Okay, how about this…does Ben have to factor into her stopping her training at all?
“It was the last night of her training. Leia told me that she…sensed…the end of her Jedi path. She surrendered her saber to me and said that, one day, it would be picked up again by someone who would finish her journey.”
It’s a bit less concrete; but hey, it’s not unusual for Force-users to make random decisions based on vague feelings. “Rey, why are you going after the Dagger?” “A feeling.” “Finn, how do you know about the secondary tower?” “A feeling” “Leia, why’d you give up being a Jedi?” “A feeling.”
We cut out any underbaked prophecy mumbo-jumbo, avoid implying that mothers can’t be Jedi, and dodge the pointlessness of Leia stopping being a Jedi in order to save Ben’s life, when Ben dies anyway. Plus, we make Leia’s journey her own, rather than her just being there for the sake of Ben’s. We would lose the hypothetical “rebirth” double-meaning, but we didn’t really have a plan for implementing that anyway.
And Cap, Hal wanted to include the “Birth of her son” line, so I think discussions about that change are actually relevant to the thread here.
