THis could just be nitpicking at details, but I went back and watched the scene they showed last night when Jack and Kate find the corpses of who we now know are Jacobs mom and MiB. In White Rabbit, the corpses are not lying next to each other as Jacob laid them down, they are in two different spots. Also, Jack makes a statement about the clothes deteriorating meant they had to have been there for a least 40-50 years. Now, I could be overreacting at some minor details, but I wanted to point these things out. Clearly we know they have been there for a lot longer than 40-50 years, since Jacob was in "power" when Richard got there. And does the bodies being seperate mean anything or is it just an inconsistency?
