The old man in the castle
O.K so does this symbolize Jack in some way?
is there a connection between his own attempt at suicide earlier on and his ultimate redemption in the breaking into the castle building (his own self absorption/fortress) and then helping the old man who he would have ultimately become if he continued on the way he was? (rich, miserable / self absorbed etc...) you see that he was almost turning back into the same guy again as in the beginning of the film once his agent re-entered the picture.... the same attitude that started the whole mess in the first place.
