<p>1. I would love for it to be Harold Crane. I know he hasn't been in the show a lot, but he is the creepiest character to me, and for that reason the most appropriate to be the AD identity.
</p><p>2. Anyone who is supposed to be dead already, as another member said. I don't like the fake deaths. Alison's was good, but for anyone else it feels repetitive. Also, any of the parents -- I think that would be really sad.
</p><p>3. I would be surprised to find out that it's one of the girls at this point. They've been through so much, why continue the torture? I don't know if the end will shock me, no matter who it is... If I do have that reaction, that would be a nice surprise. But I don't know who would shock me now.
