George Lucas was actually treading ground that had been laid 50 years earlier.... by none other than JRR Freaking Tolkien. http://lotr.wikia.com/wiki/Arwen#Aragorn_and_Arwen "Arwen died of a broken heart in 121 of the Fourth Age, at Cerin Amroth in Lórien, one year after the death of Aragorn. She was 2,901 years old." Boom. That just happened. I mean, Tolkien has the upper hand here, considering that how he writes her death is the most beautiful and tragic thing ever (makes zero sense if you don't know the story): " But Arwen went forth from the House, and the light of her eyes was quenched, and it seemed to her people that she had become cold and grey as nightfall in winter that comes without a star. Then she said farewell to Eldarion, and to her daughters, and to all whom she had loved; and she went out from the city of Minas Tirith and passed away to the land of Lórien, and dwelt there alone under the fading trees until winter came. Galadriel had passed away and Celeborn was also gone, and the land was silent. There at last when the mallorn-leaves were falling, but spring had not yet come, she laid herself to rest upon Cerin Amroth; and there is her green grave, until the world is changed, and all the days of her life are utterly forgotten by men that come after, and elanor and niphredil bloom no more east of the Sea." But then again, the intercutting of the death of Padme, birth of the twins, the death of Anakin, and the birth of Vader is also poetic and beautiful in its own way. But the point is, don't let anybody tell you that this idea lacks legitimacy. If one of the greatest authors of the past century used it, it's valid.
