Changes

Later, they discover that they tampered with time by pulling John from the past. The consequences include Sam never getting back into the hunting life, Dean being wanted for $100,000 on multiple charges, Mary never being brought back to life by [[Amara]], presumably Jack never being born, and Castiel never meeting the Winchesters. They realize that they need to send John back to 2003 to correct the past. Sam, Dean, and Mary are hesitant, but John accepts that he has to go back. John also tells Dean that he never meant for his sons to have to live the hunter life as it was supposed to end between Yellow Eyes and him. He wanted Dean to have a normal life and have a family of his own, but Dean acknowledges that he already has a family. After sharing their first meal as a family, they gather around for one last tearful goodbye. As John holds Mary's hand, Sam smashes the Baozhu, sending John back to 2003.
