"What the hell?" said House, grabbing the table for support. The floor was shaking. A mug fell off the sideboard and shattered.

"Earthquake! Everybody under the table!" Thirteen announced. House groaned. He really did not like crawling.

"Not an earthquake," Sam corrected, from the doorway.

"Of course it's an earthquake, you idiot. The earth is quaking." House glared at the tall young man who was blocking the exit. He looked surprisingly healthy for someone who had been at death's door, not an hour and a half ago.

"Not an earthquake. Where's my gun? I'd say we have about 27 minutes until the world turns to fire and this guy's lungs get ripped out."

The three doctors stared at him incredulously. He must have been having these delusions for years to say that so matter-of-factly.

"I'm serious! We have to move! In about 15 minutes this whole room will be on fire and the exit will be blocked, and the demons will come and kill us all painfully! Look, I can prove it. It was in my vision. Another doctor, Dr Wilson, or Watson or something, is going to come into this office, and the floor is going to shake, and he'll fall over, and that book-" Sam pointed to a thick volume on the table, "-will land on his head."

"Shut up and get under the table."

"Thirty seconds," said Sam, but he got under the table just in case. "Ten... nine... eight...sev-"

"House? Are you in here?" Wilson opened the door and stepped into the room. The floor gave a great shudder, and he stumbled forward, sprawling on the floor by the table. The room quaked once more, and House watched in amazement as the heavy volume slid from the table.

"Watch out!" cried Chase.

"Guh!" said Wilson, as the book thudded into his head.

"Believe me now?" asked Sam, crawling out from under the table to check Wilson's pulse.

"Your gun's in my desk," said House.

"We have to get out of here," Dean told the shrink. She looked scared. Crap. Just his luck to be stuck with a panicked female during the demons' assault on the world. She looked like a crier, too. "Come on," he said, pulling her out from under the desk.

"But it's an earthquake," she said, "we have to stay here, the desk will protect us from falling debris."

"What's your name?" Dean asked, as the floor shuddered again, and he almost lost his footing.

"Sarah," she whispered, clutching his arm.

"Well, Sarah," he said calmly, as if talking to a small child, "We have to leave. This is not an earthquake. The demons are opening a gate to hell, and if we are here when hell escapes, we are going to die, and the world is going to end. Do you understand me?"

"Just calm down, Dean. I know this feels like the end of the world, but it's just an earthquake. It's your delusions that are telling you otherwise – argh!"
