1x11 Scarecrow

After their father sends a message telling them
to investigate the disappearances of young couples in a rural Indiana
town, Sam reveals to Dean that he would rather track down their father,
prompting the two to angrily separate. As Sam meets a fellow hitchhiker
named Meg Masters (Nicki Aycox), Dean starts the investigation and saves
a traveling couple from a living
scarecrow. Dean calls Sam about the creature, and discovers that a
Vanir is being summoned in the form of a scarecrow to protect the town
in exchange for annual sacrifices, with a sacred tree in the town giving
it power. Because the couple intended for the ritual escaped, the
townspeople choose Dean and Emily (Tania Saulnier)a girl who lives in
town with her aunt and uncleto be the new sacrifices. However, Sam
returns and rescues them, and the scarecrow instead takes Emily's aunt
and uncle as its victims. The next morning, Emily and the brothers burn
the sacred tree, and then leave town. Meanwhile, Meg hitches a ride on
the highway, but slits the driver's throat, collecting his blood into a
goblet and using it to communicate with an unknown being whom she calls
father
