A/N: My first Supernatural crossover fic! This idea's been in my head for a while now. Just a few quick notes:

(1) Deleted scenes from the movie will be included.

(2) There are spoilers for both My Bloody Valentine 3D & season 10 of SPN up to Soul Survivor. I'm going to be making an alternate version of the episode, though. You'll see what I'm gonna do. ;)

(3) Since Tom and Dean are both played by Jensen, Tom's hair is gonna be a bit lighter than Dean's, and his eyes are going to be a darker green. Just to differentiate the two of them instead of having them be twins.

Disclaimer: You know the drill by now. Enjoy!

Prologue: The Nightmare Begins

Harmony, West Virginia
February 14, 1999
"You sure you wanna go?" Aline Peverell called out as she fixed her black short-sleeved Batman t-shirt. "I could pick up your dad, and you and Sarah can go on a date or something."

She was living with her Uncle Eli Hanniger and cousin Tom. Ever since the fire that killed her mom (Eli's sister), Aline, ever since she turned thirteen, split time between Harmony and her hometown of St. Louis.

It was no secret to anyone that she wanted to live with the old man and Tom permanently. Tom was the only one who understood why that was. He was also the only one that knew about her nightmares about Hell. At first, he had been shocked that her father had done such a thing. Later, he took it upon himself to take care of Aline like she was his younger sister even though they were the same age.

"It's fine," Tom replied. "You wanna go. Sarah wants to go. I'll be fine."

Aline rolled her eyes while she walked over to Tom's truck after locking the door and climbed in the passenger seat. "We don't have to if you don't want to. Hell, you're the one that's driving, Tommy. Not me. Not Sarah. I'll live with staying as far away from the mine as possible and eating the leftover pizza in the fridge."

The town's mine belonged to Uncle Eli. There had been an accident there the year before, which led to a cave-in at tunnel number 5. The explosion that caused the cave-in had been ruled an accident after the police took Tom in for questioning, being the last person out that night. He revealed to the police that he forgot to bleed the lines. Some people blamed him for the fact that Harry Warden, the mine boss of the night, killed the miners that were trapped with him. Burke had been quoted as saying, "Warden killed those men to conserve his own goddamn air."

Now, Warden was in a coma, and everyone was saying there was no chance of him coming out of it.

Tom blamed himself for what happened, and he refused to go anywhere near that tunnel ever since.

But there was gonna be a party there that night, and both Sarah and Aline wanted to go. Plus, Aline's and Sarah's friend Irene convinced Tom to come.

Tom looked at her after buckling his seat belt, putting his hands on her shoulders and looking her dead in the eye. "I'll be fine. Trust me."

She skeptically looked at him for a few minutes before nodding and buckling her seat belt. He started the car and began the drive to his girlfriend's house.

The whole drive was filled with teasing between both cousins and the sound of Aline's latest tape filled with songs from different musicals, the both of them singing along to it. Uncle Eli had taken the both of them to see Jekyll & Hyde when it was in the area a few years back. Which was what they were listening to. "Facade" was one of the songs that calmed her down after one of her nightmares.

The moment Tom pulled into the Mercers' driveway and parked his truck, Aline unbuckled and scooched to the middle seat while Tom exited and walked up to the front door. Minutes later, Tom and Sarah both entered the truck, Sarah holding a six-pack of cherry Pepsi and Tom holding a six-pack of beer. Aline grinned.

"Sarah Mercer, you are my bestest best friend on the planet," she stated, taking the six-pack from her.

Sarah bowed as best as she could in the truck. "I do my best."

"That's not yours, actually," Tom teased, earning a playful punch from his cousin.

"Son of a pickle," Aline said.

"Prince William's buffalo."

Sarah rolled her eyes at their usual antics. The drive to the bar was pretty much the same as the drive to Sarah's house, except with Sarah either ganging up on either Tom or Aline much to the playful annoyance of the other. Tom and Aline sometimes ganged up on Sarah.

The two cousins kept Aline's nightmares between them, only to be talked about when they both knew for sure they were alone or Uncle Eli was asleep. Tom was always the one who woke up the moment he heard Aline thrashing around in her bed, sobbing and whimpering, and sang "Facade" until he was sure she fell asleep again.

Tom pulled into the bar's parking lot, and the trio piled out of the truck, Sarah tightening her ponytail as the three entered the bar. Aline spotted her uncle and his partner, Ben Foley, sitting at the counter talking.

"I was supposed to protect those men," she heard Uncle Eli say bitterly, "and they died because of my son. That's on me."

Ben looked over at Tom, Sarah, and Aline as the three of them walked over to Uncle Eli. Aline clenched her fists at her side.

"Dad," Tom began hesitantly, "we're here to take you home."

Uncle Eli looked away from him. "Can't you see I'm drinking?"

"Yeah, we can see that," Aline grounded before Tom or Sarah could say anything. The man knew her opinion on alcohol of any kind. He had been the second person she confided in about what happened with her asshole of an adopted father. "Why do you gotta do this to yourself?"

"To forget."

Aline clenched her jaw as Tom replied, "Yeah, well, it wasn't your fault."

"Yeah, it was." Eli finally turned in his seat to face the three of them, standing up as well. "And those men died because your father and your uncle trusted the wrong man."

Aline glared dangerously at her uncle, her clenched fist and every object hanging on the wall and glass on the counter shook violently while her eyes flashed black for just a second. She felt Tom's hand grab her arm behind Sarah's back, clenching it firmly as if he knew what she wanted to do to Uncle Eli.

"Eli," she barely heard Ben call. She didn't even notice him until he was standing right behind her uncle, his hand on his shoulder forcing him to sit back down on the stool. "We all make mistakes. Some more than others."

The statement infuriated her. It seemed like he was implying the murders were all Tom's fault, just like every single person in Harmony!

Sarah walked toward Uncle Eli after glancing at Tom, putting her own hand on his shoulder. "Mr. Hanniger, I think you should come with us," she stated.

Eli turned his head away, letting Ben answer for him.

"Sarah, Tommy, Ally," Ben said.

The three of them took that as a cue and walked out of the bar, but not before Aline punched the wall next to the door out of anger.

*~*~*~*SPN/MBV*~*~*~*

The party was in full swing by the time Tom parked his truck at the top of the hill overlooking Tunnel Number 5. Sarah was successful in her attempt to brighten the cousins' moods after their conversation with Uncle Eli and Ben, and the two cousins had gone back to teasing each other about random things.

At least until they climbed out of the truck on the top of that hill.

Aline noticed Tom's face paled slightly at the sight of the mine itself. She looked over at him with a look, which he returned with a forced smile. She knew he wasn't too happy about coming back to this hellhole, but she also knew he wouldn't complain about it if she and Sarah wanted to be there. Nothing Aline said to him would change his mind.

The six pack of cherry Pepsi was in Aline's hand, and Sarah's arm was wrapped around Tom's. The trio walked down to where Axel Palmer had parked his car. Loads of people knew Axel harbored feelings for Sarah, even though he already was dating Irene. Obviously, Sarah chose Tom, and Axel got together with Irene, but Aline noticed the longing glances he sent Sarah's way behind Tom's back. She had cornered him about it a few times, telling him Sarah made her choice and for him to live with it.

Because of that, their friendship sort of deteriorated. Sarah became the mediator between the two of them. Aline and Axel, along with Tom (after Aline confided in him what Axel was doing), were the only ones who knew about the real reason it happened.

"Hey guys," Sarah greeted as the three of them approached Irene and Axel. "Thanks for waiting." She let go of Tom's arm and went to give Irene a hug.

Aline noticed Axel smiling at Sarah, or, at least, Sarah's body, and she sent a glare his way that disappeared before Irene and Sarah could even notice it was there.

"Yeah, Axel was about to give up on you guys," Irene said as she hugged Sarah and then Aline. "But I knew you would come."

"Axel. Hey," Sarah said, just being friendly.

"Hey Sarah," Axel replied, sounding more like an embarrassed middle student than someone who had just graduated high school.

Sarah backed up against Tom, who instantly wrapped his arms around her waist. Aline grinned at her cousin's actions. Tom and Sarah had been friends since elementary school, but Aline remembered hearing Tom always talk about his feelings for Sarah when he turned fifteen. It had taken Sarah getting ditched by her date at junior prom for Tom to spill his feelings for her for them to get together. Now, a year later, they were still going strong, and they'd been voted 'Class Couple' in the yearbook by the entire class.

"Okay, so before we go in...snapshots!" Irene called out with a grin identical to Aline's. The blond slid off of the truck and grabbed her camera.

Aline watched as Tom smiled down at Sarah and had to force herself to not clap happily. Tom was always the happiest when Sarah was in the same room or general vicinity of Tom, and his eyes shined the brightest when his hand was in hers even when he was feeling guilty about the cavein.

"No," Sarah said. "I don't think so."

"Come on." She looked over at Aline.

Aline grinned. "Hell, you know I'm in," she responded.

"Let's do this," Tom said. Irene smiled as Aline skipped over to stand next to Irene.

"Because you two look so perfect together," Irene stated as she held her camera up.

Sarah wrapped her arms around Tom's neck, and Tom wrapped his around her waist and kissed the top of her head while Irene took the picture. Sarah blushed as both Irene and Aline cheered. After handing the six pack of soda to Irene, Aline ran back over and jumped up on Tom's back, and he grunted as she wrapped her arms around her neck.

"Goofy picture time!" she called with a big grin.

"Easy there, Batgirl. You aren't as light as you used to be," Tom teased. 'Batgirl' was another of Tom's nicknames for Aline, considering her love for both Batman and Batgirl. Her other nicknames for Tom included different variations of 'Superman.'

She teasingly huffed. "I'm pleasantly plump, thank you very much, Supes."

"I don't think so."

"Are you calling me a liar?"

"I ain't calling you a truther!"

Both Sarah and Irene laughed. Conversations like this between the two cousins were normal, and it was a bit of a relief to tease each other after the things the two of them had been through. Aline climbed off Tom's back before he picked her back up bridal style, grinning like a madman. She tilted his hat to the side and looked over at Sarah.

Her cousin's girlfriend was posing like a model, but with a funny face. Aline stuck her hand behind Sarah's head as bunny ears, did the same to Tom, and did blue-steel. Irene couldn't stop laughing as she took the picture. Aline, Tom, and Sarah laughed while Tom set Aline down onto the ground.

Once they calmed down, Sarah asked Axel and Irene, "So...you guys want one?"

Irene looked like she was about to say yes when Axel grabbed the beer off the truck and spoke first.

"No we're good," he grumbled. "Come on. Let's go." He started walking towards the mine.

"All righty then," Irene said.

The five of them walked toward the entrance of the cave, Aline walking next to Tom and Sarah. Aline watched as Tom began to slow his strides as they arrived at the entrance, and she knew he was afraid. She shared a glance with Sarah, and they both stopped him before they could go any farther.

"Hey," Sarah said, and Tom turned to look at her. "We don't have to go in there if you don't want to, Tom."

"My suggestion from earlier still stands," Aline pointed out.

Tom smiled at both girls after looking into the cave. "It's fine," he said gently. "Everybody's here, having a good time. We should have a good time too, right? And you both wanted to be here."

"Do you want to be here?" Sarah asked.

"Yeah. Yes. I want to be anywhere you are."

Sarah wrapped her arms around his neck while Aline backed away a bit. "I love you," she whispered.

"I love you too." He placed a kiss on Sarah's lips before handing her the flashlight that he had grabbed. "I left the beer in the car. Here. Take this. I'll go grab it and then catch up with you two."

"Want me to go?"

"No. Go ahead, have fun. You too, Ally."

Aline shook her head. "I'll come with you," she stated. "You go ahead, Sarah. If Palmer starts making passes at you, kick him in the nads."

Sarah smiled at the cousins and nodded before they headed back toward the car and Sarah headed into the mine.

"I don't need a chaperone, you know," Tom pointed out when they got close to his truck.

"I know. I didn't think you'd want to head in there on your own when you actually do." There was a comfortable silence between the two of them for a few minutes except for Aline whistling "Facade." Tom joined in while he went to grab the beer.

That was when they both heard a scream that sounded like Sarah's coming from inside the mine. Neither of them glanced at each other as they ran back toward the cave, Tom dropping the six pack on the ground. Once inside, she saw Sarah, Irene, and Axel running toward them. Sarah had a bloody handprint on her white shirt.

"Sarah!" Tom and Aline yelled at the same time as Tom grabbed Sarah and held her.

"They're dead!" Sarah cried out as she rested her head against Tom's shoulder. "They're all dead!"

Aline joined Tom in hugging Sarah before glancing at each other and then looking back to where they had come from. Aline didn't want to lose her best friend here, and she wasn't going to. Not now, not ever. Tom pushed Sarah to follow Axel, who was heading out of the mine. Both Tom and Aline took off running as Harry Warden crept closer.

"Faster Sarah!" she heard Axel yell from outside. "Faster!"

A few seconds later, they were outside and Axel was trying to get Sarah into his truck.

"Nononono, we can't leave Tom and Aline!" Sarah yelled out, trying to climb out.

Tom attempted to push Aline towards safety when Harry caught the both of them with the axe and threw them back.

"NO! TOM! ALLY! PLEASE COME ON!" she heard Sarah scream, but she couldn't get up. She was in shock. She moved closer to Tom, and they both watched helplessly as Harry threw an axe at Axel's truck, embedding it in the glass.

It was just about an inch from Sarah's eyes.

She screamed.

Tom and Aline got themselves up to their feet as they heard Sarah's screams. Aline's jaw and fists clenched in anger, but she watched with sad eyes as Axel pulled the truck away, taking her best friends with him. Tom then quickly grabbed Aline's hand, and the two of them took off running back into the mine.

She thought they were safe...until Harry swung at them.

Both cousins were good at dodging the axe as Harry swung it. She jumped to avoid it, but she ended up falling against a pile of wood, Tom falling within arm's reach.

This is it, she thought to herself as Harry neared the both of them. This is how it all ends. She glanced at Tom, seeing he thought the same. She scooted closer to him, preferring to lie close to her cousin.

Before Harry could hurt either of them, someone fired at him, splattering the miner's blood all over Aline's and Tom's faces. Harry fell to his knees in front of them, staring right at the cousins like he was memorizing their faces. Neither Tom or Aline looked away, both of their eyes wide with fear.

"Stay down, Harry," she heard Sheriff Burke growl at Harry.

The miner didn't listen. He pushed himself to his feet again and stood in front of the cousins.

"STAY DOWN, HARRY!" he called to him again.

Aline heard more shots being fired at the wounded Harry Warden until he vanished. Footsteps chased after Harry while the sheriff knelt down in Aline's and Tom's line of sight.

"Tom? Aline? You all right?"

Neither of them answered. Aline only scooted closer to Tom and wrapped her arms around his body, Tom doing the same. She didn't want to ever let go of Tom, knowing they had stared Hell in the face and survived.
