The tone of the high pitch beeps which radiated in the air had slowed to a steady rhythm.

Jared couldn't stop staring at the wide screen which displayed his pulse and blood oxygen levels. His BPM had dropped significantly in the past hour which worried both Dean and Jared.

Jensen had a large tube shoved down his throat which pumped oxygen into his lungs since he wasn't able to breathe for himself. His mind was no longer active as he had slipped further into a coma after the seizure.

"I can't heal him, I'm sorry," Castiel said as he removed the two fingers he had planted on Jensen's third eye.

"What do you mean you can't heal him?" Jared panicked.

"There is dark matter running through his body. It seems to be targeting his main organs and is slowly disintegrating them. When I use my grace, I just make it worse," Castiel took a step backwards with an apologetic look in his eyes.

"Then how do we get rid of this so-called dark matter," Jared rushed, but was interrupted by the sound of choking and spluttering from beside him.

Jensen body began to twitch again but it wasn't like before. This time a purple glow radiated from underneath the blankets as it slowly made its way up Jensen's legs. It was dimmed enough to look at it, but they were all still baffled.

The ground began to shake with intensity as the building they were in wobbled from side to side. Jared reached his arms out to his sides to find balance but instead fell backwards and smashed his back into the hard wood floor.

Dean stretched his arms out for Castiel as the angel did the same. They wrapped their arms together and held on with all their strength to stay sturdy.

An ear-piercing SMASH came from the large window beside them as it shattered to pieces in the pattern of a spider web. The shards of glass dropped several stories as it smashed into even smaller pieces.

Jensen's body had suddenly begun to glow a mix of purple and light blue. It made its way to his chest as the earthquake became more and more intense.

A swirling cloud of blue and purple intertwining light puffed out of the corners of his mouth and gathered in the shape of a ball in the middle of the room. It twirled and mixed but the colours never faded.

Suddenly, the cloud imploded then shot outwards as it evaporated into the air. Jared, Castiel and Misha were all on their knees as the tremors had made it impossible to stand up.

"What the heck was that?!" Dean yelled as the tremors settled down to feel like a slight shaking sensation.

"That was the dark matter reacting to my grace," Castiel mumbled.

"Seriously?" Dean looked at Castiel with wide eyes.

"That's what's killing Jensen?" Jared said terror in his tone.

"Unfortunately, yes. His body's defence mechanism saw my grace as a foreign substance and its job was to get rid of it. It definitely did its job. Thankfully it also got rid of some of the dark matter in his body, but not enough to make a huge impact," Castiel said as he stood up hesitantly.

"Then how do we get rid of it? For good?" Jared asked as he looked at Castiel with his adorable puppy eyes.

"Unless you have a grace extractor or some kind of dark matter expeller then I don't think I can help you. A human body was not made to house elements of this sort. There's no saying what effect it will have on him," Castiel said as he inspected Jensen.

"What do you mean? Will it kill him?" Jared's chest rose and fell at a rapid pace.

"Not necessarily. It definitely has to ability to kill him, but if it doesn't then it would mutate his cells which can be unpredictable," Castiel placed his palm on Jensen's chest and shut his eyes.

"So like, you mean he could turn into one of those mutants from X-Men?" Dean asked as he waved his finger in the air without purpose.

"I don't get that reference Dean," Castiel shot his glare towards Dean just in time to see him roll his eyes with a dramatic flair.

"Wolverine, Phoenix, Professor X, Magneto… Mystique! Any of those names ring a bell?" Dean gestured in annoyance.

"No Dean," Castiel stared at Dean until Jared interrupted.

"Can we please stop bickering and come up with a plan to save my best friend," Jared's voice was full of sorrow as a tear created a pathway down his cheek.

"Yeah. Jared makes a good point," Dean spoke softly with a guilt-ridden tone.

"Hey Cas, didn't you use that grace extractor thing on Sammy to use as a tracking spell for Gadreel a few years back?" Dean asked as he took a step closer to the bed.

"How did you know about that? Did Sam tell you?" Castiel questioned.

"Doesn't matter how I know; we have more important things to worry about now. Now where did you leave the grace extractor?" Dean raised his tone which caused his voice to sound grainier.

"Somewhere in the bunker. Except it's back in our world. We can't use the tools here because," Castiel's sentence was cut short.

"Everything here is a damn prop," Dean scoffed as he directed his attention towards Jared with a disappointed look in his eyes.

"So, what do you suppose we do then Cas. Got any bright ideas?" Dean stared wide eyed at Castiel.

"There's nothing else we can really do. Unless you have 2 archangels in this world willing to help extract this dark matter then we'll just have to wait it out and hope Jensen is still himself if he wakes up," Castiel looked apologetically at Jared.

"If?!" Jared whispered with the intent to yell.

Dean creased his eyebrows as an idea popped into his mind, but he couldn't quite reach the solution.

"Hasn't this happened before on like that tv show from DC? What's it called?... Speedy? No. The Blur? I don't think so… Um.. OH! The Flash!" Dean's face turned into a wide smile as if he had accomplished something extraordinary.

"What do you mean?" Castiel looked at Dean confused but a little intrigued.

"Yeah, the uh new season. It deals with these humans or objects that gained powers from dark matter and the nerdy dude with Sam's hair who works at some science lab, finally created a cure and they administered it to some shark dude and some messed up guy with a psycho daughter and it worked!" Dean continued to rampage on about his knowledge of The Flash.

"So, do you think you could create something like that?" Dean asked with hopeful tone.

"That's a fictional television show. None of it is real. So this so called Dark Matter cure doesn't exist," Castiel said defensively.

"We're a tv show too and we exist," Dean tried to make a point.

"I guess if I could find what Earth or plain of existence these Flash people are on then we could steal one of their cures of at least get the ingredients for one," Castiel suggested.

"Great idea Cas, I wish I could've come up with that," Dean said sarcastically as he reached for his hat and placed it on his head.

"So Jared. You comin?" Dean glanced back at Jared who looked like he was struggling with the decision he had to make.

"Standing over Jensen's unconscious body isn't productive nor is it helping him, and we could really use an extra helping hand. Plus, this new world will be epic I can guarantee it," Dean make a clicking sound with his mouth which was accompanied by a wink as he waited in anticipation for Jared to join them.

A smile slowly but surely made its way across Jared's face as he nodded and took a few steps forward to join Dean and Castiel. "Jensen and I good friends of the cast of The Flash so I recon this'll be pretty cool. Plus, Jensen and I may have peed on Stephen Amell's parking spot not so long ago, so it's been a little awkward since," Jared began to feel more like himself as he bragged about the amazing pranks he and Jensen had previously pulled on the DC tv show cast.

"So how do we make this portal?" Jared asked as he followed Dean and Cas out the door.

"Crap I hadn't thought of that."
