Hmm, Kai seems to have gotten reincarnated by sinking to the water planet's center, while Stanley spent the entire episode drowning and doing a heaven-or-hell scenario in the planets' weird afterlife. If this is what all the souls do, I wonder how that douchebag guy Fifi got reincarnated on the good planet when he was clearly a betraying bastard.
