supernatual lucifer deux

The Lucifer tormenting humanity and the Winchesters wasn't the true Devil. He was simply a terrible creation of the real thing. After many years, the real Lucifer finally gets wind that the abomination he created and locked away is on the lose. Will he succeed in putting a stop to him? And how will the Winchesters react to a not quite evil Devil?
