If they don't find something to surpass and predate God, The Death and The Darkness, but they want still overtake for the 13th and 14th seasons that they want to do, scenarists should really try to leaf through the "pandora hearts" manga. It's not visible at the first sight, but thinking about that, I find there are similarities between Supernatural and this manga, and also the naruto manga. In any case, at the level of the primordial entities head motion trio : Death = Glen Baskerville God = Core of Abyss The Darkness : The Darkness of Abyss and there is in spite of these similarities, a being which outclasses the three previous and a nice thinking on the sense of universe. They could find a nice source of inspiration of that.
+KiyokaMakibi I'm so sorry, but no. I ran out of memory after the J2 morning panel and my cell phone washed his face out to a blank white oval. I didn't think it was worth recording. I wanted to, though! He was fun.
