   Summary

   TSITP x The Ultimatum

   Belly and Conrad sign up to go on The Ultimatum, a reality show filmed in a tropical paradise for people who can't decide if they should get married or walk away from their partners for good.

   And on the first day of filming they discover Jeremiah--who ghosted Belly on their wedding day with no explanation--is also part of the cast, changing everything.

   *Takes place five years after Belly chose Conrad with deviations from canon. Team Jellyfish.*
