The scene opens with Terra and Master Xehanort standing somewhere innside the darkness. Xehanort ponders aloud why his control over Terra's body is not yet absolute, seeing that the boy's heart is completely immersed in darkness. Terra states that no matter what happens to him, his heart is still his own. Xehanort quickly denies Terras answer, stating that a part of Terra's heart is already in his grasp and the rest will follow in due time. Terra simply smiles and says confidently he's going to win no matter what. The elderly Keyblade master deduces that Master Eraqus has begun to reside within Terra's heart. Terra states that even if his own heart is consumed and his body becomes darkness itself, regardless of the price, he will achieve this goal. Master Xehanort makes note of Terra's determination and claims there is still time to decide who will have control over the heart. He then states that the seeds have already been sown for his plans.
Image of their backs, preserved in memory.
A familiar face, Xehanort, is seen walking through the corridors of Radiant Garden. Braig approaches him and attempts to start conversation but finds Xehanort not listening. Shocked at his lacking response, Braig immediately deduces that "Master Xehanort" surely has lost all of his memories. Looking into Xehanort's eyes, Braig asks if the man standing before him is actually Terra. Xehanort remains silent, but Braig pats him on the back and states "that it doesn't matter", and Braig's "got his back." As the two walk on, Ienzo and Ansem the Wise appear in the hall, holding hands and eating sea-salt ice cream. Just before he and his young apprentice turn a corner, Ienzo stops, gaining his master's attention. The young apprentice turns his head to see Braig and Xehanort walking away together behind them. Ansem also looks back at the backs of the two men walking away.
Two who were never meant to meet
Ansem the Wise sits in the Dark Margin, wearing his Organization Coat. Aqua appears next to him, asks his name and how he ended up in the Dark Realm. Ansem says it is rare that he has guests and tells Aqua his memory has faded almost completely thus garnering difficulty recalling his past. Aqua sits next to him on the shore and states that she fell into the darkness and has been wandering for a long time, unable to find a way to her original world. Ansem asks why she wants to return, to which Aqua replies she promised she would be there for her friends. Hearing the word "friends," Ansem remembers he had once known a boy who was very similar to her, a boy who is loyal and true to his friends, and travels across the worlds to safeguard the Light.
Ansem tells Aqua that the worlds were almost swallowed by Darkness multiple times and that they were always saved by the same boy who wields a Keyblade. Hearing this, Aqua asks if the boy's name happens to be Terra or Ven. Ansem tells her that it is sadly niether. He then goes on to explain that it has been over a year since he had met the boy. He reflects aloud that through seeking vengeance he did many terrible things to the boy and his friends, causing so many people to suffer. He blames it on his concience and the fact he has the heart of a researcher, and reveals that as the boy slept, he hid his research data within him. Ansem realizes that the boy, whose heart is connected to so many others, could possibly open the door and save those who are suffering because of him, remarking that they are all waiting to be born anew from their Birth By Sleep. Aqua then requests the boy's name. Ansem begins to say it before the scene shifts again.

Where they wait for him...
Sora is sitting on the bent Paopu tree in the Destiny Islands, holding the bottle and letter from King Mickey. Riku walks up to him from behind, asking if he has decided yet. Sora tells his friend that he has. Kairi appears and Sora explains to her that he needs to go help the people who need him, and that he is who he is because of them. So he must leave the islands to help them. Kairi smiles and places her Lucky Charm in his hand and tells him, "See you soon".
