That Christopher could be Seymour Dorsten? I don't believe in vampires, or anything like that, but after reading book 2 and 3, it seems like he is, as if after the end of book two where she extracts herself from Seymour's life, Christopher IS Seymour, from the change in Point-of-veiw. Remember, at the end of book 2, Seymour was typing the end of his/Sita's story, like he was typing it all along.
What is YOUR opinion on all of this???
