A/N: FYI I've never been to Cambridge and I don't know much about it. Everything about Cambridge has been google searched so it could be completely and utterly wrong. But the setting doesn't really matter that much. Setting aside I hope you enjoy the chapter.

Chapter 15

They'd found a case in Cambridge. Recently many people that had been hiking through the local forest had been found dead near a local cemetery. The bodies had been covered in cuts and bruises and what looked like claw marks... Well, not exactly claw marks. Kinda like the kind of marks you'd get from someone with really long fingernails. the bodies also had been found with bite marks on them.

Even though it could possibly be nothing, they'd gone to investigate. It could simply be an animal attack or a run of the mill killer. But they Deanna had been itching for a hunt since she'd gotten back from hell. They had all been cautious to let her out on a hunt but after she'd stolen John's gun and started shooting the wall (similar to what Sherlock did when he was bored) they'd reluctantly let her out on a case.

They'd tried to find an easy one to begin with. Deanna had insisted on finding one for them to take stating that it'd make her feel more normal. Well as normal as you can be when your job is to hunt down monsters.

Here we go again. John thought to himself.

When they arrived at the morgue to examine the bodies the police officer recognized them. Well Sherlock and John to be exact.

"Sherlock Holmes and John Watson? What are you doing here?"

"We're here on a case officer, now if you'd kindly let us examine the bodies which have been found in the graveyard."

"Sorry Mr Holmes I can't do that for you?"

"And why can't you?"

"You're out of your jurisdiction here."

Sherlock looked at the officer clearly trying to think of an excuse when Deanna stepped up with her fake FBI badge in hand.

"Hello officer, I'm Deanna Smith. FBI. These men are with me." Deanna said showing the officer her fake badge. The man looked at the badge looking for any sign that she was lying. When he saw none he reluctantly agreed to let them through.

"Hang on... Who's your friend hiding back there?" The officer said gesturing to Sam.

"That's my partner agent Jones."

"Can I see some ID?"

Sam held up his fake FBI badge for the officer to see. The man nodded and let them through. When they approached the bodies Sherlock began doing Deanna what said as 'his thing.'

"No grown adult could've done this."

"Grown?"

"Yes grown. I think it was a child who did this. The wounds are too small to have been caused by an adult."

"What do you think we're dealing with here?"

"I don't know yet, I need more information."

Sherlock scanned all the bodies who'd been found dead in the cemetery. Something just wasn't adding up. All the evidence showed that it had to have been a child that had done it but not even one victim had a trace of the child's DNA. Perhaps a shapeshifter? No, DNA would've been found.

Each body had been attacked in an almost identical way but no evidence had been left by the attacker on the bodies. How strange.

"So Sherlock... What do you think did it?" Deanna asked.

"I can only rule out what it wasn't. It wasn't anything with a corporeal form. It's likely that a ghost caused this but it could've been something else."

"A ghost of a child? Why would a child's ghost murder all these people?" John asked from behind.

"Well I believe finding out who the child is and how they're connected to these people will be a step in the right direction."

Inside the rundown motel room which they were staying at the only light that could be seen was that coming from their laptops. As they researched the only sounds that could be heard was the clicking of keys and the tap dripping on the other side of the room. Deanna was looking through the victims files that the police had. She'd managed to hack into them remarkably quickly. Sam was looking at the lore while John and Sherlock were looking through whom the child could've been.

"Hey I think I found something!" Sam yelled.

"What is it?" Deanna asked without getting up.

"I think I've worked out what sort of ghost we're dealing with here."

"Well don't leave us in the dark about it! Spill."

"Alright, hold your horses. I think that what we're dealing with is a myling."

"What's a myling?"

"A myling is said to be the ghost of an abandoned child."

"What makes you think that we're dealing with one?"

"Let me finish!" Sam yelled at Deanna. She instantly shut her mouth and waited for the rest of Sam's explanation.

"As I was saying a myling is the ghost of an abandoned child. According to the lore children who become mylings were left to die by their parents in a remote area. It is said that these children return as ghosts. Enraged and seeking revenge.

The typical story of a myling states that it wanders the night until it meets a lone traveller. Once the myling meets the lone traveller it jumps on their back and demands to be taken to a graveyard. It is said that as the traveller carries the myling it grows heavier and heavier as they approach the graveyard. This is said to be because a myling takes on a more human form as the traveller nears the graveyard. If the weight of the myling becomes too much to bear and the person bearing them doesn't go all the way to the graveyard it is said that the myling will kill the traveller."

"What happens if the traveller makes it all the way to the graveyard?"

"It depends on the legend. Some say that if they make it all the way to hallowed ground the myling will pass on. Others say that the victim will never make it as the weight of the myling is too great and they sink into the ground."

"Is that all mylings want? To be put to rest?" John inquired.

Sam nodded.

"Then we should find out who our myling is and put them to rest." Deanna stated detrimentally. No sooner than she'd said that Sherlock had found out a possible identity for their myling.

A young boy had gone missing six years ago but his parents had never filed a report. Any parent would've when their child went missing, so it told him one vital thing. The kid had been abandoned.

"Thomas Jefferson. I think that he's our myling."

"Got any bones to burn?" Deanna asked.

Sherlock scanned the sight and oddly enough found out that the boy had been found dead in the forest two years after going missing.

'Yes! He's buried at Cambridge city cemetery. Plot 23."

"Alright. Let's light this son of a bitch!"

As they dug up Thomas's body they found it disturbing that the ghost had yet to show his face. Usually ghosts showed up pretty quickly after they started digging them up. Suddenly the wind grew a lot colder. They all knew what that meant. They were getting close to the bones. That meant that Thomas would come to stop them soon.

Their torches flickered on and off. Sam let out a small yelp when he turned to see the ghost of Thomas behind him.

"What are you doing?" The ghost asked him kindly.

"We're putting you to rest kid." Sam responded.

Thomas turned a ghostly shade of white which was actually very ironic giving he was after all a ghost.

"No! I don't need to be put to rest. Please stop." Thomas pleaded.

"Why?"

"I don't want to leave her."

"Leave who?" Sam asked.

The ghost had vanished. Sam looked over and noticed Deanna warming her hands on the fire burning in Thomas's grave. That must mean that Thomas had been put to rest, but there were still so many unanswered questions. Who was that girl that the ghost hadn't wanted to leave?

They were all getting ready to go to bed when the lights all simultaneously flickered out then back on. A massive gust of cold air enveloped the room, causing them to feel like they were frozen to their core.

"Why did you kill him?" The voice of a young girl asked. The voice sounded sad but clearly had a threatening tone to it. "We would've been fine and happy if those journalists hadn't tried to go out into the forest for a new case."

"Who are you?" Deanna asked the girl.

"My name is Chastity. Well that's not my actual name. I don't know what that actually is but I go by Chastity."

"Well Chasity..."

"He was my brother." She said in a sad tone.

"What?"

"That boy you murdered." She spat out. "He was my brother."

"Chastity... we didn't kill him we put him to rest." Sam said reassuringly.

Chasity wasn't buying it. To be honest Deanna didn't blame her for being mad, she'd do anything for Sam and it appeared that she would've done anything for Thomas. But something about Chastity just didn't make any sense. Why hadn't she been mentioned in the report? Surely if they'd found Thomas they'd also have found Chasity given how close she seemed to be to the kid.

"Stop staring at me! I can tell what you're thinking." She made her voice higher in a mocking tone "'Oh, why hasn't she been reported dead with her brother?'" She dropped the mocking voice and scowled at Deanna. "I didn't get reported dead because they never found me. Also according to the law I never even lived! I don't exist according to the law. Do you have any idea what kind of stuff that allowed my parents to do to me?"

Deanna shook her head.

"I bet you don't! Your parents loved you! Mine never cared about me, to them I was no better than the mud on the ground! I spent so long being tortured by them, every single day of my miserable life! Then they had Thomas. They loved him. They cared about him. They still tortured me, I didn't care though as long as he was safe. But after three years they stopped caring about Thomas. I saw the signs so I took him and ran away. I had to protect him, I couldn't let him suffer as I did."

"So you saved him." Deanna stated.

"Yes I did but fat lot of use that did! I tried to save him but he just ended up dying! No matter how hard I try to save him he dies."

"You were only a child. It wasn't your fault." Sam said.

"It was. I failed to protect him. You killed my brother you sons of bitches! Now I'm going to kill you."

Chastity lunged at them but they dodged out of the way. She laughed a sick laugh at their reaction.

"I'm a ghost remember? Merely dodging me once will do nothing to increase your chances of survival. I've taken down stronger." She said proudly before vanishing.

"Get the salt!" John yelled at Sam as he was the closest. Just before Sam could grab the it Chastity materialized and jumped up on his back.

"Try and kill me now bitches! Hit me and you hit your precious Sammy too."

Deanna who had picked up a salt filled shotgun appeared to be debating shooting Chastity. She wanted that damn ghost off her brother, she wanted Chastity gone. But shooting Chastity would mean shooting Sam as well. Deanna didn't know if she could bring herself to shoot her brother.

Chastity laughed again. "Oh look at you poor miserable thing. What's the matter? Afraid to shoot?"

"Get off my brother." Deanna growled.

"Or what?" Chastity taunted. "You won't shoot me and we both know it. You wouldn't hurt your poor little brother. So, whatcha gonna do Deanna?"

"Leave Sam alone. Please." She added the last bit pathetically. She didn't care, she just wanted Sam safe.

"I still don't understand. Why should I?"

"Because he's my brother. You know what it means to be a sister, right? Or did you forget that when you died?"

"You killed my brother, it's only fair." Chastity stated, though she seemed to doubt her statement just a little bit.

"Kill me, just leave Sam alone." Deanna pleaded.

"Alright, then." Chasity said indifferently.

Chasity disappeared from Sam's back and reappeared on Deanna's.

"No! Don't do this Deanna! I just got you back. I can't lose you again." Sam yelled at her through desperate sobs.

"Chastity, please just leave us alone." John said.

"No! You need to pay! After this bitch is dead then I'll leave you alone, but not a second before."

"Deanna!" Sam yelled.

"Please Sam, don't try and stop me."

"But-"

Sam was about to demand her to stop again but then he noticed that look in her eyes. The look that said 'don't worry Sam, I have a plan, just trust me.' If only Sam could. He didn't doubt that his sister had a plan but there was no guarantee her plan would work and he'd be damned if he was going to lose his sister again.

"Well Deanna I assume you know the drill." Chastity said.

"Yeah I know it. You demand that I take you to a graveyard so that you can reston hallowed ground. You'll get heavier as I go and if I fail to take you you'll kill me."

"You pretty much got the gist of it. Well, what are you waiting for? Giddy up!" Chastity said, grinning.

"Bye guys. Wish me luck." Deanna said waving to the others.

"Deanna, please don't do this. You'll die!" John pleaded.

Deanna winked at him and have him a cocky smile. "Relax! I'll be back by dinner time! You better have a burger prepared for me when I get back!"

"If you even make it back." John muttered under his breath. Both he and Sam knew that Deanna had a plan but that didn't mean that they wanted to go along with it. They both just wanted Deanna safe and sound. Sherlock was the only one who didn't try and stop her. He had faith in her plan and knew that she'd keep herself safe. Well, he certainly hoped.

"Stay safe sis." Sam said as she walked out the door.

"Anything for you Sammy." Deanna responded.

Sam smiled at her despite himself. He hated how far she'd go to protect him. She would do anything for him, including dying for him. Sam wished he had that kind of devotion to her. He decided that he'd just have to trust his sister and hope her plan worked out. If he interfered it was entirely possible that he'd mess it up.

They all just had to trust her, as hard as that may be.

Deanna carried Chastity on her back as she walked down the street towards the graveyard. Chasity was beginning to grow heavier but Deanna didn't mind. She wasn't too heavy for her to carry. She was lighter than a full grown Sam after all.

"Hurry up Deanna!" Chastity yelled from his back.

"I'll go at whatever speed I like Chastity. Calm your farm."

"But this is so slow!" She whined.

"If it gets you to hallowed ground where you can get put to rest I don't care!"

"You won't make it!" Chastity taunted.

"Watch me."

Deanna continued walking. She smiled when the graveyard came into sight. Chasity's weight was still growing and she was becoming a bit harder to bear but it didn't exactly matter. Chasity had seen the graveyard as well.

"Surely you know that you'll never make it Deanna."

"Oh, I will."

Chasity laughed but didn't say anything else. Deanna continued to approach the graveyard. When she was within metres of it Chasity's weight increased. She felt like a ton of bricks on Deanna's back, but pushed on. She had to, for her family's sake.

Just outside the graveyard Deanna's back was screaming at her to put down Chastity but she refused to. She had to get Chasity into that freaking graveyard for her plan to work. They both knew that the hallowed ground would do nothing to Chastity. But Deanna knew something Chasity didn't.

Once inside the graveyard Deanna set Chasity down onto the ground.

"You idiot! You do understand that even though you made it with me all the way here you're still going to die!"

"It doesn't matter."

"What?" Chasity asked cocking her head to the side.

"You heard me, it doesn't matter."

"Maybe not to you but how do you think that family of yours will feel seeing your dead body lying in the morgue?"

"As bad as your brother will feel seeing you threatening me."

"Who cares what my brother would think! He's dead!"

A small broken sob sounded from behind Chastity. She turned around and saw the ghost of Thomas standing behind her.

"But- but you're dead!" She choked out.
"So are you." Deanna pointed out.
"Not helping bitch!" Chastity yelled at her. She ran over to where Thomas stood and cupped his face in her hands as tears fell from his eyes.

"Do you really not care what I think?"

"No! No, it's not like that!" Chastity said frantically.

"I thought you wanted to save me." Thomas said in a broken voice.

"I am! Oh Thomas I thought I'd lost you!" She said pulling him into a hug.

Thomas pushed her away. Chastity looked upset but also confused.

"Thomas?"

"Don't touch me. Please Chastity, just go."

"But Thomas." She said as tears began to fall down her face.

Thomas shook his head. "Please Chastity just go. You're not my sister anymore."

"Don't be ridiculous Thomas! Of course I'm still your sister!"

"No you're not! My sister isn't a monster who kills people."

"Thomas-"

"Don't. Please sis. Just come with me. We can finally be at rest, we just have to accept it and move on."

Chasity finally nodded. "For you."

"Thank you sis." Thomas said as they both disappeared.

Deanna looked around the now empty graveyard. If she was being honest she hadn't expected her plan to work. She'd known that Thomas probably wouldn't be resting as long as his sister wasn't. Her attachment to him proved it to her. Since Chastity had been so attached to Thomas it was likely that she had something of his on her body meaning that Thomas's spirit wouldn't be at rest.

Deanna was relieved that the two spirits were gone. She smiled to herself. Job well done.

Back at the motel John and Sam were worrying about Deanna. What if Chastity killed her? What if demons got to her again? What if's there were so many of them. Sherlock who had faith in Deanna and believed that she'd be fine had set to the task of making tea. Sure it was absolutely terrible tea but it was tea.

When the door opened to reveal Deanna Sam and John let out a sigh of relief. Deanna smiled and glanced around.

"Thank god you're back!" John said.

"Yes I'm back, whoopty doo. Just one question though... Where's the burger I ordered?"

That night when Deanna went to sleep she was plunged back into a flashback of her time in hell. The last thing she wanted was to remember the torture she'd suffered at the hands of Alastair but she had no choice.

She knew the pain was coming and was anticipating it. But nothing came. No pain, no suffering just nothing. She looked up to see Castiel standing over her.

"Castiel?"

"Yes, my name is Castiel?" Castiel said, cocking his head to the side.

"What are you doing here?"

"I need to talk to you, somewhere heaven won't hear me."

"Why don't you want heaven to hear you?"

"They don't want you to know it, but you need to. If you don't get told she'll surely find you and kill you. I don't know why they don't realise that."

"Back up."

Castiel looked confused but don't question it and backed away. Deanna face palmed herself. "Not that sort of back up! It's an expression dude!"

"I see now." Castiel nodded.

"As I was saying... Who's she?"

"Lilith."

"And who is 'Lilith'?"

"The first demon ever created."

"Alright."

"Please Deanna, I know that you don't trust me but something big is coming and you four are in the middle of it."
"What's coming and what does it have to do with Lilith?"

"She's breaking the 66 seals."

"But why break the seals anyway?"

Castiel sighed. "Think of the seals like locks on the door."

"So the last one opens and...?"

"Lucifer walks free."

"The devil? No! There's no way that the devil actually exists."

"I speak the truth Deanna."

"Alright, say the devil is real. What happens if he walks free?"

"Hell. Lucifer cannot rise. Because if he does,"

"...Hell rises with him."
