Roxas: Who are you…again? It’s weird..I feel like I’m forgetting something important.
Xion: [collapsing] You’ll be…better off now. Roxas. [starts to crystallize and return to Sora]
Roxas: [holding her] Am I…the one, who did this to you?
Xion: No, it was my choice. Better to do that than nothing, and let Xemnas have his way…and now, I’m returning. To him. To Sora. Roxas- I need you, to do me a favor. All those hearts I’ve captured- Kingdom Hearts- set them free.
Roxas: Free them? [Xion continues to crystallize]
Xion: It’s too late, for me to undo my mistake. But you can’t let Xemnas have his way. You can’t. Goodbye, Roxas…see you again. I’m glad I got to meet you. Oh, and Axel too. You’re both my best friends. Never forget- that’s the truth.
Roxas: [stumbles, and finally briefly remembers who Xion is] No! Xion! Who else will I have ice cream with? [Xion fully crystallizes and fades out of existence]….Xion. [a tear rolls down his cheek]
