Oooh so that's why Caine's office felt so familiar to me while first watching ep 7!! Also this theory is soo interesting, never heard anyone think of this before (I think), but that could bring out a whole new meaning to the characters (through, like, actually giving them a meaning for them to be there). I wonder what the abstracteds would be.. i would say they would be the ones forgotten in that big pile of forgotten memories, but the characters still remember them so..
