After Serge returned home, FATE sent Lynx to kill Serge, hoping that it would release the Arbiter lock. Ten years after Serge drowned, the thief Kid—presumably on Belthasar's orders—went back in time to save Serge and split the dimensions. FATE, locked out of the Frozen Flame again, knew that Serge would one day cross to "Another" world and prepared to apprehend him. Lynx switched bodies with Serge to dupe the biological check of Chronopolis on the Frozen Flame. Belthasar then reveals that these events were part of a plan he had orchestrated named Project Kid. Serge continues to the top of Terra Tower and defeats the Dragon God. Continuing to the beach where the split in dimensions had occurred, Serge finds apparitions of Crono, Marle, and Lucca once more. They reveal that Belthasar's plan was to empower Serge to free Schala from melding with Lavos, lest they evolve into the "Time Devourer", a creature capable of destroying spacetime. Lucca explains that Kid is Schala's clone, sent to the modern age to take part in Project Kid. Serge uses a Time Egg—given to him by Belthasar—to enter the Darkness Beyond Time and vanquish the Time Devourer, separating Schala from Lavos and restoring the dimensions to one. Thankful, Schala muses on evolution and the struggle of life and returns Serge to his home, noting that he will forget the entire adventure. She then seemingly records the experience in her diary, noting she will always be searching for Serge in this life and beyond, signing the entry as Schala "Kid" Zeal, implying that she and Kid have merged and became whole again. A wedding photo of Kid and an obscured male sits on the diary's desk. Scenes then depict a real-life Kid searching for someone in a modern city, intending to make players entertain the possibility that their own Kid is searching for them. The ambiguous ending leaves the events of the characters' lives following the game up to interpretation.
