So let weigh in on this new mystery Strigoi. It might be a far thing but I think that might be Lissa's Brother.
Now let me give my reasons. Lissa is a blonde right? I remember getting them confused because of the covers, but in the Book it said she was a blonde. Now Richelle made it a point to say a couple of times that the guy was a Blonde. Now if you talking about a Strigoi, why would his hair color matter?
The guy also keeps saying he knew Rose and Lissa. I know Rose knew Lissa's brother, so maybe when they were in the car accident, her brother (Andre was his name right?) was not completely dead in the accident but hurt badly and maybe Strigoi was near and bite him, converting him over. In the book they said that Rose saw him when she was seeing ghost so it won't be possible right?
But what if something happened where he is living in two worlds like Rose, but won't that mean he was shadow kissed. But maybe that girl in the new Book, Sidney? Shadow Kissed him and he than got turned into a Strigoi like Dimitri did?
Also Strigoi aren't dead but their not alive either right? So maybe when they are converted their souls are taken out and there technically dead but alive. This could mean that they live in both the dead world and real world, meaning Rose could see them when she see's ghost. Which is why when they are near , she gets a weird feeling. Right?
I know it's a far strecth but I'm just coming up with ideas. Anyone else got any?
