Chapter Summary: Prompt by: Guest4587: OMG now I definitely wanna see MORE interaction between Oliver and Red Daughter... Maybe even a bit of romance? I Ship It!

.

The noise of swords cutting the air, hitting each other echoed through all over the place. She was more than willing to prove she was an even better fighter than before, a true soldier. She had anger in her eyes and a thirst that could only be fulfilled when she was ripping other people skin and taking their blood.

She was a naïve girl once, now she was ruthless.

Cruel.

She was about to perform her best move, when they all heard a noise.

- Wait. I'll see what's going on. – Her master said, turning around and walking towards the entrance.

As soon as he walked out, he got ready to fight whoever that was.

A blonde woman, looking really young and only wearing a blanket stood before him. She had confusion written all over her face.

- Who are you? – He asked.

- I'm... Kara.

- What are you doing here?

- I don't know – She said looking around. – I just found this place.

A bunch of guys wearing black, hoods and masks appeared ad tried to attack her. By instinct, she focused her gaze on each and every one of them, red rays coming from her eyes and hitting them, making them drop dead on the ground. The man looked at her and smiled.

- Nice to meet you Kara, I'm Ra's Al Ghul!

4 YEARS LATER.

Kara came back to Nanda Parbat after a League mission. For years she had been living with them, training with them. She became a cold blooded assassin, they convinced her they were doing a good thing, but she was getting tired of it all, little by little. The only one that seemed to understand her, was the blonde woman she got to know and be close, Ta-er al-Sahfer, Sara Lance.

- So how was it? – Sara asked when Kara came in, noticing something was wrong with her.

- As usual... Blood everywhere.

- It's a League thing.

- And I'm tired of it... Aren't you? – She looked at Sara with a questioning look.

- To be honest... - Sara said as she came closer – A bit tired, yes. But for now, you know the rules.

- Yes, I know... - Kara looked down feeling frustrated. She turned around and went to her chambers, not looking back while Sara kept staring at her with curious eyes.

STAR CITY

He looked around; having the feeling that something was off. He saw Laurel, looking at him defiantly as she told him about how he wasn't going to be able to escape justice.

Damn it, he thought.

Many flashlights aimed at him and he knew he was surrounded, and this time it wasn't on his plans, so he wasn't actually sure how he was going to be able to run away. He was still aiming at the cops when a loud noise could be heard from the ceiling and it seconds a crater opened on it. A blonde woman with a black and thick bodysuit, a black and red cape and a red S on her chest landed on the ground, grabbed him and flew away.

Even the police got confused by that, trying to see her face, but couldn't because half of it was covered with a black mask.

She flew far away from SCPD and landed in an abandoned rooftop, letting Oliver go. He jumped to the ground and looked back at her, trying to identify who was that woman.

- Who are you and why did you save me?

She didn't answer and flew away, leaving a pissed Oliver behind.

Oliver was determined to find out who that was, so he asked Diggle and Felicity to get him more information. On many occasions, she appeared where Oliver was, and he was starting to think she was following him, until one day, he prepared a trap and she fell right on it. He got her trapped on wires and smiled to himself.

- I will ask you one more time, who are you? – He said while he approached her, cautiously.

- A friend.

- Funny cause friends usually tell us their names, so start talking!

She looked around, hearing something and looked back at Oliver, with a look of concern.

- This is not the place for us to have this conversation...Someone's coming...

She broke free from the wires, making Oliver jump in scare, grabbed him again and flew away from there with him. After a while, they landed on another rooftop after she made sure it was safe.

- You need to stop doing this... - He said taking deep breaths to recover from the sudden trip.

- I'm sorry but we had to get out of there.

- Why?

- Not of your business...

- You have been following me around for weeks now, so yeas, it is my business!

She took a deep breath and took the mask covering her mouth and nose off.

- I can't tell you who I am, because I don't know! All I know is that my name is Kara. And there are people after me!

- Who's after you? Let me help you. You saved me the other day, it's seems fair.

Kara considered it for a minute and crossed her arms. She knew deep down she could tell him at least something, if this was really him.

- You're Oliver Queen?

Oliver stared in shock at her. There was no way she could know who he was.

- I know you're Oliver Queen!

- How?

- If I told you, you wouldn't believe me!

- Try me!

- Someone you know is worried about you and I couldn't help but check on you. And I was right, since I saved your ass twice already.

- Who's that someone?

- You ask too many questions! – She looked annoyed at him. – Do you... Know the League of Assassins?

- I've heard of them... An urban legend.

- A real threat. All you need to know is that they are after me! That's why we had to get out of there today. I'm powerful but they have means to stop me and also could hurt you.

- So we deal with them...

- I deal with them.

- They're on my city, we deal with them!

Oliver introduced Kara to Felicity, Diggle and Roy after he joined them on the bunker to help stop the crimes on Star City. He explained what was happening and they tried their best to find out the league members that were after Kara.

- Man, why the League is after her? – Diggle asked Oliver.

- Because I ran away – Kara said approaching them – super hearing – She pointed at her ears – I'm sorry.

- That's new... - Diggle looked curious at her – What else can you do?

- Fly, I have super strength, x ray vision, heat vision, freeze breath, enhanced vision, super speed, endless stamina, I'm bulletproof, they used to call me the girl of steel.

Felicity, Diggle and Roy looked startled at Kara.

- I'm impressed! – Diggle commented and Felicity nodded

- I'm sorry, but how can they be after you with all of that power? – Roy asked, trying to make all of that make sense.

- They know about the one thing that can hurt me. They have it and they will use it until I go back, and I don't want to go back! I rather die!

- You won't have to go back, I promise. We will help you – Oliver said as he reached for her shoulder.

Kara smiled and nodded with her head. She was right about trusting Oliver in the first place. She heard Sara talking about him so many times, and how she was worried he would get himself killed with this vigilante thing. She has been to Star City a few times, to keep an eye on her sister Laurel, so she was aware about Oliver being the vigilante; she had seen that hood before on Lian Yu. She cared about Sara deeply, and couldn't help but see if he was ok and that was when she saved him from the cops. She had a feeling he needed help and she was right. And now she was the one needing help and something told her she could count with that weird team of vigilantes. Even if they were up against highly trained assassins who could knock her out in seconds with kryptonite.

After managing to catch the two League members that were after her, Kara warned the one who survived to warn Ra's she would never come back. She had made up her mind and never wanted to go back to the life she had before, she was ready to start over, maybe join Oliver and his team on their fight. She still had nowhere to go, spending nights flying from rooftop to rooftop, watching as the city slept. But she was determined.

She tried to keep a lot to herself, not letting anyone from team Arrow know more about her than they needed to know. She didn't know that much about her as well, so there was no point. She told them she had a place, but one night, Oliver caught her on a building and found out she lied.

- Kara, this is no life.

- Is better than the one I had before.

- I won't leave you here... C'mon, we have plenty of bedrooms for a reason.

- Helping homeless aliens? – She teased

- You know what I meant... Also... Are you?

- An alien? Yes. That's the other thing I know about me.

- Cool – He smiled at her, offering his hand.

Kara walked towards Oliver, considering his offer. She had nothing to lose anyways, and she could handle anything that came her way so she started walking with him.

- Missed me?

Kara and Oliver turned around only to see a blonde woman in a black suit, black mask and a silver bo-staff on her hand. Oliver prepared to shoot an arrow, but Kara reached for his hand, making him lower it. She walked towards the blonde, with surprise written all over her face.

- Why did you leave without a word? – The blonde asked.

- I had to. – Kara said. – I can't be back there.

- I know. I can't either.

She reached for Kara's cheeks, bringing her closer and giving her a small kiss. Their foreheads touched and Kara let out a deep breath.

- Nothing has changed.

- I know. This was a last kiss. – She smiled at Kara.

Oliver kept staring at the two of them, feeling a mix of emotions. He looked deep into that blonde's eyes, having a familiar feeling. He walked closer to her.

- Hi, Ollie!

She took her wig and mask and Oliver looked in shock at her. He couldn't believe that was really happening and that it was really her staring at him.

- Sara?

Back in the bunker, Kara and Sara told team Arrow about everything they could, how they met, what happened to Sara after the island, how Kara showed up at Nanda Parbat and had no idea where she came from, only that she had powers. She told them how the League tested her with their ancient ways to find out she wasn't human and how she spent years doing their dirty work.

- And then, I was tired. Tired of all the killing, all the violence. I felt I could do more, that I could be more and that what the League did was wrong. I could tell you felt the same... - Kara said as she looked at Sara.

- So... You hooked up in the past – Felicity pointed at Oliver and Sara – And then you got together – She pointed at Kara and Sara – Weirdest romcom ever, except it has killing and blood and... I'll shut up now. – She said as she noticed the look Oliver gave her.

- Sara, you need to tell your family you are alive... They deserve to know it.

- Ollie, please don't tell them anything yet... I need time... Please. When I'm ready, I'll talk to Laurel, mom and dad.

- Ok... Just don't take it so long to do it, they are suffering... They need you – Oliver said as he looked serious at her. – And... What you will do now?

- I met the daughter of the guy that died on Lian Yu, in that accident with that plane. I swore to him I would find her and look out for her, and that's what I have been doing every time I came back to the city...

- You have been keeping an eye on Laurel, and your dad... - Oliver said.

- Yes, since the Undertaking. I was worried something could happen to them. I was also worried about you; I knew right away you were the hood.

- You should have reached out...

- I couldn't, Ollie. I was active on the League; I couldn't risk it. – Sara said as she grabbed her mask and wig – Well, I gotta go now, I have to check up on Sin... And don't worry, like you, I have a secret lair...

- You can come to the mansion.

- No, thanks. I can't risk people seeing me yet. – Sara said as she waved them goodbye, put her wig and mask on and left.

Diggle and Felicity left Kara and Oliver at the bunker after a few hours talking and checking the city. Oliver looked worried at Kara. He could recognize that look anywhere because he had the same one once.

- I get it. – He said and she looked at him. – I had dark days as well, I had to do a lot of things I'm not proud of... I can help you.

- How? I did horrible things. I left the League because it was so horrible, but I also am horrible, for everything I did. How can I escape that? And I feel pissed because of that and it makes me lose control. I don't want that.

- You can. I did, so can you. I can help you channeling your feelings so you don't lose control anymore...

- Tell me about it... - Kara said as she sat in a chair and Oliver sat across her – About the island.

Oliver started telling her about the most terrible things he had done to survive, sometimes because he wanted and how he killed many people in his first year as Star City vigilante and how it haunted him in his dreams.

- I fought Tommy right before he died, he called me a killer. A monster. And once I heard those words from him, I realized I didn't want to be seen like that. When he died, he called me a hero, so I decided I would honor him. It's not easy, but I'm trying.

- This is inspiring, Oliver... I just hope I have the same strength inside to be better.

- You have amazing powers, Kara. Sadly, you ended up in a place that people abused that and made you use it for the worst things but you can turn it around; use your powers to make good things, help people. It's never too late.

The next few weeks, Kara dedicated her free time to train with Oliver. She didn't use her powers, not even once, and easily beat him up. Oliver was thrown on the floor and looked at her, with pain but a smile on his face.

- You are good.

- I had a good training, despite everything... - She said, reaching for his hand and helping him get up.

- Let's do it again. – He said, getting ready to have his ass whooped one more time by her.

The second time around, Oliver managed to hang on a bit longer than before. He felt his back hit the ground again, knowing he would have bruises, but at least he was making sure of everything Kara knew in fighting, to be able to help her.

With Moira in prison, Thea in her boyfriend's house all the time, that huge mansion ended up with only Kara and Oliver living on it. Oliver insisted for Sara to stay with them for a while and she kept refusing it, until she told her dad the truth. She still refused to go home with him because Laurel and her mom didn't know yet.

Kara was still getting used to the Queen Mansion. Nanda Parbat was a cold place, with nice bedrooms but an ancient ambience that gave her chills all the time. The mansion was really comfy, the bedroom she was in was really huge, had a balcony with an amazing view to the garden, a bathroom with a huge bath tube.

It was really late at night, rained a lot and thunder could be heard from the distance. Kara walked alone around that huge Mansion, knowing for sure she saw shadows moving, like someone was watching her. She tried using her x ray vision and saw someone walking around the living room. She wasted no time, using her super speed to get there. It was a League member. She saw a small green rock on his hand and before it could have any effect on her, she used her heat vision, literally melting his hand.

- I WON'T GO BACK! – She yelled, using her heat vision again, this time killing the guy for good.

Kara jumped from the bed, her heat vision hitting the wall, making the painting fall down. Oliver opened the door of the room, looking worried at Kara as he came in in a hurry.

- Are you ok? What happened?

- I think... - She said with her hand in her chest, feeling her heart almost jump from inside – I think it was a nightmare... I'm sorry about your painting...

- It's ok. – He looked at it on the ground – It's an ugly piece my mom bought once, I'm glad I have a reason to throw it away now – He teased, coming closer and sitting on the bed, next to her. – Are you sure you are ok?

- I think so...

- Do you want to talk about it?

- Not really... Not now... - She said as she stared into his eyes. – I'm sorry I woke you...

- Its ok, Kara. I'm glad you are ok. – He smiled at her. – And if you want to talk, anytime, I'm here for you...

- I appreciate it.

Kara thought about her life and how it all turned upside down so quickly. She had no idea how was her life before getting to Nanda Parbat, and even if she hated everything about that place, she knew it was meant to happen. She wouldn't be here now if it wasn't for that. She just wished her nightmares would go away.

Talking to Oliver calmed her little by little. She found out it was easy to talk to him, maybe because they both had darkness in their past and understood each other, they both had traumas they wanted to forget, they both wanted to be better and move on.

Oliver felt warmth inside of him when he talked to Kara. It was really hard for him to trust people and the day they met, he wasn't sure he could or what her intentions were but now, he could tell she was suffering and wanted nothing more than to be rid of this suffering. He couldn't help thinking they were very similar, despite her being a super powered alien, but he could relate to what she was going through. It made him feel closer to her than anyone he had ever met before. It made him feel less alone. He knew he wasn't alone, because she was there and he knew he could help her.

- We will make it through... The darkness – He said, staring back into her deep blue eyes.

She looked down at him, noticing he was shirtless and blushed. She had a mix of feelings inside of her that she couldn't explain but even so, her face got closer to his and she felt his fingers touching her cheeks. She closed her eyes for a second and felt his lips over hers.

She had an old short and one of his shirts on, he offered her a few days before and she ended up enjoying sleeping wearing something with his scent. She kissed him back, giving in completely.
