Oh Rose. I feel so sorry for her. She went through SO much for Dimitri and then, he won't even see her. I have complete confidence they will be together in the end (espeically after his scene in the cafe), but what heart break. And then I feel horrible for Adrian, being pulled into her sadness and most likely getting his heart broken in the end.
My probably wrong guess is that Dimitri will break Rose out of jail before she can be convicted, or maybe after. They will go on a hunt for Lissa's 1/2 sibling. During this journey he will finally allow himself to love her again (also hinted at in the cards- about the journey). I think Victor is connected to(maybe not the actual killer)the queen's murder. I seems a little strange to me that Rose never thinks of him...considering she broke him out of jail, and then lost him. I would think there would maybe have been a little more feeling of responsibility for finding him. My quess is their paths with cross because they are both looking for Lissa's 1/2 sibling. Maybe a spirit user.
