Moving beyond this exploration of Metropolis' kiss economy, we find Lois and Jimmy working at the Planet the next day, when Superman flies in to give them a box of magic potions that once belonged to Merlin. Somehow, their go-to story isn't "Superman Robs Tomb, Endangers World with Magic".
So finally Superman shows up with a cure for what ails ya. He brings Jimmy to darkened room where "Miss X" kisses him back to his old ginger self.
