Dean's beside himself. "Apocalypse? As in apocalypse apocalypse? As in four horsemen, pestilence, 5 dollar a gallon gas apocalypse?" You mean he doesn't know? It was pretty high when he went south. Is this why they had him sleeping when the boys drove into the Gas & Save? Bobby says that's the one, and explains that the rise of the witnesses is a mile marker. When Sam asks what they should do now, Dean says, "Pfffft. Road Trip. Grand Canyon. Star Trek Experience. Bunny Ranch." Bobby's still thinking with his big head, so he suggests they survive their friends out there, first. He's found a spell that should work (although 'should' doesn't fill Sam with confidence) and thinks he has everything they need in the house. When Dean asks if there's any chance they have everything they need in that room, Bobby says, "You thought our luck was going to start now, all of a sudden?" He really is just like a father to them. The spell has to be cast over an open fire so they'll have to do it over the fireplace in the library. The library? Bobby's got a brazillion wrecks in his back yard, three shirts, two pairs of pants, one fricking baseball cap, and a house with stained glass windows and a library. Isn't that just the way? Dean leans his head into his hand like he's got the world's worst migraine. "This is not as appealing as a ghost-proof panic room, you know?" And yet, still better than Hell, I'd wager, so quit your bitching, Dean, and get moving.
