A/N: Hi so sorry about the time taken! Kinda got writers block. Okay so I meant to make this a kind of Johnlocky sweet chapter but it ran away with me. Sorry about that. Please R&R! Enjoy!

Sherlock, it's okay, we promise

John finally caught up with Sherlock, almost running into him as he hid inside a dark warehouse.

"Sherlock?"

"They can't exist, John. Angels don't exist; people can't time travel and there are no such things as Leviathans. The laws of physics don't allow it. They can't exist, John!" John looked Sherlock straight in the eye and spoke as if talking to a frightened child,

"It's going to be okay, Sherlock. We'll work it out. Remember Baskerville? Remember the hound? We worked that out, didn't we? And so we will work this out too. I promise you." Sherlock looked up sceptically and held John's gaze for a good few seconds before looking away.

"Oh, how adorable, the food is having a moment." John spun around and stood as a man walked out of the darkness. He grinned psychopathically and opened his mouth, showing a huge maw. John screamed.

"Now where have they gone?" cursed Gabriel, looking around at the three or four different warehouses John could have run into. Before anyone could make a suggestion, there was a scream. Without a second thought, the seven of them ran straight into the nearest warehouse. John ducked as the Leviathan lunged at him.

"Hey! Big mouth! Eat this!" yelled Dean, spraying the Leviathan straight in the face with floor cleaner. It screamed and Sam took advantage of the momentary low guard and lopped its head off. They were all splatted with the black goo that Leviathans bled.

"Eurgh! That is disgusting," grumbled Sherlock. Gabriel fixed him with a dark glare and clicked his fingers. Sherlock vanished.

"Gabriel…" Cas said exasperatedly. John looked terrified. Sam rolled his eyes at his boyfriend.

"Gabe. Bring him back or at least send John with him." Gabriel shrugged acceptingly and clicked his fingers again. John promptly disappeared.

"Why do I even try?" asked Sam.

"Hey, you love me really!" Gabriel snuck up and kissed Sam before he could react. Sam relaxed into the kiss until his brother cleared his throat very pointedly. Sam and Gabriel broke apart and Jack laughed slightly.

"Where'd you send them?" asked Cas.

"Nowhere important. They'll be fine." Martha frowned.

"How did you do that?"

"He's a Trickster," said Dean. "They are almost demigods, and they have the power to create places and things. And because he's also an Archangel, his powers are heightened. He can create whole realities and send people there. I assume where you've sent them two is relatively safe?"

"Very safe!" exclaimed Gabriel. "It's just a room. I promise!" He raised his hands in surrender.

"Come here, you," Sam said and they began kissing again but the Doctor yelled,

"Get a room!" and everyone started laughing.

"Okay then!" Gabriel said in mock-offence. There was a flutter of feathers and he and Sam vanished.

"Typical," said Cas. Dean, Cas, the Doctor, Jack and Martha left the warehouse to meet an army of about 70 demons.

"Ah."

Gabriel! Get your and Sammy's lazy asses here right now! Gabriel and Sam reappeared, looking slightly shocked at the amount of demons that stood in front of them.

"Guns at the ready!" Dean yelled, hefting his Purgatorian blade. Martha and Jack loaded their guns; the Doctor gripped the holy wood; Gabriel and Cas summoned their angel blades and Sam drew Ruby's knife from his belt. And then they charged.

John was very surprised at suddenly appearing beside Sherlock in a window-less, door-less room. It was clean and white with golden panelling and there were two comfy-looking chairs in centre of the room. Sherlock was slumped exhaustedly in one so John walked over to join him.

"We can't get out. How did we even get here?" asked Sherlock in his bored voice although John could detect a slight hint of fear.

"Gabriel, I presume. The tallest one, Sam, said that he had to bring you back or at least send me with. And so Gabriel clicked his fingers and bam! I'm here."

"This can't be happening. Are we going mad? Am I going mad?! John, I don't want to go crazy!" Sherlock looked more vulnerable than John had ever seen him and he had the sudden urge to hug him. But he couldn't. Because this was Sherlock Holmes and he disapproved of physical contact. John sat opposite Sherlock and he leaned forward.

"Sherlock. Listen to me. You are not going mad. I know this because I am a doctor and I know when someone goes mad. Believe me, I've seen it. This is real and I know that will be hard to wrap your brain around but we can't deny it. This is all real." Sherlock shook his head adamantly.

"No. It can be."

"Give me another explanation."

"Drugs, obviously."

"No."

"What do you mean no? It's the only explanation."

"No. If we had been drugged, I would be out cold before it could even affect you. It would have had to have been a terribly powerful drug to create something this realistic for both of us because you're far too tolerant to drugs for that," John rationalised easily. After thinking for a moment, Sherlock realised John was right. Drugs were not the answer but yet how could this be real?

Castiel waded through the army of demons, slashing and smiting. He saw nothing but blood and white light as he advanced and all he could hear were screams and yells but then one voice stuck out.

"CAAASS! LOOK OUT!" He spun at Dean's scream and gasped slightly as a knife met his stomach. It wouldn't have worried him but it seemed that one or two demons had angel blades and this one had caught him. Everything slowed down and all the colours seemed too bright as Cas fell roughly to his knees. The sound of fighting had faded to mulled constant noise by the time Cas looked down at his stomach. There was a silver-handled blade sticking out and glowing white Grace spilling out. Vaguely, he wondered why none of the demons had finished him off, until he realised it was silent. Hands on his face, warm comforting hands and Cas looked up. Dean's hands.

"Cas! Stay with me, buddy. I've got you. I promise, I'll never let you go. Cas? Cas! Castiel!" Dean screeched and the angel in his arms fell still. Gabriel limped over (he'd tussled with the other demon carrying and angel blade and won but been rather badly injured in the process) and sighed sorrowfully at his fallen brother. Sam helped an injured Martha over whilst Captain Jack picked up the unconscious Doctor. The stab wounds on his hands and chest healing, Jack lay down the prone Doctor (hit rather hard over the head) and pulled Martha towards him as Sam dropped to his knees next to his brother who was sobbing quietly.

"Tell me he's not dead, Gabriel. Tell me that he'll recover…"

"Dean…" Gabriel said and Sam was slightly shocked to hear the cocky angel's voice crack. "He may not be dead yet but there's no healing. He's too far gone. Castiel…" Sam stood and pulled his angel into a tight hug, tears filling his grey eyes. The last word Gabriel had uttered broke Sam because he had known him for so long and he had never once seen the angel cry. Yet, here, now, scalding tears were dripped from his whiskey-coloured eyes.

Jack sighed softly and pulled Martha closer to him. It seemed wrong, watching this. Dean sobbing, rocking back and forth, hugging Castiel's body; Sam was clutching a weeping Gabriel, tears falling from his own pain-filled eyes. This was a broken family. Jack had seen enough to know the look of people who relied entirely upon each other and even though they were different ages, heights, looks and even species, they were the closest family that Jack had ever seen. And now they had lost one of their own. And that kind of hurt would never heal.
