Jack Kline

Since his father is Lucifer, it is a general assumption that Jack is the embodiment of pure evil. This belief was originally shared even by his mother, who attempted suicide so that her child wouldn't be unleashed upon the world. Jack resurrected her, however, saving himself in the process. Kelly then became convinced that Jack could be good, and that the world needed him. Eventually, after the child helped him defeat Dagon, Castiel also became hopeful that Jack was good, and could make the world a better place. He even claimed to have been shown a vision of a future without pain, fear, or suffering.

Upon delivery, the baby rapidly ages and leaves his dead mother on her bed while he retreats to his nursery. When Sam discovers him, Jack is now an adult and smiles menacingly at the hunter.

Immediately after being born, Jack began searching for Castiel, who he saw as his father, and showed great confusion at the world around him. All that he appeared to know was that his mother was in Heaven and his father was supposed to be waiting for him, but nothing beyond that. While Jack possessed memories from while he was in the womb, he didn't appear to understand what they meant.

Jack Kline stands at 5'10 with short brown hair and blue eyes. He is a very sweet boy but easily startled by the world around him. Being so young, he is easy to become imprinted upon someone or something, viewing it like a motherly role. Even if such person is a man, or by male identification he may still view them as a mother or motherly figure.
