I just wanted to pop in and say this scene is coming together really nicely!
With that said, I don’t think Leia cutting off 3PO’s line works. I didn’t know it was coming and once I heard it, it threw me way off and I had to go back and rewatch it. Now, if you had a way to cut to her saying the line, that would be different. Without seeing her say the line, I think it’ll just be confusing as to what is happening.
