So if the necklace payoff is reinserted in Episodes 1 & 3, a close up shot could be created by one of the awesome editors here of the necklace on the ground of the landing platform on Mustafar before Obi-Wan and Padme leave, implying Padme left it there while Obi-Wan and Anakin are fighting. You could then cut out Padme saying there is still good in him if you haven’t already. Then, in terms of watching as a saga, it could imply that only Luke believes his father can be redeemed and Padme gave up on him.
