Hey everyone, I know it's been a really long time, I'm really sorry about that. I hope you all are doing well.

This chapter was the next request that I had on my list and I decided to post it since I had already written most of it. But, since it's been so long and I'm not sure if the same people are still following the story, I figured I'd go ahead and just start writing any new prompts you guys send in instead of doing ones for people that may not be reading anymore.

That being said, if you sent me a prompt and I haven't written it yet, or if you have something you'd like to see, please feel free to let me know. I don't know if I'll be updating on a super regular basis, but I'll try as best as I can.

I hope you enjoy and thanks for reading. Let me know what you think.

Summarized Prompt: Kara gets kidnapped in 2x19 instead of Alex, and Alex has to save her. (I follow the plot of the show at some points, but I also diverge quite a bit to make it realistically fit for a one-shot.)

Alex paced through the DEO as she tried to calm her worry. Why wasn't Kara answering her phone?

She had been trying to reach Kara all morning, but she couldn't get a hold of her.

Kara wasn't at her apartment either, Alex had gone by to check, but no one was there.

Maybe Kara had gone flying, that wasn't uncommon for her to do.

But it wasn't usually for this long, Alex couldn't shake the feeling that something wasn't right.

She headed towards Winn's direction, thinking she would ask him if he had heard from Kara.

As she reached his desk, her phone rang, and the caller ID showed it was Kara.

"Thank goodness," Alex mumbled to herself as she answered, "Hey Kara, where have you been?"

"This isn't Kara."

Alex felt her stomach drop and her mouth go dry.

"Who is this?" she forced out, clinching her hand into a fist.

"Well that doesn't matter, what does matter is that I have your sister."

Alex squeezed her hand tighter, motioning to Winn, who had been watching the exchange with wide eyes, to start tracking her phone.

Finally, he got the message.

"You're lying," Alex said, partially because she thought he was, and partially because she was trying to buy more time for Winn to track the call.

Suddenly her phone buzzed, and she looked down to see a picture of Kara tied up.

Blood poured down the side of her head and across her face, but Alex could see her sister's bright blue eyes open, staring in defiance at whoever had taken the photo.

This couldn't be happening; how could someone kidnap the girl of steel?

Alex scanned the photo until her eyes caught what she was looking for, the familiar glow of kryptonite coming from a source somewhere out of the picture.

Whoever this was, they knew Kara's secret.

Hands shaking, Alex put the phone back up to her ear, "What do you want?"

Alex looked at Winn, who gestured that he hadn't tracked the call yet.

"A man named Peter Thompson is serving a life sentence at Albatross Bay Supermax. You will free him within the next hours or your sister will die."

"How do you expect me to get a prisoner set free?" Alex responded as she gave up clinching her fist and instead twisted her fingers around the hem of her shirt.

"I think a DEO agent can figure it out."

Alex felt the panic start to grow even more, whoever this was, he knew about Kara and Alex.

"How do you know that? Who are you?" Alex said.

The only response was a click and then a buzz.

"Hello?" Alex tried, but she already knew he had hung up.

She took as deep of a breath as she could, which did nothing to calm her, and turned to Winn.

"Please tell me you were able to track that?" Alex asked.

"I- I tried but there wasn't enough time for me to complete it, I got nothing."

"So, this person who says they've kidnapped Kara, what exactly did they say on the call?" J'onn asked Alex as they all stood at the center of the DEO.

"He said he would kill Kara if I didn't break Peter Thompson out of Albatross Bay. He said he knows that she's Supergirl." Alex responded, running her hand through her hair.

Winn turned in his chair to face everyone, "This might be stating the obvious here, but why don't we just spring Peter Thompson and bring Kara home?" He said.

"The DEO does not negotiate with terrorists." J'onn answered, saying what Alex was already thinking.

"But this is Kara." Winn argued.

"If we do it once, we'll open the floodgates. Every bad guy will know Supergirl can be controlled. And even if we do what he wants, it doesn't guarantee he'll release her. She's his insurance." J'onn said.

Alex knew he was right, but she still hated to hear it.

J'onn took a deep breath, closing his eyes for a second as if he didn't like what he just had to say either.

"All right, people, let's get to work!" J'onn yelled.

Just like that, the place ignited into action as agents eagerly went to play their role in finding Supergirl.

"Let's start with what we do know. If this guy knows she's Supergirl, we use that to our advantage. That's gotta be a short list. Who knows her secret?" J'onn said to Alex.

"My mom, my dad, Clark, the DEO..." Alex said, gesturing to the agents rushing by.

That was a lot of people, but Alex had thought she could trust all of them.

But what if someone in this room was responsible?

J'onn, Winn, and Alex sat in silence for a moment before Winn spoke.

"I think we're asking the wrong question," He said.

Alex and J'onn waited for him to continue, but it didn't seem like he was planning on volunteering any more information.

"Winn," Alex said, trying to keep the agitation out of her voice, "What's the right one?"

Winn looked up and met her gaze, "Who is Peter Thompson, and what does he mean to the kidnapper?"

"Hey, I think we got something," Winn said to Alex over the phone.

Alex had just gotten through a completely useless interrogation with Peter Thompson, so getting some good news was a nice change of pace.

"What is it?" she said back, turning to J'onn as she spoke.

"So I ran the facial recognition program, and it turns out Thompson has a son," Winn said.

"But we checked for any family relations already," Alex responded.

"Well apparently there's a lot of family drama. I only figured this out after I cross-checked the name with the court transcripts. The kid spoke at Thompson's sentencing."

"Who is it?" Alex questioned as she drummed her fingers on the fabric of her pants leg.

"His name is Rick Malverne." Winn said.

Alex ran the name through her mind, it sounded familiar, but she wasn't sure.

"Why does that name sound so familiar?" She spoke out loud, half to her herself and half to Winn.

"Because he grew up in Midvale." Winn responded.

Alex carefully scanned each room as she moved through the building, looking for any signs of Kara. This was the last known location that was listed as Rick Malverne's address.

She turned the corner of a hallway and stopped short at the image in front of her. A computer screen sat on an empty table, on the screen there was what looked like computer footage of a large cell.

Inside the cell was Kara.

"Kara!" Alex yelled, rushing forward and grasping the screen. She didn't expect Kara to be able to hear her, but to her surprise her sister turned and looked at the camera.

"Alex is that you?" Kara said, standing to move so she was as close as she could be to the camera above her.

Alex didn't miss the way Kara stumbled as she stood, or the blood that was stained on her clothes.

"Yeah it's me Kara, where are you?" Alex asked, trying to keep her voice steady as it broke with emotion.

"I don't know, but I'm powerless. He had kryptonite and I couldn't-"

Then the screen went black.

"Kara?" Alex yelled, shaking the screen in a futile attempt to get the image back.

"Agent Danvers, we found him." Someone said from behind her.

She twisted around and laid eyes on Rick Malverne, already getting handcuffed by the other DEO agents who had come into the building with her.

"He was trying to get out the back." One of the agents said as she turned him to face Alex.

"Hello agent Danvers," Rick said, his voice calm and collected.

"Where did you take her? Why did the camera turn off?" Alex responded. She knew she was out of control of her emotions, but she couldn't reign them back in.

"I'm afraid I can't answer the first question, but as for the second, did you really think I'd let you talk to dear old sis for as long as you want?" He said, "I set it up to turn off on my command, and it won't ever be able to turn back on. You won't get to see her again until I get what I want."

Alex lunged forward but stopped short of hitting him, instead she grabbed his hair and yanked it as hard as she could.

He yelped and struggled against her, losing his calm composure.

Alex leaned in, keeping her eyes on Rick as she spoke, "Take him back to the DEO, we need to have a little chat."

Alex drummed her fingers against the table in front of her, forcing herself to listen the pathetic story of the man who kidnapped her sister.

He had already explained how he knew Kara was Supergirl, from an incident that happened years ago when Alex and Kara were growing up in Midvale.

She had to hand it to him, he was smart.

"My father was my lifeline," he said, pulling Alex back into what he was saying, 'He saved me from my mother and moved me away from Midvale. Even though he was always struggling, he always made sure there was food on the table, and he got me enough money to go to college. But then three years ago, the state took him away from me."

"He killed two people," She said.

"They had it coming, And now I'm going to rescue him like he rescued me." He paused, enjoying the disgusted look Alex gave him.

"But I can't believe we're still talking about me, you have hours, maybe minutes." He said.

"Until what?" Alex responded, "What are you going to do from your little prison cell if we don't meet your demands?"

He smirked again, "Oh I figured you would catch me. granted it wasn't ideal, but," he lifted his hands to gesture at Alex, "You're smart, I had to prepare for you finding me."

"And how did you do that?"

"When that camera inside your sister's cell shut off, it wasn't the only thing that happened. I rigged the place to start filling up with water. If my timing is right, and it is, Supergirl will be taking her last breath in about 1 hour."

Alex didn't get angry often, it was a sign of weakness to her and she didn't ever want her judgment clouded by her emotions.

But Alex was angry now.

She was angry at Rick for endangering her sister and she was angry herself for not being able to stop it.

In a display of that uncontrolled rage, she pinned Rick against the wall, digging her forearm into his throat as she held him in place.

"Where is she?!" Alex yelled.

"You know if you use half this much gusto in springing my dad, you'll have your sister back in no time." He choked out.

"Alright that's enough," J'onn said, pulling Alex off of Rick and dragging her away from him.

He had been watching from behind the two-way mirror, so he must've come in once he saw Alex attack Rick.

Alex shook of J'onn's hands and stared back at Rick, who was returning to his seat, apparently unaffected by what just happened.

A thousand words came to Alex's mind, but she couldn't think clear enough to form any of them together.

"Tick tock," Rick said as Alex walked away.

Her fists tightened at her side, and if it weren't for J'onn next to her, Alex was sure Rick would already be on his way to the emergency room.

Alex began pacing as soon as J'onn closed the door.

"Alex," he said, his voice stern with disapproval.

"I'm sorry," Alex mumbled as she paced, "I shouldn't have done that, I- I was just…"

"Scared," J'onn filled in for her, softening his expression when she nodded.

"I'm so scared," she said quietly, flopping down in one of the chairs as she ran her hands up and down her pants leg, wiping off sweat.

"I can't- I can't lose her, I can't," she said, her voice breaking as she tried to hold back tears.

J'onn sat in a chair next to her, pulling her into his arms, "I know, but you won't," he said, "We'll find her."

His voice was calming and steady, an anchor for Alex to hold on to, and she almost believed him.

Suddenly the door burst open and Winn appeared.

"We found her!" He said, grinning from ear to ear.

"What? How?" Alex said as she and J'onn stood up and followed Winn out into the hallway, trailing behind him as he spoke.

"She managed to find a way to wire herself into the camera in the room, so all I did was track the IP address of the camera, we got the location."

Alex smiled for the first time all day, not only had they found Kara, but they did so because Kara used a trick Alex had taught her.

"What are we waiting for then? Let's go!"

The warehouse was dark and quiet, so quiet that Alex could hear her pounding heart in her ear as she moved across the building with the rest of the DEO team.

This was were Kara was supposed to be. It had taken 58 minutes to get to the location, so if Rick was right about the time, Alex only had a few minutes left to find her sister.

She stepped a little faster.

She stopped at a locked door in front of her, the door handle was stained with blood.

Alex signaled to the agents and they began working on opening the heavy metal door.

It took 1 minute and 15 seconds, Alex was counting.

She burst through the door the second it was open and found herself face to face with an empty room that only contained what looked like a large fish tank.

In the tank, floating in water, was Kara.

"Get back!" Alex yelled to the agents who had gathered around the tank to try and find a way to open it.

She pulled out her gun and aimed it carefully at the tank so that it hopefully wouldn't hit her sister if it went through the glass.

This wasn't the safest option, but it was the only one they had.

She fired.

The glass cracked but stayed intact.

She fired again, and again, and again, on her fifth shot she was starting to doubt that she would ever break through.

She would come this close only to watch her sister die in front of her, separated by 5 inches of glass.

But it broke on the fifth shot.

An unconscious Kara came rushing out of the tank as Alex went rushing against the water to catch her.

Alex lowered Supergirl to the ground and felt for a pulse.

She couldn't find one.

No.

This was not how it would end, Alex would not loss Kara here, not after being so close.

She shoved her shaking hands into Kara's chest and began chest compressions as agents gathered around to watch, unsure what to do.

"Come on Supergirl, wake up!" Alex yelled, slamming her hands a little too hard into Kara's chest.

And then Kara was breathing, coughing and spluttering and gasping, but breathing nonetheless.

"Hey, I got you," Alex whispered as she moved to help Kara lean up.

Kara recognized the voice and immediately latched on to Alex, weakly grasping onto her shirt collar.

"It's ok, you're ok, I'm right here," Alex muttered, pulling Kara into her arms as Kara's breaths began to even out.

"Alex," she whispered into Alex's ear so quietly that no one else could her it, "I'm never going swimming again."

Alex let out a watery laugh and held Kara a little bit tighter.

Kara's grip was getting stronger and her hold on Alex was almost suffocating, but for the first time all day, Alex felt like she could breathe.

Hope you all liked it, thanks for taking the time to read it and have a great day/night!
