So, as I understand it, Kenobi and Yoda's plan had been to rely on Luke or Leia to defeat Vader and the Emperor. From the movies or Expanded Universe materials, is there any indication WHEN Kenobi was planning on training Luke to "save the universe?"
Mostly I'm just trying to figure out for myself what the "Master Plan" was. If I remember Episode III's conclusion right, wasn't Bail Organa supposed to organize a rebellion? Was Kenobi planning on the Force to just scream at him when the time was right? Wouldn't you think that when Bail Organa summoned Kenobi he was also sort of counting on him to bring a young, trained Jedi with him to help save the galaxy?
I realize that Kenobi was limited to Luke's training by his uncle and aunt, but you would think that at some point he would have surreptitiously begun training Luke. And I'm not really looking for answers to the second paragraph's many questions. I'm just trying to explain the reasoning behind the initial question.
