**I thought this would be a great idea, so I thought I would write it. This will include spoilers from season 13 of supernatural, sooo if you are not caught up, or don't want it spoiled, you may want to wait and read this. -Jamie **
It had been weeks since Mary Winchester had been missing along with Jack in the other dimension. Sam and Dean had been trying everything they could to figure out how to get to them. From what they could find, it took a spell that they found in the demon tablet. Cas was working on trying to get all the ingredients together and ready to do the spell.
"Dean, what if the spell doesn't work. What are we going to do then," Sam said as he leaned back in his chair and rubbed the scruff on his face.
"It's going to work, Sammy. Have a little faith," Dean said as he rolled his eyes and got up.
Dean went to go towards his room, when everything started shaking. He gripped on the table that was near him, and looked around. "Sam!"
Sam started walking to where Dean was. He gripping on the door frame. "Dean! Is this-"
"An earthquake? We don't get earthquakes! We get fricken' tornados!"
When the shaking finally stopped, Sam and Dean stood up straight and looked at each other, before walking outside of the bunker. When they opened the door, there was a light blue light that seemed to be surrounded by water.
Dean looked at Sam and shrugged his shoulders. "Lets check it out." Dean said as he jumped into it.
"Dean!" Sam said as he hesitated to follow his brother, but did so anyways. When Sam's feet landed on the ground, he looked over to Dean, "Dean! You can't just jump into strange things like that!"
Dean stood there looking around, not familiar to where he was. "What is this? Is this like another dimension?"
"I think it is," Sam said as he turned around and the portal had closed. Behind it was a sign to Starling City.
The night sky was lit up with the lights of the city. Dean went over to one of the cars that was parked on the side of the street. He wasn't so happy Baby wasn't here, but he had to do something. Dean unlocked the car, and got inside and started hot wiring the car. Sam came around the other side and got in the passenger seat. They headed into the city, looking for anything they could see. Suddenly there was a red blur that went by the car, causing it to shake.
"What the hell?" Dean questioned as he tried to follow the light, but it had disappeared.
"Dean, I don't know what is going on here, but something doesn't feel right about all of this."
"Look, we will find a hotel to stay in tonight, then tomorrow we will do some digging." Dean said as he glanced at Sam, then back on the road.
When they found a hotel, Dean parked at the end of the lot, and went to get a room. When they got to the room, they both just sat at the ends of the bed, and looked at each other.
"So, what, we just stay here?"
"Just for the night, Sammy. Or until we figure out what the hell is going on." Dean said as he leaned back against the headboard.
Suddenly, the door busted open, and a woman walked in, with long brown hair, in a black suit. Sam and Dean stood up suddenly, with guns in hand. The woman moved her hand in a swift motion, and suddenly their guns were across the room.
"What the hell?" Dean said.
"Traveler's from a different universe. How cute," she said as she slung Sam and Dean to the side of the room. When they hit the floor, the both of them groaned.
"Look lady, I don't know what your problem is, but we just want to go home," Dean said as he stood back up.
"To bad you won't be alive long enough to go back," she said as she raised her hand up and clutched her fist, making Sam and Dean's heart, feel as if they were being crushed.
Suddenly, an arrow came through, and struck the woman in the shoulder. Her hold on Sam and Dean was released, and she took off running. They fell back down on the floor, taking a breath.
A man in a dark green leather suit, came walking into the hotel room, with a bow in hand. "All y'all alright," he yelled out with a husky voice and extended his hand out.
Sam took his hand and stood, as Dean stood on his own. "Yeah, yeah we are fine. What the hell was that?"
"That sure as hell won't like any demon we've ever faced," Dean said as he looked at Sam.
"Demon? Where the hell are you from? That was a meta," the guy in the hood said.
"What is a meta," Sam questioned.
"You're obviously not from here. Come with me, and we will figure this out."
When they got to the bunker, the elevator doors opened up into a large room, with green lighting, and a center stage area, where Felicity sat at her desk of computers.
"Okay great, you're back. Now, there is a-" Felicity paused as she stood in front of Oliver, and the two new comers. "Uh, Hi." Felicity looked at Oliver, "Are we just bringing home new people now?"
"Felicity, this is Sam and Dean Winchester. They are not from our earth," Oliver said as he went over to the stand that his bow sat on, and placed it down.
"Hi, I'm Dean. Felicity, thats a beautiful name," Dean said as he took Felicity's hand
Oliver cleared his throat and leaned on the table. "Yes, it is. Thats why I married her."
Sam chuckled as Dean raised his arms up. "Sorry about him, he, uh, he is immature sometimes."
"Anyways, I should call Barry. This is more of his thing anyways," Oliver said as he started pulling out his phone.
There was a sudden red blur once again, and a man appeared in the middle of the room, "No need, I was already in town." Sam and Dean, in shock, pulled their guns out and aimed at the guy that flashed by them. "Whoa, I'm a good guy," Barry said as he raised his hands up and took his mask off.
"How, how did you.." Sam stuttered.
"I'm a speedster. Was hit by lightening, got super fast speed, fastest man alive. You two never heard of me," Barry said as he crossed his arms.
"Barry, don't get offended. They aren't from this Earth."
"Hold on Robin Hood, what do you mean this Earth," Dean questioned.
"Okay so let me guess. That big blue swirling thing of water, was a portal to another earth," Sam said as Barry and Oliver nodded. Sam looked over at Dean. "Maybe one of those portals can get us to mom."
"Where's your mom," Felicity asked as she looked at both the brothers.
"Well, we were fighting Lucifer, and there was a portal to an apocalyptic world. Our plan was to trap Lucifer in this other place. But when we did so, he grabbed our mom and dragged her over there," Sam explained.
"Now we are just trying to find her."
"Lucifer?" Felicity chuckled, then realized they weren't laughing. "Wait, seriously? The king of hell?"
"Well, no. Technically a demon named Crowley was the king of hell."
"Now it's some other douche bag. Lucifer is just like a lost puppy. A lost, stupid, evil, asshole-ish puppy," Dean continued.
"Okay," Barry paused as he crossed his arms. "So you're trying to get to that earth where your mom and Luci the evil puppy are?"
"Exactly. Along with Jack, who is a nephilim," Sam said.
"A what?" Oliver, Barry, and Felicity all said in unison.
"Oh right, y'all don't know what anything about that. A nephilim is a human slash angel. Which happens to be Lucifer," Sam explained.
"Oh, Lucifer has a son. That's fantastic," Oliver said sarcastically.
"Well, he is actually a good guy," Dean said with a shrug. "Now, enough about that. What's up with the chick trying to kill us?"
"Some worlds have strict rules about crossing dimensions. She is a collector. She is going to want you dead now," Barry explained. "But we dealt with her before. We can talk to her, and convince her not to kill you."
"That's fantastic," Dean said frustrated.
"We need to get to Star Labs, and talk with the team."
Sam and Dean nodded, right before Barry grabbed on to them and started running towards Central City.
When they got to Star Labs, Barry stopped in the middle of the main room, and Sam and Dean stumbled to find their footing. Dean ran over to the nearest trash can and started throwing up.
"Next time, we can just drive," Dean yelled out before throwing up again.
Barry chuckled and looked at Caitlin and Cisco, who were sitting at the desk. "Sam, Dean, this is Caitlin, and Cisco. This is part of my team."
"Nice to meet you," Sam said as he shook their hands.
"Uh, Hi. Barry, didn't we just have a talk about letting strangers know your secret," Cisco asked as he raised his arms a bit.
"Cisco, they are not from our world. Somehow they came into our world and now Cynthia is after them."
"Oh yay. You're girlfriend is back," Caitlin said sarcastically as she sat back down.
"Okay, she is not my girlfriend. I wish, but not my girlfriend," Cisco said as he rolled his eyes.
"You can't blame him. She was hot," Dean said with a laugh and Sam hit him. "Dude!"
"Dude she tried to kill us! All because we came here!"
"Still hot," Dean shrugged.
Barry chucked and crossed his arms. "Well we gotta figure out how to get you guys back to your world before Cynthia comes back."
"Yeah she may be hot, but damn she is strong."
"Now, y'all said she is a meta? What is that," Sam questioned.
"Well, a couple years ago there was an explosion here that effected a lot of people in it's that," Cisco started.
"Like myself. That's why I have super fast speed. Because of the explosion and the lightening, i became fast as, you know, lightening," Barry smirked. "so where you come from, there's no metas, but there are demons? and Lucifer?"
"Yeah. It's literally hell," Dean sighed.
"We actually hunt any and every monster than goes bump in the night. Demons, shapeshifters, vampires, werewolves, angels, you name it."
"Thats cool," Cisco said excitingly.
"No. Thats not possible. All those things are just fairy tails," Caitlin said doubly.
"Yeah well, its real princess," Dean said.
Suddenly the ground started shaking again.
"What the hell is this," Barry yelled out.
"Are we having an earthquake," Cisco questioned, gripping on to the table.
"This is exactly what happened when the portal came to take us here. Maybe it's the one to take us back," Sam said as he started looking around.
Suddenly the portal began to appear on the security footage on Cisco's computer. "Well, it was nice meeting y'all but looks like that's our ride!" Dean said as he grabbed Sam and started running outside, with Barry, Cisco, and Caitlin behind them.
"Maybe we will meet again one day," Barry said when he caught up to Sam and Dean.
"Maybe," Sam said with a short smile as Dean and himself jumped into the portal. The portal closed shortly after.
"Monsters? Yeah right," Caitlin huffed and walked back inside with Cisco and Barry behind her.
