Hey guys, thanks for the great explanation it really cleared some things up. I just want to add something that , although it may be obvious for some, i guess thats the point of this video to share ideas. Maybe the markings at Booker's hand are not just the acronyms for his daughter. Maybe A.D. is a way to show just how much the world have ( and will ) changed with Anna/ Elizabeth, just like it did when Christ was born. I don't but it seems like an aweful coinsidence .Anyway great game and great video.
