2x02 Everybody Loves a Clown

After cremating their father's body, Sam and Dean refuse to discuss his death. Instead, they head back to work, and track an old message on John's phone to Harvelle's Roadhouse, a bar frequented by hunters. There they meet Ellen Harvelle (Samantha Ferris), an old friend of John's, and her daughter Jo (Alona Tal). As the group's resident genius, Ash (Chad Lindberg), attempts to analyze John's research on Azazel with his computer, the brothers investigate the murders of visitors to a traveling carnival, currently near Mishicot, Wisconsin. They discover that a Rakshasa—a demon of Hindu mythology—has been taking the form of a clown and tricking children into inviting it into their homes so that it can eat their parents. When not feeding, it takes the form of a blind knife thrower at the carnival. The brothers kill it with a brass pipe. Dean later takes out his anger at his father's death on the Impala, one of his most prized possessions.
