Part 2 – dream a little dream
Bobby hunts this boy he once loved like a son, and he does it alone. He sees Dean's handiwork when he's awake, bodies strewn across the landscape, burned and discarded like trash.
Dean shows up in Bobby's dreams, just as snarky and cheerful as he ever was. He talks a lot about Samuel Colt's special gun and Bobby listens.
"See you in New Orleans in two weeks, dude." Dean disappears with a wink and a smirk.
He's sitting down by the levee when Bobby walks up. Dean looks up and smiles.
Bobby raises the special Colt and fires.
