What are your predictions for LAST SACRIFICE? The six most asked questions and an extra + my answers.

1. Who killed Queen Tatiana?
2. Who is Lissa's half sibling?
3. Who will end up with Rose?
4. What will happen with the other guy?
5. Will Rose be found guilty or not?
6. What will happen with the throne and the age decree and all that?
+ My extra question.
1. Victor Dashkov, cause he couldn't have just disappeared like that, he's got to reappear sometime; we know how badly he wants the throne; and we know Rose would be his first choice to frame. Ambrose is an impossibility and Daniella Ivashkov is highly unlikely(as is the Queen committing suicide)
2. A moroi 100% sure, younger than Lissa 70%, and a girl 55%; moroi cause we all heard about the moroi showgirls in Las Vegas and Eric Dragomir's mysterious bank deposit there, younger cause the eldest, Lissa has to take the political part and vote, and a girl just because she already had a brother(more wishful thinking than guessing)
3. Personally, I can't pick for myself, but I think Rose would ultimately choose Dimitri (although she would hesitate cause she really cares about Adrian)
4. Either Adrian will accept the fact that he got rejected and still remain friends with Rose, (cause it's impossible to imagine them not talking to each other) or he will die before Rose has to make the decision.
5. More likely she will be found guilty and has to run away; it would be too easy if she wasn't.
6. One way or another, Lissa is going to be Queen(never mind the timeline there), the age decree will be voted off but the morois' stupid cowardice will probably remain, the idea of moroi fighting strigoi with magic will be more supported, but not approved of.
+ My question: do you think spirit may have turned Dimitri moroi? Think of it this way: he and Rose should have a future together(=kids) and the moroi need someone to show them that fighting with magic is a good thing, right?
So what do you think, and what are your answers to the questions?
