Changes

After Jack accidentally kills [[Mary Winchester]], he attempts to resurrect her with the help of [[Rowena]] using a spell from the [[Book of the Damned]]. However, the spell requires Mary's body , which was destroyed when she was killed. Despite Rowena's warnings that he could do more harm than good by trying, Jack casts the spell anyway. Though the attempt causes Mary's body to reappear, it fails to resurrect her. Sam later tells Dean and Castiel that Rowena thinks that Jack's casting of the spell was only capable of bringing brought back a body shell, incapable of holding life. However, it this allows the Winchesters and Castiel to give Mary a [[Hunter's Funeral Pyre]].
