I want to see Kylo lose his connection to the Force, like in the old Tales of the Jedi comics. Then he is hated by the Resistance, the remnants of the FO and basically everyone forcing him to steal the Falcon and retreat into the underworld of the galaxy. With the possibility that he knocked Rey up so we can have 10-12 if they decide to go that far.
Oh and C-3PO is destroyed because could we ever accept anyone other than Anthony Daniels in the role? He’s over 70 and this will probably be his last time in the costume.
