raeliana right now is the real/original beatrice but since they swapped soul, they need to kill either one of them in order for their soul to be completely adapt on their body. i saw a translations on instagram that iona tells noah to kill the brown hair (raeli) because his destiny is beatrice and if he did kill raeli, everything will be over. however, the original beatrice is now on the body of raeliana, which is now the raeliana, that means noah is with his real destiny but bcos of the soul swapped, everything become a mess and the original raeliana is now beatrice, which should be the one they should kill. if there's someone that needs to die,it should be the original raeli which is now beatrice because she was the one who started all of it because she doesn't want to die early. also, iona told raeli that she will help her regain her past memories, which is the memories of the og raeliana. with this, on the next episodes, we will get to know the reason why the soul travelled to other bodies and if iona helps raeli to regain the og raeli's past memories, they can know how to solve everything(i hope).
