Toni Bevell takes the kidnapped Sam Winchester to a veterinarian to treat the gunshot wound she inflicted in the eleventh season finale "Alpha and Omega", before taking him to another location to question him. Toni explains that the British Men of Letters have kept Britain safe from monsters and now want to expand their influence into the United States. To this end, Toni demands information on all of the hunters in the US from Sam and when he refuses to give her what she wants, she has her assistant Ms. Watt torture him. When Sam doesn't break under physical torture, Toni drugs him in order to torture him mentally with images of his loved ones dying. Sam sees through it and tricks Toni, but is narrowly prevented from escaping. At the same time, his brother Dean finds their long-dead mother, Mary Winchester, who has been resurrected, and convinces Mary of his identity before filling her in on what she missed in the 33 years following her murder. Returning to the Bunker, the two learn of Sam's disappearance and begin tracking him with the help of a returned Castiel. Eventually, Dean is able to call Toni, who refuses to give back Sam and sends Ms. Watt to kill them.

With the birth of Lucifer's son approaching, the Winchesters and Crowley, who survived Lucifer's attempt on his life, search for biblical omens pointing towards the Nephilim's birth. Lucifer kills Rowena so he cannot be sent back to the Cage. At the same time, while taking care of Kelly, Castiel discovers that the baby's power has opened a rift into an alternate post-apocalyptic reality resulting from the Winchesters having never been born. Upon his return, Castiel hides his discovery from Kelly. The Winchesters are eventually able to locate Castiel and Kelly. While Mary tends to Kelly, who has gone into labor, Castiel takes Sam and Dean through the rift where they are greeted by an alternate Bobby Singer. Bobby is able to supply the Winchesters with a machine gun capable of killing angels to use against Lucifer, while Crowley offers a way to seal Lucifer in the alternate reality. As Dean distracts Lucifer, Sam and Crowley perform a spell to seal the rift, a spell Crowley sacrifices his own life to complete. However, Lucifer is able to follow them back through the rift before it can close and kills Castiel. Mary manages to send Lucifer back to the alternate reality, but he drags her there with him, leaving both trapped as the rift closes. While Dean mourns Castiel's death, Sam discovers that Kelly has died in childbirth and finds her son, newborn but having the appearance of a teenager.
