So the 21st doesn’t exist……. Unless umm ya thats it I have done it. The answer is ….. umm what was I saying oh ya so the 21st doesn’t exist.
On to something more important. As to returning to earth I think it is possible. I just don’t know if it is possible to do it as a demon. But if a demon where to be reborn as a human than just maybe they could return. One of my current theories is that Tom has indeed already returned to Earth as the human Tom. And has just recently returned to Astlan. This would explain his rapid progression and development as a demon as it wouldn’t be his first time. Also it would allow for him to be much more then just the sum of his 16 years recently spent on Earth.
