I am sitting here watching Revenge of the Sith and have a question about something that Palpatine said to Anakin right after killing Mace Windu. Anakin asked Palpatine to help him to save Padme when agreeing to become his apprentice. Palpatine made the statement that only one has overcome death but together they would try to ensure that Padme didn't die. Who was the one that had overcome death previously? I am just not as knowledgible as alot of you guys about this stuff and figured one of you would know.
