Spoiler . . . . . . . . . . . . . . . . . . . . . . . . . . My guess was right! I thought so that Bea was actually the real Raeliana! But, what would burning her real body achieve tho.. She wouldn’t be able to get her body back and still be stuck as Bea?! ┑( ̄Д  ̄)┍
The way I've understood it is that right now both Raeliana and Bea are ill due to both of them being alive. So when Raeliana dies Bea's condition will stabilize. I might be wrong though.
