Blade Runners

Summary

Dean is frustrated when he can’t reach Crowley, who has promised to find The First Blade. When Crowley finally calls Sam and Dean, he tells them he fell off the wagon and has been injecting human blood and needs their help. To make matters worse, he had a demon helping him find blood, but she sold him out and told Abaddon that he and the Winchesters were searching for The First Blade. The brothers need to find the blade before Abaddon does, so they enlist the help of a former member of the Men of Letters.
