I know this is probably really late to the party but I’ve been thinking about the Vader Awakens scene a lot lately, and I think you can use parts from Rebels and the OT to make Vader’s final turn more powerful.

E: Anakin? Can you hear me?
V: Where is Padme?
E: In your anger, you killed her

Begin crushing stuff, Sound of using force builds

V: You must use the power of the dark side to save her
E: I’m afraid, my friend, she is lost

Full room crushing
E: Anakin…
V: Anakin Skywalker was broken. That name no longer has any meaning to me.
E: Rise, my friend. I look forward to completing your training.
V: Yes, master.

Breaks free, emperor smile and cackle from ROTJ.

This scene always bothered me, besides the campy scream, because we don’t see Vader make that pivot from sympathetic but misguided villain to cold blood sith lord. All the dialogue above can be pieced together from multiple sources.

Also, has anyone ever taken Palpatine dialog from the OT and used it to replace his over the top performance post-Windu death?
