I’m looney to be thinking this, but would it be easy to make his saber green instead? Could be a subtle way to suggest the events tapped into the existing mythicism surrounding Luke, as people conflate it with his presumably famous green saber.
Just an idea, not even a suggestion! I really love the way this looks. I never knew TROS would give us something this nice.
Faraday did that in his novelization. I opted for the blue saber myself.
I suppose there isn’t a correct answer there, but I went with blue because the green one never shows up in the movie (except the flashback). Rey is wielding the blue one, so it has more meaning imo.
