I wonder if she was actually meant to be in Beatrice's body but because of something the original Raeliana was up to, she ended up as Rae and the original ended up as Beatrice. It would then make sense why Beatrice is trying so hard to kill her because she wants to make sure she remains in possession of the Beatrice body. That said, I wonder how the person who killed Rae in her first life fits into everything. I would think it's more than a coincidence she was murdered.
