There was a, uh, period of time when your uncle and I were not on good terms. Well I was not with most of my siblings after the rebellion. I was supposed to stay in Hell and I would have times when the feeling of not wanting to be there would be so overwhelming that I would leave, go to Earth, have fun with the humans. Not as in manipulation but as in hanging out with them. Once it was realized I was missing, our father would send him to make sure I went back or Amenadiel would have to sit on the throne for the time I was gone.
