All potentially good ideas, y’all.

JEDIT: That’s a nice line from Leia! I may stick that in and see how it works 😃

I’ve just personally tried to distance myself from using visions as a way to solve problems in an edit since the vision-heavy early days of Starlight, since to me it now feels somewhat artificial, like the hand of the editor is reaching through the screen to tell the viewer what to think and feel rather than allowing the story to unfold naturally. Often, when it feels like we need a vision to explain something, that may mean that this thing should have been established earlier but it wasn’t. An ounce of prevention and all of that.

So it feels like Han’s voice comes out of nowhere in this fight, and it does. Can we foreshadow this earlier in the film?

Possibly. We have already established that Palpatine is ‘every voice’ inside Ben’s head. Later he communes with Vader’s helmet and Palpatine again speaks to him, urging him to kill Rey.

But since Kylo has already been told that Palpatine is every voice in his head, why would he bother trying to commune with the helmet again? It could be that he desperately wants to hear a voice from his family, only for Palpatine to say something like “Vader cannot help you. From the beginning, your only teacher was me.”

Or even, what if he put his hand on the mask and had no visions, but rather heard only Palpatine’s mocking laughter? That way he reforges the mask out of despair of hearing any other voice in his head, all the way until he is about to kill Rey, then realizes that there is another voice in there, one not bound by the Force or visions. It is merely his memory of his father that gets to him, something that Palpatine can never silence. For this, I think it would make sense for Kylo to have no visions of Han prior to this in the film, but for Palpatine to continue saying that there can be no other voices in Kylo’s head but his own.
