Yikes. Beatrice is going to murder Raeliana and then pretend to "investigate her death" to get closer to Noah? Maybe frame Vivian while she's at it.
Hopefully Raeliana is smart enough to figure this out quickly. Beatrice has been missing this whole time so she can't assume Beatrice will act in a predictable way. The logical conclusion is that she's also a reincarnator with knowledge of what "should" have happened...
