Note: This story does have a bit of AU, John never met Mary after the Reichanbach fall, and the assassination attempt on Major Shulto was made at an award ceremony. Crazy!Cas never happened. And yes, the title and the chapter titles are from the Chameleon Circuit song 'Nightmares' Also, Everyone is a bit OOC in this first chapter or so, it's hard to get them to meet up without them saying things they wouldn't otherwise.

-Chapter 1-This is What We Have Seen-

~AMERICA~

Dean leaned on his shovel. They were almost done. A few days before, they had given Henry, their Grandfather, a hunter's funeral. A demon, a knight of hell, Abbadon, had killed him. They put a devil's trap in her head, and cut it off. They had buried the body on the other side of America. Dean stood up, sweating and covered in dirt. They had finally buried the bitch's head, and now Dean wanted nothing more than a cold beer and a shower. As they drove away from the burial site, Sam spoke up.

"Do you remember Adam, Dean?"

"You know I do Sam. I still hate myself for not saying yes just to spare him! I could have at least gotten him out of the Pit."

"I know, just family is so important, you know? What, with Bobby dead, we have no one Dean! It's just us and Cas now. So I was thinking, maybe we could bind Death and force him to get Adam out?" he said, sounding like he had rehearsed this

"Yeah. But then what? We would have a crazy Adam, a pissed off Death, and as soon as we let him go, he'll just kill us and Adam, and shove all our asses in the Cage!"

"I know Dean. Just think about it!"

"We are not summoning Death!"

oooOooo

Dean couldn't believe they were summoning Death. Again. Hopefully for the last time. He set out the gift (fries and burger he had gotten from the fast food place down the road), then began setting up the alter. Sam walked in, and simply sat down on the couch, waiting for Dean to finish. As soon as he did, Sam pulled a small sheet of paper out of his pocket and began to read the Latin written there. A bit of wind, and there he was. He gave Sam the most annoyed look Dean had ever seen, worse then even Bitch Face XVII from Sam, then proceeded to eat the burger Dean had brought.

"What do you want, boys?" he said, in his normal lazy manner, still chewing, his too-big eyes fixed pointedly on his sandwich.

"Do you remember-"

"I remember pulling Sam from the Cage, Dean. I told you I won't do it again." Said Death, cutting Dean off.

"Don't you know anything that could help? We can't just leave him down there!" Sam said desperately.

"No. But I know someone who might."

"Who?"

"Sherlock Holmes." And with that, he twisted on his heel and was gone.

~LONDON~

"Boring"

"What about-"

"No."

"Sherlock, you don't even know wha-"

"She killed her husband, she's trying to cover it up by calling us."

"Alright, then what about-"

"Boring." John continued scrolling his email for cases and groaned when he reached the next one. "Another nutter. This one thinks that he's been seeing the same man –the "Doctor" he calls him- all throughout time. At the Titanic, at the Kennedy assassination, at- Oh my god, he thinks he saw him in the Sistine chapel! Sherlock, this man is crazy!" But, Sherlock looked interested. John sighed. "Are you really considering this Sherlock? I mean come on!"

"Look him up." John sighed again before typing 'Clive Jones' into a search window. John was startled to see that he was on the list of the dead, from the time terrorists dressed as shop mannequins and shot a load of people. He told Sherlock, who frowned.

"Let's do some research on this man he saw. Maybe that will lead somewhere not so painfully boring."

oooOooo

Several hours later, Sherlock and John had found a little on this 'Doctor.' He went by many different names, all of them starting with the letter M, but his last name never changed. It was a strange one, so it made him relatively easy to find. John was the one who found him, eventually, near the Forest of Dean, a little cottage on Speech House Lake. He was a doctor, the leading clue he was the one Clive had spoken of. He worked only house-call, but he was very cheap, great for all the small families in the area. He even had a little website with all of his information, and in big letters across the top, was his name. Well, his current name John reminded himself. Mrs. Hudson called for tea, he left, leaving his laptop open to the website of one Markus Emrys.

~SPEACH HOUSE LAKE~

Merlin ran about his house, feeding the cat, Gwen, before running out and around the lake to get to the little boy who had fallen out of a tree, Luke. He was almost there when he realized he hadn't locked his front door. Too late now. His bag hitting his side, he skidded around the corner, and saw Luke lying on the ground, crying and clutching at his ankle. Merlin sighed in relief. He had thought he had hit his head or something more serious. He slowed his pace, walking over to Luke, kneeling beside him.

"What happened?" He asked the nearest adult, Ms. Delacore.

"He was climbing the tree when his arm slipped, and he landed funny on his foot."

"Thank you. Now then, Luke, where does it hurt the most?" the boy pointed to a spot just above his Achilles on the right side. Merlin sighed. It didn't look bad, a few weeks in a brace should do. He pulled out a bandage and began to wrap it around the boy's foot, and making sure his mother was not watching, he quickly used an old spell that would speed the healing process exponentially. He concentrated, pushing it at the boy's ankle. Merlin gasped as something caused him to lean way forward, pushing magic all throughout the wound, healing it completely. Merlin frowned, he hadn't meant to do that, too many questions. Luke sat up, no longer crying, a big smile on his face.

"I'm all better! Like magic! Thank you Dr. Emrys!" he shouted, before running off to rejoin his friends' on the playground.

"Thank you so much, Markus! You are such a blessing on this community!" his mother gushed. Merlin blushed, the strange flair of magic forgotten, and waved goodbye before beginning the walk home.

When he reached his house, the front door was wide open. His first thought was of Gwen, but he banished that thought quickly, how would she have opened it? Merlin entered his cottage slowly, arm outstretched. Before rounding the corner into the kitchen, he stopped and listened. He heard – was that silverware? Had someone broken into his house for food?

"Hello? If that is a burglar, this is your chance to leave. If you just want food, take as much as you need, but I'm coming in for a glass of water."

"Merlin?!"
