A deep, grating melody echoed through the bunker. Dean looked up from where he'd been getting ready for bed. His gun was alongside him, disassembled while he cleaned it like he did every evening.

It throbbed and pulsed and finally died. Dean frowned and picked up his gun, slotting the parts together with practised ease. He crept to the half-open door. He peeked through the gap and saw Sam coming out of his room.

The brothers looked at each other then cautiously down the corridor.

A massive blue box stood at the end of the hall and blocked their exit. A tall, gangly man was looking down the corridor. He wore a tweed jacket with patches on the sleeves and a bowtie. He spun around, a open-mouthed grin forming on his face and he straightened his bowtie.

He reminded Dean of a teacher he had had in one school. Mr Smith or something.

"Dean!" the man cried and ran down the corridor with the grace of a giraffe. Dean cocked his gun.

"I need to talk to you and your husband." Dean stepped out of his room, standing next to Sammy. He felt a rush, fighting freaky shit with his brother. He understood this, he welcomed it. He did not understand nor welcome the man in the hall.

"Who the hell are you, how did you get in here and this is my brother." Dean said. The man stopped a few feet away and flipped his floppy hair. His eyes had a excited sparkle.

"No." the man grinned. "Your HUSBAND. Y'know the one with the tie... And coat... And the stubble and the little frown squinty thing."

Dean felt himself go red. Cas? The man had described Castiel as his... husband? He felt Sam look at him but he purposely ignored him.

"Dude." Sam said blankly.

The man frowned and put his hands up, turning back to the box.

"No? OH!" his eyes went wide. "Ha, sorry wrong year."

He began sprinting to the box.

"Wait! What about my husband?" Dean yelled. He had to.

The man spun, his coat flapping around his elbows and grinned.

"Summer of '11" the man said happily. "It's gunna be big."

And he jumped into the box, Dean caught a glimpse of machinery and the door swung shut and the box made the yearning song and it vanished.

"Husband?!" cried Sam.

Dean blinked.
"The Hell just happened?"
