47. National City 2047

Lian Yu.

The hellish island that his father spent years on was also the place that changed his father's life forever. The place where he lost his mom, that made him have nightmares as a child. Now he was back on it, as an adult. He didn't fear it anymore, he wasn't scared anymore.

As he walked by, he started to think about his life, about everything that has led him to this moment. He remembered looking for answers and finding only a clue that led him to that place. He saw a shadow from the distance while he tried to look around and think about where to start.

- Who the hell are you? – A guy wearing an old red hoodie said, aiming an arrow towards him.

- Wait a minute… - William said getting a bit closer and taking a proper look at his face – I know you…

- WHO ARE YOU? – The guy yelled.

- William Queen.

The guys lowered his weapon and looked surprised at him, taking his hood off.

- You're Oliver Queen's son?

- Yes. And you're Roy Harper, his old friend…

Roy looked serious at him, not quite believing what he was seeing.

- What the hell are you doing here?

- I'm looking for Kara…

- Kara?

- Kara Danvers…

- Kara… Supergirl? – Roy asked feeling a bit confused. – What would she be doing here?

- She vanished a few years ago and I recently got a clue about her… It led me here. I have this map, sort of, with me… But I have no idea where to start.

William gave him a paper and Roy looked at it. He gave William a brief smile.

- I know where to look… Follow me.

Roy and William walked until they reached the remaining of a plane that crashed there many years ago.

- This is the place Oliver used to hide when he was there. He told me to use if I ever needed it.

Roy looked around, with the help of William, trying to find something that could give them any clues about Kara. William looked at the corner, on the floor, and suddenly saw something weird underneath the leaf.

- Look at this! – He said as he grabbed the object. He had no idea what that was but it had a kryptonian symbol, so he knew he was on the right track.

- I think I recognize this… It's a key…

Roy held it with his both hands and turned the bottom to the left and the top of it to the right. The symbols lightened up and a hologram appeared.

- This is a message… But I don't understand a thing of it… - Roy said as he looked closer – Oliver showed me this once, but told me it was nothing I needed to worry about.

- I can read this! – William said – Kara taught me a bit of kryptonian, before I had to go live with my grandparents… It says that now I found the key, it's time to go back to National City and that I am ready.

- For what?

- It doesn't say.

- So we'll have to find out. Let's go back to National City!

.

William and Roy visited a lot of familiar places in National City, trying to find any clues or something that could give them any information. They were now at an empty CatCo, looking through James docs.

- Nothing here as well… I don't know where else we can look. – Roy commented looking around feeling lost.

- I know one more place we can look! – William said thinking for a while. – The old DEO. Kara told me about the place that looked like a cave; they used to work from there.

Roy followed William to the place. It was far away but it was the only place left to look. The place was really like a cave and it seemed abandoned. It had plants all over and old equipment's. Roy wondered what happened there. He has been away for so long and the last time he visited his friends, when William was just a kid, Kara lived in another Earth. He had no idea what happened, and how everyone lived in the same universe now, he also wanted to find out how Oliver died and how Kara disappeared. At least, he thought Oliver died, he had yet to confirm with William.

They walked around the place, William tried to make the big old computer work, but it was so old, he wasn't sure he was going to make it.

- Do you think there's any information about Kara there? – Roy looked curious, walking a bit closer.

- I guess so. She used to work here with the DEO. If only I can make this thing work, we can find out.

Suddenly, something hit the computer and made it explode. William and Roy jumped and turned to their side just to see a blonde woman wearing jeans, a grey shirt and a black jacket with glowing red eyes staring at them.

- Who are you? – She asked with a serious voice. – And why are you looking for information about Kara?

- You have heat vision… - William commented in shock.

- Who are you? I won't ask again! – She said taking one step closer.

- I'm William. She used to date my dad… Who are you?

- It doesn't… - She was going to send him off but stopped abruptly.

It was not possible, she thought. She looked curiously at William, taking another step closer to him.

- Are you Oliver Queen's son?

- Yes…

- And him… - She looked at Roy.

- I was his friend, part of Team Arrow…

- I'm Mia Danvers… Their daughter!

William and Roy looked shocked at Mia. William knew the basics about kryptonians, but he was sure they couldn't have kids with humans, so how on Earth he had a half-sister? he asked himself.

- I'm sorry but…. How…This is…

- Impossible? – Mia smiled. – Well, it's not impossible. – Her eyes came back to normal and she walked closer to the computer – Mom said she escaped for Earth 1, before Crisis…

- Crisis? – Roy asked – What crisis?

- Have you been lost on an island or something? How's possible you don't know about the crisis?

- I have pretty much have been living on an island… - He said – So no, I know nothing about it.

Mia rolled her eyes scratching her head. She looked at the two of them.

- My mom lived on another Earth, when we still had the multiverse. They went to Earth 1 so they could get a secret wedding because Agent of Liberty had been elected president on Earth 38 and it was dangerous for mom to be there. Then, crisis happened, the multiverse was gone and every Earth merged into one. This one we live in. There was a huge explosion…

- Oh, I remember an explosion, but I never realized what was going on. I never visited another Earth so I have no idea what it was like before… - William said remembering something about it, but feeling extremely surprised that was the reason that huge explosion happened back in the day. – But… What happened after?

- You're Oliver Queen's son, how can you not know about this? – Mia asked, still perplexed with William.

- I was sent to live with my grandparents. I never went back home, so I don't know what happened because my grandparents sent me to a school abroad, because it was dangerous for me to live in Central City and I couldn't go back to Star City.

William had tears in his eyes as he remembered being forced to grow up without his dad or anyone he knew in his life. Mia approached him, putting her hand on his shoulder.

- I'm sorry… - She said – Dad died in crisis. He sacrificed himself to save Barry Allen and mom, and she was really sad. The country had a new law anti-alien so she had to hide in Argo City. I was born there. When I was about 8 years old, she told me about everything. I told her I wanted to come to Earth and learn more about my dad and his family. When I got here, I got my powers thanks to the yellow Sun, and I was scared of being found, so I hid here. I looked around, found a few things about dad and the Danvers as well…

- Wow… - Roy said also shocked about all that Mia told them. He had no idea this all happened while he was gone and he wished he could have been around, before his friend died.

- I wish I could do something to change it all… So… Dad's really dead?

- Yes… I never got to meet him – She said looking at William with sadness. – But… I have been searching and I think I found a way…

- A way of what? – Roy asked, afraid of the answer.

- A way of going back in time…

- Are you crazy? When dad was alive, he told me that Flash did a real mess when he got back in time to save his mom; it changed things in the present…

- I don't care! – She said crossing her arms and looking serious at him – I need to see him, maybe help him save the future! We don't need to live like this, in this crappy judgmental world. We need to go to Central City!

William had no idea what to say. Mia looked determined and he had a feeling nothing would change her mind. Mia grabbed the both of them and used her super speed to get to Central City. She stopped when they reached Star Labs and William let go of her, feeling nauseous. Roy was already throwing up on the floor and Mia laughed.

- Sorry about that, I'm in a hurry!

Mia walked in, being followed by Roy and William. She looked around, using her x ray vision to make sure there were no unwanted visitors there.

- Are you ready? – A voice came from behind them and the three of them turned around.

- I have been ready for months, Nora Allen! – Mia smiled, hugging her. – We have company. This is my half-brother William and Oliver's friend, Roy.

- Nice to meet you.

- Are you Barry's daughter? – William asked, feeling overwhelmed with so many surprises.

- Yes.

- So… What's the plan here? – Roy asked.

- You'll see. – Mia said and smiled at Nora.

Nora held William and Mia held Roy with one hand and Nora with the other. With their combined speed, they opened a breach and traveled back in time. There were no more extrapolators around, so they had to improvise.

Once Nora and Mia stopped, with William and Roy by their side, it looked like the world was collapsing with people running everywhere, explosions happening, and huge fights. Mia looked terrorized at the scene.

- This is it… They day the crisis happened… - She looked around, trying to keep her focus.

She closed her eyes and tried to listen. All that noise gave her headache, but she learned to control her super hearing over the years. It almost drove her nuts, but she managed it. She heard from the distance a voice and she knew immediately who that was.

- We meet here later, I got to go! – She said and flew away.

Nora, William and Roy looked to their side just to see Barry Allen approaching the big fight. Nora ran towards him, with the others following her.

- Who are you – Barry asked and the, he looked surprised – Roy? What are you doing here?

- Hi Barry! – Roy waved at him and Nora interrupted.

- You can't go that way!

- Why not? They need my help; I will fight to protect this Earth!

- You don't understand, I…

- Sorry kid, I have to go… Whoever you are… - He said running fast, not even caring the fact that Roy exposed him to two completely strangers.

Nora nodded to Roy and William and went after Barry.

- I guess I will look for my father… Meet you here later. – William said

- Ok. I will try to help around here – Roy held his red bow, running towards the mess that was happening around them.

Mia flew around the city, trying to use her x ray vision to find the source of the voice she heard. Her heart was beating fast inside her chest and she kept imagining how it was going to be like seeing her dad for the first time in her life. She noticed Oliver was there, near a big crater on the ground, fighting a guy she recognized as the Anti-Monitor from the history books.

That was it.

The moment her father died, sacrificing himself for her mom and one of his best friends.

Not today, she thought.

She flew in the direction of that weird looking alien, her fists in front of her, and a determined look in her face. She couldn't think about anything else, but it looked like he anticipated her move. He turned around just in time to punch her and make her fall to the ground.

Mia looked at him feeling her veins on fire. She ignored the pain she felt and flew back, trying to punch him a second time. This time, she succeeded just before he could kill her dad for good. Anti – Monitor was thrown far away and she steeped in front of Oliver, looking viciously at the alien.

- Hi! – She said, smiling and going to him, throwing punch after punch.

He tried to avoid her but she used her freeze breath on his feet.

- You won't kill them today! I suggest you go to another universe!

- You can't stop what's coming. I'm just making things easier…

- I know I can't stop it. But I can stop you!

Mia used her heat vision on him. She felt a presence on her side.

- I got your back, sis! – William said as he stood by her, even without powers or anything.

Green Arrow stood at Mia's left side and pointed his arrow towards him.

- You have failed this Earth! – He shouted, shooting the arrow on the alien's shoulder.

Anti – Monitor screamed and the arrow got stuck in his skin and he couldn't get his of it. He felt his body on fire, like his veins were burning up.

- It is coming… You can't stop it! – He said, vanishing from the air.

A big explosion happened and the ground trembled. Mia looked at Kara and Oliver and then around her, frightened.

- This is it… - She murmured.

- What just happened? And who are you? – Oliver looked confused and scared for the first time in years.

- Hi… - Mia waved at Oliver, not finding the right words to say as her heart almost jumped from her chest.

Meanwhile, Nora followed Barry, managing to stop him from going where Oliver and Kara were fighting Anti-Monitor. Barry looked pissed and really annoyed. His face was covered in worry and he started freaking out.

- If anything happens to them…

- Nothing will! – Nora says – Not this time…

- What are you talking about? How do you know?

- I'm from the future… I'm your daughter!

Barry looked shocked as he stopped walking from one side to another. He couldn't believe he actually heard what he just heard.

- You're what?

- Your daughter from the future! I couldn't let you go there because this is when you disappear. When you help Oliver and Kara fight that alien, Oliver dies and you disappear.

- Oliver? What? I'm…

- I know, it's too much… But trust me, you not being there is huge.

- I'm supposed to let my friend die so I can save myself?

- No, he's not going to die anymore… His daughter from the future is there, saving him and her mom. Trust me. William's also there…

- William? – Barry looked even more lost than he already was - You guys have some sort of club of super kids in the future? I'm… This is too much… Oliver's daughter… Wow!

- The important thing is that you all are safe now! But…

- But what?

- The multiverse is gone… This explosion…

- All Earths collided?

- Yes.

- I dreamed about this a few weeks ago… - Barry looked to the ground, not quite understanding what just happened. His head was pure confusion and he needed to take a break to process it all.

Mia collapsed on the ground after saying hi to her dad finally. William moved quickly and caught her before she could hit the ground.

- I'm your son, William, from the future… And she's your daughter with Kara… We can explain everything, but we need to take her to Star Labs first.

Oliver just heard that and nodded with his head, not being able to process all that information in only a few seconds.

Barry, Iris, Oliver, Ralph and Diggle were at Star Labs, waiting for news. Nora and William stood side by side, also waiting nervously.

- She's stable now… Roy is still out, but he is recovered from his head injury. You brought him just in time - Caitlin said coming from the med bay and looking at Nora. – But… What just happened? They're your kids from the future? – She pointed at Oliver, Iris, Kara and Barry.

- Apparently… - Iris said, looking as shocked as Barry.

- William? – Oliver looked at his son all grown up – This is so weird, the last time I saw you, you were just a kid…

- I know… But I'm here now! – He smiled.

Mia came running from the med bay and Caitlin tried to calm her. She was not expecting Mia to practically jump desperate from her bed.

- You need to rest.

- What I need is to see Kara! Where is she?

- She's coming. She was patrolling the skies before – Barry said. – She came from Argo to help us.

Kara arrived, still in her Supergirl suit. She looked at everyone.

- Our apartment is here on this Earth, and also CatCo… It's all so confusing…

- Mom! – Mia ran towards Kara, hugging her strongly and almost knocking her down.

- Hi…? – Kara said looking confused at the others.

- She's our daughter from the future… - Oliver said and Mia ran towards him, hugging him too.

- Oh… - Kara said, looking at Mia not knowing exactly what to say.

- I thought I would never see you…

- What do you mean? – Barry asked.

Mia let go of her father and wiped her tears away. She looked at them all. William tried to tell her they couldn't say anything but Mia interrupted him before he could speak.

- They need to know why we are here! And we need a few answers too! – She turned to Oliver and Kara. – In the original timeline you died to save Barry and mom. After that, they created an anti-alien law so mom had to run to Argo City. I was born there.

- And I never came back home… - William said, giving up of hiding things from them. They needed to know and he also needed to know why his dad let his grandparents send him away. – I just wanted to know why you let them take me away…

- William… - Oliver took a few steps closer to him, reaching for his shoulders – Believe me, I didn't want to. I fought your grandparents so they wouldn't send you away, but I lost the fight… They got a restraint order, I couldn't go closer to you ever again. The judge said I was dangerous and had a lot of enemies that could put you in danger…

- They did that?

- Yes.

- All this time… I thought you abandoned me… - William said as he looked at his dad, finally being able to properly look into his eyes.

- I would never do that!

Oliver and William hugged. Finally, he felt like he could move on with his life and he had a feeling things would be totally different in his future.

- And you vanished on this crisis – Nora said, turning to Barry with tears in her eyes – I grew up with only stories about you being the Flash. I know is dangerous to change the past, mom always told me that – She smiled at Iris – But I couldn't just let you vanish.

- It's ok… - Barry hugged Nora and Iris at the same time. – Thank you for saving me, for helping save all of us.

- And if it's ok with you, we would like to stay for the rest of the day… I have so many questions… - Mia said as she looked to her parents. She couldn't miss the opportunity.

- Its ok, I think I have a few questions too… - Kara smiled.

At the Queen's apartment in National City, Mia, William, Kara and Oliver sat beside each other on their huge couch. Mia tried to fill her parents with some bits of information but tried not to reveal much.

- I can't tell you exactly what happened, but… You brought dad to a special trip… - Mia said blushing hard.

Kara laughed understanding what she was saying. She looked at Oliver lovingly.

- Argo City… There's red sun there so…

- Ok, got it! Please, don't share anything else, thank you – William said smiling at Mia and Kara. He looked at his dad – I think things will be better now. We changed that horrible future.

- I hope so… And I hope that law never passes… - Kara said – I can't imagine having to leave you… - She said, holding Oliver's hand.

The next morning came and they all gathered in Star Labs to say their goodbyes. Roy scratched his head, still feeling a bit of a pain.

- Take some rest when you go back, you were hurt pretty bad. – Caitlin said.

- Thank you…

- It's great to see you with grey hair and all – Oliver said smiling at Roy – Thanks for the help. You almost sacrificed yourself to help us, I won't forget this…

- You did a lot for me in the past, man. I would help you again without thinking twice. – They hugged and Roy stepped away.

Nora hugged Iris and Barry while Mia and William hugged Kara and Oliver.

- I guess it's time… - Nora said holding Roy with her.

Mia hugged William and looked emotionally to her parents. Oliver, Kara, Barry, Iris and Caitlin watched them disappear back to the future.

The week passed by and they started feeling the changes around their world. It was weird living on the same Earth but at the same time it was a relief. The government tried to pass the anti-alien law, but failed and all aliens around the world celebrated. Kara and Oliver were at their apartment celebrating privately.

- I'm so glad you won't ever have to hide or run away… - Oliver said, hugging Kara as they lay in bed. Red light reflected on their skin and Kara smiled at Oliver.

- Do you think Caitlin will miss the Red Sun lamps we took from Star Labs? – She laughed

- We will give them back later… - He smiled, kissing her – I want to meet Mia in the future.

- Me too.

.

NOTES:

Spoiler alert: Red daughter gets caught on Kara's place and gets called to help our heroes. Things will get messy, fun and romatic at the same time.
