[SPOILER] Leia's dialogue...
Or the lack of is really palpable. I know they use unused scenes from previous movies. I don't think they add many extra dialogues besides the unused one, the only one that I can spot is probably when she hugs Rey and is facing away from the camera (unused scene from before Rey goes and looking for Luke probably)
So it's really weird seeing how all the characters are speaking, and Leia only responds with one sentence each time.
And the scene where Rey gave Leia Luke's lightsaber because she thinks she's not ready is probably to accommodate the scene where Leia is giving her the lightsaber back. Again probably a deleted scene from the end of episode 7.
