I think just “…for my grandchild to come home” and “I never wanted you dead, I wanted you here.”

Both of these are removed to make Palpatine’s machinations a little less convoluted or hard to follow. Irrespective of whatever justifications or explanations from subsequent material, the idea is to make his plan something like this:

He lures in Kylo Ren, enlisting his help to eliminate Rey. He threatens Kylo that if he ties to kill him he’ll possess him. Kylo does not kill Rey and comes to be redeemed into Ben Solo. Rey then comes to Exegol. Palpatine decides to prey upon Rey and tries to get her to willingly become a host for his spirit.

It makes… more sense than the theatrical at any rate. We are given no reason not to believe what Kylo and Rey come to understand, that Palpatine wanted to kill Rey as a child and eliminate her as a threat.

It is unclear to what degree this change reverts the story to an earlier version (sort of like Anakin in my ROTS edit) or creates a new sequence of thought. And honestly, I don’t think it really matters either way.
