Two scientists in lab coats were walking through their testing facility in Cambridge. It was late at night and they were the only ones there apart from the janitor who just entered the room.

They were walking through, examining the monkey cages while the distressed inhabitants howled. Along the wall behind them were a number of rats and mice in cages- all of the animals squealing.

"What is up with them?" The first man asked.

"Something's got them riled up!" The second man chuckled.

"I'm just glad we've got something to offer people!" The first man said as they checked the cages.

"I'm sorry but it's a load of crap. Pure profit-driven crap!"

"Well this flu season... it's an epidemic!"

"Come on, it's no worse than last year. And if Niveus was really worried about the epidemic they'd be giving the vaccine out for free. This supposed new formula?"

"Well they say it's faster-acting!"

"Maybe it is but human trials this week?"

"Yeah it does seem a little rushed!"

"A little rushed. Have you even seen the new vaccine?"

"No?"

"Yeah. Neither have I!"

"I have!" The janitor stopped in front of the scientists and smiled, blocking their way.

"Who the hell are you?" The first Doctor sneered arrogantly.

The janitor laughed.

"I'm running the experiment!"

He walked towards the pair and stabbed the first scientist in the neck with a syringe, emptying the contents into him.

"Oh shit!" The second scientist yelled, rushing to his colleague who was on the floor.

"What the hell?" he asked in shock before he was backhanded by the janitor and sent flying across the room, smashing into some cages.

"Relax. You're part of it too!" The janitor smiled. He quickly scanned out the lab and when the door closed, smashed the access panel with his fist, trapping the two men inside.

"What are you doing?" The second doctor yelled as he smashed on the door. The janitor looked at him with an evil grin through the Perspex window as growling and snarling could be heard from the room.

The doctor turned and screamed, blood splattering over the walls and window as the janitor giggled, his eyes turning pitch black.

It was the Monday morning following the Quidditch Final win. Y/N and Hermione were sat at morning tea with their three friends.

"Worried about Sam still baby?" Hermione asked.

Y/N nodded. Sam hadn't turned up for Ghoul Studies the previous day and hadn't messaged Y/N either. To say it was out of character would be understatement.

"It's ok love I'm sure he's-"

Hermione was cut off as a luminescent white/blue ball flew into the Great Hall and stopped directly in front of Y/N.

"Come to the Roadhouse immediately boy. It's an emergency!"

It was Bobby. He sounded scared.

"Alright babe I'll be back as soon as I can!"

"Be safe my love!" Hermione smiled bravely as they kissed, Y/N nodded, transfigured his robes into jeans and a shirt, jogged out of the hall and, once out of sight, apparated.

"Be safe!" Hermione whispered as a tear fell down her face. Lavender engulfed her in a big hug.

—~—

Y/N arrived at the roadhouse. He was instantly pulled into a hug by Jo.

"Jo? Bobby what's wrong?" Y/N asked.

He looked around the roadhouse- Jo, Ellen, Bobby, Ash, Jodie and Pam were here. All were sad and worried.

"Is this about Sam?"

Jo broke down in tears and gripped Y/N tight, crying into his shoulder. Y/N paled and rubbed her back.

"No... no no don't tell me-"

"He's alive, far as we can tell!" Bobby said gruffly. He handed Y/N a note. Y/N read it out loud.

"We have Winchester. We will trade him for the Prophesied One. He comes alone or the hostages die. 2:00pm Today Niveus Chemicals, Cambridge. The Knights of Merlin"

Y/N checked his watch.

"11:00am. We have three hours. Bobby is there a Floo that gets me close?"

Ellen snapped at Y/N.

"It's a trap. You are not going alone!"

"They have Sam, they have hostages, yes I am!" Y/N snapped back. There was a tense stand off momentarily until Ruby came through the Floo.

"Y/N!" she exclaimed happily and rushed forward, hugging him. Y/N hugged her back.

"What did you find Ruby?"

"Nothing Good Bobby!" Ruby released her hug and smiled wiping her eyes.

"The place is infected with Croats, at least twelve Knights. They have Sam bound in the northern building and thirty hostages in the southern one. The whole place is warded stopping anyone from exiting."

"Balls!" Bobby snapped.

"Ruby will you please tell Y/N he can't just walk in by himself and give himself up. It's suicide!" Ellen pleaded.

"No you can't Y/N. They would take you, kill Sam and the hostages. You can't trust the Knights" Ruby was almost begging Y/N not to go.

"Of course I don't trust the Knights but what choice do we have?"

"Split into two teams" Ruby replied quickly as she magically drew up a quick mudmap.

"This is a large facility but as far as I can tell everyone else is dead. Sam's in a locked room with a Knight in the northern building. The hostages are in groups of five, locked in rooms with Croats wandering the southern building and you have a dozen knights wandering the grounds as security."

Y/N and Bobby, far and away the most strategically minded of the group nodded along as the others watched. Ruby continued:

"If you approach from the main entrance, Y/N, take care of the Knights and a team can back you up from the west while another slips in from the north. Y/N, you and the western team free the hostages- I'll lead the northern team and get Sam out of there!"

Bobby smiled.

"It's as good a plan as we're gonna get!"

Y/N nodded.

"Alright I'll take Pam, Ash and Jodie- Bobby you Ellen and Jo back up Y/N!" Ruby said calmly but with worry in her voice. The others nodded.

"I don't like this!" Y/N sighed.

—~—

It was 1:55pm and Y/N was walking up the main drive of the Niveus chemical compound. He was suddenly aware of being surrounded.

"Prophesied One, how stupid of you to come. Now we take you to Lilith. We kill your friend, and we kill those hostages. We were always in-"

The twelve bodies were incinerated by an explosion of blue flame ripping from Y/N's body.

"Arseholes" Y/N said calmly as he jogged to the rendezvous point.

—~—

Ruby led Pam, Jody and Ash quietly into the northern building.

"No security?" Jody asked looking around nervously with her wand out.

"I don't like it either!" Ruby muttered back. "It's like we're being pulled into a trap"

—~—

Y/N reached the entryway where Bobby and the others were waiting.

"Alright kid you're here... the Knights?"

"Crispy critters!" Y/N chuckled.

"Excellent let's go!" Bobby replied, trying to open the front door to the southern building. One of Y/N's huge hands stopped it from opening.

"No!" he said calmly.

"Kid we don't have time to-"

"No, Bobby. I'm going in not you three. For whatever reason I'm immune to Croatoan. You're not. You get bit, stabbed, slashed you turn or die. I don't! This isn't up for debate. You wait here!"

"He's right Bobby!" Ellen sighed.

"I'll be back as soon as I have some hostages. Don't come in no matter what you hear!"

Jo rushed Y/N and hugged him tightly, whispering:

"Good luck Y/N!"

—~—

Ruby and the team approached a sealed room in the middle of the northern warehouse. Ruby opened the door and saw Sam bound and gagged on a chair.

"Mmhhmm mhhmm mmhhmm!" He tried to moan as they entered.

Avada Kedavra

Ruby fired the killing curse, hitting the knight who was hiding behind the door, his body hitting the ground with a thud.

"Arsehole!"

She walked up to Sam and removed his gag chuckling:

"I would have tied you up happily Winchester. You only had to ask!"

As she got his gag off Sam screamed.

"No. It's a trap he's not a-"

The four rescuers were thrown back and pinned to the walls of the enclosed room, a dark laughing filling the air as the knight rose to his feet.

"Foolish traitor. Killing curses don't work on demons!"

—~—

Bobby and the others paced nervously. They could hear periodic screams and explosions from inside but nothing else. They held their wands as the door suddenly opened. Y/N burst through. Five people were with him.

"Go these people will help you. Go!"

He disappeared back inside.

—~—

"You idiots. So predictable. One little hunter goes missing and the rest flock like lemmings. You've made our job so much easier" the demon sneered.

"Just let them go! You've got me!" Sam snarled.

The demon walked up and slapped him hard.

"This isn't about you Winchester! This isn't even about the Prophesied One. This is about her"

The demon turned to face Pam and giggled disturbingly.

—~—

Y/N reappeared for the fifth time. Each time with a group of frightened people.

"One more group to find. I think I've got all the Croats!"

He was suddenly pulled back inside as the door shut. Bobby heard him yell.

"Nope missed one!"

—~—

The demon approached Pam who was still bound to the wall and giggled again.

"This was a seal. A seal that had to be broken. Thank you all for your help."

The group gasped. Pam's mouth opened noiseless but in agonising pain. The demon had plunged a long knife into her stomach.

"The Death of the sightless Vision was a Seal. Thank you for your sacrifice" the demon giggled in a sing-songy voice before disappearing.

The others were instantly released from the wall, hitting the ground hard. Sam was freed by Ruby as Jodie rushed and pulled the knife out, Pam gasping in pain, yelling with a concerted effort:

"Y/N!"

—~—

Y/N emerged from the doorway with a group of five people and a blue Phoenix perched on his shoulders. He put his hands on his knees.

"All the hostages saved. Croats are all gone. Let's meet the others and-"

He stopped as he heard Pam pained and begging in his head, calling his name.

"Oh no!"

He felt a pull and went with it, apparating to Pam's side.

—~—

Jodie pulled out the blade and attempted to heal Pam's stab wound. Nothing happened. She looked down at the knife.

"Oh no. It's a cursed blade. There's nothing I can..."

Tears fell down her face as Pam smiled a bloody smile and wiped her face with a bloody hand. Y/N suddenly appeared in the room.

"Pam? Pammy? No.. No... No!"

Y/N kneeled down as he roared a pained roar, Pam coughing in pain, before she rubbed his face with her blood soaked hand.

"Y/N... use...a...fucking....cond-"

Pam's hand fell to the ground. Her head dropped limp. The others cried. Y/N felt his heart fill with rage and hatred.

Pam was gone.
