Yoda "there is another"
This question has been gone over and over and over. Most people agree that when speaking with Obi-Wan, Yoda is referring to Leia. Also, when Yoda is speaking to Luke in ROTJ, it is widely accepted that Yoda is referring to Leia as the other Skywalker. My question refers to Yoda's comment to Obi-Wan regarding another hope. In this scene, Luke wishes to go save Han and Leia. Obi-Wan and Yoda know this, and know that Leia is his sister and the only hope if Luke does not succeed. Yet, they both try to convince Luke to not leave his training and to not go to save his sister and the only other hope. Why would Yoda think that Leia was expendable, then when Luke goes to save her, Yoda says there is another? It doesn't make sense unless in that scene he was referring to another hope, other than Leia. And, it is not Anikin Skywalker. Do we think there is another one of the force besides Luke and Leia in TESB that Yoda knows about, but we don't?
