For some reason whenever I see that scene I always think Obi-Wan is going to break out into song about “A Certain Point of View.” I’m glad he doesn’t.
Did you notice in Jedi at the rebel’s briefing when Luke volunteers for the mission, and they hug, and he was like, “we need to talk… but not now.”
I think it wen’t down like this:
Lucas: “we need a way to make it so that Luke and Leia can’t be together””
Other guy working on the film: “maybe we should show that Leia and Solo are truly in love, and so Luke graciously bows out of the love triangle””
Lucas: “I’ll make them brother and sister! I am such a good writer!”
