Ok, this is just a chapter to explain some things.
One question that I got was that, if she could go to the Spirit World, why couldn't she go into the Bathhouse, and my only answer to that is that there was a charm set up by Yubaba and it was set up so that Humans (but mostly Sen/Chihiro) couldn't get into the Bathhouse.
Another person asked me why it was rated "M" and the only reason that I went with "M" instead of "T" was because of the suicide.
The way that I could continue this, as a few people have asked is to put Chihiro's spirit into the Spirit World, but as for her living, it is impossible.
I hope that answered some questions.
