Sam Winchester:
Something... Something bad, is happening in Oasis Plains. We think, it might have something to do with some old bones we found down there. Native American bones.

Joe White Tree:
[nodding] I'll tell you what my grandfather told me. What his grandfather told him. Two hundred years ago, a band of my ancestors lived in that valley. One day, American cavalry came to relocate them. They were resistant, the cavalry impatient. As my grandfather put it, on a night the moon and the sun shared the sky as equals, the cavalry first raided our village. They murdered, raped... The next day, the cavalry came again, and the next and the next. And on the sixth night the cavalry came one last time, and by the time the sun rose, every man, woman and child still in the village was dead. They say on the sixth night as the chief of the village lay dying, he whispered to the heavens, that no white man would ever tarnish this land again. Nature would rise up and protect the valley. And it would bring as many days of misery and death to the white man, as the cavalry had brought upon his people.

Dean Winchester:
Insects. Sounds like nature to me. Six days.

Joe White Tree:
And on the night of the sixth day, none would survive.
