I’m taking a very JJ Abrams approach with it, which is basically do it quickly and don’t ask too many questions. Basically, the path of least resistance - cut out all discussion of Rey’s parents trying to protect her and any flashback that shows them loving her and standing up to Ochi. All we see and know is that Palpatine was looking for Rey, and when Ochi couldn’t find her he killed her parents. Does it make sense? Maybe not. But I don’t think it makes any less sense than what we get in the theatrical.
