The door splinters inwards. On the threshold is a man roughly the size of a Jeep. The soldiers shoot, but their weapons have no effect. The giant picks up the radio operator and squeezes his head just out of frame. Blood courses down the front of his uniform. The remaining soldiers open fire. Up until now, the giant's shirt was pristine despite having been shot by untold numbers outside. "Tell your masters this is far from over," says the commandant, switching back to German. He glances at the briefcase, just out of reach, and drops the candle into the bowl. It and the entire room are almost instantly engulfed in flames. The commandant vanishes. The giant scowls, his mission incomplete. Supernatural!
In the present day, the Winchesters are still in Lebanon, Kansas. They drive up to what looks like another abandoned factory. It looks unimpressive to them, too. "When was the last time someone was in this place?" Dean wonders. "I dunno, 65... 75 years ago," Sam says. They find a thoroughly unremarkable door that they then open with the secret key given to them by Grandpa Winchester. This is the place into with old Larry Ganem advised Sam to throw the key and walk away. How would they then re-lock the door with the key thrown inside? For that matter, how was Abaddon -- even with the key -- supposed to get inside if it was "warded against all evil"? Was there only one key that all the Men of Letters had to share? That seems impractical. We're not even five minutes in and I'm already accumulating a stack of questions. This can't be good.
Anyway, the brothers make their way inside. As the slender beams from their flashlights cut through the darkness, little slices of the interior are revealed. There's a hint of Art Deco metalwork, mid-century furnishings and the highest high-tech communication devices the 1950s had to offer. "This was their nerve center," Sam says, awed. "Henry did say they ran dispatch on their own team of hunters," Dean says. So, basically, it's like an older but fancier version of Bobby's and Garth's setups. Dean finds a table with a chessboard in mid-game and coffee cup with a thick stain that seems to indicate its contents evaporated over time. "It's like whoever was manning the hub left quick," he says. He flips the switch on a circuit breaker. Surprisingly, the lights come on. Sam gets his first real look around and makes a face like puppies and kittens and rainbows made of candy hearts just appeared before him.
