Okay guys, Coldwave is my new recent ship and I love the idea of them raising a kid together….hence this series of one-shots revolving around this scenario.

I am now taking prompts for these one-shots and the gif sets available on my Tumblr ( tagged/coldwave)

Enjoy! Please read and review :)

This one-shot takes place about 6 months after the previous chapter, and the Flash and the Rogues are already an established part of Central City. The first season will be spread out over a longer period of time.

…..

Lucas bobbed his head quietly to the music playing in the bar. Saints and Sinners was their main hang-out when his Dad and Papa were having a small argument….now this one was only a small spat in comparison to the other fights that they had, but Len was still sulking in their usual corner.

Len leant over the bar and gestured for the bartender, "Give me another one….Ice cold."

Lucas rolled his eyes at his Dad, "You know you don't have to use cold puns all the time, right?"

Len smirked at his son, "But how will everyone identify me as the feared Captain Cold?"

"You mean apart from the fact that you're one of the most wanted criminals in Central City? Everyone knows your face!"

Before Len could answer, he turned around and smirked at a familiar face. "Well, well, well…If it isn't the scarlet speedster."

The young man, who didn't look very happy to be there, sighed. "We need to talk."

Len nodded, moving them over to a pool table. "You want anything? Beer, food? Pickled eggs here are fantastic."

Lucas nodded in agreement with this, offering Barry some of his fries. Barry shook his head, "No, I'm good. I need your help with a problem."

"Must be pretty desperate to come asking for my assistance, but I'll bite. What do you need?"

"Help transporting some people out of the city."

"How many?"

"Five…Five very bad, very angry people…who have powers."

"Powers, hmmmm? So you want me to what? Freeze the problem? Protect you from them if anything goes wrong?"

Silence.

Len continued, "First rule of business: always protect yourself. I'm not gonna help usher your enemies out of town."

As Len and Lucas moved to leave Barry alone, the young man stopped them. "Hey, they're not just my enemies. They're your enemies, too."

Lucas scoffed at this, "I doubt it."

"They will destroy Central City!"

"It's not my problem…." Sighed Len

"You said that you love it here. That this is your home. Your son's home!"

"I do and it is."

"Well, guess what? These people get loose, there won't be a city to love anymore. You won't be able to rob anyone if everybody's dead."

Lucas and Len glanced at each other, communicating silently until Len nodded once. "It's a compelling argument…" He got out a pen from his pocket in order to write something on a napkin, "…But if I'm gonna help you out I'll need something in return."

"Like what?"

Len slid the paper across, "This."

Barry's face paled slightly, "No…This is impossible. I can't do that!"

"Then we can't help you."

"There has to Snart-"Noticing that he was getting louder, Barry glanced around before lowering his voice, "-there has to be something you want that I can get"

Thinking to himself for a few moment, Len sighed. "Let me think about it…"

Without even waiting for an answer, Len gently ushered his son out of the door of the bar. Halfway home, Lucas glanced up at him. "…What did you ask him for?"

"…You don't want to know kid."

…..

Over the next hour, Lucas watched as his Dad thought quietly to himself. "I have been given a rare opportunity…" he whispered, "…the Flash can do anything, we could ask for anything…well, almost anything."

Lucas nodded, his eyes focused on his 'Captain America' comic. "What about our permanent records?" he asked, "It would make things easier for us…"

Len beamed at his son, "Excellent idea. No fingerprints…no match to any crime. Not that any of us leave fingerprints anymore. Amateur mistake and all that."

He practically leapt up from his seat, grabbing his parka and gesturing for his son to follow him. "Come on, we need to pay a visit to Star Labs."

…

Lucas stuck close to his Dad as they strode through the corridors, towards the main laboratory. As they got closer, they both heard Barry talking to someone.

"So, like it or not, Snart, with his cold gun, is the only one that can stop them if Cisco's transportation does not hold!"

Len then decided to make a dramatic entrance (much to Lucas's embarrassment). "Then lucky for you I figured out what it is you can get me…." The policeman quickly drew his gun, but Len only smirked, "Hello, Detective, nice to see you again. Caitlin, Cisco. I thought about your proposal. You want my help, this is what I want…." He began to stroll around the lab, "…Fingerprints, dental records, DNA, criminal records, family tree, everything there is in this world concerning Leonard Snart, Mick Rory and, if there is anything, Lucas Rory-Snart."

Silence.

Len continued, "I want it destroyed. All of it. At CCPD, online, everywhere."

"The brass on this dude…." Sighed Detective West, clearly finding this funny, "You really think we'd do that for you?"

Len glanced at Barry and smirked. Barry sighed, "I'll do it. If it's the only way, fine."

"You and me need to talk right now." Ordered West, striding out of the room as Barry followed on behind.

Silently, Len and Lucas glanced around, with Lucas examining all of the scientific equipment with interest.

After a while, Barry came back into the room and handed Len a slip of paper. "I'll do it…meet me at this address later on tonight."

Len nodded, smirking as he and his son left.

….

Later on that night Lucas and Len watched as a pile of files began to stack up in front of them. Quickly, the Flash came to a stop.

"I've deleted everything the CCPD, ARGUS, and the FBI had on you and your family, and sent a virus to erase every digital record of you guys online." He gestured to the files, "And this is every single piece of physical evidence the police had."

Len smirked, "Good."

Lucas grinned as a jet of gold appeared from a hidden alleyway, causing the Flash to flinch slightly and roll his eyes. Lisa Snart stepped out.

"I hear we're all going to be working together…." She crooned.

"That's right, Sis….Partners."

The Flash sighed wearily, "We need to get back to STAR labs. I meet you guys there…"

Lucas barely had to blink and the hero was gone. He glanced up at his Dad and Aunt, smirking at them. "I don't think he's happy with us…"

"That's an understatement Lucky…"

…

Needless to say, Caitlin was not happy to see Lisa. "Please tell me this is a joke."

"Oh, you were right, Lenny…." Lisa pouted, "…She is very uptight."

"I am not uptight…" she glanced at her friends, before amending her statement, "…You can't call me uptight."

Barry sighed, "Look, guys, we need their help if we're gonna pull this off."

"Why are you wearing your mask?" asked Caitlin, "Snart and his…kid already know who you are!"

"And we promised we wouldn't tell anyone…That includes my sister."

"Jerk."

"Train-wreck."

Lucas smirked at the shocked look on the Detective's face, "Don't look so surprised, Detective. We are men of our word."

"Yeah, you better be…." Grunted the man, "…Or I'm gonna make sure you're on that damn plane, too."

As they went off in their different directions, Lucas heard his Aunt begin to flirt with Cisco…and annoy Caitlin at the same time.

Brilliant.

…..

The group met at an abandoned warehouse, where a giant lorry was waiting for them. Lucas was helped into the back by his Dad who joined him, as the Detective and Cisco examined the vehicle.

"This is cool. Where'd you get this?"

"My uncle owns it. His company hauls frozen food cross country."

Cisco faced the group, "Okay, so I retrofitted the cooling system with the wheelchair's power source to create an energy damper."

Detective West frowned, "Which means what, exactly?"

"Basically, the back of this rig is being flooded with so much power that it's effectively creating a transient pulse strong enough to disrupt the meta-humans' powers, so we can get them to the airport and get them on a plane without them getting fresh on us. Technically, we need somebody with a Class A commercial driver's license to drive this, though."

At this moment, Lisa chimed in, "I can drive it."

The merry-group of do-gooders all stared at her, causing her to pout. "What? I have a Class A CDL."

"You do?" Caitlin didn't seem to believe her.

"We can't all be doctors…."

Len and Lucas smirked at this as Barry sighed, "All right, well, let's do this. Plane's gonna be here in two hours."

…

"Dad…" hissed Lucas as he climbed onto the back of the motorbike, "…they have Uncle Mark and Aunt Shawna in the back of that thing!"

"Don't worry about it Lucky, me and Lis have a plan…"

"Really?! What?"

"You'll find out…"

As Cisco reported on the dampener systems, the Flash strode up beside Len and Lucas. "All right…" he began, "….I'll make sure the roads are clear. Do not stop for anything."

Len nodded, "Let's move out…After you."

The Flash smirked and rolled his eyes, before zooming off. The journey had begun.

Eventually, the group pulled up in a familiar location. Lucas hopped off of the bike and glanced around, "Ferris Air? I thought this place got shut down."

"It did…" began Barry, "…One of their test pilots disappeared."

Detective West strode over, "So what's the plan? I want to get this over with."

"It should be here any minute…."

Barry and West chatted quietly for a bit, before West stormed away. Sensing that the plan wouldn't be arriving any time soon, Lucas trotted over to the lorry and climbed up the steps leading to the driver-side door…his Aunt and Cisco were talking, and Cisco seemed a little flustered.

After tapping on the window, Lucas watched as Aunt Lisa opened the window and smirked, "Were you two flirting?"

"No!" "Yes…"

The pair glanced at each other as Lucas giggled, "Dad won't be very happy…." He chimed, giggling further as Lisa mock-swatted at him.

"Why don't you go be a pest somewhere else?"

Knowing that she was only teasing, Lucas nodded and ran back to his Dad.

Len sighed, ruffling his son's hair as the kid ran up. "Your ARGUS friends aren't very prompt…."

"Maybe that's why they've never been able to catch us!" giggled Lucas, smirking as Barry rolled his eyes and grimaced at the pair.

Caitlin pointed into the distance, "Look, there it is."

Suddenly, Cisco came running up to them, "Guys, guys, we have a problem. The damper's fluctuating. The rig's losing power. I don't know why!"

"Wait, can you do something?!"

"I'm trying!"

"Oh, God." Gasped Caitlin as lightning flashed across the sky, dangerously close to the plane.

"Mardon…" sighed West

A bolt of lightning then struck the wing of the plane and sent it crashing into the distance, where it erupted with an explosion of fire. Seconds later, the back of the lorry flew open to reveal the prisoners.

"Trip's cancelled!" chuckled Mark

"Take your last breath!"

As one of the prisoners turned into green, probably poisonous, gas, Len pushed Lucas to hide behind a car, where they watched as the Flash and his team fought the prisoners….well ex-prisoners.

"Dad! We need to do something!" cried out Lucas, flinching as the sky turned stormy and lightning struck the ground.

"Calm down Lucky…this is all part of the plan."

"What?!"

Lightning sent the Flash crashing to the ground, and Simmons (who could shoot lasers from his eyes) began to walk over. At that moment, Len dashed out of his hiding place, stood in front of the Flash and fired at the man…

As his face burnt, Simmons was only able to turn around to face Mark and the others…before collapsing dead to the ground

Len kept his gun pointed at Mark and the other prisoner, "How about we call tonight a tie?"

The other prisoner's eyes flashed red…before another gun was pointed at his head. "I'd power down if you don't want me to melt your face." Ordered Lisa.

"Let's all go our separate ways…." Continued Len, "…My name is Leonard Snart."

Mark rolled his eyes, "I know who you are….I've babysat your kid about a dozen times."

"Not without teaching him a new swear word, but I digress…Just remember who it was made sure you didn't get thrown on that plane bound for nowhere."

"You're just letting us go?" Mark didn't seem convinced, "…Why'd you shoot that guy?"

Len smirked, "He owed me money."

Mark couldn't help but smirk at this, "Mmm. What? Want a 'thank you?'"

"Of course Mark, we are trying to teach Lucas good manners after all."

There was silence for a few moments, before the other prisoner spoke up, "Thank you."

"You are so very welcome."

Mark rolled his eyes and waved at Lucas, "See ya around kid."

Lucas grinned and turned to follow his Dad over to where the Flash lay on the ground, groaning in pain. "You sabotaged the truck, didn't you? Why did you let them escape?"

"Because now they all owe us…" answered Len, "…And something tells me they'll be a lot more use to me as part of my rogues than rotting away in the North China sea."

"You gave me your word."

Both Len and Lucas laughed. "It's true, I did…." Chuckled Len, "…But here's the thing. I'm a criminal and a liar, and I hurt people, and I rob them….What did you expect me to do? Not be what I am? I saw an opportunity to turn things to my advantage, and I did. Who you're really mad at is yourself. This is on you, Barry."

"Then why didn't you just kill me?"

Lucas piped up at this, "Well, I guess you owe us one now, too!"

Len grinned, getting on the bike. His son rested on his knees and his sister was behind him, "Good luck with all of this…." He chuckled, "…I'm actually really excited to see how it all turns out."

With that, they zoomed away from the hanger, with Lucas whooping in glee…they won!
