User blog comment:ImperiexSeed/Castiel's shifting of Sam's mental problems made no sense!/@comment-3481504-20120402014311/@comment-4762882-20120402022259

well they started to happen, insanity was definitly happening, while the others did not have time to occur, and cas never saw the possibilty of sam finding a trick(the hand scar), though it only temporarily worked, it did hold it off. I would say, if the hand trick hadnt been found, Episode 17 events might've happened alot sooner.
