When it comes to the original trio not being together for one moment? It sucks but sometimes that happens in storytelling. JJ was honestly right to tell Mark that. It’s not Luke’s story anymore, this is not about the original characters
What does having the original trio together have to do with it not being Luke’s story?
Well truthfully, it has nothing to do with that aspect but what JJ was conveying to Mark Hamill is that for the sequel trilogy, the focus isn’t really on the main trio anymore. Mark Hamill has consistently been on this thing of lamenting that he never got a chance to be with Harrison, Carrie and Billy Dee again which is fine but what one comes to understand is that a story is not going to always cater to your personal desires but rather what a storyteller is looking to do.
