JACK AND KAIA DISRUPT THE WORLD – Jack (Alexander Calvert), desperate to prove to Sam (Jared Padalecki) and Dean (Jensen Ackles) that he is good and that he can control his powers, enlists the help of a dreamcatcher named Kaia (guest star Yadira Guevara-Prip) to help him find Mary Winchester (guest star Samantha Smith) and save her from the alternate universe. However, when plans go awry, the Winchester brothers are the ones who need saving.
