Leia did play a part in Vader's redemption. She was a catalyst that started it all when Vader threaten to turn her to the Dark Side and Luke, getting pissed off over this remark, lashed out all his fury at Vader and defeated him. She also drove him to become Anakin Skywalker again when he witness his own son getting fried by the Emperor and he thought in his head, "If I don't do something now to save my son, he will die and the Emperor will soon find my daughter and kill her too. I must not let that happen" so in an instant, Vader redeemed himself when he became Anakin again and saved Luke by throwing the Emperor down the reactor. Ahhh, PMT99, the "other argument". This is an excellent, excellent point. And as far as I can see, the only logical way in which Leia can be considered "the other". The oblique reference. It's not that she's the other in a direct sense, but that the thought of her ultimately saves both her brother and her father. Still, there are problems with this argument. First, it turns "another" into "two others". Clearly, it's Anakin who does the actual work of saving the galaxy. It's Anakin who finally becomes a Jedi Knight, fulfills his destiny, and restores balance to the Force. Leia may be the passive redeemer of the Skywalker family, but it's Anakin who is the active savior of the galaxy here. This isn't too much of a problem, though, because another is not defined as "only one other". Second, I believe that the goal of Yoda wasn't just the defeat of the Emperor but the rebirth of the Jedi. Though SW6 hints at the training of Leia, and the EU surely expands upon that possibility, I'm personally not left at the end of SW6 believing that she's going to be a Jedi Knight. I find it much more likely that she'll receive some Force training, but essentially stay where her talents so obviously lie: the political arena. It's speculation, of course, but, then, so is the EU, IMHO. Third, I still don't get how she could've been "the other" if Yoda thought her expendable enough to let her die on Bespin. You've made the point, before, that Yoda couldn't see her future and therefore didn't know she was going to die. But if he didn't know she was going to die, he obviously didn't know she wasn't, either. So it was an eventuality he considered, and deemed less important than Luke's training. It's extremely unusual strategy to allow your backup to die. It seems especially odd to me that she could be "the other", even in this passive sense we're discussing, if Yoda's uncertain whether Leia will survive to be that potent catalyst later on. Having said all that, though, it's still a strong argument that Leia's "otherness" wasn't about direct confrontation or her Force aptitude. Rather, it was about her role as touchstone, and how that would help Luke overcome the Emperor and eventually become the progenitor of a new Jedi class. I must say, though, that while I can see this argument, it's too indirect for my tastes. Nor is it literarily satisfying, since the films ultimately have to do with Anakin, and Obi-Wan's role in training Anakin.
