🎶: 'Slipped Away' by Avril Lavigne

___________________

Sam drove the Impala, Dean didn't want to get in the way of his vengeance determination... Even though he constantly felt that the car was going to crash.

His hands firmly gripped the steering wheel, completely in rage but more with concern. Sam wanted you safe, more than anything.

They searched for weeks, nonstop, trying to find when Lucifer was holding you captive. They couldn't find out what was his reason to take you, what was the whole point?!

But it didn't matter.

You were taken and there was not a single sign of your existence anywhere... Until today afternoon, when Sam received a tip of screaming from an old house near the outskirts of town.

It was a half an hour drive, Sam didn't waste a second and sped through as fast as he could without killing himself and his brother.

"Sam, don't you think we should think our tactics through before facing Lucifer? I mean, he is the devil and he's an ass," Dean said but Sam's attention didn't divert from watching the road ahead.

"We'll deal with him like we always do. He acts smart and tough but he really doesn't have anything," Sam replied but Dean frowned. "Not normally, no... But he's got Eugenia now," Dean pointed out, "And it could turn bad."

Eugenia Flanery. Sam calls you 'Gene', it's his nickname for you, given that you love your torn jeans. Sam loves a good pun.

He loved your presence, your voice, your views, your smile, your eyes, your hair... He basically loved everything about you.

And you knew it.

What's more is that on one side Sam searched for you non stop, torturing himself for not finding any lead for such a long time, and on your side of the story, you just feel like he really doesn't care and all that appreciation towards you was just a fling.

"Okay take the next left then the following right and we should reach the house," Dean instructed, while examining the GPS map on his phone.

After much convincing, Dean sat in the passenger seat being the navigator. Sam felt as though being the one who's drives to the place would channel his inner anger and frustration somehow, leaving him a little satisfied that he has done something  more than doing research.

*****

The Winchesters walked inside the house, armed with weapons that can cause some serious damage to an arc Angel, or atleast would him enough to let you escape.

They listened for a sound, nothing significant or of importance could be-

AAAHHHHH!

The blood ran cold in Sam's body. He recognised that scream for help, it couldn't be anyone else than you.

He ran towards where he was sure that the sound came from. Dean followed his brother, alert to make sure that Sam doesn't make any stupid choices and barge into the room.

"HELP ME! PLEASE!"

Sam flinched, hearing you yell out in agony. "Dean she's in there, we have to help her out," Sam whispered fiercely and Dean nodded slowly, hoping that this would go-

"SAMMY PLEASE!"

Sam barged in, he couldn't stand hearing you shout his name. Dean rolled his eyes then furrowed his brows while looking around the room.

It was large space but the weird part was that you weren't anywhere to be seen in-

"Thing one and Thing two, what a lovely surprise!"

Sam and Dean looked back to find Lucifer standing there with a grin plastered on his lips.

"It must be my birthday, with two Winchesters and already having hold of their little gal-pal," He said and smiled smugly then swiftly flicked his wrist to throw Sam to one side of the room. He repeated the same thing with Dean.

His smile disappeared. He looked at the boys with hatred and disgust, but mostly with annoyance. "You guys don't stop yeah?" He said and clenched his fists, making Sam and Dean choke and struggle  to breathe.

"Now if you'll  excuse me, I have things to finish," He said then his eyes glowed bright orange, as if fire danced within them. The Winchesters' weapons melted right before their eyes and they looked at the gooey metal lumps with fear and concern.

Lucifer walked out of the room and they guys got their ability to breathe again. "That... That was my favorite pistol," Dean commented sadly and Sam looked at him with disbelief.

They got up and rushed out of the room, following Lucifer's path. They got a hold of a few sharp metal rods and fire pokers that could do some pretty good damage... at least scratch the enemy.

Well it's better than nothing.

There was some sort of chanting happening a few rooms over. Sam and Dean looked at each other with confusion then slowly entered.

It was dark, a light emitting from a figure in the centre. It definitely seemed like Lucifer and Sam wasn't happy about that at all.

There was groaning... someone in pain.

The Winchesters approached the people in the room, only to be faced with the go reigning reality that you were tied up to a post with blood dripping from your temples and your clothes completely soaked and dirty.

"You both really need to learn to give up and call it a day," He said with a raspy voice and Sam held onto his metal pole tightly.

"We don't want trouble, we just want Eugenia back alright?" Sam talked calmly and Lucifer chuckled. "But you don't realize that there's the problem right there. I can't give you Eugenia, she has something I want," He said then clenched his fists and straightened his back.

The whole room lit up, he was glowing bright with his wings showing being him. Sam and Dean glanced at each other, waiting to see how this plays out.

They started to back away as their enemy grew stronger. "This isn't going to end well!"Sam exclaimed while covering his ears from the high pitched  ringing noise.

Dean did the same and crouched, "You can say that again!" Lucifer grinned and raised his arms out ready to attack the Winchesters but-

"HEY douche bag!"

He turned around, his powering up ending abruptly, and looked towards you. You took a deep breath to steady your breathing then looked at him with confidence.

"I'm special to you and you need me right?" You say and stand up, leaving him shocked by seeing you free from the handcuffs, "Staying with the Winchesters, you learn a few tricks."

You walked up to Lucifer then punched him in the jaw. He stumbled back,  holding his face then looked to you with eyes squinted. "There's only one thing that can fix this," You state and grabbed a blade that was laying on a table.

You gripped it tightly and looked at the boys with tears in your eyes, "Here's to a better life..."

Lucifer started to storm towards you but you stabbed yourself in the chest with the blade.

Everyone froze, not expecting that to take place. You gagged, spitting and coughing up blood then falling back and collapsing, going unconscious... sadly, forever.

It happened so fast, no one reacted with doing anything to help. "No, NO!" Lucifer yelled then looked back at the boys, breathing heavily.

"This was fun I'm but I have to go-"

WHOOSH!

And he was gone... leaving the boys in extreme rage.

"SON OF A-"

"GENE!" Sam shouted and rushed to you. You had your eyes shut, hands on your wound. Blood spilled from your mouth and Sam couldn't accept what had become of you.

"W-Why? Why did she do that?" He questioned, tears streaming down his face. Dean looked at your still body sadly, trying to fight the tears in his eyes.

"Sam... I think she has something that she never told us about, some sort of power I guess," Dean stated, "Lucifer wanted her for a reason, and not just to get to us."

"Dean... We need to put her to rest," Sam said as he stood up and wiped his eyes, "We have to get the hunter's-"

WHOOSH!

The boys looked back, Castiel approached them with a jog. "Dean, Sam... You  were not aware but Eugenia possessed powerful capabilities, that Lucifer wanted to get a hold of," He explained in a rush.

The Winchesters looked at each other, eyebrows furrowed. "What?! How do you know?" Sam questioned.

"The Angels... They're talking about her... passing away," Castiel glanced at your body sadly, "They realized that Lucifer wanted her essence to recharge his potential. That's why he fled when she stabbed herself. He didn't have her power anymore."

Dean rolled his eyes, "Cas just cut to the chase and tell us what power-"

"Restoration... She had the power to restore beings to their full power and no capability."
