George Lucas was advocating for it? OR are you talking about how he wanted the saga to focus on the family drama MORE (from reports onwhy he disagreed with LucasFilm very early onabout it).
I think regardless of all that, they’re going to meet in the middle – Rey is going to read the TRUE origin of the Jedi, realize that they were both wrong on sides, and convince him that he can be both light and dark – and happy, with her.
I think there were WAY more Force Bond things that happened that we didn’t see – you don’t go from shirtless ‘let the past die’ to scared and quivering (both of them) in a hut talking about your deep dark fears without there being a LOT more to it.
Force bonds grow and become more intertwined – I think that in Ep 9 with the time jump you’ll see that there’s more influence from them,, it happens a lot, etc. and I think they’ll start to be able to do it at will.
