"How many good guys are left? How many stayed that way?" - Ben Affleck, Batman V Superman: Dawn of Justice

In Russia, Talia al Ghul is having a cup of coffee at a cafe alone. Her quiet time was interrupted when a familiar-looking man sits down across her.

"Mr. Queen," greeted Talia formally.

"Talia," greeted Oliver.

"What brings you to Russia?" asked Talia.

"At the moment, you," answered Oliver. "There's a new player in Star City. She dresses like me, only in black, wears a mask, disguises her voice, and seems to be pretty good at shooting arrows. She's killing criminals without hesitation, but she's also protecting me."

"And what makes you think I have anything to do with this?" asked Talia.

"You gave me my first suit," reminded Oliver. "She wears the same design, except it's in black. Did you happen to train someone who may have connections to me?"

"As a matter of fact, I have," said Talia.

"Who was she?" asked Oliver.

"You sound like you know," said Talia, trying to read Oliver.

"What I know is that I want answers," said Oliver.

"I made her a promise to never reveal her identity to anyone," said Talia.

"If you're not going to tell me her name, at lest tell me her story," said Oliver.

"Are you sure you're ready to learn the truth?" asked Talia, wanting to make sure Oliver is asking the right question.

"I don't know what to think of her. My team is telling me that I should trust her, but I need a name and a face to know if I can trust her," said Oliver. "She's saved my life more than once. I owe her a lot, but I wanna be sure she has no vendetta that will endanger the people I love and my city."

"Be careful what wish for, Oliver. Sometimes, what you think you need isn't what you need," said Talia.

"Talia, answers, now," demanded Oliver.

"Just let me finish here, and then we'll talk somewhere private," said Talia, drinking her coffee.

Back in Central City, Killer Frost returns to the warehouse that she and her new team are using as a base of operations. They have already finished setting it up. They have computers, medical equipment, scientific instruments, and a gym for training. Caitlin walks in to see Black Siren practicing on a punching bag.

"Have fun in Star City?" started Black Siren.

"Plenty," replied Killer Frost. "Where are the others?"

"Park went to Big Belly Burger. Snart's robbing a jewelry store," answered Black Siren.

Black Siren stops practicing and takes off her boxing gloves.

"So, how'd it go with Prometheus?" asked Black Siren.

"A few cuts and bruises, but I managed to persuade him," answered Killer Frost. "All we need to do now is wait."

"Well, I'm getting tired of waiting," said Black Siren, wiping her sweat with a towel. "When does the fun begin?"

"Wait for the others. I don't want to explain the plan twice," said Killer Frost.

"But the goal is still the same, isn't it? Kill The Flash's loved ones before killing him?" asked Black Siren.

"I wanna burn his world to the ground before he meets his demise," said Killer Frost. "Death means nothing if you don't suffer first."

"I know you love to kill, but can you really bring yourself to kill him?" questioned Black Siren.

Killer Frost slowly turns around and looks at her comrade with her ice-cold eyes.

"You doubt me?" accused Killer Frost.

"You have hatred for him, yes, but there is also something else in the way you look at him," said Black Siren.

"And what pray tell do you think it is?" asked Killer Frost.

"Love," answered Black Siren. "You love him, don't you?"

The anger on Killer Frost's face when from subtle to obvious.

"I don't love him," denied Killer Frost. "He means nothing to me anymore."

"I think we both know that's not true," said Black Siren. "I told you about me and Oliver Queen. I loved him. I know the look on one's face when that someone has love and hatred for someone. I can see that look on your face."

"Even if I do, as you say, 'love' him, it doesn't matter," said Killer Frost. "After I take everything from him, I won't hesitate to put a shard of ice through his heart."

"And the fact that he won't give up trying to save you should make that easier," added Black Siren.

"He once said that we've been through too much together to let each other down," said Killer Frost. "He's a fool for allowing our history to cloud his judgment. Even if I kill everyone he loves, he will still try to save me. I'm not some common criminal or your typical every-day nemesis. I was his friend, and I'm gonna use that to win this war."

"But The Flash has an entire army of friends to back him up, ranging from here to Star City and throughout history," said Black Siren.

"Don't worry. I like to plan ahead," said Killer Frost, smiling.

Meanwhile, Iris was at the CCPN, digging up on the juiciest stories online. From her peripheral view, she saw Barry Allen coming her way.

"Hey," greeted Iris.

"Hey," greeted Barry.

"What are you doing here?" asked Iris.

"I, uh, thought it was time for us to patch things up," said Barry. "Dinner tonight?"

Iris smiled. "That's sweet, Barry, but..." Iris' smile dropped as she paused. "... I don't think I can do this anymore."

"What do you mean?" asked Iris.

"I was on my way to Cisco's. I heard you and Kara," said Iris.

"Oh, you heard all that," said Barry awkwardly. "Look, Iris, all of that... i-i-it doesn't mean anything. Kara likes me, but I don't feel the same way about her. Besides, you heard what she said. She was wishing me luck that we patch things up."

Iris ' mouth gaped open for a few seconds. "I must've walked out before hearing that."

"I don't love Kara. I love you," said Barry.

"I know that, Barry," said Iris. "But what I did was unforgivable. I... I don't know if I want to try anymore."

"Are you saying we're over?" asked Barry. "Iris, Kara will be going back to her Earth after all this. She has friends and family to return to. Nothing can happen between us even if we wanted. Iris, you're the only one for me and I don't want to lose you."

"But I feel like I'm losing you," said Iris.

Barry didn't say a word, shocked by what he's hearing. He finally wanted to patch things up with Iris, but she's pushing him away.

"Iris, don't do this," pleaded Barry, shaking his head.

"I don't want to it, but I don't know what to do," said Iris. "Barry, I love you. I always will. But right now, things are way too complicated. Kara loves you. Maybe you don't love her, but..."

"Iris," muttered Barry. "I will never leave you for anyone."

"I wanna take this chance, Barry, I really do, but..." Iris paused. "Maybe another time."

Iris returns to her work, leaving Barry unable to say a word. He turns around and leaves the building.

Back in the warehouse, Doctor Light and Golden Glider returned. Lisa had a new bracelet on her wrist.

"Nice charms," complimented Black Siren.

"I just thought of snagging one for myself," said Golden Glider, showing off her new accessory.

"Alright, ladies, front and center," ordered Killer Frost.

Laurel sat on an oil drum. Lisa leans towards a pile of crates. Linda stood just a few feet away from Caitlin.

"As I've already told you, I want more than just to kill The Flash. I want to turn the city he loves into a wasteland, and today, we get started," started Caitlin. "First off, I was thinking of a good ol' fashioned bombing."

"Where?" asked Linda.

"Interesting question, Linda," replied Caitlin. "We're not just gonna bomb one place. We're gonna bomb four places at once."

"But what will this accomplish?" asked Laurel.

"You know I like to play games with my old friends," reminded Caitlin. "The bombing will just kill people, but that's not the goal."

"Don't you think you've played your friends too much that it's gotten to the point they will know you have a secret plan behind the bombings?" questioned Lisa.

Caitlin smirked. "I'm counting on it."

"So you have a plan behind a plan behind a plan," guessed Lisa.

Caitlin continues. "We'll plant the bombs in four strategic locations. We keep them guessing, while we execute the plan."

"And you're not telling us?" questioned Linda.

"I think if I really want to keep my secret plan a secret, it's best I keep it to myself, in the event one of you is captured and questioned," said Caitlin.

"None of us are gonna get captured," said Laurel confidently. "But smart."

"Well, girls, let's get out there and create some chaos," ordered Caitlin.

After the sun has set, four bombs were detonated almost simultaneously. The first bomb went off at the CCPD. The second one went off at the Gold City Bank. The third one went off at Central City Train Station. The fourth went off at Rathaway Industries. Firemen and what's left of the authorities arrived at each scene. The Flash arrives at the police department. Kid Flash oversees the damage at the bank. Jesse Quick volunteers to check the train station. Since Sara and Leonard have recently been called back to the Waverider, Cisco volunteers to check on Rathaway Industries with Joe and Patty.

Meanwhile, Killer Frost and her team arrive at Mercury Labs' secondary building. As soon as they walked through the front door, they are met with dozens of guards with guns trained at them.

"I see Dr. McGee has upgraded security," mentioned Killer Frost.

"How many?" asked Doctor Light.

"By my count, 24," said Golden Glider.

Black Siren tells Caitlin, "I told you we should've went for a quiet break-in."

"But where would the fun in that be?" replied Killer Frost. "Besides, I need my nightly murders."

"Does that explain the random killings the past few weeks?" asked Doctor Light.

"My codename starts with 'killer,'" reminded Killer Frost. "Besides, a good kill relaxes me."

"You're sick. I admire that," said Black Siren, admiring Killer Frost's bloodlust.

"Put your hands up or we will shoot!" ordered a guard.

"Do as the men say, ladies," said Killer Frost.

Caitlin and her comrades raised their arms. Four guards approached them to cuff them. Caitlin gives Linda a look. Linda nods. Before a guard can cuff her, Linda unleashes a burst of light. Caitlin, Laurel, and Lisa shielded their eyes. All the guards are temporarily blinded. Caitlin impales a guard with an icicle. Laurel kills one guard by snapping his neck. Lisa takes out three guards with her Gold Gun. Linda simply fired an energy beam at the guard close to her.

"I'm disappointed, Park," said Killer Frost.

"Not now," said Doctor Light.

"Let's just kill all of these red shirts and get to the lab on the top floor," said Killer Frost.

Before the four can advance, someone comes crashing in. It was Supergirl.

"The Flash figured you'd pull a fast one on him, so I volunteered to patrol the entire city," said Supergirl.

Golden Glider fires her gold gun at Supergirl, encasing her in gold. Lisa smiles at herself, until Supergirl breaks out of the gold with ease.

"She's powerful. Your gun won't do anything," said Killer Frost.

"So, what's the plan?" asked Golden Glider.

"Fight," said Killer Frost.

Killer Frost, Black Siren, and Doctor Light rushed towards Supergirl.

"So, the plan is no plan. I like it," said Golden Glider, joining her teammates.

Supergirl easily knocks all of her enemies down by flying at super speed and punching them.

"This is too easy," bragged Supergirl.

"Don't get cocky, kid," said Killer Frost.

"You're Caitlin, right? Barry's old friend?" asked Supergirl. "All those times you played us tell me you're a smart girl. I assume the bombings were your work. Pretty smart, but not that smart. If you've done your homework on me, you know I'm not easy to take down."

Killer Frost gets up and takes out a green shard. "That's why I brought this."

Caitlin walks closer towards Supergirl. The green rock was clearly weakening the Kryptonian.

"Doesn't take much, does it?" started Killer Frost. She looks back at her comrades and tells them, "Find McGee. I'll take care of things from here."

Laurel, Linda, and Lisa knock out some guards as they made their way to the elevator. Caitlin, meanwhile, was still pointing the Kryptonite at Supergirl. One guard regains enough of his vision to get a clear shot of Caitlin. However, Caitlin saw him aim his gun at her, and kills him by firing an icicle through his heart.

"How can you and Barry be friends once? You're a monster," said Supergirl.

"I wasn't always a monster," said Killer Frost. "I was once a scientist, a bio-engineer. I used my experience in bio-chemistry and computer science to help make the world a better place. I wanted to learn more, discover, and heal people. Unfortunately, The Flash was born and I became this... monstrosity."

"I know what he did to you, but you can't blame him," said Supergirl.

"I don't blame him. I just can't forgive him," said Killer Frost. "I told him that I would make him suffer by killing everyone he holds dear. Unfortunately for you, my friend..." Caitlin thrusts the shard of Kryptonite into Supergirl. "... you're one of them."

Supergirl collapses to the floor while Killer Frost heads to the elevator. A few guards get in her way, so she fights them hand-to-hand. In the end, every guard in her way get either a broken arm, an icicle through the heart, or a broken neck. After all the bloodshed, Killer Frost takes a moment to enjoy the feeling. She heads for the elevator.

Flash arrives and pulls the Kryptonite shard from Supergirl's body. Kara shouted when he did, but she was still weak. Flash looks at the elevator. Caitlin smirked and waves just as the doors shut.

"Supergirl, are you okay?" asked Flash.

"That may have to wait," said Supergirl. "Get her."

Flash races up the stairs and stands by the elevator. The doors open and saw Caitlin Snow standing next to a dead body.

"He was on his way for a job interview with Dr. McGee. Told him to 'break a neck,'" joked Killer Frost, giggling.

"We're done playing games, Caitlin," said Flash. "You're gonna come with me and I'm gonna help you."

"All this death and you still think I'm worth saving. You're pathetic," replied Killer Frost.

In the laboratory, Dr. McGee was being guarded by three guards. The door is broken off its hinges by a sonic cry, courtesy of Black Siren. Everyone in the room had to cover their ears.

"Nice to know you have a knack for the theatrics," said Lisa.

"I like to make an entrance," replied Laurel.

"What do you people want?" asked McGee.

"The new power source," answered Linda. She aims her hand at one guard. "Give it to us or this man dies."

"Ooo, I like this new fire in you," said Laurel, impressed by Linda's will to kill.

...

McGee led the three ladies to the basement labs via an escape elevator in her office. Linda took one guard just in case.

"Mr. Allen will stop you," said McGee.

"He will surely try," replied Laurel. "Keep moving!"

McGee led Black Siren to Vault TF-125. She opens it with her hand print. The safe opens. Inside it was a device.

"The power source is inside," said McGee.

Black Siren punches through the circuits and pulls out the power source, in the form of a hand-sized glowing cylinder.

"You have you want. Now let that innocent man go," said McGee.

Laurel looks at Linda. She gives her a nod. Linda fires an energy blast through the guard's heart.

"Look at that. Your first on-purpose kill," said Lisa, feeling proud. "How does it feel?"

"I'm still working on the 'no remorse' part," replied Linda.

"Close enough," said Laurel.

"If you're gonna give me another lecture, Flash, I'm not really interested," said Killer Frost. "Nothing you say will matter to me in the slightest."

"That's why I'm not gonna talk to you," said Flash. "As much as I hate to do it, I'm locking you in the pipeline."

"You don't want to do that," said Killer Frost.

"Why not?" asked Flash.

"Look behind you," said Killer Frost, looking over Barry's shoulder.

"I'm not falling for that," said Flash.

"Mr. Allen!"

Flash turns around and saw Dr. McGee. Lisa Snart's Gold Gun was pointed at her face.

"Let her go," insisted Flash.

"Take another step closer and she's solid gold," threatened Golden Glider.

Black Siren shows Killer Frost the power source.

"Good work, girls," said Killer Frost. "Not exactly how I wanted this night to go, but I'll take it."

All of a sudden, Supergirl smashes through the floor and tackles Lisa Snart to a wall, causing her to drop the gun. Laurel quickly grabs McGee and puts her hand on her head, preparing to twist it in case of an attack.

"Now, let us go or the pretty lady here loses her neck," threatened Laurel.

"Kara, let them go," said Flash.

"Are you nuts?" questioned Supergirl.

"We'll take Lisa with us, but the rest go free," said Flash.

"You're not just gonna let them take me, are you?" Lisa asked Caitlin.

"Don't worry, Golden Glider. We'll come for you. Eventually," said Killer Frost.

"Caitlin," called Flash. "Just tell me. Do you really want this? Is a world of chaos and crime really what you want?"

"Killing you is my top priority, Flash, but I have to make room for other plans," said Killer Frost. "Central City will be ashes. Star City will be, too. The world will crumble after you do. I promise you that."

Killer Frost, Black Siren, and Doctor Light leave the building with Dr. McGee as a hostage, at least, until they were outside. They left McGee on the street with a freezing forearm, courtesy of Killer Frost.

Back at the warehouse...

"Are you sure you want to get Snart back?" asked Black Siren.

"Well, not now," said Killer Frost. "We can't just barge into S.T.A.R. Labs. Knowing Cisco, he's probably upgraded the security."

"That gun of hers is the only reason she's on this group of ours. Why not just break in and take the gun?" questioned Black Siren.

"Because Golden Glider is more than just an asset on this crusade," said Killer Frost. "She's valuable because of her history as a criminal. Plus, anyone with a will to kill is on my good side."

"Well, we got the power source," said Doctor Light. "Although, I didn't expect to see Flash and Supergirl to crash the party."

"I did tell you that I had a secret plan, right?" reminded Killer Frost.

Killer Frost heads to the computer and contacts Jesse James.

"Jesse, is the package delivered?" asked Killer Frost.

"You betcha, Frosty," replied Trickster. "I left it exactly where you asked me to leave it. I think you'd also like to know that Axel and I dropped three bodies just to get this little baby."

"Well, as always, I appreciate your services," said Killer Frost.

"Our raid at Mercury Labs was just a ruse," realized Doctor Light.

"Not entirely. We really did need the power source," said Killer Frost.

"Remind me again why Jesse isn't part of our crusade anymore," asked Black Siren.

"He's crazy," said Killer Frost.

Black Siren nods, agreeing.

"He's still an ally, but no longer a member of this team," said Killer Frost.

"What 'package' did you ask him to bring?" asked Doctor Light.

"I'm afraid that's still a secret," said Killer Frost. "But don't worry. When the time comes, I'll let you in on it."

"I see Supergirl is still alive," pointed out Black Siren. "I thought that green stuff is supposed to kill her."

"Flash arrived too early," said Killer Frost. "But I still have plenty more where that stuff comes from. Supergirl will be dead soon enough."

"What about Oliver Queen?" asked Black Siren.

"Oh, we'll worry about the Green Arrow another time," said Killer Frost. "Besides, he has an old friend and a baddie in green who both have scores to settle with him."

"Why not just kill him?" asked Black Siren.

"It's not enough to simply kill your enemies, Lance," said Killer Frost. "Making them suffer first makes their deaths all the more satisfying. But keep in mind. Oliver Queen isn't The Flash's only friend. He has plenty, and I can't wait to drain the life out of them with my very own hands."

"If I wasn't a criminal, I'd be pretty terrified of you," replied Black Siren.

"So, what now?" asked Doctor Light.

"How about a few drinks?" suggested Killer Frost.

"I love the sound of that," said Black Siren.

Not my best work, but I still hope this was fun enough. Leave a review and let me know what you think.

As for the next chapter, we'll be focusing heavily on Star City. I'm making a twist to Arrow, Episode 5x10.
