I am so completely satisfied that this collection is over and that I will never pick up any of those books from this sequence once more for as long as I live. I'm the definition of completed. Also, spoilers will likely be abound and aplenty throughout this complete overview, and this goes to a a largely Supernatural gif-crammed extravaganza, as a result of A). That's how angels/demons/and so on. ought to be achieved and B). I can.
