Some additional random thoughts about some of Leia’s scenes:
I think if we add some extra off-screen dialogue here and there for Leia, it might help make the interactions feel a little more natural and have a better flow. Sometimes it feels like people, specifically Rey, talks to Leia while she just stands there.
One example I thought of would be when Rey is telling her about the Wayfinders. Rey says she has to go, then Leia just says, “No.” I was thinking after Leia says no and it cuts back to Rey, Leia could start saying something else, like a reason why she disagrees, and Rey interrupts her. I think it would help it feel more like a real conversation.
Also, when Rey hands Leia the saber, she says, “I will earn your brother’s saber. One day.” I think this could be changed to “I will earn your father’s saber. One day.” “father” could be taken from her line, “He killed my mother, and my father” from later on in the film. Later, when Leia hands it back, I think it would be great if we gave her a line like, “It’s yours.”
