It IS a wig. It is like Claire's wig last season in Lost. It is so... scary and ugly, really!

I agree. I wish Ana could stay, really! I liked her. I think that if they were going to use her to tell us about how getting a new wife is, they should have extended it a bit more! But they tell me they had to cut off 2 eps due to the strike last year so I don't know :/
