lol. I was doing more of my homework and I read this
Tao Te Ching - Lao-tzu
And that is how Sora is.His heart is with everybody because they can see the light that comes from him and reminds them of who they are or used to be while Sora is one giant quilt of people.
I am very determined that Nomura used the Tao teachings as a tool to make KH.
The secret ending is just the ending of KH2. Though a bit weird since all of those scenes with Aqua and AtW are said to take place a year after KH2, but does that mean Sora has been home for a year or that the SRK scene takes place after KH2 and the rest of the "Sora" things are a year later when Sora is on his journey to save everybody connected to his heart?
