As for Harumi's reappearance in Season 12,I think that's her digital backup consiousness - maybe Mr. E...um...scanned the brains of his comrades to be able to bring any of them back if they die,but when Garmadon destroyed him,they (including the nindroid's) were lost in the Ninjanet or whatever they have,and Harumi's double somehow ended up in Prime Empire. That means it's both her and not her.
