Nightcrawler and his girlfriend Daytripper try to save her mom, Margali Szardos, from Belasco. Only Margali has traded bodies with her daughter–so it is in fact Daytripper who is being tortured by Belasco. And even Belasco is unaware of the switch.
The story ends with Margali exiling Belasco and Daytripper feeling obliged to stay in Limbo and preside over it, protecting it. Which means she and Nightcrawler cannot be together.
