I’ve removed Rey’s line. Personally I’m not bothered by this one so much either way (I guess I’ve finally found my breaking point for “stupid, but not movie-breakingly stupid”), but I present this so that others can weigh in:
Removing Rey’s line actually gives a bigger focus to the whispers, perhaps they could be amped up, In fact… maybe the whole concept of Rey hearing her mum’s scream when near the dagger could be axed from the two scenes it appears in, in favor of focusing on her hearing sith whispers instead.
The second time we hear the ‘scream’ is in Kylo’s quarters, where she looks worriedly at the dagger. We could cut before she says “no” and replace the screams of lil’ Rey and momma Rey with more, perhaps louder whispers. This would offer a better setup for the change on the Death Star II and the “only this blade tells”, if we focus on the dagger constantly reaching out and talking to Rey. The idea of the dark side reaching out to Rey, culminating in her following that voice in the DSII would be a really nice way to convey her descent to the dark, and it would be a better/smarter parallel to TFA instead of a lame repeat of hearing someone screaming “no!”.
I’m not a fan of trimming 3PO though, how would he know the dagger is the clue Luke was looking for if he doesn’t know what it says?
