After the happy ending finishes, you will see the final scene of Final Fantasy X-2; Tidus and Yuna are at Zanarkand. Tidus will tell Yuna that he was re-created by the Fayth and so he's still a dream, implying that he might disappear again someday. However, if they both cherish each other that won't happen. Yuna hugs him and asks if that's what the Fayth told him, he responds saying that he came up with that idea himself. Yuna then pushes him into the water, after surfacing, he claims that was not cherishing. Yuna tells him that he won't disappear. THE END.
