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.
Stacy, Max, and Eliot meet Jack when he goes shopping at the mini-mart where Stacy works. Eliot is watching the Ghostfacers, and clearly finds them impressive. Stacy and Max invite Jack to hang out with them later at an old farmhouse.
At the farmhouse, Stacy and Max are studying for the SATs, and Eliot is reading a book on monsters, when Jack arrives carrying a load of lore books from the Bunker. As Jack questions the girls about the music they are listening to, Elliot questions Jack about how demons look. Jack reveals they don't have horns and look like smoke, and can possess anyone, and tells them he has killed a demon. Outside Jack shows the others his angel blade. He tries to show them how to throw it into a tree, but misses despite a very large number of repeated attempts. Finally, Jack uses his powers to show off, sending the blade first into the tree and then, after retrieving it, causing it to fly around in the air. As the weapon zips around them, the kids get frightened, but despite repeated pleas, Jack refuses to stop. Stacy panics and steps into the path of the blade and gets stabbed deeply in her abdomen. Max tries to comfort her while Eliot calls 911. Jack intervenes and uses his power to heal Stacy. However, the damage is done -- Max, Stacy, and Eliot tell a confused Jack to leave and stay away.
