"A-amina…" Nyssa stammered "What the hell are you doing here?!"

"To see you" Amina started

"Um, who is this?" Barry asked before realizing "Wait a minute, it's Nyssa's doppelganger. Why is she on our earth?!"

"Quite a simple explanation really" Amina started "Your earth's Nyssa set several bombs off at my concert. I'm here to get justice for those who died at your hand"

"I didn't bomb your concert" Nyssa replied

"Really? Because I seem to recall on the news that two strange vigilantes, besides the normal two, were spotted at the crime scene. I saw you there, and what you're wearing just confirms it"

"I was at the concert, but I did not bomb it. I have no reason to"

"I never said you did, but what can I expect from a power crazed meta?"

"Crazed meta?" Nyssa chuckled "There is too much you don't know"

"Then why don't you explain it to me?!"

"Because you don't need to know anything" Nyssa said while stepping forward "Go back to Earth 2 and focus on finding the actual attacker"

"Not until I get some answers on why you came to my earth in the first place!"

"She's just a stubborn as you were back when we first met" Oliver whispered

"It wasn't this bad" Nyssa groaned while pinching the bridge of her nose "You know what, Amina, come with me"

As Nyssa walked past Amina, she peeled off from the side and followed close behind. Is was visible to everyone in the room that their Nyssa was pissed beyond belief, so they just did their best to stay out of it.

"Mom seems more pissed off than she was when some rookie blew their cover in Algeria" William commented

"William! Language!" Oliver scolded, making William flinch a bit

"Sorry, but mad didn't really cut it"

"You're right there. A whole other word would be needed to describe what Mom's thinking" Oliver replied

-(=+=)-

Amina walked close behind Nyssa, hoping that she would be getting some answers as to why she was on Earth 2, what she was doing at the concert, and why the hell she was dressed up like an assassin with a freakishly large sword on her back. They were still walking when Amina realized where they were going; the breach room

"I'm just letting you know, I'm not going back to my earth until I'm given some answers" Amina stated confidently

"You might not go willingly, but you will go with the right amount of motivation" Nyssa said coldly without looking over at her

"Really? How so?"

"See that dagger on my right thigh"

"Yeah"

"It won't be in its sheath for long"

"Oh…um…you'd do that?"

"I have no problem doing what's necessary"

"Then I guess we're in the same boats. I want answers and you're the only one who can give them to me" Amina said "And I will not leave until I know why the hell you bombed my concert or why you were even there in the first place!"

"God you are so aggravating!" Nyssa said in a very annoyed voice "You want answers, fine. You have one minute to ask all the questions you want and then we're done"

"And you will answer truthfully"

"Yes, and that was your first question and eight seconds gone"

"Okay! Why did you come to the concert?"

"Curiosity"

"Did you bomb the concert?"

"No"

"Who did?"

"Ask the Green Arrow and his sidekick"

"How do you know Dr. Wells?"

"You're walking in another S.T.A.R labs. Figure it out"

"Why are you dressed like an assassin?"

"Because I'm an international assassin"

"Why?"

"Because I was trained to be"

"By your father, who was the man who wrote the note?"

"Yes"

"So what are you doing now?"

"Running a league of nine hundred other assassins, traveling around the world stopping threats, and acting as a mother as well as a husband"

"And your husband is…Tarren?"

"No. Oliver Queen"

"Wait, Oliver Queen?! The playboy from my earth?!"

"Your minute is long past gone"

"C'mon! You have to give me more than that!" Amina begged "One more minute!"

"Fine" Nyssa said after a moment of silence. She didn't want to admit it, but this was actually a bit fun for her hearing her doppelganger so desperate for answers.

"So how did you fall in love with a playboy?"

"He's not a playboy, that's who he was before he was stranded on an island in the North China Sea for over five years. I fell in love with a warrior after everything in my life was ripped away"

"I'm guessing you've been married a long time. That boy dressed in black and blue looked a little like Oliver"

"He's Oliver's child, but not mine"

"Wait, he cheated on you?!"

"He was in college at the time and I didn't know him. He thought the mother miscarried so he left it alone, but it turns out William was born and he was living a life in secret with his mother for around twelve years before Oliver found out. After his mother died, Oliver took him in and around a year later, I married Oliver and William became my son"

"That's quite a heartwarming story" Amina smiled

"My turn to ask the questions" Nyssa said with a small smirk "Your last name is supposed to be Raatko. Where did Amina come from?"

"Well my mother died when I was thirteen and I was left with my father. He's just a drunk comedian and I'm embarrassed to be related to him. When my career first took off, his reputation was stopping me from getting more record deals so I decided to cut off my ties with him. I legally got my last name changed to my mother's maiden name and I haven't seen him since!"

"Quite an interesting tale you have there" Nyssa started "Where did you get those two highlights?"

"Why, are they familiar?"

"Very"

"I see. They were just going to be temporary for a music video, but after they were in, I really liked them so I got my hair dyed this way permanently" Amina started "How are they familiar to you?"

"I was taken to the 'world' between ours and the afterlife. I met an old spirit who helped me form the league, then when I left the place, I had highlights exactly like those in my hair; however, they disappeared when the spirit's job was done"

"I have another question for you, and I think this is the last one" Amina started "Can you teach me how to defend myself? Like hand to hand combat?"

"I'm sorry, what? Why would you need to? You have an entire security team"

"That's the point. I have too many security members, it costs a lot of money and space, and if people really want to hurt me, I'd rather teach them a lesson myself rather than being seen as a coward"

"That is definitely something my doppelganger would say" Nyssa said with a slight smile "Why me?"

"Because then you won't get a bunch of publicity for training me, and it won't be able to spread all over the internet because we're on a different earth"

"Um, you're not staying here"

"Never planned on it. I'm just hoping that you can teach me a few things before I go back to my own earth"

"And you're going to drop this whole search for the attacker?"

"No, I'm going to talk to the cops and see how I can help. If you didn't bomb the concert, then that means the person who did is still on my earth"

"Wait, who helped you get here anyway?"

"Dr. Wells and his daughter, Jesse. She's a nice girl, and quite a brave one for going out as Jesse Quick every day to fight crime. It makes me really happy to meet fans like her"

"Meta fans you mean?"

"No, fans that devote themselves to something and persevere even when things seem impossible; but her being a meta makes it even cooler" Amina said "Say, do you want to not use a knife to get me through that breach and instead go get a coffee or something?"

"You want more answers, don't you?"

"There's a lot of explaining to do"

"Okay, fine" Nyssa replied "But we're not going out to get a coffee. It's almost ten o'clock at night and I'm not that desperate"

"Huh, guess you guys have different times than we do on Earth 2. When I jumped through, it was around eleven in the morning"

"This multiverse thing is weird" Nyssa muttered "Just follow me. I know a place"

"And where is this place?"

"Are you afraid of heights?"

"I don't think so, but I guess we'll find out"

"Good, because we're going up to the roof!"

"Is it a clear night?" Amina asked a bit excitedly

"I believe so"

"Yes! Perfect! Show the way!"

"Okay then, follow me"

-(=+=)-

"So what's the plan Arabesque? " Melody asked from where she was sitting on top of a crate

"We're sticking with the original. We've already completed phase one, and with great easy might I add" Arabesque smirked "Nyssa didn't see a thing"

"How was she supposed to?" Harmony asked "She was so occupied with her main dancers that she didn't even notice the backups slip out right before the show started!"

"C4 was quite a good idea. Great job coming up with that Melody" Arabesque said

"Not a problem. It's always a good distraction, as it causes so much chaos that isn't a bad show either" Melody smirked

"Hey Arabesque, I think you should run through this plan one more time, just to make sure we're all on the same page" Harmony said

"Very well" Arabesque replied "Now that Amina is distracted with the concert bombing, we now have about three to four days tops to find the stones here and get back to Earth 2. Once we have those stones, taking Central City out will be a breeze"

"How much are these stones supposed to boost our powers?" Melody asked

"More than any of us could imagine, which is why we need to get them and time is of the essence" Arabesque said before pulling out a phone she lifted from someone after getting out of S.T.A.R labs "Our map should be located at an old museum around eight miles from here"

"Great, then let's get going. Being on a different earth feels weird" Harmony said

-(=+=)-

"Hey Dad, have you seen Mom?" William asked when his dad walked into the room, where he and Cisco were playing blackjack

"Nope. I'm guessing she's trying to get her doppelganger home and out of trouble" Oliver replied "Why?"

"Just haven't seen her in a while. Cisco and I were going to have a poker battle and wanted to know if Mom wanted to join since she really likes playing"

"I bet she'll want to join" Oliver chuckled "I'll go find her"

"Thanks Dad!" William called as Oliver left the room

"William, man, that was a dumb move" Cisco said as he flashed his eyes up from his hand "Now we're both going to lose"

"But mom would split the pot with me so I've got nothing to worry about" William smirked

Oliver wandered around the hallways of the lab and checked all the normal places where Nyssa was, but didn't see her anywhere. Eventually, he wandered into the cortex where he saw Iris and Caitlin talking with each other

"Hey Iris, Caitlin, have you seen Nyssa?" Oliver asked

"Um, no. Not for the last two hours or so" Iris said "Are you looking for her?"

"Yeah. I've looked around in her normal spots and didn't see her there. Is it possible to check the security cameras so I can get a better idea of where to look?"

"Sure thing"

Caitlin got up from the table she was leaning up against and walked over to the computer station. She pulled up all the camera footage and did a quick sweep of what was displayed. Most of them were normal until she got to the one that showed the roof

"Hey Oliver, did you think to check the roof?" Caitlin asked

"The roof?"

"The roof" Caitlin repeated "She's up there and from the looks of it, her doppelganger is up there too"

"Okay, thanks Caitlin" Oliver said before walking out

Oliver walked down the hallway of the floor he was on and got into the elevator. He pressed the button labeled 'roof' and waited for a few moments. When the elevator let out a ding, the doors opened and Oliver saw he was in a small room of sorts. Right in front of him was a door that he assumed led outside. He pushed open the door and was immediately hit by the warm, late summer air. It was already dark outside and the stars could be seen from where he was at. Oliver stopped observing the scenery when he heard two identical voices up ahead

"So wait, here on your earth, Tarren's a trainer for the mayor's security detail in Star City?!" Amina said while holding back a laugh

"Yeah, and to make it more relatable to you, he has hit on me multiple times" Nyssa laughed "Each time got him a swift slap on the head with a bo staff"

"Well played indeed, but Tarren's not that big of an idiot on my earth" Anima started "He's actually one of the people that helps out with the financial part of being a pop singer"

"Definitely not the Tarren I know"

"Hey Nyssa" Oliver called as he started walking over "I thought you were going to kick Amina into the breach"

"I was, but we decided to get some questions answered before hand" Nyssa replied "And I actually don't regret it"

"Well thanks for that" Amina laughed "How come you guys have a whole squad of vigilantes, a league of assassins, time travelers, and an alien from another earth at your fingertips and I still struggle with finding backup dancers?"

"Uh, I think it's just pure luck with a bit of science" Oliver replied "Anyway, I came up here to ask if you if you'd be interested in joining William, Cisco, and I in a poker tournament, but if you want to stay up here, that's totally fine"

"You know how to play poker?" Nyssa asked

"I'm an average player. Maybe I could pick up some tips?" Amina asked

"Sure, but you should start by asking Oliver for some tips because mine can get kind of confusing" Nyssa warned

"That could be kind of fun" Oliver started, but was stopped when his phone started to vibrate in his pocket "Cancel the idea of playing poker. Barry and Cisco need us all down in the cortex. There's a break in at a museum and from the looks of it, you and I might need to step in"

"I've been dying to beat someone up" Nyssa smirked as she got up from the edge of the roof "You want to come Amina?"

"On the field, hell no. Watch from the cortex, I'd love to"

"Great! Let's go then!"

Amina and Nyssa both followed Oliver back into the elevator and eventually walked back into the cortex, where every crime fighter was dressed and ready to go, even Cisco who wasn't going out on the field

"Okay, glad to see you've all made it!" Cisco said "What's your doppelganger still doing here?"

"We were having a friendly chat on the roof" Nyssa said "So what's going on?"

"Break in at a museum. We were able to spot three females before the cameras cut out" Caitlin replied

"Okay then, Nyssa and I will join as back up"

"Cool, then I guess it's the four of us out there!" Barry said "The best members of Team Flash and Team Arrow, teaming up for an epic night out"

"Don't you start deeming yourself the best 'Mr. I used to where a stretchy sheet as a costume'" Cisco teased "Caitlin and I are obviously the best"

"Amen to that Vibe" Caitlin smirked as she gave her friend a fist bump "Here are your coms, now get out there before this problem escalates"

Oliver quickly put on his suit while Barry, Ralph, and Nyssa all got their coms ready. Amina stood off to the side with William and watched in fascination as the heroes got prepared for a fight. Maybe when her life as a pop star died down, she could pick up something as exciting as this.

-(=+=)-

Arabesque, Melody, and Harmony quietly but quickly made their way through the museum, looking for the map that would lead them to the stones that would boost their powers. They were all dressed in their attire that had marked them as 'The Sirens' just to keep the thread going.

"Alright, split up and find the map. You all know what it looks like" Arabesque whispered to her sisters

"I don't think you'll be splitting up to steal something anytime soon" A modulated voice said from behind the thieves "The only place you're going to is prison"

The three sisters turned around and saw some of this earth's famed heroes; the Flash, the Elongated Man, the Green Arrow, and the Phoenix.

The members of team Flarrow were met by the brown eyes of three, pale skinned, brown haired girls. They all looked pretty similar, so Oliver assumed they were all sisters. Each one of them had distinct differences about them. Arabesque, the leader, had read streaks in her brown hair and wore a black dress with a high low skirt. There were two parts of a red sash that crossed over her mid-section creating an X. In addition to her high low dress, she had on a pair of mid-calf black boots that paired with her dark red leggings. Melody had purple streaks in her hair while instead of having an X for her purple sash, she had in crossing from her left shoulder to the right side of her waist. She also wore black boots with dark purple leggings. Harmony had blue streaks in her hair, a blue sash that cross from her right shoulder to the left side of her waist. Like her sisters, she had dark blue leggings and black boots.

"See, we can't go to prison just yet" Melody teased "We haven't got what we came from"

"Guess you'll have to leave disappointed then" Ralph replied

"Everyone, turn on your body cams so we can see what's going on. These may not be ordinary thieves" Caitlin said over the coms

Subtly, all the members of the team moved to turn their cams on but one member wasn't as subtle as the rest. When Ralph moved to turn on his cam, Harmony spotted it and to everyone's surprise, except her sisters, she grabbed a knife from her sash and threw it into his upper arm. Ralph immediately reached for the knife as soon as it made contact with his skin while his teammates readied themselves for a fight

"What? Did you not think a thief would have knives on them?" Harmony teased

Before anyone could say anything, the three remaining members of Team Flarrow ran towards the sirens, not knowing that they were metas. Barry ran straight towards Melody, Oliver towards Harmony, and Nyssa towards Arabesque. All of them were surprised by the sisters' skills. While the members of team Flarrow threw attacks, they ducked, dodged, and threw their own attacks.

Amina, who was still in the cortex with Caitlin, Iris, Cisco, and William, was leaning over Caitlin's shoulder watching the fight from Oliver's body cam. While she watched his opponent, she felt a sinking feeling in her gut when a clear view of the person finally showed up

"No way…." Amina gasped

"What is it?" Cisco asked

"These thieves, I know them" Amina said

"How so? Are they from your earth?" Caitlin asked, a bit nervously

"Y-yeah…" Amina said "That's Arabesque, Melody, and Harmony. Three of my backup dancers"

"What are they doing here then?" Cisco asked

"I don't know…" Amina questioned "How did they even get to this earth?!"

"I'm not sure, but once we have them in a cell, we'll get some answers" Caitlin reassured

Nyssa ducked underneath on of Arabesque's hits, then weaved behind her and tried to kick her down, but she saw it coming. Arabesque grabbed Nyssa's leg before it could hit her and twisted it to the ground, making Nyssa stumble and fall. She quickly drew her knife from her thigh, got up, and started swinging at Arabesque. She did her best to dodge, but wasn't keeping the offensive for long. Eventually, she was able to confuse Nyssa for just a moment, then slip back.

"Sisters, I believe it's time we pick this fight up a bit!" Arabesque called

As soon as she said this, Melody and Harmony broke off from their fights and joined Arabesque a fair distance away from the members of team Flarrow. Nyssa, Oliver, and Barry all started to run towards them, but before they could, Arabesque started to sing. It was unlike anything any of them had heard before, and it was beautiful, almost luring. Melody and Harmony joined in with an accompaniment, making she song even more beautiful.

When the sirens could see their opponents had fallen under their spell, they quickly changed the pace of the song and made it more deadly. The three Flarrow members covered their ears from the sudden change and felt themselves weakening from the song.

"Gah…C-cisco…Caitlin…what's going on?!" Oliver said over the coms

"We're not sure, it's like the song of the sirens in old legends. It lures victims to their deaths!" Cisco replied frantically "Just try to resist!"

Arabesque saw that the song had done it's damage and motioned for her sisters to stop. Nyssa, being more experienced with recovering quickly in battle, quickly got up and ran towards the sirens. She lit one fist up with a bright fire and looked like she was about to throw it at the sisters

"Look here, it seems there are actually three metas instead of one" Arabesques smiled "Harmony, show her what you've got"

As Nyssa got closer, she made a motion to throw a flame towards the sirens but Harmony caught sight of it before. Harmony sung a quick note, made a fist with her right hand in front of her, and then shot it out to her right. With her voice, Harmony had created a sound wave that knocked Nyssa over to the right without any warning. Nyssa flew through the air and collided with the wall.

"Nyssa!" Oliver shouted as he got up from the ground, not even caring about stupid code names

"Oh look, we've done it now" Melody teased "Why don't we end this so we can move on with our task?"

Oliver and Barry both got up and started running towards the sirens. Ralph, who had regained control of his injured arm, also got up and joined his team mates. As they ran forward, all three sirens raised their right fists in the air and started to sing a short melody together. As they did, small signs of a sound wave formed around them.

Nyssa picked her head up from the ground and looked up to see the three sirens preparing what seemed to be a massive attack, and her team was running straight towards them. With all the reaming strength she had, Nyssa picked herself up, grabbed her sword off her back, and ran straight towards her team mates, hoping to intercept them. She tried calling out to them, but over the sound of the sirens' singing, she couldn't be heard.

Nyssa knew that they weren't going to stop and if they didn't they would probably end up getting themselves severely injured. Instead of calling out, Nyssa had to go to her last resort. Right before her team mates were a couple yards from the sirens, the sisters started to lower their fists and change the melody. Nyssa knew what was coming next, so she jumped out in between the sirens and her team mates, then did a round house kick in the air with her sword in hand. A large gust of wind was sent straight towards Oliver, Barry, and Ralph. It came too quickly and it knocked all of them back about forty five feet.

As soon as Nyssa had released the gust of wind, she was vulnerable to the sirens attack, but wasn't able to react before they released it. All three sirens leveled their fists in front of them and the sound wave they had been creating shot out and went straight towards Nyssa. It hit her straight on and she was forced to cover her ears. All she could hear was the sound of a disharmonious melody echoing in her head. The sirens kept on singing the deadly melody as the sound wave did it's work on Nyssa, causing it to seem never ending.

Oliver picked his head up after being flung back all those feet just in time to see Nyssa drop to one knee while holding her hands over her ears while the sirens sang the disharmonious melody. He tried to get up, but the remnants of the sound wave were taking their toll on him.

All Nyssa heard was this melody, the melody that seemed to get even more deadly by the second. Her memory started to get fuzzy and she couldn't remember what was going on, like she was slowly being sucked into a void. Before she had the opportunity to resist, everything around her changed before her memory was sent into darkness.

The sirens smirked when they saw the effects their singing had on the heroes. They held back when they saw Oliver get up and rush over to Nyssa, who was still on one knee looking down at the ground

"Nyssa! Hey, look at me" Oliver urged as he skidded to her side "Are you alright?! Look at me!"

Nyssa looked up at Oliver just slightly, but Oliver saw something that wasn't there before; a darkness in her eye, like that of a killer's. After seeing Oliver, Nyssa immediately jumped up from the ground and kicked Oliver down before picking up her sword

"N-Nyssa, what are you doing?!" Oliver questioned underneath her blade

"You seem surprised Oliver, like this isn't who I'm supposed to be" Nyssa smirked down at him

"If this is a joke, now really isn't the time!" Oliver said before the blade was moved closer to his neck

"You're right, a battle is never a joke"

At that moment, Oliver was able to see it. She wasn't going to back down for whatever reason. Oliver didn't waste any time in grabbing the side of Nyssa's blade, holding it in place, and rolling to his side to avoid its hit. Nyssa stumbled back and faced Oliver with the look of a killer. Oliver barely had enough time to react before Nyssa ran straight towards him and started to throw her punches. Oliver dodged and blocked as many as he could, but still felt the effects of some

"Nyssa! Stop! This isn't you!" Oliver urged while ducking underneath her leg, which she had swung towards his head

"Can't you see Oliver" Arabesque asked from the side "That's not your Nyssa"

"She's right Oliver" Caitlin said over the com "She's in some sort of trance, or hypnosis. It's an effect of the sound wave and the sirens' singing"

"What do I do to get her out of it!?"

"I'm not sure, but we're trying to figure something out!" Cisco said

"Arabesque, I got it" Melody said as she rejoined her sisters with a small chest in her arms

"Excellent" Arabesque muttered "I hate to break this up so quickly, it really has been a pleasure, but we must be going"

When Arabesque said this, Oliver got distracted for a moment. Big mistake on his part because Nyssa did a round house to his chest, knocking him down and back a few feet. When Oliver was down, Nyssa gave him one last glance and walked towards the sirens, who looked like they were welcoming her as a team mate, an equal.

Once Nyssa was with the sirens, they released one last sound wave, knocking the rest of the team members back. When Oliver and the rest of the team recovered, he looked around at his surroundings and saw that Nyssa and the sirens were nowhere in sight, like they had vanished completely.

"N-Nyssa…." Oliver muttered to himself, then turned to the rest of the team "We have to go after her!"

"No Oliver, we can't" Barry groaned as he got up while helping Ralph to stand "If we go at them again, we won't back it out alive, especially now that they have Nyssa at their side"

"But I can't just leave her! She needs help!" Oliver almost shouted

"She's in a trance! She doesn't know you as her husband, she knows you as her enemy!" Ralph said "She. Will. Kill. You…without mercy!"

"Oliver, they're both right" Cisco said "Come back to the lab and we'll figure something out"

"Don't worry Oliver, we'll get her back" Barry said after seeing Oliver's look of panic

-(=+=)-

"Well done sisters" Arabesque said as they walked into the warehouse they were staying in "And well done to our new team mate"

"Glad I could help some people with the same cause" Nyssa said with an evil smirk "After all, they don't stand a chance when we work together"

"And to that, you're right" Arabesque smirked "I trust that if we help you kill Oliver, then you will assist us in retrieving the stones?"

"That's the arrangement" Nyssa replied

"Why do you want to kill Oliver anyway?" Harmony asked, not knowing that the sound wave had done to their 'new team mate'

"Oliver killed my father. For that and several other crimes, he must die"

"And with all of us working together, we will all see justice done" Arabesque smirked "Until our next fight is upon us, what do you all say to some sparring?"

"Hmm, our favorite pass time" Melody smirked as she drew two knives from her sash "I'm in"

"Same over here" Harmony said while drawing her retractable blades from her bracer

"As am I" Nyssa smirked as she drew her sword "But let me teach you all a few things. After all, you did not grow up learning as an assassin"

"A new team mate and some lessons, how could this get any better" Harmony asked with a small bit of cheerful darkness in her tone
