Does this mean he'd have to alter Return of the Jedi yet again, just imagine Vader saying to Luke "I am your father!" and then the Emperor adding "and I'm your Grandfather!.... now quickly , Kill your father (i.e. my son) and take your rightful place by your Gran-daddy's side!
Does this also mean that in 20 years time we'll get to see Palpatine as a young boy, romancing a young Schmi, going into politics and turning Evil in the Prequal-Prequal Trilogy , please say it ain't so!!!!!
and maybe we find out that Palpatine built R2-D2?
