What if Sid never went nuclear...
It obviously never happened, but what would have happened if Sid finished frying Luke? Would vader have had to pick up the body and throw it down the shaft? Would Sid have allowed Vader to remain a sith, after he just got beaten down by a jedi? If not, would Sid fry Vader? If so, would he try to go get princess leia for a apprentice? If not, who else?
