I think trying a version without the radio would be cool to see how it looks, but I wouldn’t want to lose the rest of the dialogue or the laugh. I just thought of an idea for Rey’s vision scene. When the bluray of TROS is out, when Rey’s face is revealed in the ice, have it show Dark Rey’s face instead. This would be a cool tease without giving too much away, because I think it needs something more than just the addition to the shadow and the sith whispers. How the vision plays out says “You’re just Rey.”, but this would tease that there’s something more to the story. You can still keep all of Dark Rey in TROS, but adding this would improve the scene greatly.
