[At that, Tohko nodded, smiling a little. So, this person was friend with Sora. Or a Sora. It was hard to tell if people were from the same universes in a place like this.]

Right..I can understand that. To be honest, I probably would have done the same thing. But you know, even if the Door is still out there and causing problems, the fact that it's still open means that you can close it after you find Sora. The Darkness may cause some problems, but if you managed to beat it back so much that you were able to see the Door, I think you'll be alright.
