In 1958, Larry Ganem is one of the elders of the Men of Letters chapterhouse in Normal, Illinois. Abaddon massacres the Illinois chapter while trying to obtain the key to the Men of Letters Bunker, which he gives to Henry Winchester for protection.
Henry uses magic to create a portal which takes him to the year 2013, but he is unknowingly followed by Abaddon. Henry finds Sam and Dean and they manage to locate Larry Ganem, still alive, in Lebanon, Kansas. He gives them the coordinates to the Bunker but he pleads with Sam to lock the key inside the Bunker to prevent Abaddon gaining access to the knowledge kept there. When Abbadon locates Larry, she possesses his wife and kills him, while she takes Sam hostage. In an exchange with Dean for the key, Henry is killed, but not before he is able to shoot her in the head with a devil's trap bullet which locks Abaddon into her meatsuit, allowing Dean to decapitate her and ensuring she is trapped in the body.
In the aftermath, the Winchesters take the key and decide to find the Bunker.
Sam and Dean are able to locate the Bunker built beneath the foundation of an abandoned power plant. After exploring the underground lair, the Winchesters decide to move into the Bunker and use its contents to aid in their battle against evil, effectively turning it into their home.
Sam and Dean hunt down a banshee that has been causing the residents of a retirement home called Oak Park to kill themselves. The home is 15 minutes from the Bunker.
Standing outside the Lebanon Vista movie theater with his friends, Eliot begins talking about Sam and Dean and how mysterious they are around the town, and how he's seen and heard weird things around them. Stacy tells him to stop creeping Max out just as Sam and Dean pull up and park the Impala in front of the theater. Eliot continues speculating on where Sam and Dean come from, but continues to get blown off by his friends.
When Max decides to steal the Impala, Sam and Dean quickly confront Eliot, who only claims to know Max's first name. After his confrontation with Sam and Dean, Eliot races to the party to warn Max, but is similarly blown off by Stacy until Sam and Dean show up claiming to be FBI and kick everyone out of the house. Still curious about the brothers, Eliot throws caution to the wind and runs back inside chased by Stacy and Max who all witness the ghost of John Wayne Gacy burn away.
Sam and Dean sit the three down, and rather than come up with an explanation, they tell the truth about the supernatural. Eliot excitedly exclaims he "knew it" and they are told to keep what they know as their secret.
In the alternate timeline, Eliot and his friends are having dinner in an Italian restaurant when Zachariah and Castiel arrive demanding answers for who messed with time. Zachariah and Castiel threaten to kill everyone within before Sam and Dean intervene, sending everyone away before killing Zachariah and banishing Castiel.
Later that night, after the original timeline is restored, Eliot is seen walking the streets alongside Max and Stacy, excitedly talking about the Winchesters and what they had revealed to them about the world.
