Speaking of leaks, wasn’t there potentially a previous draft of the story where Palpatine did know about the dyad, and everything he was doing was a ruse to get Ben and Rey together so he could slurp their energy out? In the Skywalker Legacy documentary, Chris Terrio lets slip something about Palpatine knowing about the dyad at the beginning of the movie, which obviously is not true of the final edit.
Yes, I seem to remember this as well, and I agree it would have made things more coherent. Unfortunately, JJ and crew seem to hate the idea of deleted scenes. Maybe way in the future when the whole sequel trilogy isn’t as much of a controversial topic they will release them.
