Note, this is not a slash fic. Not that I'm opposed to male-male pairings, but this fic follows canon, and Barry is straight. I like to read the occasional Coldflash fic sometimes, but I also think there aren't enough fics where Barry and Len interact in a normal, non-romantic way. I just didn't want anyone to mistake their interactions in this chapter for flirting. They're just frenemies in this story.

This chapter is the reason I wrote this story. I've wanted to write this specific scene since season one. I've been dying to see it ever since I found fanfiction, but no one ever wrote it. I'm super glad now that I did because it hints at a rare pairing I've always wanted to see.

Who's Scarlet Now?

Len was just itching to pull a heist. Ever since getting sprung from prison, he had been dying to start planning a job. He had promised Lisa he wouldn't, though. She didn't want to see him get put away by the Flash again.

Len wasn't too worried about that, though. Barry had only put him away the first time because Len had killed his own father. Len knew Barry wouldn't put him away for a simple heist. Barry didn't have the balls. Nevertheless, Len had reluctantly agreed to be a good boy for the time being, for Lisa's sake.

In Len's case, being good meant hanging out at Saints and Sinners, getting drunk off his ass. Granted, Lisa didn't want him hanging out at this bar anymore either. She thought it was a bad influence on him. He didn't care, though. He had taken a break from pulling heists for her. Getting drunk at Saints and Sinners wasn't a big deal by comparison.

Little did he know, that would be difficult for him tonight. Len had only taken a sip of his first drink when he looked over and saw something that made him nearly spit his drink out in surprise.

Barry Allen, of all people, was on the other side of the room.

Barry had come to Saints and Sinners before, of course. He only came here, though, when he needed to speak with Len about something—or more like beg him to do something for him. For a moment, Len thought that's what this was. He thought Barry had just come crawling here to ask him for another favor. Maybe to give him another obnoxious speech about how there's good inside him.

He quickly realized, though, that that wasn't the case. For one thing, Barry wasn't approaching him. For another, Len had only just got here, and Barry looked like he had been here for a while. He was currently by the pool table, playing a game with Tito Scorsese, a regular at Saints and Sinners. Len didn't know Tito well. He had met him briefly in Iron Heights once when they were in the same cell block together. Len knew one thing, though.

Tito wasn't exactly the type of company Barry usually kept.

Looking closer at the pair, Len could easily see they weren't exactly friendly with each other. In fact, Tito looked rather pissed off as he watched Barry sink another corner pocket shot. They must have been playing for money. Tito rarely ever played just for kicks, and he wouldn't look nearly this pissed off if he wasn't currently losing a game he had put a significant amount of money on.

Tito was easy to read. Barry, however, was much harder. What the hell was he doing here?! Why would a goody-two-shoes like him be hanging out in a grimy low-life bar like this? Why would he place a bet against Tito, a guy twice his size who looked like he breaks knee-caps for a living? Len knew Barry could take care of himself, but still, it was like he was looking for a fight.

And then Barry smirked at him.

As Barry was leaning over the pool table, lining up a shot, he suddenly looked up at Len and smirked. That was when Len realized.

Barry was looking for a fight. Just not with Tito.

Len's hands clenched into fists. Barry had come here on purpose. He had come here, to this bar, in Len's territory, for a reason. He was making a statement, a rather aggressive one.

He was challenging Len.

Len took another large sip of his drink, his eyes narrowing as he looked at Barry, measuring him up. He wasn't going to rise to the challenge yet. First, he was going to read the kid, figure out what the hell his end game was here.

Why would Barry suddenly want to pick a fight with him? Because Len broke out of prison? If that were the case, the kid could just run him back to Iron Heights if it bothered him so much. Barry wouldn't play these mind games. That wasn't exactly his M.O.

Maybe Barry just needed to let off some steam. The kid had just had his ass kicked by that one dark speedster, after all. He had been out of commission for a good week because of it. Maybe after healing from that fight, Barry was itching to fight someone he could actually compete with, someone without his powers.

Or maybe Len was just reading too much into it. Maybe Barry wasn't here for him at all, which led Len back to his first question. Why here? Why this bar? Why would Barry—?

And then the little shit smirked at him again.

Okay. Barry was definitely here to start something. Barry didn't look away this time. He continued to smirk at Len as he raised his glass up to his lips, taking a long drink of his beer without breaking eye contact. Barry was trying to get a rise out of him. He was watching him, waiting to see how he'd react to him intruding in his bar.

What the actual fuck? Why?! What the hell was this kid's problem?! Why was Barry doing this?!

The more Len sat there, watching Barry play pool, the more pissed off he became. He wasn't going to rise, though. Nope. He would just sit here. He wasn't going to play Barry's game. Barry was probably dying for him to come over and confront him right now, which was exactly why Len wasn't going to do anything. He would just sit here. Keep a cool head. Let the kid come to him.

Then again, if he just sat here, allowing Barry free reign over his territory, what did that say about him? It would make Barry think he could do whatever the hell he wanted. Len couldn't just sit here. He couldn't just let it slide. He wasn't some pushover for the kid to toy with.

Shit.

What was he supposed to do?! Why was Barry doing this?! Why was Len letting it bother him so much?! The stupid kid's presence shouldn't have him this upset. So what if Barry was here? Len didn't have to let it spoil his night. He didn't have to let Barry get under his skin. He should not be this upset right now.

Len knew why he was upset, though. He was upset because he couldn't make any sense of it. Len needed to have an explanation for everything at all times, and right now, he had no explanation for Barry's behavior. He didn't understand Barry at all, and that bothered him. It bothered him a lot.

Barry was throwing him for a loop, and that pissed Len off.

"Lenny!"

Len jerked his head away from Barry to see his sister sitting in the bar stool next to him. When the hell did she get here?!

"Not now, sis," Len said shortly, turning his head back to look at Barry again.

Barry had gone back to his game, sinking another ball as Tito glared at him.

"What are you doing here?" Lisa demanded, "I thought you said you were done with this place."

"No, I said I was done with heists," Len said calmly, "Not alcohol."

Even though Len wasn't looking at her, he could tell Lisa was rolling her eyes.

"You know alcohol isn't the reason I don't want you coming here anymore," she pouted, "The people here are a bad influence on you. All your old prison buddies and criminals. I thought you were done with all this."

"It's just a drink, Lisa," Len glowered, "I'm not here to reconnect with old rogues. I'm just trying to enjoy a drink in peace."

"Is that why you're glaring at peach fuzz over there?" Lisa asked, raising an eyebrow.

"What?" Len snapped, looking back at her.

Lisa tilted her head towards Barry.

"You've been glaring at that guy since I walked in," she said, "I said your name four times before you even noticed I was here."

"I wasn't glaring," Len corrected defensively, "I was just…"

"You were glaring," Lisa persisted, "Now, are you going to tell me why? Or am I going to have to guess?"

Len looked away from her and took a sip of his drink.

"Drop it, Lis," he said flatly.

"Does he owe you money?" Lisa asked curiously, "Did he rat you out? Steal from you? Kick your dog?"

"I don't have a dog," Len said, rolling his eyes.

"Well, the kid clearly did something to piss you off, Lenny," Lisa said, a hint of amusement in her voice.

"He didn't do anything," Len snapped, "He's just an annoying little shit who rubs me the wrong way. He only came into this bar tonight to get under my skin."

Len took another sip of his drink, setting it back down on the bar a little harder than intended, causing some of it to spill out. He looked at Lisa to see she was smirking at him, her face not too far off from how Barry's had been when he looked at him.

"What?" Len snapped.

"It's working," Lisa shrugged.

"What?" he demanded.

"It's working," she repeated simply, "He's getting under your skin. I haven't seen you this worked up in a long time."

"I'm not worked up," Len gritted, glancing back at Barry again.

Barry wasn't looking at him now, but he had a small smile on his face as he sank his final ball, winning the game.

"I'm just waiting to see this kid get his ass kicked," Len said, smirking as he took a sip of his drink, watching to see how this would play out.

Tito looked like he was ready to kill the kid as Barry grabbed the stack of cash they had set on the edge of the pool table before starting their game. Barry walked away from the table without another word, cash in hand. Tito wasn't going to stand for it, though. He quickly made to follow Barry. It didn't work out too well for him, though, because after taking just a few steps, Tito suddenly face-planted it in the middle of the bar.

Someone had tied his shoe-laces together.

Barry didn't even look back as he walked away from Tito, who was now cursing and drunkenly struggling to untie his shoes. No. Barry was looking at Len, the smirk staying firmly planted on his face as he strolled up to the bar where Len was sitting.

"Hey, Snowflake," Barry greeted him, raising a hand up to signal the bartender, "You should take a picture. It'll last longer."

Len gaped at him for a moment. For the first time in his life, he was at lost for words. Len quickly rearranged his facial expression, giving Barry a blank look.

"I wasn't staring," he said flatly.

"Right," Barry smirked as the bartender set three shots of Jack on the bar, "That's why your face is as red as a lobster. Who's Scarlet now, Cold?"

Len gritted his teeth in anger, his hands curling into fists.

"What are you doing here, Barry?" he growled.

Barry held up a finger, signaling him to wait as he quickly threw back all three shots on the bar, one right after another.

"Thanks, Phil," Barry said to the bartender.

"No problem, Bar," Phil said as he walked away.

Len looked back and forth between the two of them, his face screwed up in confusion.

"How do you know Phil?" he demanded.

Barry shrugged.

"I'm just a social person," he said simply, "I like to meet new people."

Barry looked at Lisa then and raised an eyebrow, a small smile playing at the corners of his lips.

"Speaking of meeting new people," he smirked, "What's your name, cutie?"

Len's eyes widened. What the hell was Barry doing?! He knew exactly who she was and that she was Len's sister, even if the two of them had never officially met before. At least, not without the mask.

"Lisa Snart," his sister giggled, reaching out for a handshake.

Barry shook his head.

"Nah, I don't do handshakes," he chuckled, "I'm a hugger."

Len's breath hitched in his throat when Barry pulled his sister in for a big hug. The fucker winked at him over Lisa's shoulder! Len's grip on his glass tightened so hard, he thought the glass might break.

"You want to join me for a game of pool, Lisa?" Barry asked when they broke apart, "Just for fun. No bets or anything."

"I don't know," Lisa said, a playful smile working itself onto her face, "You just beat Tito in a game, and he's the best player in here. I'm not the greatest, myself."

"Nah, it's easy," Barry laughed, "It's all physics. I'll teach you."

Lisa's smile widened.

"Okay, then," she giggled.

Len stared at them as they walked over to the pool table. If he wasn't in shock he probably would have said something. He was too confused, though. What was Barry trying to do?! Did he want Len to knock his lights out?! Because that's where this was quickly heading. Seriously?! His sister?!

Coming into to his bar was one thing, but openly flirting with his sister right in front of him was another. Barry was asking for it.

Len gritted his teeth when he saw Barry lean over Lisa, teaching her how to shoot. He could see the satisfied smile on his sister's face as Barry leaned over her. She knew exactly what she was doing right now. She knew damn well how to play pool and certainly didn't need Barry Allen to teach her. Len hated both of them right now.

They were both doing this on purpose. Lisa was trying to punish him for coming out tonight, and Barry was—

Barry was touching his sister's ass!

Len saw red and nearly jumped out of his seat when he saw Barry's hand gently graze over his sister's ass as he was leaning over her.

He was going to kill him. He was going to kill Barry. Freeze him into a million tiny, little frozen Flash parts.

Barry knew how protective Len was over his sister. He knew laying a hand on her would be a death sentence. Still, Barry continued to lean over her, his hand running along her hip as he showed her how to line up a shot.

They would never find the body.

Len was just about to go over to them to break it up, but then Lisa giggled, and Len was reminded.

They were trying to get a rise out of him. Well, he wouldn't fall for it. Nope. Instead of going over to the pool table to slug Barry in the jaw, Len went to the men's room. He made his way over to the sink and splashed some water in his face.

"Calm down," he said to himself, "It's just Barry fucking Allen."

He didn't have to worry about Barry. Barry was a boy scout. He wouldn't actually make a move at Lisa. The kid was in love with that one reporter chick, and he was a hopeless romantic. Besides, Barry didn't have the balls to make a move with someone like Lisa. He could never handle her. She would eat him alive.

When Len exited the bathroom, resuming his cool, unaffected façade, he quickly saw how true that statement really was. Lisa was eating Barry alive. Or at least, Barry's face. Len stood there in shock as he watched Lisa sitting on top of the pool table, Barry pressing closer to her as they sucked face like they were the only two people in the room.

For a moment, all Len could do was just stand there in shock, watching Barry Allen make out with his sister.

And then any semblance of calm went out the window. Len hardly even registered crossing the room. One minute, he was standing outside the men's room, and the next, he was grabbing Barry by the collar and roughly ripping him away from his sister. Before Barry could even say anything, Len slammed his fist into Barry's face.

Len knew Barry could have dodged it easily, but he didn't for some reason. Instead, he took the hit. Barry still had a smile on his face as he spit out blood.

"Something wrong, Lenny?" he smirked.

"You're lucky I don't have my cold gun with me," Len growled lividly, "Or I'd turn your dick into a fucking popsicle right now, Allen."

"Lenny!" Lisa yelled, hopping down off the pool table to stand between them, "Back off! He didn't do anything wrong!"

"Seriously, Lisa?!" Len said incredulously to her, "Him?!"

"Yes, him," Lisa said calmly, "I'm a grown woman, Lenny, and I can go home with whoever I want."

"You—" Len sputtered, "You are not going home with him, Lisa!"

"Watch me," Lisa smirked.

She then grabbed Barry by the arm and strolled out of the bar with him. Len watched them leave with wide eyes, his mind short-circuiting as it tried to process what had just happened.

As soon as they were outside, Barry and Lisa finally let themselves burst into laughter.

"When do you think he's going to figure out it's April Fools Day?" Barry choked.

Lisa laughed and shook her head.

"How'd you even know he'd be here tonight?" she asked.

"Cisco," Barry answered with a shrug, "I didn't tell him why I wanted him to vibe your brother, though, or why I asked him to give me your number. He's probably just as confused as Lenny right now."

Lisa giggled and shook her head again.

"Well, it was definitely worth it," she choked, "I haven't seen Len that upset in years."

"Thank you for meeting me," Barry grinned, "You pulled that off beautifully."

"Oh, that kiss was very real, Barry," Lisa smirked, "Let me know if you ever want to mess with my brother again. I wouldn't mind taking things a little further next time, if you know what I mean."

Lisa winked at him before walking over to her motorcycle.

"See you around, Bar."

For the record, Cisco was dating Kendra at this point in the show, so Barry wasn't being a total asshole in this chapter. I've been dying to write a little GoldFlash scene since season one, even if it was sort of fake.
