.

17. World's Finest

The Green Arrow patrolled Star City as he did every single night. Diggle was giving him back up while Felicity was on the bunker, helping them as she hacked security cameras and warned them if there was any danger. It was just the three of them, just like good old times. Oliver was focusing on their target as the person just vanished, appearing again behind Oliver. Diggle shoot him before he could do anything, but the guy was quick enough to deflect it.

- How is he… - Diggle said as he looked horrified at the guy vanishing and appearing again. He was feeling dizzy.

- No idea! This is Barry' specialty! – Oliver said as he aimed an arrow towards the mysterious guy, but it was useless…

- I think he is a breacher… - Felicity said as she tried to think about it.

- A what? – Diggle said feeling even more confused than before.

- The same as Cisco… He can open breaches and travel through them.

- Felicity, please call Barry…

- I already did that. He said he will come soon, he is dealing with a lunatic in Central City, and they are going after him as we speak. Then, he will come over.

Oliver thought about his lack of luck but accepted just fine. His friend had his own craziness to deal with, so he would have to improvise for now. The only problem was that the guy kept vanishing and appearing again, making it difficult for Oliver to actually hit him.

- You need to relax, greenie! – The guy said laughing as a maniac – And I have the perfect place for you… - He said as he vanished again, reappearing behind Oliver and pushing him towards a breach.

- HEY!

There was no time for Oliver to do anything. He heard Diggle and Felicity yelling his name on his comms as the thing just went off and he took it from his ear. He felt something weird like he was falling, then he literally dropped on the ground, trying to get up. He looked around just to see the middle of nowhere.

- Where the hell am I? – He wondered as he looked at his comms on his hands, useless now.

A strong wind came in his direction, making him fall again; he looked up at the sky and rubbed his eyes to make sure he was seeing what he thought he just saw.

A woman was flying high on the sky and really fast. She came in landing abruptly and rolled on the ground before stopping. Oliver walked towards her, feeling worried. He was still processing the fact that she could fly, but he was a gentleman. He needed to see if she was ok.

He approached her and noticed her blonde wavy hair all around her face. She opened her eyes and looked confused, one of her hands on her ear, it looked like she was having trouble hearing well. She had deep blue eyes, the most beautiful eyes he had ever seen.

She was really beautiful, he thought as he looked cautiously at her. She was dressed like a hero, but he had no idea who she was. It made him wonder where the hell that weirdo sent him.

- Are you ok? – He asked, looking worried at her.

- Yes… I guess… I… - She looked around feeling a bit confused. She had no idea who the hell that funny guy wearing a funny suit was, but she needed to go back to CatCo.

Kara prepared to take flight once more, but Oliver was fast enough to use one of his tricky arrows to shoot wires around her feet, trying to pull her back to the ground.

He had questions. He needed answers.

Apparently she was not just able to fly, but also super strong because she flew anyways, with Oliver holding strongly the end of the wire. Kara looked down and found that really weird. She needed some answers.

She went back to the ground, dropping Oliver first before landing.

- I'm sorry… - She said as she looked confused at him. – Excuse me but… Who are you?

- I'm guessing you never heard of the Green Arrow…

- Should I?

- Well…

Oliver looked at her, really worried now. He must be really far away.

- Who are you? – Oliver asked

- I'm Supergirl… - She answered him like he was being a fool asking it, since he should know who she was, at least it sounded like that.

- Who now?

- You also don't know who I am?

- No… - He looked around and scratched his head.

Oliver remembered Barry describing when he visited Earth 2 once and it hit him.

- I am on the wrong Earth…

- What?

Kara looked at him having no idea what he was talking about. She noticed the worried look on his face and by the way he was dressed and acted, with that nickname, he must be some sort of super hero… But she was confused. He was a human, no powers apparently. How on Earth was he a hero?

Kara took him to CatCo, and once there, both in regular clothing again, she took him to a quiet room as he asked to use the computer and do some research.

- There's a Star City here… - He looked at the computer – And apparently I died here. I think is not a good idea for me to walk around then… - He was murmuring to himself, making Kara feel way more confused.

- Wait… What do you mean, another Earth? We are on Earth…This one!

- Barry is so much better at this than I am… But I'll try anyways… - He turned the chair around, looking at her in her cute yellow dress and glasses. She was really cute, it was hard to concentrate, he thought. – I am a vigilante on my Earth, I was fighting some lunatic that open breaches and he threw me here. Where is here anyways?

- National City!

- I think we have one back there…

Oliver was about to explain more when the door opened. Two guys came in, smiling at Kara and one of them stopped abruptly, seeing him there.

- Kara? It's everything ok? – The taller guy asked.

- Hi James, and Winn… - Kara smiled so brightly it could blind them inside that room. Oliver wondered if any of them was her boyfriend or something. – Yes, everything is just fine. I want to introduce you to Oliver…

- Hey I know you… - Winn said as he shook hands with Oliver.

- No, you don't! – Oliver looked serious at Winn, scaring him a little bit.

- You are right… - James looked at Winn and then at Oliver – Weren't you dead or something?

- Ok, I don't know how to explain this… I mean, I do it's just…

- Kara! – Winn and James said at the same time.

- He is from another universe! – Kara smiled, her hands pointing at Oliver.

- Another universe? – James looked at Kara, finding that hard to believe.

- The multiverse theory is real? – Winn looked excitedly at Oliver. He was really happy out of sudden to hear Oliver.

- Yes, according to my speedster friend.

- You have a friend that is a speedster? Oh my God, I want to visit your world! – Winn said as he smiled at them.

- Oliver is a vigilante in his Earth. He was thrown here by some lunatic, and he needs help to go back home… - Kara explained as she adjusted her glasses. She turned to Oliver, looking at him. – We will help you get back home, don't worry…

- I can help trying to create something to help you open a breach back home… It just might take a while…

- Its ok, any help is welcome!

Kara smiled looking at Oliver. She was full of curiosity, wanting to ask him hundreds of questions. She never met anyone from another universe before; she didn't even know it was a real thing until today. She was curious especially about the fact that Oliver was a hero being only human. He looked like someone who had a lot of stories to tell. Something inside Kara made her really excited to hear them.

- One thing you are right, it's not wise for you to be seen outside. Oliver Queen from this Earth is dead and people can be suspicious… - Kara said as she turned to the others. – Oliver can stay with me for now. If it is ok with you.

Oliver looked surprised at Kara. She barely knew him and was willing to help and hide him. She seemed like someone really good that loved helping people. And she seemed to really love it; she looked like a kid who won her favorite candy. One more thing he thought it was cute about her.

- It is ok as long as I don't create any trouble for you…

- Oh, no problem at all… - Kara smirked at him and James kept looking at them, not really liking where that was going. She looked around and smiled – Here – She reached for a baseball cap that was on the room and gave it to Oliver – Just in case…

Winn just tried to hold his laughter as he looked at James. He was clearly jealous. James was a great friend, but it was nice for a change to see someone going through what he went through a few months ago, he thought.

- Well, you have the right person to help you then… - Winn said as he smiled at Kara – nothing better than a powerful alien to help you get home, my friend.

- Alien? - Oliver looked at Kara. Now he was truly surprised… And shocked…

- Yes. I am from a planet named Krypton. It exploded when I was a kid and before it, my parents sent me here along with my cousin…

- Wow… That's cool! – Oliver kept looking surprised at everyone.

That explained the flying, the super strength and God know what else, he thought. Usually, he would be cautious and hold back, it was not easy for him to trust people, even more people from another Earth, but something inside him told him that Kara was someone he could trust. He would have to check that, but he had a good feeling about her.

- While Winn work with this, we can go and grab something to eat… I'm starving – Kara said bluntly and James arched an eyebrow towards her. He was the one who decided not to be with Kara, since his break up with Lucy was way too recent, but he couldn't help feeling bothered by the fact that Kara just asked another guy out right in front of him. – I need a lot of food…

- That's ok – Oliver smiled

- I also have so many questions… - She smiled as they started to leave

- So do I – He said as he looked around CatCo.

It was a nice place to work, he thought. At least it looked like it. He heard the voice of a woman calling Kara by a weird name and followed as Kara rushed towards her.

- Yes, miss Grant?

- Keirah, I need you to not speak to anyone about that crazy bitch attack on you, ok?

- Attack? – Oliver asked feeling curious

- An ex-employee of mine it's in desperate need of attention and attacked Keirah, and who the hell are you?

- I'm… - Oliver started but was interrupted by Kara.

- He is a friend from out of town… - Kara smiled awkwardly from Oliver to the Grant woman.

- I also hear rumors about a new vigilante in town. Some people saw a green hooded figure wondering around… I need a scoop…and a name…You stranger can go, I need to talk to my assistant!

Oliver just turned around and walked out, deciding to wait for Kara near the elevator. That was a very rude woman and he wondered how on Earth Kara managed to keep up with her.

Kara approached Cat Grant's table and waited for her to say what she wanted. Cat just looked at Kara with a weird smile.

- You just keep impressing me, Kierah!

- Me? Why? – Kara looked confused at her boss.

- James was a waste of time anyway, don't get me wrong, but this guy with you, it's really an improvement.

- Who? O… Him? – Kara almost told his name to Cat Grant. – No, no…it's nothing like that.

- Keirah! – Cat got up from her chair and took her glasses off her face. – Please. The way he looks at you says it all, and the way you two entered my office like two teenagers in love… I mean… You should go for it. James is the one who lost, and you deserve to be happy. Now get out of my office and please, find that scoop on that green vigilante. I'll think about a name for him later.

Kara walked out of Cat Grant's office and found Oliver waiting for her. Kara adjusted her glasses, whispering to Oliver, still blushing over her conversation with her boss.

- I think people saw when we stopped that thief next to the bank…

- Yes, they saw me! But it's ok.

- Miss Grant won't rest until she gets a scoop on you.

- Let her be. She looks like she needs to occupy her mind for a while.

Kara received a call from J'onn at the DEO and brought Winn and Oliver there with her. She introduced him to everyone, telling them he was a hero from another universe. It was not an easy thing to tell people, but she was an alien herself, so it was ok.

- We need to act now! Livewire escaped and it's creating havoc out there. – Lucy said as she looked worried towards Kara. – And she is working with street criminals…

- It can be a distraction… - J'onn said

- I can help!

Everyone looked at Oliver, half intrigued half excited. J'onn was the only one serious as he approached Oliver, with his arms crossed.

- And how could you help us? You are human!

- I have experience on dealing with street criminals. I do it all the time in my city.

- I don't know… - Lucy scratched her head.

- I trained a speedster and gave him a really hard time and I also took down a extremely dangerous 300 years old guy, head of a group called league of assassins, I think I can handle a few street criminals!

Kara looked at Oliver feeling way more curious about him than she was before. She was really excited to have him there with them, helping, so she was the first to agree.

- Yes, Oliver can help us! – She smiled at him and looked at the others – He told me he has been doing this for years now. We can trust him! Winn it's still working on the device to help him go back to his world, so for now… Why not?

J'onn finally agreed and Kara smiled excitedly at Oliver. He suited up, grabbed his equipment and went out to where those criminals were attacking. If there was one thing Oliver really hated was when people doubted him or his skills. To be fair those people didn't know him and lived really far away, they were used to deal with aliens, monsters, people with powers, so he wasn't that pissed. Supergirl flew away to deal with Livewire and J'onn, Lucy and Winn kept hearing everything from their comms.

- Drop the gun now! – They heard Oliver shouting.

- Or what? – The guy asked him.

Next, they heard a yell of pain. A few more noises and Oliver tapped his comms again to report his situation.

- The three guys are taken care of; I suggest you call the cops. Also, they will need a hospital!

- What? – J'onn asked as he looked scared at Lucy.

- They tried to hurt me, I was faster!

- Oliver…

- They are alive! And won't hurt anyone. That's what matters.

Lucy looked at J'onn with a mix of surprise and scare on her face.

- Well, he took care of them pretty quickly…

- Miss Lane! – J'onn looked at her in a reproving way and walked away.

Supergirl had a bit more of difficulty dealing with Livewire, but nothing she couldn't handle. The woman was once again locked in a cell inside the DEO. Kara walked to the balcony of the DEO and found Oliver there, looking at the city.

- People say you terrified J'onn… This is not an easy thing to do – Kara teased him as she stood beside him, also looking at the city.

- I have my own methods of dealing with bad guys… Not everyone likes it.

- Have you ever dealt with people in general, not trusting you? Like no matter what you do for them, they see you as a threat, as someone who is not reliable?

Oliver looked at Kara with a questioning look. God, he knew that feeling way too much. He remembered all the times he did his best to save the city and still, was considered someone dangerous.

- I'm asking because I am dealing with this right now and I'm kind of lost… I tried everything…

- People don't trust you? How?

- A few weeks ago, let's just say I wasn't myself. I was affected by something and it brought out the worst in me. Terrible things happened and now people hate Supergirl. To do this, save the city, save people… It means everything to me. When I am out there, saving the world… It's the best thing ever, there's nothing like it. It used to mean something and now it means distrust, fear…

Oliver didn't know Kara that well but he could see she was passionate about what she did. She had amazing powers and used that to save others. She was selfless as he could see these brief hours they spent together, and willing to do everything to help other people. This was so rare to find out there, he thought.

- Well… Answering your question… Yes. And more than I wished for… It's not easy, I confess.

- What happened?

- When I started… I was a killer. I killed bad guys; I used to torture them, because I thought there was no other way for me to do it. The city was dying; it was an ugly place to live. Drugs, powerful and rich people controlling everything. I had to fight back the best way I knew how. This made the cops go after me as if I was a criminal. In many eyes, I was one, because there is no excuse for killing… - He looked into Kara's eyes seeing she was fully paying attention to his words, sinking in what he was telling her and by the look in her eyes, she was understanding him, in a way… - After losing my best friend in a terrible attack on my city, I decided to change the way I did things. I stopped killing. I did all in my power to help the cops catch the bad guys, to protect people. Until today, there are a lot of people who don't trust the Green Arrow. They think vigilantes doesn't help, they make things worse.

- This is not true! – Kara said as she adjusted her glasses and looked at Oliver – You live in a city where people need protection. You have your way of dealing with them, but you are helping them… People should see that!

- But some don't. And it's ok. I never did it for rewards or recognition. I do what I have to do even if people hate me sometimes… The thing is… - He took a step closer to Kara. – Don't try it so hard. Just give them time. Slowly, they will see they are being unfair. It's understandable their fear, but they will come around. It's all about baby steps. There's always a way to fix what was broken, you just need patience.

Patience was not the strongest thing about Kara; she knew it was a huge problem. But Oliver had a point. She couldn't keep forcing things for people to forgive her like this.

- You know, you right… - She said as she couldn't keep her eyes off of him – I was so used to people loving Supergirl that I couldn't even sleep properly because I was worried, I wanted them to forgive her and love her…

- You're doing your best and people will eventually see it. I just met you, and I can see it.

Oliver never met anyone like Kara. He couldn't trust his own shadow on his Earth, but meeting her, changed a few perspectives to him. She was losing her sleep, worrying about people hating her, trying her best and going beyond anything just to gain their trust and help them. She really loved her city, her people; he could see it better now. There was this fire and passion when she talked about saving the world, he never saw it in anyone before.

- I know it sucks you are stuck here for now… But I am glad you are here…

- Me too – Oliver said as he took one step closer to Kara, her face inches from his.

Maybe Cat Grant was right. Maybe meeting Oliver was meant to be. He was a hero just like her, and ok, he lived far away, but… She couldn't help but feeling a special connection between them. Oliver's hand reached for Kara's cheek as he approached his lips from hers, barely touching it. He thought about how he felt miserable before, having to always lie to people, hide who he really was and that was the reason he couldn't find anyone to be with. And now, there was this beautiful woman right in front of him, with similar issues and the same life he lived. Except she was an alien, but for him, this was just a detail. By heart, she was more human than many humans he knew. He could feel her breath closer to him lips when her cell phone rang loudly, waking them up from their trance.

- I'm sorry, I… - Oliver said as he took two steps back.

- It's ok – Kara smiled as she picked up. It was Winn.

She talked to him, feeling her cheeks burning and her heart racing. She just had a moment with Oliver and Rao knows what would have happened if Winn hadn't call her but deep down, she was a bit sad they were interrupted.

- Winn said the device will be ready by tomorrow – She gave him a weak smile.

- Good… - Oliver said, still feeling his heart almost jumping from his chest.

- Want to grab that lunch? We can eat in my place…

- That's perfect – Oliver said and followed Kara.

They grabbed food from a restaurant nearby and went to Kara's apartment. Oliver felt really comfortable once there, it was so different than the places he had been on his Star City. That city looked a bit brighter, people seemed nicer… It was really weird.

Oliver was surprised to see that Kara ate a lot of food. Way more than Barry ate, and it was something he thought it was impossible. After they finished, they sat on her couch and Kara turned to face Oliver as they sat inches apart. She felt comfortable for the first time in a long time. She noticed the look in his eyes, they knee almost touching and her hands resting on her lap.

- I'm curious… - He started – What else can you do? Besides flying and being super-fast and super strong?

- Well… I have heat vision…

- Like… You can heat things with your eyes?

- Like this… - She grabbed a cup of tea from the kitchen and brought him, staring as the tea and heating it up with her eyes.

Oliver saw a red strike of light coming from Kara's eyes and looked at her in awe. This was really something else.

- Wow… I bet this is useful…

- Yes, especially when my food it's cold. – She joked, making Oliver laugh. She looked at him noticing what a beautiful smile he had, but she noticed he didn't smile a lot. – I also have x ray vision…

- You can see through things?

- Yes. And I have freeze breath, super hearing, telescopic vision, electromagnetic spectrum vision, infrared vision, microscopic vision and I'm invulnerable.

- I'm officially impressed – Oliver smiled as he looked Kara blushing.

- You are the one who's impressive mister. I was really surprised when they told me you handled three guys by yourself and really fast… How this happened by the way? Your vigilante life?

- It's not a colorful story…

- Mine's not as well. C'mon, I really want to know… - She reached for his hand and held it slightly. Oliver looked at their hands and showed a brief smile on his face. He looked back at her, his hand still on hers.

- I don't want to scare you… I never talk about this with anyone…

- I don't scare that easily… - She reassured him with her eyes it was ok to tell her, she could handle it.

- Well…

Oliver started to tell his story with some difficulty. No one in his life heard the entire thing, all the details. He wasn't sure about telling everything to Kara but once again, there was that familiar feeling of comfort and trust, something he was not used to.

- You had an accident?

- Yes. And I spent five years away with everyone thinking I had died. I was a shitty person before it but everything I have been through made me become someone else… And I had to do horrible things to survive and come back home…

- The shitty person, I agree with. Not cool to go away with your girlfriend's sister. But I am glad to know you used your bad experiences to become someone better…

- I don't know if a killer is better than a cheater…

- You said yourself you changed… Everyone deserves another chance. You got yours and you learned… This is what matters.

- Nobody has ever told me things about this perspective.

- I believe everyone has light and darkness inside them. And sometimes in life they think darkness is the only way, but as long as their good side can be reached and they can try a different path, it's ok.

- How can you see things in such a positive way? People usually look scared at me when I reach only the surface of my past…

- I have to believe in a better world, with better people. I have to believe we can still reach the good in people, and most of them just need help. You suffered a tragic thing in your life, you could have turned into a dangerous criminal, and you could use your status and money on your Earth for a lot of bad things. You chose to help others. You started kind of wrong, but went to the right way afterwards… If we don't recognize the minimum of efforts, everything's lost. And I refuse to believe in a world where everything is lost, humanity can be better than this!

- Are you even real?

Kara looked at Oliver and blushed harder than before. They sat really close to each other and she could feel that vibe between them, the same she felt when they almost kissed. She felt like a school girl hanging out with her crush out of sudden.

- As far as I'm concerned, I am. – She laughed.

He couldn't believe someone like Kara existed. She was literally something else, someone unique. He could never be half optimistic as she was and have half the faith she had on people. And that was what made him attracted to her: her heart, her beautiful soul. He caressed her hand with his fingers, holding it and giving her a small pull, making her be really close to him. He looked into her eyes and felt his heart racing again.

- I never thought I would meet someone that had so many things in common with me… A human… - She whispered as she kept looking into his deep blue eyes, feeling like she was lost in them.

- It's nice to finally be able to talk about that with someone who truly understands for a change – He teased as she smirked at him.

- My thoughts exactly!

Oliver closed the space between them, reaching for her lips as she passionately responded to his kiss. One of his hands went to her cheek and the other to her waist, fully embracing her body with his.

Kara's heart felt like an uncontrollable drum being played. Oliver's lips felt amazing against hers, she could feel his strong arms around her and she opened her mouth a bit more, allowing his tongue to massage hers slowly.

- You are unique, Kara – he whispered between their kiss.

- I'm not…

- Yes, you are.

Oliver looked at her as they both took a few breaths.

- You have a heart that is hard to see on other people. I'm glad I met you.

- I'm glad too – She smiled as she reached for his collar, bringing him with her as she rested her back on the couch, lying down.

- I'm going home tomorrow… - He said as his body covered hers, caressing her cheeks.

- Let's not worry about tomorrow… We have tonight!

Kara reached for his lips this time around, giving him a slower kiss. His lips gave her small kisses towards her neck and she felt shivers down her spine. She held his chin and brought his lips back to hers; savoring every moment she had left with him. She rose up from the couch, making Oliver sit back as she took his shirt off of him and threw it far away. Her fingers touched his scars, caressing every single one of them.

- These marks… I can see how much you suffer by looking at them. They hurt. And look at you – She said as she looked into his eyes again – Sitting here with me in an Earth far away from yours, but alive and well. There's nothing wrong in surviving, Oliver.

- These are ugly marks.

- No, they are not! They are part of you, part of your story. They are part of what made you who you are today. It makes them beautiful.

Oliver crashed her lips as he heard her words, not being able to control himself anymore. She was definitely the most precious person he has ever met. No one would have looked at his scars like that, not being scared and seeing the beauty behind it, even if he didn't see it at all. He felt her hands caressing his torso as he kissed her with so much passion, something he never felt before on this scale.

Life was funny, he thought. The last thing he expected in his life was to end up in another Earth and fall in love with a sweet, beautiful and strong alien.

The next day, Kara brought Oliver to the DEO so Winn could give him his device to help him go back home.

- Remember Kara, you need to use your speed to help. Then, he presses this button and voilá!

- Ok, thank you so much Winn! – Kara said as she grabbed the device and looked at Oliver.

There was a kind of sadness on his face that mirrored hers. They knew this moment would come; they just didn't want to think about it until now.

Kara brought Oliver to the middle of nowhere, so there wouldn't be any questions or curious faces around.

- So… This is it…

- Yes – Kara said as she took one step closer to Oliver.

- Listen…about last night…

- I don't regret a thing… - She smiled at him, remembering the night they had. Rao, she would miss him.

- Neither do I. – He looked at the device in her hands as she gave it to him. – Things thing can allow me to visit? Maybe if… I ever want to?

Kara's smile was huge right now. She looked at him and nodded with her head.

- According to Winn, yes!

- Perfect! – Oliver took a step closer and kissed Kara one more time. It was a slow and deep passionate kiss this time. – I will miss you, girl of steel!

- I will miss you too, emerald archer!

One more kiss later and Kara prepared to run with Oliver in her arms.

- Ready? – She smiled, looking at him – One, two…

She ran really fast and Oliver pressed the button of the device. A breach opened and Kara pushed him through it, even if it was the last thing she wanted to do.

Oliver had vanished back to his Earth.

Kara looked down her feet.

- Bye Ollie!

NOTES:

SPOILER ALERT: Prompt from WritersBlock039: And I remember in "Where Are We Now" that Kara was jealous when Oliver was with Lena . . . maybe have Oliver be jealous/possessive when Kara's with James or Mon-El?
