Wow I’m really loving this new clone angle. The only thing I’d be sad about going is the Dyad wording. I think it may be worth trying to include that word in there somewhere, especially because I’m sure in future material the Dyad will come back up, so it’ll be more cannon friendly and “future proof”.
Well, Ben Solo is dead, so I somewhat doubt it would ever come up again unless they do something crazy like resurrecting him in the next movie. But, yeah, it is a cool concept nonetheless. Maybe there is a way to weave it into there. Or we could just have Palpatine define their connection at the end there and not have Kylo define it. Because it’s never actually explained why or how he knows they’re a dyad. Obviously Palpatine didn’t tell him, and he’s the guy that would be well-versed on the intricacies of the Force. Maybe it would be best if it’s a surprise to everyone in that moment with Palps at the end. That way we’re also not revealing too many things about Rey in the hangar which would distract from the main point of it all.
By future material im mostly thinking for some sort of series that will likely be made in the future set in the gap between episode 8 and 9, likely explaining how Kylo even knows about the Dyad aswell. I just imagine its fairly likely that it will come up again at some point, so if its able to be maintained I think it would be a good call personally. I would be down for just Palpatine knowing about it too though, though thay may seem a bit out of left field if Kylo didn’t mention it before.
