Luke: “What are you most afraid of?”
Rey: “Myself.”
Luke: “Because you’re a Palpatine? Leia struggled with her bloodline too.”
Rey: “She didn’t tell me.”
Luke: “Rey, final lesson, some things are stronger than blood…”
What if it isn’t the “dark” that Leia struggled with, but her bloodline and relation to Vader (which is canon I may add)? I think it makes Luke’s final lesson hit a LOT harder too.
