Later that night, Julia, who continues to tell her story in the present to Sam, was curious about noises and went to check them out. She is taken hostage by Mother Superior along with several other people. Henry and Josie arrive and start to perform an exorcism but it does not work on AbbadonAbaddon, who knocks out Henry. Abbadon Abaddon concludes that Josie and Henry are Men of Letters, and she decides to possess Henry. However, Josie asks Abbadon Abaddon to possess her instead. Julia watches as AbbadonAbaddon's smoke flows into Josie. Abbadon Abaddon vows to destroy the Men of Letters and asks Sister Agnes to continue with their project. Henry awakens and he isn't aware that Abbadon Abaddon has possessed Josie.

Meanwhile, at the bar, Dean is playing pool and talking with Crowley who thinks Dean is stalling on finding Abaddon. Crowley accuses Dean of being scared of [[the First Blade]], and he irritates Dean by comparing Dean to [[Cain]]. Dean claims to be nothing like Cain, but Crowley continues to force the issue. Crowley excuses himself to go to the restroom, and Dean again remembers holding the First Blade. He then notices a young man, who appears to be a [[hunter]], follow Crowley to the men's room. Dean follows him the hunter named Jake and stops him.

Then, Dean berates Crowley for his blood addiction. Crowley, in turn, says Dean is a junkie too –- — he is 's addicted to the power brought on by the Mark and the First Blade. Dean counters that he just wants to kill Abaddon, no matter what the consequences. Dean leaves, and the young “hunter” Jake appearssporting a pair of black eyes. Crowley has set up the confrontation to confirm that Dean would save him , and now that he's sure of Dean's camaraderie, he knows that “he is 's ready.”

During this time, Sam investigates at the convent. Just as he discovers a number of jars with glowing lights in them, a demon arrives, and Sam kills him with the knife. Another demon, Sister Agnes, knocks Sam down, and then tells him that the glowing lights are [[souls]]. She laments that it has become more difficult to steal souls, but it is necessary to make an army for Abaddon. She tells Sam that there are other demons doing the same thing. Sam starts chanting the exorcism but Sister Agnes begins choking him so he can no longer speak. Sam pulls out his phone that has a recording of the exorcism and he then tosses the phone across the room. Sister Agnes lets go of Sam and dives for the phone in order to stop the exorcism. Sam kills her with the knife. He then opens the jars and watches as the souls go free to return to their bodies.

[[Sam]] travels to Milton, Illinois to investigate the case. [[Dean]] is seen at a bar called The Milton drinking and playing pool. Fans suggested that this may indicate that Dean followed Sam to Milton, or that it is simply a visual metaphor for their connection, despite their separation. The name Milton may be a reference to poet John Milton who wrote the epic poem ''[http://en.wikipedia.org/wiki/Paradise_Lost Paradise Lost]''. The poem tells the story of Satan and the angelic wars, as well as Adam and Eve and their relationship and fall expulsion from [[Heaven]]. It could also be a reference to the drug [https://en.wikipedia.org/wiki/Meprobamate Meprobamate], marketed as "Miltown," and the drug referenced in the song "Mother's Little Helper."
