Hope u guys like it!

Chapter Summary: Evil Kara under the influence of red kryptonite and Oliver gets on a mission together when Oliver has to go back to his old days and Kara helps him.

Kara floated high on the space, looking to planet Earth below her. Her heart ached, she felt miserable, way more than she ever felt before and there was nothing she could do to change that. She floated there, thoughtful about everything that just happened, and it broke her heart.

Her best friend, Lena Luthor, hated her. She found out Kara Danvers and Supergirl were the same person and felt betrayed, so much she cut all ties she had with Kara or Alex, and fired her from CatCo. She still remembered her harsh words.

FLASHBACK

- I guess I can finally understand my brother and his hatred for Superman. You aliens think you are above us; you don't actually trust us you just use us for whatever you need. While we believe we have real friends to count on, you lie behind our backs! I was never your friend, was I? I was just someone you could use, you could make a fool of, but you never really considered me as your friend. You fooled me Kara; you made me feel like a fool. I see what my mother sees now. I can't blame her for being the way she is. It's just a matter of time before you get sick of us and turn your back on humanity, how can I be sure it won't happen? How can I trust you, if you never really trusted me?"

END OF FLASHBACK

Lena's words echoed through Kara's ears every day since that awful conversation happened.

And right after it, there was her battle with Reign. One more thing that made Kara feel awful and hurt like never before.

Reign killed her dear friend, James, which made Lena way more pissed, hurt and angry than she was before with Kara. She blamed her for not doing what was necessary to help James. Alex was also mad at her. Alex told her Reign wasn't going to have mercy on them and Kara believed she could still reach her. It was Sam for Rao's sake, their friend. Alex saw no hope for her, but Kara insisted she wasn't going to kill her. Alex begged her to, and Reign ended up killing James. Winn was so sad he vanished and no one could find him. Alex and J'onn joined forces and managed to take her down, after Alex almost got killed as well. Their fight was so awful, Kara couldn't take it and flew away and now she was in space, floating and thinking about all the awful things that happened.

She remembered how it was when she was under the red kryptonite influence. She did awful things, sure, but she never felt so free, so ok with herself. She felt way stronger now and more understanding of her powers, so she was sure she could handle it in a better way. She felt desperately in need for an escape. And them, she got an idea.

She flew back to her apartment in super speed and went directly to the drawer in her bedroom. She picked up a small box and opened it. There was it, a ring of red kryptonite someone left at her door once and she decided to hide it, just in case. She looked again at her drawer and picked up her extrapolator, smiling to herself as she put the ring on and opened a breach.

She needed some time off, some freedom. And she was going to get it!

Oliver hated those kinds of parties, but at least it was not in a boring place. Thea managed to reopen Verdant, but in another part of the city. She decided it was going to be a different nightclub, more sophisticated and Oliver gave her all his support. He had to be there as the city's Mayor, dealing with annoying people who wondered why he was supporting a nightclub again when the last time he tried, it failed big time. He went to the bar to get a drink, thinking it would help him clear his head. So much had happened lately, he felt angry all the time, feeling the need to punch someone, anyone, but having to hold back because he was the Mayor of the city and it would look bad. As the Green Arrow he was having a hard time doing it, because Cayden James was making his life a living hell, he felt like losing all the time he went after him, half his team were still disbanded, Diggle still felt his arm pinching and there was Felicity. They broke for a while after she said a big no to his proposal, but decided to stay and help the team because they were shorthanded. The vibe on the bunker was never so weird and it annoyed him her mean comments every time she got a chance to do it. He just decided to ignore it and keep living his life with his son. Thank God at least William understood more about what he did, and was more supportive. It was one less stress in his life.

He was drinking scotch and he felt a hand on his shoulders and turned around, looking surprised at the person standing before him.

- Kara?

- The one and only! – She smiled to him in such a way that made him feel hypnotizes for a second.

Oliver took a look at her, still feeling surprised to see her there. He noticed something was different about her, and not just her clothes. She stood there, smiling confident, wearing a super tight black pants with a thin silver belt on her waist, a dark green tank top with a V neck and high heels. She had her usual fake glasses on but her hair was falling down in beautiful waves. She had red lips that looked really attractive out of sudden and Oliver had no idea where that thought came from, but he did not hate seeing Kara right now, to be honest.

- It's everything ok?

- Yes! – She smiled, turning to the barman and ordering the same Oliver was having

She noticed the worried look in his face and turned to face him.

- Don't worry, nothing's going on…

- Any crisis?

- No. – She smiled

- Ok then. – He smiled back to her. – It's a nice surprise seeing you here.

- I needed some time off, decided to make a small surprise. – She took two steps closer to him, looking into his eyes with a determined look – I'm tired of meeting friends from… far away only when the world it's about to end.

- I keep telling Barry that.

- So you get me… - She touched his arm – What's wrong about having a little fun from time to time with friends right?

- Nothing wrong – he said, trying to figure it out why Kara was so different. She was being really forward with him and he knew she was not like that, but kept talking normally with her.

Deep down Oliver was glad Kara showed up. He loved Thea and would do anything for her, but this party was really boring to him, full of people he couldn't stand, especially Star City press that he knew hated him. He missed his old self sometimes and decided not to worry now, at least not for tonight. Kara could take care of herself and he knew it, he wanted to know why she was so different now, but he decided not to push it. Maybe she would tell him later.

- I wonder if the Mayor enjoys dancing…

- Not at all!

- C'mon! One won't hurt. – She approached her lips next to his ears – I know you want it.

Kara finished her drink and passed by Oliver. He held her hand, stopping her from keep walking and she smiled at him.

- One. - He said

- Perfect! – She smiled, giving a small pull and bringing him closer to her.

An upbeat song played loudly as people gather together on the dance floor. Oliver held Kara's waist and she put her arms on his shoulders as they moved together in the rhythm of the music.

- So… What about your girlfriend… Felicity? I've noticed you came alone… - She asked looking suggestively at him.

- We broke up – He told her, deciding he wasn't going to lie. She was his friend and lived so far away; there was no reason for him to pretend everything was fine and wonderful with her.

- Ouch. Sorry!

- It's ok.

- What happened?

- She said no to my proposal at Barry's wedding.

- Oh… That's why she had a face like she ate something she hated and threw up? – Kara let a small laugh out of her lips and stopped, just giving Oliver a tiny smile. – It's ok; you can do better than that!

- We are still friends but…

- Things are awkward right? It's always awkward.

- Talking by experience? What about you? Why are you here… all alone – He looked at her as his hands went for her back.

- Long story. But, he went to the future, came back married and now went back to the future with his wife.

- I'm sorry

- That's ok. I can do better than that!

Kara looked at Oliver's lips and he arched an eyebrow, smiling back at her. "Was she flirting with him?" He thought. It looked like it. For some reason he didn't have a problem with that, at all. They were both single and adults, he also thought. Oliver was more than ok to have her flirting with him, he thought. Kara turned around, dancing suggestively, with her back to Oliver's chest. He brought his lips closer to her ear, asking in a low voice.

- It's everything ok with you? I've noticed you are a bit…different…More carefree…

- Don't judge me – She said as she turned around, facing him. Both her hands went for his chest – Since you are being so honest with me today, you deserve the truth. There is this red kryptonite, that can make me feel free, less worried, more like me, you know? The part I try to repress and keep hidden. We all have light and darkness inside of us, I wouldn't actually call it darkness but…freedom. Not ashamed of anything. You know? – She asked with her face inches from his.

- Yes, I know. – He said, just looking back at her.

So it all made sense now but he decided not to judge, for the first time in a long time, and just enjoy the night. He knew the feeling she described way too well. He had darkness inside him, buried, hidden, and was always scared it might surface again. He was just finding it surprising Supergirl, the brightest and cute person on the world, also had it inside her.

To be honest, he knew so little about her, so she might have her reasons just as he had his. They danced together for a while and Kara looked at him once again, reaching for the collar of his coat.

- I'm thirsty. I think a few drinks will do us some good…

- Are you trying to get us drunk?

- Alcohol has zero effect on me

- Oh, so it's me you're trying to get drunk?

- Oh, you found out my evil plan… - She laughed, teasing him. – Get you drunk and…

- And?

- I don't know, you tell me!

Kara turned on her heels and walked towards the bar, Oliver walking right after her. They took a few more shots, of vodka this time.

- I have a huge resistance for vodka, just so you know it – Oliver said as he took his 3rd shot.

- Impressive!

- So… How this red kryptonite works after all?

Kara put her glass on the counter and looked at him, really close.

- It makes me feel all the power I have, it makes me not be afraid to use them if I have to. It makes me deal with my enemies the way I should in my normal state. – She touched his arm again, caressing it slowly – It makes me less naïve and more aware of the world, of who I am, what I can do. It feels great, like I'm finally free of guilt, of sadness, of all the shit I have to take on daily basis. And you see… This is a good thing for you, Emerald Archer – She said the last part in a whisper.

- Why's that? – He asked looking curious at her.

- Because I'm also here to help you take down for good that bastard you are after. Cayden James, isn't it?

- Kara… I'm not killing him.

- And who's talking about killing?

Kara laughed as she walked back to the dance floor, Oliver coming after her.

- I'm talking about making him pay. Making him suffer. – Kara looked at Oliver as she turned around, being insanely closer to him this time, her hands caressing his face – You know what I can do, let me help you. We can have our fun – She smiled as she looked at the conflicted look in his eyes. – We can stop him once and for all, and he won't let anyone else again in this city. He deserves to suffer!

- I couldn't agree more; I'm just worried… About you…

- I can take care of myself Oliver. Like I said, I'm not going to kill the guy. Deep down I want it and you know I can do it quickly, but I won't.

- How do you know about it anyway?

- A red bird told me a while ago…

- Barry… - Oliver lowered his head and Kara touched his chin with her finger, lifting his head up once again.

- He told me the atrocities this guy did, he almost killed your son, and this is not ok Oliver. He needs to pay. And you and I both know a way of doing it, a way he won't forget and won't ever again bother your city. – She brought her lips closer to his ear while caressing softly his arms and chest – I won't judge if you're ruthless like I know you once were… there's nothing wrong with that, I'm also feeling like that right now. We can end this nightmare in seconds if you let me help.

Oliver listened carefully to each and every single one of her words. He also felt her lips dangerously close to his ears and neck, it made him shiver inside and he closed his eyes trying to breathe and keep his cool. Kara was a beautiful woman for sure, and the fact that she could lift a building above her head with a finger, it made her really cool. But he wasn't sure about this new Kara he was meeting now. Something inside him felt thrilled about her ideas, he knew he still had that instinct inside him, but he had to make sure things weren't going to get out of control, if he wasn't going to lose control and kill the guy. More than once he wanted to, but he never acted on it. He survived Prometheus, he would survive this. But truth be told, he could use her help now, even if she was suggesting extreme violence and torture like she was. He had no idea how else he would be able to defeat Cayden; things were worse than ever.

He was aware Kara was trying to seduce him to agree with her plan, he had a lot of experience on this department to recognize it, but again: he wasn't totally against it; he wouldn't even try to deny it to himself. He was feeling more attracted to her by the minute and her attitude towards him wasn't helping at all. She did come all this way to find her freedom, to take a time off of her Earth and help him, so it wasn't a bad idea after all.

Kara never felt more in peace with herself than now. It was wonderful to be away from the drama that was her Earth at the moment. She could bet that her sister and the others would be just fine with her if they could see her now; willingly offering to help someone and do whatever it was necessary, like they say she couldn't. She wanted to kill the bastard she heard about and she didn't even know the guy, never saw him before, but she already knew he was scum. She was a kryptonian, she was an alien way more powerful than anything this jerk could possibly think of and she was excited to use this power and show him he messed with the wrong person. Since she met Oliver, when Dominators invaded, something about him intimidated her. She couldn't stop blushing. And then he was a jerk to her, but she saved him anyways and he apologized. He impressed her because he was just a simple human, and had all that fighting skills and was really smart. He managed to lead a group of people with super powers, so he seemed a great hero to her back then. She wondered if it was a crush she had on him but quickly erased this thought from her mind. She visited Barry once, and they talked about Oliver. Barry told her about a few things in Oliver's life and she could understand him a bit more. The first thing she thought about when she put the red kryptonite ring on was to find him. He was the most powerful human she had ever met and this made her wonder things. They were similar in so many things, she had all of those dark feelings hidden inside her, he had this dark past and darkness inside him, he also tried to hide according to Barry. And she was dying to do something great, something huge that would allow her to let out everything that was burning inside of her. This was a perfect opportunity. Plus, he was hot. She would take all the opportunity she had.

- Please? - She said, looking at him with a look only her could give him. – Let's have our fun!

- No killing!

- Pinky promise! – She smiled, looking intensely at his eyes.

Oliver had reached for the worse people in the past, for help. He did it with Anatoly, with Slade, with Captain Boomerang, with Malcolm. He wasn't going to say no to Kara now, and again, he could use the help. She was the only one who could help him bring the guy down faster than anything else. The proximity of her face and her body to his made Oliver feel thing he hadn't felt in a long time, her slow dancing and the look in her eyes made Oliver stop having any coherent thoughts. He crashed her lips with his, his hand reaching for her neck. Kara responded the kiss passionately and when they stopped the kiss, they both breathed heavily, trying to regain some air. It was a breath taking, deep and passionate kiss that made Oliver lose any restrain he had left. Kara held his cheeks with her hands and smiled at him.

- Meet me in the bunker in five minutes! – She gave him one last kiss and vanished from his sight, leaving him disorientated.

- Wow. – Was all Oliver could say.

Oliver gave some excuse to people that wanted to talk to him at the party and went back to the bunker only to find Cayden James tied up in a chair and Kara standing right on his side, in a full black outfit with her famous symbol in silver, on her left chest.

- I told you we can bring him down easily with my help – She smiled as she patted Cayden's shoulders with a bit more strength, making him wake up and look scared at Oliver for the first time.

- Mr. Queen, may I know who is this?

- You need to shut up! – Kara said turning around and looking angrily at him – Or do you want to sleep for good this time?

- Kara…

- Chill Oliver! You know what I mean – She laughed and blinked at Oliver, turned her attention back to Cayden.

- This one was telling me how he was going to tear me apart and give my parts to the dogs… Can you believe this guy? – Kara laughed as she pointed at Cayden. – Imagine his surprise when he found out I was not from around… And not that easy to break?

Kara kicked his chair, making it fly around the room and hit the wall. The chair fell to its side, making Cayden's face hit the ground. Kara walked to him and stepped her foot on his cheeks.

- This is how you threat woman, Mr. James?

- He threats everyone like that! – Oliver said as he approached them.

- Hum… - Kara said, putting a bit more of pressure in her feet. – Do you know I can make your face become ashes under my boots? So I think it's better if you shut your mouth and never again threaten me or anyone else! Now… I believe Oliver has something to tell you.

Kara grabbed him with the chair and took him from the ground, making the chair break with a single pull from her. Cayden stood up, all tied up.

- Cayden… Someone played you to get even at me… I was not the one that killed your son.

- I'm sorry Mr. Queen, but I don't believe you.

- I was in Hub City that night. – He yelled at Cayden taking a few steps towards him.

- It's a shame you don't believe Oliver – Kara said. – Do you think he is a scum like you are? – She laughed closing her fists.

She stared at his shoulders, her heat vision hitting straight into his bones, burning him deeply. Cayden let out a yell, feeling a lot of pain, but refusing to back down. He just smiled at the two of them.

- Mr. Queen understands better than anyone how much a father cares for their children. He took mine from me, so it's only fair I do the same with him. He can have strong allies like yourself nice lady, but I do too. And you know what will happen? – He looked calmly as it was nothing he was discussing with them – My friends have orders kill Thea and William if something ever happens to me.

- I figured you would do something like that… - Kara said, looking at how angry Oliver got in seconds.

She vanished from their sight and came back exactly one minute later.

- Oliver's loved ones are all safe, I'm sorry to break it to you…

Cayden looked at Kara with wide eyes. Oliver never saw him like that and the simple presence of Kara in the room made him shake in fear. "Good", he thought.

Oliver felt his old self resurfacing little by little. There were no limits in what Oliver would do if someone threatened his loved ones. He looked furious at Cayden, breathing in and out while Kara talked to him. Kara held Cayden's head with her hands and squeezed it a bit.

- Do you know how it feels to have the power over someone's life in your hands? To decide if they live or die? It's amazing – She laughed as she pressed a bit her hands around his head. – Not so brave right now, huh? No one will do anything for you, or come to rescue you because I took care of them…in 2 seconds.

- Kara…

- They are alive – She looked at Oliver smiling and turned her attention to Cayden – But their bones…

Oliver heard what Kara said and couldn't feel anything but proud of her. The new him would not approve torture or extreme violence, but it was a terrorist they were dealing with, someone trying to hurt his loved ones. Right now, he couldn't care less. He tried being merciful with bad guys in the past and it cost the lives of people he loved. He promised himself this would never happen again, and he would keep that promise.

- Kara, please let me deal with Cayden James now!

He said in a serious and deep tone that gave chills even in Kara. She was thrilled to finally see the dark side of Oliver surfacing. She took a few steps away, near Oliver and reached for his shoulders.

- Don't hold back.

- I won't!

Oliver walked towards Cayden and gave him a satisfied smile.

- Your days terrorizing this city are over!

Oliver wasted no time, his fists hitting every single side of Cayden's face he could reach. He started punching his chest, his stomach. He lifted his foot giving a strong kick on his knee and a huge crack noise could be heard from miles away.

- Ouch! – Kara laughed watching Oliver beating the guy up.

Oliver grabbed Cayden's right arm, letting it out of the ropes just so he could twist it to his back, pushing it in an angle that was impossible not to break.

Another crack was heard.

Oliver kept breaking every single bone of Cayden's body he could reach, the room filled with crack noises and Cayden's yelling in pain. Oliver's hand was full of blood and he couldn't care less.

Both Oliver and Kara muted Cayden's screams on their ears. Oliver's rage was beyond anything he ever felt before, and he was determined to make him stop at any costs.

- First I break you, and then you will spend the rest of your life locked down, deep down in Argus.

- Barry told me about a half man half shark that is there. I think he would love some company… Maybe food? – Kara smiled as Cayden looked at her with his blooded face.

- I will…

- You will do nothing! – Kara flew high on the sky and grabbed him by the collar, throwing him to the other side of the room, making his back hit the wall. – Oliver will, and you will shut up or it will be worse to you!

Oliver walked towards Cayden, giving him one punch, one kick after another. Oliver finally had enough, kneeling on the floor, exhausted. Kara came floating on the air and looked at the terrified look in Cayden's face.

- We will come for your friends by the way. Just know this reign of terror of yours is over! And you know what? I just faced a world killer on my Earth, a kryptonian like me hell bent on destroying everything. She gave me a hard time but you… You were never so easy to take down! – She gave Cayden a half smile, using her heat vision on his other shoulder until it created a hole on it and he bleed even more.

Cayden James was destroyed. He was breathing, hardly, but was. No one could recognize him if they saw the state Oliver and Kara left him. Oliver got up from the floor and looked at the scene, feeling zero remorse. Now he could be thrown at ARGUS prison and never mess with anyone else.

- Thank you – He looked turned to Kara, looking at her still with a serious face.

- You were ruthless. So brutal… - She told him as she walked closer to him as Cayden James passed out from the pain he was in.

- I know this red kryptonite thing changed you. But I won't be the one to judge your need to feel this kind of freedom, embracing all you can do. Because I feel the same way sometimes, and no one can understand it. Somehow I feel you can.

- Yes, I can.

- And sometimes I do what's necessary, even if not everyone likes it. And you were a great help today. I had no idea how to stop him. You helped, so thank you.

- Thank you for not trying to change me back. The last time it happened, things got ugly, people wouldn't understand. I can control it more now, my powers, my desires, my want to make others suffer. I want to, but I cannot kill, like I told you. And you trusted this. I am the one who needs to thank you…

Oliver dialed Diggle, telling him they got Cayden. Diggle warned he and Lyla would be there right away to take the guy to ARGUS prison.

- Why here? – He looked at Kara, wanting some answers, but also wanting to kiss her again.

- I knew somehow you would accept this side of me… And not lock me away until someone could come and bring me back. I felt I could trust you. And it would be fun to take my anger at someone who deserved.

Oliver took a step closer to Kara, approaching his lips to hers.

- We are a powerful team, Oliver. – She whispered, closing the space between them when they heard a noise and stood apart from each other.

- Oliver? – Lyla said as she entered the bunker and looked horrified at Cayden James.

- What happened, man? – Diggle looked worried at Oliver.

- We just made sure he won't hurt anyone ever again.

- He is alive – Kara said in an innocent voice.

Diggle nodded at them, still worried, but he decided to talk to Oliver later. He helped his wife pick the guy from the floor and take him away. Once they were out, Oliver walked back towards Kara, grabbing her by the waist and lifting her to sit on the table, as he closed the space between them, standing between her legs.

- Yes, we do. – He said in a whisper – Are you ready to get your hands a bit dirtier?

- Always! – She smiled excitedly as Oliver gave her one more breath taking kiss.

- One down, two to go!

Her best friend, Lena Luthor, hated her with all her strength. She found out Kara Danvers and Supergirl were the same person and felt betrayed, so much she cut all ties she had with Kara or Alex, and fired her from CatCo. She still remembered her harsh words.

FLASHBACK

- I guess I can finally understand my brother and his hatred for Superman. You aliens think you are above us; you don't actually trust us you just use us for whatever you need. While we believe we have real friends to count on, you lie behind our backs! I was never your friend was I? I was just someone you could use, you could make a fool of, but you never really considered me as your friend. You fooled me Kara, you made me feel like a fool. I see what my mother sees now. I can't blame her for being the way she is. It's just a matter of time before you get sick of us and turn your back on humanity, how can I be sure it won't happen? How can I trust you, if you never really trusted me?"

END OF FLASHBACK

Lena's words echoed through Kara's ears every day since this happened.

And right after it, there was her battle with Reign. One more thing that made Kara feel awful and hurt like never before.

Reign killed her dear friend, James, which made Lena way more pissed, hurt and angry than she was before with Kara. She blamed her for not doing what was necessary to help James. Alex was also mad at her. Alex told her Reign wasn't going to have mercy on them and Kara believed she could still reach her. It was Sam for Rao's sake, their friend. Alex saw no hope for her, but Kara insisted she wasn't going to kill her. Alex begged her to, and Reign ended up killing James. Winn was so sad he vanished and no one could find him. Alex and J'onn joined forces and managed to take her down, after Alex almost got killed as well. Their fight was so awful, Kara couldn't take it and flew away and now she was here, in space, floating and thinking about all the awful things that happened.

She flew back to her apartment in super speed and went directly to the drawer in her bedroom. She picked up a small box and opened it. There it was, a ring of red kryptonite someone left at her door once and she decided to hide it, just in case. She looked again at her drawer and picked up her extrapolator, smiling to herself as she put the ring on and opened a breach.

She needed some time off, some freedom. And she was going to get it!

Oliver hated those kind of parties, but at least it was not in a boring place. Thea managed to reopen Verdant, but in another part of the city. She decided it was going to be a different nightclub, more sophisticated and Oliver gave her all his support. He had to be there as the city's Mayor, dealing with annoying people who wondered why he was supporting a nightclub again when the last time he tried, it failed big time.

Thank God at least William understood more about what he did, and was more supportive. It was one less stress in his life.

He was drinking scotch and he felt a hand on his shoulders and turned around, looking surprised at the person standing before him.

- Kara?

- The one and only! – She smiled to him in such a way that made him feel hypnotizes for a second.

- It's everything ok?

- Yes, never better! – She smiled, turning to the barman and ordering the same Oliver was having

She noticed the worried look in his face and turned to face him.

- Don't worry, nothing's going on...

- Any crisis?

- No. – She smiled

- Ok then. – He smiled back to her. – It's a nice surprise seeing you here.

- I was needing some time off, decided to make a small surprise. – She took two steps closer to him, looking into his eyes with a determined look – I'm tired of meeting friends from... far away only when the world it's about to end.

- I keep telling Barry that.

- So you get me... - She touched his arm – What's wrong about having a little fun from time to time with friends right?

- Nothing wrong – he said, trying to figure it out why Kara was so different. She was being really forward with him and he knew she was not like that, but kept talking normally with her.

- I wonder if the Mayor enjoys dancing...

- Not at all!

- C'mon! One won't hurt. – She approached her lips next to his ears – I know you want it.

Kara finished her drink and passed by Oliver. He held her hand, stopping her from keep walking and she smiled at him.

- One. He said

- Perfect! – She smiled, giving a small pull and bringing him closer to her.

The music was not slow but also not that energetic. Oliver held Kara's waist and she put her arms on his shoulders as they moved together in the rhythm of the music.

- So... What about your girlfriend... Felicity? I noticed you came alone... - She asked looking suggestively at him.

- We broke up – He told her, deciding he wasn't going to lie. She was his friend and lived so far away, there was no reason for him to pretend everything was fine and wonderful with her.

- Ouch. Sorry!

- It's ok.

- What happened?

- She said no to my proposal at Barry's wedding.

- Oh... That's why she had a face like she ate something she hated it and threw up? – Kara let a small laugh out of her lips and stopped, just giving Oliver a tiny smile. – It's ok, you can do better than that!

- We are still friends but...

- Things are awkward right? It's always awkward.

- Talking by experience? What about you? Why are you here... all alone – He looked at her as his hands went for her back.

- Long story. But, he went to the future, came back married and now went back to the future with his wife.

- I'm sorry

- That's ok. I can do better than that!

Kara looked at Oliver's lips and he arched an eyebrow, smiling back at her. Was she flirting with him? He thought. It looked like it. For some reason he didn't have a problem with that, at all. They were both single and adults, he thought. He was more than ok to have her flirting with him, he thought. Kara turned around, dancing suggestively, with her back to Oliver's chest. He brought his lips closer to her ear, asking in a low voice.

- It's everything ok with you? I noticed you are a bit...different...More carefree...

- Don't judge me – She said as she turned around, facing him. Both her hands went for his chest – Since you are being so honest with me today, you deserve the truth. There is this red kryptonite, that can make me feel free, less worried, more like myself you know? The part I try to repress and keep hidden. We all have light and darkness inside us, I wouldn't actually call it darkness but...freedom. Not ashamed of anything. You know? – She asked with her face inches from his.

- Yes, I know. – He said, just looking back at her.

So it all made sense now. He decided not to judge, for the first time in a long time, and just enjoy the night. He knew the feeling she described way too well. He had darkness inside him, buried, hidden, and was always scared it might surface again. He was just finding it surprising Supergirl, the brightest and cute person on the world, also had it inside her.

To be honest, he knew only a little about her, so she might have her reasons just as he had his. They danced together for a while and Kara looked at him once again, reaching for the collar of his coat.

- I'm thirsty. I think a few drinks will do us some good...

- Are you trying to get us drunk?

- Alcohol has zero effect on me

- Oh, so it's me you're trying to get drunk?

- Oh, you found out my evil plan... - She laughed, teasing him. – Get you drunk and...

- And?

- I don't know, you tell me!

Kara turned on her heels and walked towards the bar, Oliver walking right after her. They took a few more shots, of vodka this time.

- I have a huge resistance for vodka, just so you know it – Oliver said as he took his 3rd shot.

- Impressive!

- So... How this red kryptonite works after all?

Kara put her glass on the counter and looked at him, really close.

- It makes me feel all the power I have, it makes me not be afraid to use them if I have to. It makes me deal with my enemies the way I should in my normal state. – She touched his arm again, caressing it slowly – It makes me be less naïve and more aware of the world, of who I am, what I can do. It feels great, like I'm finally free of guilt, of sadness, of all the shit I have to take on daily basis. And you see... This is a good thing for you, Emerald Archer – She said the last part in a whisper.

- Why's that? – He asked looking curious at her.

- Because I'm also here to help you take down for good that bastard you are after. Cayden James isn't it?

- Kara... I'm not killing him.

- And who's talking about killing?

Kara laughed as she walked back to the dance floor, Oliver coming after her.

- I couldn't agree more; I'm just worried... About you...

- I can take care of myself Oliver. Like I said, I'm not going to kill the guy. Deep down I want it and you know I can do it quickly, but I won't.

- How do you know about it anyway?

- A red bird told me a while ago...

- Barry... - Oliver lowered his head and Kara touched his chin with her finger, lifting his head up once again.

- He told me the atrocities this guy did, he almost killed your son, this is not ok Oliver. He needs to pay. And you and I both know a way of doing it, a way he won't forget and won't ever again bother your city. – She brought her lips closer to his ear while caressing softly his arms and chest – I won't judge if you're ruthless like I know you once were... there's nothing wrong with that, I'm also feeling like that right now. We can end this nightmare in seconds if you let me help.

Oliver listened carefully to each and every single one of her words. He also felt her lips dangerously close to his ears and neck, it made him shiver inside and he closed his eyes trying to breathe and keep his cool. Kara was a beautiful woman for sure, and the fact that she could lift a building above her head with a finger, it made her really cool. But he wasn't sure about this new Kara he was meeting now. Something inside him felt thrilled about her ideas, he knew he still had that instinct inside him, but he had to make sure things weren't going to get out of control, if he wasn't going to lose control and kill the guy. More than once he wanted to, but he never acted on it. He survived Prometheus, he would survive this. But truth be told, he could use her help now even if she was suggesting extreme violence and torture like she was. He had no idea how else he would be able to defeat Cayden; things were worse than ever.

He was aware Kara was trying to seduce him to agree with her plan, he had a lot of experience on this department to recognize it, but again: he wasn't totally against it, he wouldn't even try to deny it to himself. He was feeling more attracted to her by the minute and her attitude towards him wasn't helping at all. She did come all this way to find her freedom, to take a time off of her Earth and help him, so it wasn't a bad idea after all.

Kara herself never felt more in peace with herself than how she felt now. It was wonderful to be away from the drama that was her Earth right now. She could bet that her sister and the others would be just fine with her if they could see her now, willingly offering to help someone and do whatever it was necessary, like they say she couldn't. She wanted to kill the bastard she heard about and she didn't even know the guy, never saw him before, but she already knew he was scum. She was a kryptonian, she was an alien way more powerful than anything this jerk could possibly think of and she was excited to use this power and show him he messed with the wrong person. Since she met Oliver, when Dominators invaded, something about him intimidated her. She couldn't stop blushing. And then he was a jerk to her, but she saved him anyways and he apologized. He impressed her because he was just a simple human, and had all that fighting skills and was really smart. He managed to lead a group of people with super powers, so he seemed a great hero to her back then. She wondered if it was a crush she had on him but quickly erased this thought from her mind. She visited Barry once, and they talked about Oliver. Barry told her about a few things in Oliver's life and she could understand him a bit more. The first thing she thought about when she put the red kryptonite ring on was to find him. He was the most powerful human she had ever met and this made her wonder things. They were similar in so many things, she had all of those dark feelings hidden inside her, he had this dark past and darkness inside him he also tried to hid according to Barry. And she was dying to do something great, something huge that would allow her to let out everything that was burning inside of her. This was a perfect opportunity. Plus, he was hot. She would take all the opportunity she had.

- Please? - She said, looking at him with a look only her could give him. – Let's have our fun!

- No killing!

- Pinky promise! – She smiled, looking intensely at his eyes.

Oliver had reached for the worse people in the past, for help. He did it with Anatoly, with Slade, with Captain Boomerang, with Malcolm. He wasn't going to say no to Kara now, and again, he could use the help. She was the only one who could help him bring the guy down faster than anything else. The proximity of her face and her body to his, her slow dancing and the look in her eyes made Oliver stop having any coherent thoughts. He crashed her lips with his, his hand reaching for her neck. Kara responded the kiss passionately and when they stopped the kiss, they both breathed heavily, trying to regain some air. It was a breath taking, deep and passionate kiss that made Oliver lose any restrain he had left. Kara held his cheeks with her hands and smiled at him.

- Meet me in the bunker in five minutes! – She gave him one last kiss and vanished from his sight, leaving him disorientated.

- Wow. – Was all Oliver could say.

- I told you we can bring him down easily with my help – She smiled as she patted Cayden's shoulders with a bit more strength, making him wake up and look scared at Oliver for the first time.

- Mr Queen may I know who this is?

- You need to shut up! – Kara said turning around and looking angrily at him – Or do you want to sleep for good this time?

- Kara...

- Chill Oliver! You know what I mean – She laughed and blinked at Oliver, turned her attention back to Cayden.

- This one was telling me how he was going to tear me apart and give my parts to the dogs... Can you believe this guy? – Kara laughed as she pointed at Cayden. – Imagine his surprise when he found out I was not from around... And not that easy to break?

Kara kicked his chair, making it fly around the room and hit the wall. The chair fell to its side, making Cayden's face hit the ground. Kara walked to him and stepped her foot on his cheeks.

- This is how you threat woman, mr James?

- He threats everyone like that! – Oliver said as he approached them.

- Hum... - Kara said, putting a bit more of pressure in her feet. – Do you know I can make your face become ashes under my boots? So I think it's better if you shut your mouth and never again threaten me or anyone else! Now... I believe Oliver has something to tell you.

Kara grabbed him with the chair and took him from the ground, making the chair break with a single pull from her. Cayden stood up, all tied up.

- Cayden... Someone played you to get even at me... I was not the one that killed your son.

- I'm sorry mr Queen, but I don't believe you.

- I was in Hub City that night. – He yelled at Cayden taking a few steps towards him.

- It's a shame you don't believe Oliver – Kara said. – Do you think he is a scum like you are? – She laughed closing her fists.

- Mr Queen understands better than anyone how much a father cares for their children. He took mine from me, so it's only fair I do the same with him. He can have strong allies like yourself nice lady, but I also have. And you know what will happen? – He looked calmly as it was nothing he was discussing with them – My friends have orders kill Thea and William if something ever happens to me.

- I figured you would do something like that... - Kara said, looking at how angry Oliver got in seconds.

She vanished from their sight and came back exactly one minute later.

- Oliver's loved one are all safe, I'm sorry to break it to you...

Cayden looked at Kara with wide eyes. Oliver never saw him like that and the simple presence of Kara in the room, was making him shake in fear. Good, he thought.

Oliver felt his old self resurfacing little by little. There were no limits in what Oliver would do if someone threatened his loved ones. He looked furious at Cayden, breathing in and out while Kara talked to him. Kara hold Cayden's head with her hands and squeezed it a bit.

- Kara...

- They are alive – She looked at Oliver smiling and turned her attention to Cayden – But their bones...

Oliver heard what Kara said and couldn't feel anything but proud of her. The new him would not approve torture or extreme violence, but it was a terrorist they were dealing with, someone trying to hurt his loved ones. Right now, he couldn't care less. He tried being merciful with bad guys in the past and it costed the lives of people he loved. He promised himself this would never happen again, and he would keep that promise.

- Kara, please let me deal with Cayden James now!

- Don't hold back.

- I won't!

Oliver walked towards Cayden and gave him a satisfied smile.

- Your days terrorizing this city are over!

- Ouch! – Kara laughed watching Oliver beating the guy up.

Oliver grabbed Cayden's right arm, letting it out of the ropes just so he could twist it to his back, pushing it in an angle that was impossible not to break.

Another crack was heard.

Oliver kept breaking every single bone of Cayden's body he could reach, the room filled with crack noises and Cayden's yelling in pain. Oliver's hand was full of blood and he couldn't care less.

Both Oliver and Kara muted Cayden's screams on their ears. Oliver's rage was beyond anything he ever felt before, and he was determined to make him stop at any costs.

- First I break you, then you will spend the rest of your life locked down, deep down in Argus.

- Barry told me about a half man half shark that is there. I think he would love some company... Maybe food? – Kara smiled as Cayden looked at her with his blooded face.

- I will...

- We will come for your friends by the way. Just know this reign of terror of yours is over! And you know what? I just faced a world killer on my Earth, a kryptonian like me hell bent on destroying everything. She gave me a hard time but you... You were never so easy to take down! – She gave Cayden a half smile, using her heat vision on his other shoulder until it created a hole on it and he bleed even more.

- Thank you – He looked turned to Kara, looking at her still with a serious face.

- You were ruthless. So brutal... - She told him as she walked closer to him as Cayden James passed out from the pain he was in.

- Yes, I can.

- And sometimes I do what's necessary, even if not everyone likes it. And you were a great help today. I had no idea how to stop him. You helped, so thank you.

Oliver dialed Diggle, telling him they got Cayden. Diggle warned he and Lyla would be there right away to take the guy to ARGUS prison.

- Why here? – He looked at Kara, wanting some answers, but also wanting to kiss her again.

- I knew somehow you would accept this side of me... And not lock me away until someone could come and bring me back. I felt I could trust you. And it would be fun to take my anger at someone who deserved.

Oliver took a step closer to Kara, approaching his lips to hers.

- We are a powerful team, Oliver. – She whispered, closing the space between them when they heard a noise and stood apart from each other.

- Oliver? – Lyla said as she entered the bunker and looked horrified at Cayden James.

- What happened, man? – Diggle looked worried at Oliver.

- We just made sure he won't hurt anyone ever again.

- He is alive – Kara said in an innocent voice.

- Yes, we do. – He said in a whisper – Are you ready to get your hands a bit dirtier?

- Always! – She smiled excitedly as Oliver gave her one more breath taking kiss.

- One down, two to go!

NOTES 2:

Spoiler Alert:

Prompt from WritersBlock039: "five times Oliver and Kara were scared to tell the other they loved them, and the one time no supervillain could have stopped them from telling each other. Can be episode compliant, doesn't have to be."
