You are not Number Thirteen; you are Sora. No matter what happens, you have to remember that. The new heart within you is not welcome, and you're not going to blindly follow Xehanort's orders like the vessel he says you are. You will find a way out of this horrible Organization, and you will reunite with your friends, no matter how long it takes. Even if it means partaking in the web of schemes and agendas that exist among your so-called comrades, you will return to the light. Still, it's hard to be patient when you can feel yourself slipping, slowly ceasing to be you. (AU quest where Xehanort succeeds in making Sora his thirteenth vessel at the end of DDD)
