Changes

While [[Sam]], [[Dean]], and [[Castiel]] deal with [[Lucifer]], [[Kelly Kline]] finally gives birth to Jack in an explosion of light that renders [[Mary]] unconscious. When Sam notices the light coming from the home, he goes to check on Kelly, only to find her lying dead in her bed. When he hears a noise, he goes to investigate. He notices footprints scorched into the floor leading to Jack's nursery, where he finds an already adult-looking Jack huddled in the corner, smiling as his eyes glow gold.
