After Zidane had gone to save Kuja, and the roots of the Iifa Tree sealed them in it, we cut to some time later (it really just says 'Some time later...' in the ending), in Alexandria which had been rebuilt. We see the main characters and what's changed, and we see white text on a black background between taking a look at each of the characters. It's Vivi talking about and to Zidane and how he changed their lives. After all that, we get the play "I Want To Be Your Canary", performed by the Tantalus group, though we only get a few scenes from it. A cloaked figure is performing in it and at the last scene, which always gets me since I know what's about to happen, the figure says "Could she have betrayed me? Nay, ne'er would my love speak false. I must have faith! She shall appear if I only believe! As the sun lends me no ear, I pray instead to the twin moons! I beseech thee, wondrous moonlight, grant me my only wish!" and throws it's cloak off, revealing itself as Zidane, and at the same time he says "Bring my beloved Dagger to me!" (The Dagger part is just what you named Garnet at the start of the game, and Dagger is the default name). Then we get a CGI movie where Garnet, or Dagger for those that named her that, starts running off the balcony, being stopped by Steiner and Beatrix who open the door for her. She then starts running through the castle, not a very far distance, and goes outside, running through the people to get to Zidane. She bumpes into one person and loses her pendant, and rather than getting it, she goes back to running towards Zidane. She throws her crown away and jumps into his arms. The two of them hug, and when Garnet pulls away, Zidane gives her a quick smile before she throws her head onto his shoulder and punches his chest lightly three times before he places his hands around her and holds her close to him. Everyone who had watched "I Want To Be Your Canary" cheer for them, and Steiner and Beatrix lift up a sword, presumably Save The Queen, and the camera pans away from the scene, and we get the credits with Melodies of Life playing.
