"In “Blade Runners”, Dean is getting very upset when he still can’t reach Crowley and there’s no word about his progress in finding the First Blade. When Crowley does finally respond to the one million messages Dean has left him, he tells them that he’s “fallen off the wagon” and has been injecting himself with human blood. He begs for their help in detoxing him, but matters are made even more complicated when he reveals he’s been using a demon to find him blood and she sold him out to Abaddon and told her that they’re all searching for the First Blade. Naturally, knowing that it can kill her, Abaddon is determined not to allow the weapon to fall into the Winchesters’ hands, so a race for the First Blade is officially on. In order to help find the Blade, Sam and Dean enlist the help of a former member of the Men of Letters. Meanwhile, Nicole “Snooki” Polizzi appears in a cameo role."
