It’s up to Hal to decide what works best for the Rey Nobody cut. The stuff I’ve submitted thus far is for the main cut, but I’m sure some of it could be used there, too.
I’ve already shared my audio source files with a few people in the community, so I’m sure they could use the voices to make the Nobody cut better. I’m thinking mostly of the Kylo Ren voice in saying that. I feel like it could be used to great effect in the hangar scene.
