@ precious hair-san and Rufus Barma.
The explanation for the blood is that Barma WANTS to be blamed for the murder. Why? ummmm....I'm still working on that part. But If he used the illusion to kill Lady Reinsworth of course he is going to be covered in blood. I mean he must have put loads of effort into that ^^;
And being a fangirl of Vincent Nightray, having Barma turn to the dark side is seen as a win for me *shot*
But I doubt he really killed her unless she magically was working for the baskervilles. Rufus isnt that kind of guy.
Though I do still hold my chocolate chip cookie theory.... *double shot*
