Just finished the 4th book last night, and like many people, the last few lines about Lucy and Jared stumped me. A lot of people seem to think the Jared in the end is really Nicholas. But this is what confuses me about that theory. We saw Nicholas in the mausoleum. He transforms from Katherine to Angela to Wanda, meaning he was the one who killed them. We also saw him become outraged when he found Jared's blood in Lucy's veins, saw him attack her, kill Matt and engage in battle with Jared. If Nicholas had become Jared, wouldn't there have been two Jareds fighting each other?
