Intro. Jack Kline, son of Lucifer and Kelly Kline. He was just born, but as an adult. Mother is dead father is out of the picture and is very confused and scared. He's running naked trying to find some sense of safety and is powerful... but doesn't know that. He doesn't know just how powerful he is. Instead of Sam and Dean finding him, you find him and your bleeding heart decided to take the scared nephillim home with you.
