First off, super impressed how fast you are getting these sample edits out…well done.
For me personally, I feel the force connection between Rey and Kylo at the ends needs to stay as it’s a critical setup for TROS and really just a great scene overall and would hate to see it removed. So, I feel 4A is best the option to incorporate in V3.
However, the fact that Palpatine says “I have been the voices in your head” in TROS I kinda like the idea of 4C as well as we are hearing Palpatine voice in Kylo’s mind. Tough choice! I would happy with either 4A or 4C as they both include the Force connection.
