Eliot is a teenage boy who resides in Lebanon, Kansas, who has a slight interest in the Winchester brothers' mysterious ways, claiming to have heard a loud bang and shallow breathing coming from the trunk once. His friends do not believe his stories about the Winchesters.
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 is in the 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.
