Ok don't beat me up... But I had an controversial idea a few weeks back and it's still there in the back of my mind I wanted some feedback on it....
Return of the Jedi - Emperors throne room
Luke is being electrocuted by the emperors force lightning
Vader grabs the emperor and throws him down to his death.
Luke lays still, motionless (He is Dead)
Vader while clutching on to the railings raises a hand towards luke
Luke comes back to life.
This Idea is based on the darth plaguies mythology "he was powerfull enough to save others from death but not himself" The whole reason Anakin went dark in the first place... Take it in think about it... If you hate it or like it let me know.
Also consider the dialogue between Luke and Vader and how in terms of Luke was Dead and brought back to life by Vader how it would change the emotional context of the lines.
also Vader won't be having a force ghost that's his redemption right there...I am generally not in favour of any changes to the OT to fit with the PT but I am willing to make an exception perhaps on this one if it worked that is.
