Prologue
His brothers and sisters used to say that he was a good actor - no, the greatest actor in Heaven. It's acting, not lying, mind you. Everybody knew that lying was wrong because Father said so. Therefore, how could the second commander of the Host be lying? No, when he span words and elaborate stories that made the poor seraphs' heads swim, it was not considered lying; he was just an expert of make believe, and the young ones loved it. But after the Fall and the Garden of Eden, he became the Serpent, the snake-tongued, Father of Lies. This change in everyone's choice of words always made him laugh. And plus, he didn't care, or so he told himself. He was a good liar – the world's first ever con artist, and the finest one, too.
So when "angel radio" suddenly turned silent after millennia of chatter and the cage mysteriously opened; when he woke up in his less-than-ideal secondary vessel – on earth out of all places - and realised that his brother Michael was nowhere to be found; when he stood in the middle of the road – honestly he didn't regard casually standing in the middle of a road as being odd – and was nearly run over by a black car; when the furious owners of said car turned out to be the cursed Winchester brothers, his instincts kicked in and he forged a beautiful lie on the spot.
It would be most daring con he had ever pulled: he would tell them that he was his vessel, Nicholas, or whatever that poor sap's name was. And it would work. After all, playing human - how hard could it be?
