Okay, so, I've been thinking for a while about this, and I came up with a theory to explain why all the bad things happened in the books. But it does, unfortunately lead back to Dimitri. I love him, but it does make a whole lot of sense, so here it is: When Dimitri lied to Rose in the first book, it triggered everything.
If he had admitted that he loved Rose when she asked him, she would never have gone to see Victor, so she wouldn't have been bashed around by Natalie.
Also, she wouldn't have been jealous of Tasha, so she wouldn't have told Mason where the Strigoi were, and he never would've gone, and Mason wouldn't have died.
I also think that all the Strigoi were working together. It's common knowledge that the ones in Russia were the ones that organized the attack on St. Vlad's, but I think that they were the same ones that were in charge of the attacks in Frostbite, and that Isaiah had told them about Rose, and so they'd gone to the Academy for revenge. So Dimitri wouldn't have been turned.
So, Rose would never have gone to Russia looking for him, she wouldn't have nearly died fighting him, and they wouldn't have had to break Victor Dashkov out of prison.
And, so, consequently, Rose and Dimitri wouldn't have been fighting, and she would never be with Adrian, and probably not have been accused for killing the queen.
So, had Rose not been jealous, none of this would've happened, and had Dimitri admitted how he felt in the first place, she wouldn't have been jealous.
And, also, if he hadn't said "They have a bond," when he was trying to make Kirova give Rose a second chance, Victor would never have the full knowledge that he had to keep Rose busy when he kidnapped Lissa, and so Rose could've gotten Dimitri while his guardians were still on Campus.
So, there, all explained. All my friends agree with this theory, I hope you do too. I love Dimitri, but it really does make sense.
Review and tell me what you think!
