Episodes

12.23 All Along the Watchtower

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 where he notices foot prints leading to Jack's nursery, where he finds an already adult looking Jack huddled in the corner, smiling as his eyes glow gold.
