When AJ had pressed the button to go live, there was a little more to it than that. As AJ had stated, he wished to write a book, one that could be passed on through the times, about the life of Quinn and those that followed him.
AJ didn't want the world, the whole universe, to go on not knowing what these people were doing for the humans, the vampires, and all of those that originated from earth. How much sacrifice and pain they had suffered, all for it to be forgotten.
The truth was AJ knew that this would be a dangerous task, ever since he had run into this group at the Chained wedding. He felt like his life was on the line then, and then there were the celestials.
Which was why he knew when he broke the promise to the others, it most likely meant that it too would be the end of his life. Videos uploaded of what had been seen so far were placed on AJ's personal channel.
