Thats a minor characters fate. How do you extrapolate not having a overall plan for the trilogy from that??As JJ Abrams says, reading Rian Johnson's Script and being clueless about the direction, or path of major characters proves the "mystery box" concept. If there was an outline, Abrams would have known before reading Rian's script about their direction from the outline. Outlines hammer home major plot points you know.
What are you not seeing that I am?
