It’s kind of weird how we never find out how Kylo Ren finds out about the concept of a Dyad in the Force. When he first says it to Rey, I thought it might just be a figure of speech, but then when Palpatine says it again in the climax, it definitely seems like the Dyad is something special, like the Chosen One.

It’s really too bad we didn’t get the Oracle scene, because it would’ve been a great way for Kylo to learn about it independently of Palpatine’s influence, since Palpatine didn’t know about it until they both were in front of him. Since it was called the Oracle, it would’ve been cool if it had been the source of not only the Dyad concept, but the Chosen One prophecy.

The only other way I can think of seeding the idea earlier in the film is if Kylo hears himself say “a Dyad in the Force” during one of his visions. It can’t be when he touches Vader’s helmet, though, since it has a connection with Palpatine (who doesn’t know about the dyad). Maybe he could have a vision when he touches the Wayfinder that could hint at the Dyad.

Maybe you could edit the film to make it seem like Palpatine knows, and told Kylo about it at the beginning of the film. So you would cut Kylo’s line, “What Palpatine doesn’t know…” but keep “We’re a Dyad in the Force, Rey.” But I haven’t seen an edit yet where Palpatine doesn’t seem surprised by the power of their bond during the climax, so I don’t know if that would work.
