Alright. Back with another chapter.

We are finally getting into the exciting part of this story. The culmination of the war with Prometheus. And in this chapter, we'll get to a showdown I'm sure you're excited for.

Let's get to it.

Chapter 18- Siren on the Hunt

Bucky slowly walks along the road in downtown Star City, hands in his pockets. It's been two days since the incident. Since then, there have been tensions in the bunker between Felicity and the rest of the team. Particularly Diggle, as he was familiar with Helix due to his connection to ARGUS.

Since then, Bucky hasn't spent much time in the bunker, or even operating as the Winter Soldier. He has just needed some time to himself. He's spent the last two days either by himself or with Laurel. She is the only one who he feels he can truly be himself around.

As Bucky walks around a corner, he gets a craving for an ice cream. Knowing there's a Dairy Queen not too far away, he turns in that direction.

Suddenly, he hears a whistling and he just manages to duck aside. He whips around, and sees Prometheus stalking towards him.

Bucky growls and runs right at Prometheus. Prometheus rushes at him, and the two clash with a flurry of punches and kicks.

Bucky successfully blocks Prometheus' blows for several moments. Then, Prometheus gets in a kick to his chest, knocking him back several feet. Bucky stumbles to a stop, and readies himself to keep fighting. Then, a loud scream splits the air, and a shock wave knocks him flying back.

Bucky gets knocked tumbling. He scrambles to his feet, trying to turn to face Prometheus. But, as he does, he sees Prometheus with his bow aimed and an arrow nocked. Before Bucky can react, an arrow drives into Bucky's right shoulder. A second one hits him in the lower stomach. Bucky stumbles, then collapses to the ground. Prometheus chuckles before turning to and walking away.

Only moments later, Captain Pike comes around the corner, on the way to get an ice cream himself. He sees Bucky lying on the ground, two arrows sticking out of him, and races over. "Captain Pike to Central! We have another Prometheus attack! One victim down! I need an ambulance at 8th and State!" he says loudly as he races up Bucky.

(Hours later)

Laurel wrings her hands nervously. She, Diggle, and Rene have all been waiting in the lobby of Starling General for several hours now. Quentin joined them about an hour ago.

"Party for James Buchanan Barnes?" they hear someone call out. All four of them turn towards the sound of the voice, and see a doctor with a clipboard standing outside one of the sets of doors leading further into the hospital.

All four of them stand up and walk over to him. "How is he?" Laurel asks with worry.

"He's gonna be okay. The arrows didn't damage any vital organs. And his blood loss wasn't too bad. He'll need a few days in recovery before we can release him. But, he'll live," the doctor says.

"Can we see him?" Diggle asks.

"Yeah," the doctor says as he leads them through the doors and down the hallway. They go up a few floors and down another hallway, and the doctor stops in front of a door. "He's in here. I'll let you all talk alone," the doctor says.

Laurel rushes in, the other three following her. In the center of the room, they see Bucky lying on his bed, wide awake. He looks over them and smiles. "Hey, guys. What's up?"

"What happened?!" Laurel bursts out.

"I was out for a walk. Prometheus tracked me and attacked me when I was in a less crowded area. I was fighting him, when I had a scream and got knocked over. I'm guessing that lady with a Canary Cry that we spotted with Viper came with him. After her attack, it gave Prometheus a chance to shoot me," Bucky says.

Laurel's face grows angry. Diggle, in the meantime, asks, "What do you think he was trying to do? I doubt this is just a random attack. Do you think he could be trying to distract us from something else? Or take out the biggest threat to his next step?"

"I don't know," Bucky responds.

Laurel, however stand there in silence, thinking about Diggle's questions, wondering what Prometheus was hoping to accomplish by attacking Bucky. And wondering why he didn't just kill Bucky.

"Laurel?" Diggle asks. She looks up and sees everyone is looking at her.

"I'm sorry. I need to use the restroom. I'll be back," Laurel says. She smiles reassuringly at Bucky then turns and walks out of the room. As soon as she gets out of the room, her face goes deadly serious, and she clenches her fists as she heads back the way they came in.

(The bunker)

Laurel strides into the bunker. Felicity and Curtis are talking at the computer station, and turn to look at her, and are instantly concerned by the look on her face.

"What's wrong? Is Bucky okay?" Felicity asks in concern.

"He'll be fine. He'll be better once I find Prometheus," she growls.

Felicity and Curtis both look alarmed. "You can't go after Prometheus alone, Laurel. He's got too many allies!" Curtis protests.

"He attacked and nearly killed someone I care about. He's gonna pay for everything he's done. And I'm going after him, whether you like it or not. And you can't stop me. So, what's it gonna be?" Laurel responds fiercely.

Felicity and Curtis both stare at her for a moment. Finally, Curtis holds up his hands in surrender and says, "Alright. We'll help."

Laurel nods, then stalks over to them. "Bucky said that it wasn't just Prometheus who attacked him. The lady who has a scream like mine was with him. And I think that she's gonna be easier to track. Find her," she orders.

Felicity quickly turns and begins typing. Laurel turns and heads towards her uniform. "I'll head to the site of the attack. Call me when you have a location," she says.

(Attack site)

Laurel bends down, examining the footprints in the gravel. She looks up, following the footprints. Knowing where Prometheus had to be, these footprints had to be that woman who was with Prometheus.

"Laurel?" Laurel's head jerks up at the sound of Felicity's voice over her comms.

"What do you have for me, Felicity?" she asks.

"I've spotted that woman. She's just three blocks north of the old lair, and heading towards it. If you head right for Verdant, you should be able to intercept her," Felicity says.

"On my way," Laurel responds. She races to her motorcycle, hops on, and takes off for Verdant.

It doesn't take too long for her to reach Verdant. She parks her motorcycle just around the corner from it, then climbs up a fire escape to get on top of a neighboring building.

She slowly makes her way to the north edge of the building, leaning over the edge and watching the street below her. It only takes a minute before she sees a woman wearing a black leather coat walking along the sidewalk.

"Gotcha," Laurel whispers. She jumps off the roof and onto the fire escape. She races down it, and at the bottom she leaps off of it and onto the sidewalk. She slowly stands and looks right at her opponent. And with a shock, she recognizes her.

"Dinah Drake," she says in a low voice, remembering meeting her doppelganger during her time going to law school.

"You know me?" Dinah asks.

"I met you a long time ago. You wouldn't remember me. But it doesn't matter. I'm gonna take you down," Laurel says. She leans forward and unleashes her scream. Dinah dodges to the side, avoiding it. She pops up and unleashes her own scream. Laurel doesn't dodge fast enough, and gets knocked back.

She scrambles back to her feet, only for a second cry to knock her down. Again, she tries to scramble back to her feet. As she does, she sees Dinah right in front of her. However, Dinah quickly lands a punch right to the face, again knocking Laurel down.

"We may have the same power. But I think I'm better than you. And once I beat you, I'll help Prometheus defeat the Winter Soldier. And then, the Green Arrow will finally show his face," Dinah says.

Suddenly, there's a strange whirring noise, and something smacks Dinah really hard and knocks her over. She tries to shake it off, and both her and Laurel turn to look down the street, where they see Curtis, dressed in his uniform, and T-Sphere in hand.

"You know, I think you really ought to shut up," Curtis says before running right at Dinah. She shifts into a better stance, and throws a punch as Curtis reaches her.

For several moments, the two exchange blows. Then, Dinah gets in a shot right at Curtis' leg, then knocks him back. Before she can get in another blow, Laurel, no longer dazed, lets out a cry, knocking Dinah flying back.

Laurel stalks towards Dinah. But, before she can unleash another cry, Dinah throws something down. A moment later, it explodes in a cloud of smoke and light, forcing them to avert their gaze. When they turn back, DInah is gone.

Laurel looks at the spot where Dinah was, growling at her missed chance. Then, she turns to Curtis and says, "Thanks for the assist."

"No problem. Now, we just have to try and figure out who the h*** this woman is," Curtis says.

"I already know who she is," Laurel responds.

(The bunker)

"Her name is Dinah Drake. Back on Earth-2, I met her during my time in law school in Central City. She was going into the police academy, but flunked out. Next I heard of her was on the list of names of casualties caused the particle accelerator explosion on Earth-2," Laurel says to the whole crew, who has all gathered after Felicity issued the call.

"And on this Earth, she instead survived the explosion and got the same powers you did," Diggle remarks.

"Yeah. But, her cry seems more focused than mine. And, she seems very competent at hand-to-hand," Laurel says.

"She beat me without hardly a problem. If you don't count her advantage with her cry, I don't think me and Rene can beat her. And maybe not even you Laurel. Only Diggle and Bucky I think really have a chance," Curtis adds.

"Well, it's not a surprise she's so good. I just looked her up. She used to be on the Central City police department. She was one of their finest. She was on an undercover mission right before the accelerator explosion, investigating crime lord Sean Sonus. Her partner, Vincent Sobel, was killed by Sonus. She quit the force shortly after his funeral. And, I found out that Sonus was found dead on a building roof in Hub City, along with a large number of his men. Evidence shows that Prometheus was involved. If I had to wager, I'd say that Prometheus tracked down Miss Drake, helped her get revenge on Sonus, and then got her to help him as repayment," Felicity says.

Laurel sighs. "So, Prometheus not only has Evelyn Sharp and Viper helping him, but also a woman just like me, Carrie Cutter, China White, and Digger Harkness," she mutters, realizing just how many allies Prometheus has.

"We need to be on full alert. I got something out of Dinah. From what she said, I think that Chase still thinks Oliver is here on this Earth. He thinks that Bucky is protecting him. Taking his place to try and take down Chase and keep Oliver out of harm's way. He thinks Bucky is something like Oliver's hired muscle to deal with Chase. Dinah said once she took me down, she'd help Chase kill Bucky for good, and then they'd be able to draw Oliver back out," Laurel says.

"Well, that's not good," Curtis says.

Diggle starts to smile. "No, that may actually be good news. Chase doesn't know yet that Oliver is on another Earth. Maybe we can use that fact against him," he says.

"How?" Laurel asks.

"I've got an idea. But I need to make a call," Diggle says. He walks off, pulling out his phone.

Suddenly, there's a beeping from the computer. Felicity turns towards it, and types a few keys. She suddenly freezes, then throws her arms up and says, "Yes!"

"What is it?" Rene asks.

"HELIX came through! They just sent me this! They got it off footage from a satellite," Felicity says as she hits the play button. Everyone watches as Prometheus turns away from something, facing in the direction of the camera, and pulls off his mask, revealing the face of Adrian Chase.

Laurel breaks out in a huge grin. "Yes! We've got him!" she says.

Rene and Curtis both start grinning. After another moment, Laurel says, "I'll take this to my dad. He'll get it to the SCPD."

"And I'll throw this up on Youtube. There won't be anywhere the SOB can run," Felicity says triumphantly.

Laurel smiles as Felicity hands her a USB. Laurel beams as she heads for the exit.

(SCPD Precinct)

Quentin smiles as the video footage comes up. He couldn't believe it when Laurel walked into his office with that footage.

"Now, we have run this footager by three different experts. It has been authenticated. It has not been altered in any way. That is raw footage you're seeing," Quentin says as the video clearly shows Chase removing his mask.

"Chase is over at City Hall right now," one of the female officers says.

"Well, call the ACU and have them place the SOB under arrest," Quentin says. He looks around, smiling a bit at the triumphant smiles on many of the officers' faces.

(City Hall)

Chase scribbles away, finishing a memo for a court case, while silently wondering how Dinah did on her mission of drawing out Black Siren.

"Mr. Chase," a voice calls from outside his office.

Chase looks up. Even though it sounds harmless, he grabs his pen, and a small knife. "Yes?" he calls back.

A moment later, the door is smashed open as four ACU officer race in, weapons raised. Chase reacts instantly. He throws his pen into the eye of one of them, and the man collapses in agony. Chase then flips his desk and shoves it towards them. They try to jump aside, but Chase leaps over the desk. Grabbing one by the throat, he stabs him through the ear. Another officer tries to hit him with his gun, but Chase gets under his guard and slits his throat. The last officer tries to shoot him, but Chase uses the guard he just killed as a shield, then throws him at the standing officer, forcing the officer to stumble. Chase throws the knife, which goes right through his throat.

Chase stands amidst the bodies. He soon reaches down and picks up a pistol before pulling his knife out of the officer's throat. He then races towards the window and leaps out, disappearing into the night.

And, I'll end there.

I hoped you liked the showdown between Laurel and Dinah. I also promise that this will not be the last time they fight. They will face each other at least one more time.

Obviously, Laurel knowing Dinah's doppelganger is something of my own invention. I just put it in there so they would be able to find out her identity.

I originally had another plan for this chapter. I had a thought of introducing another villain on Chase's side to rescue him from the ACU, with Marvel's Count Nefaria being the prime candidate, but I decided he had enough allies. The reason for almost introducing Nefaria will be explained after the last battle.

Next chapter will feature Chase's capture, and you'll find out Diggle's plan. It may surprise you all. Also, please let me know if I should still have Chase kidnap William as an extra hostage.

Until next time, please, please review and give me your feedback. And stay tuned!
