A random vision of Luke and Vader teaching her to use mindtricks doesn’t make any more sense to me either. I’d say it’d probably distract from the scene instead of improving it.
Don’t worry I was slightly kidding 😃 Among TFA problems are for me these two particular scenes. Not sure they can really be improved. I guess it’s an internal issue that cannot be solved through fanediting. Let’s hope Episode 8 will “fix” it backwards.
