Dean's POV
The dark and light entwined creating grey then it got lighter and lighter until a face appeared out of the swirling peach and red and black, forming Castiel. He was standing by Dean in the light- slowly, as Dean fell futhur into sleep a background filled the black- it was swirling with colour until Dean's brain decided on the best place. They were high above the Earth, watching it turn.
Dean looked down at his feet, expecting a boat in a cloud or paths people couldn't see that led to Castiel's true home- but instead their was nothing. Which suited Dean because he wanted to just stay. It was perfect, the sound of Castiel' voice, rough and quiet as he spoke of the Earth's birth and why humans get confused. then it all went dark and storm clouds filled the sky, blocking the stars from view Dean turned to Cas who was now yelling, yelling so loud it shook the whole of Dean's body and hurt his head. Then a word and Dean knew why Cas was yelling 'LEVIATHEN!' Cas screamed. Then, it wasn't. Cas's body was limp, his head hung low onto his chest and a distinct drip, drip of goo. Dean's eyes couldn't stop starring 'Cas?' he whispered with a voice he'd forgotten how to use.
There where more words, from Cas. They flooded out in a mocking sly poem then he began to laugh, a smile so wide it looked like it was about to split the angels face. His laugh got louder and his smile got wider Dean knew he was gone. Just like that. Sort of his life story but it was all too real. Like the devil had taken his face and carved something new.
