First, thank you so much for answering my earlier question. ^^ It came from the idea that aside from R!Ciel and O!Ciel sides of the conflict, there is also third of people close to O!C but on the fence for one reason or another.
In your answer you also mentioned something that started bothering me: does BD!Doll fully knows who she is working for? I mean she might know Blavat or even Undertaker, but is she aware that Lord Sirius is R!Ciel? If so, I think she would, well, not take this too well, given her feelings towards the Phantomhives.
I realize you asked this question before I added a few newer posts on the subject. I think those posts answer your ask as well as they can, with what little information we have so far.
I'm sure we will have to discuss this topic again later. Maybe when Finny and/or Snake confronts her with the fact she's working with/for her sworn enemy's twin, we will learn more from her reaction... and get a better idea of just how much (or what) she was told.
It's very possible she and real Ciel have never actually met face to face....
