Prompt: Kara takes a kryptonite bullet for Alex.
Kara sat on top of one of National City's tallest buildings, enjoying her view of the sunset. The day had been long and hard, and she needed a couple minutes of silence to collect herself, unfortunately she didn't have long.
A noise pulled her out of her thoughts, sirens from police and fire trucks as they raced down a nearby street.
For a second, she thought about just letting them take care of it, after all the authorities were fully capable of handling non-alien threats, but then she thought about how this could be the one time that the police don't get there fast enough or the firemen didn't see that one other person, it could be the time that someone dies.
And that would be on Kara, she knew had to go.
With a sigh, she jumped off the building and flew to the site of the emergency, a huge fire that had spread to an apartment complex.
The firemen were desperately trying to get the fire out, but there were still people trapped inside.
Kara jumped into action, using her superspeed and freeze breath to travel into the apartment complex and get people to safety. She was so concentrated on the job she didn't even realize where she was.
This was Alex's building.
A minute later, when she rescued someone who looked a lot like Alex's annoying neighbor, the realization hit her.
"Alex, oh no!" She said suddenly, flying back into the building twice as fast. Her sister was off today and had told Kara she planned on sleeping in all day and watching movies.
A terrible sick feeling implanted itself in her stomach, the same feeling she always had when someone she cared about was in danger.
Ignoring it, she flew to her sister's apartment through the flames, finally reaching Alex's smoke-charred door.
She should have noticed as soon as she got in the apartment, should have noticed the uncharacteristic mess that filled the usually clean apartment, she should have seen the blood, she should have at least noticed the weakened feeling she got as soon as she entered the apartment.
But Kara noticed none of this as she raced through the apartment, all she could think about was where her sister was and how she needed to find her. I guess its true that love is blind.
"Alex!" she screamed, running through the apartment as she felt the building shake with unsteadiness. Moving faster, Kara slammed open the bedroom door, relief and confusion flooding her all at once.
Alex sat against the opposite wall, tied up and bleeding, as soon as she saw Kara, Alex's heart dropped. For once she was hoping her sister wouldn't find her.
An alien, one Kara had never seen before, stood in front of her sister, a gun in hand pointed at Alex's head.
"Kara run!" Alex screamed at the top of her lungs, her voice cracking with desperation.
And run Kara did, but not like Alex wanted. She ran to the alien, standing in between the man and Alex so he couldn't hit her.
Kara went to punch the alien back, but she didn't account for him having superspeed too, and she didn't expect him to shoot her in the stomach before she could do anything. But the most surprising thing was that it hurt, the bullet hurt. The man had shot her with kryptonite, and now it was in her.
"Kara!" Alex screamed again, desperately trying to move towards her collapsed sister only a few feet in front of her. The building shook dangerously and Alex knew they only had minutes left before it collapsed completely.
The alien who had shot Kara felt the shake too, and knowing the building was going to collapse, jumped out the window and flew off, satisfied with his work.
Alex crawled closer still, pain pulsing through her body and making her vision swim with dots. She didn't have long either, but she had to do something.
Kara was conscious, shifting and moaning as she clutched her stomach.
"Lex" Kara said, and Alex wasn't sure if it was out of pain or panic or both.
"I'm here" she said, reaching Kara's side and pulling herself into a sitting position, the dots multiplying as she did.
The building shook again, louder and harder, like a final warning.
"I've got you" Alex said, wrapping her hands around the wound, the touch forcing Kara to look at her.
"Its gonna… the building…" Kara said, as she forced herself to stay conscious and sit up, she had to get Alex out.
"I know…" Alex said, she looked around desperately for something she could use to get Kara to safety.
They were way too high up for the window, Kara couldn't fly and they'd both die from a drop this high. There was no way they could travel back through the building before it collapsed.
She knew she couldn't get Kara out of here, but she could still do something, even when all she had was herself. Alex would do whatever she had to protect her sister. She moved Kara slightly and began to put herself over her, using her own body as a shield to hopefully protect Kara enough that she'd survive the collapse of the building.
Meanwhile, Kara had come to the same conclusion as her sister, and she knew what that meant, they were going to die here. Even if Alex could, protect Kara, Alex was still going to die here.
And that would not happen under Kara's watch, she would do anything to protect Alex, she wouldn't let her sister die here.
"No," Kara said out loud, forcing herself to stand up, her feet swaying beneath her as Alex stood too. They both looked close to dropping.
Her stomach bleed furiously, pain shot up her chest and made her feel sick, her will to stay awake was fading, she had to move quickly.
Holding out her hand she grabbed Alex's. "I can still fly; we'll go out the window." Kara said, dragging herself towards the window and smashing it with the hand not holding Alex's.
Alex, smart clever Alex, knew something wasn't right. Had she not been hit in the head beforehand she would have realized the lie, but her pain-filled body was working slowly, so all she knew was something wasn't right.
"How-" she started but was cut off by the building beginning to shake, violently. This was not a warning; this was the beginning of its collapse.
"Let's go!" Kara screamed, standing on the windowsill before grabbing her sister around the waist and wrapping her arms tightly around her body.
Kara had her back facing the window, and with one final look at Alex to make sure she was safely pressed against her front, Kara leaned out the window, for a second trying to fly but knowing there was no chance it would work with the kryptonite still in her stomach.
At the last second Alex's brain suddenly caught up to the scene, realizing that there was no way Kara could fly with kryptonite inside her, and Alex realized the way her sister was holding her. Kara was sacrificing herself. "Kara no wait!" she screamed, but it was too late.
The firemen outside looked up to see two figures falling from the top of the building, before anyone could do anything, the girls hit the ground.
So I hope everyone liked it, I will obviously do another chapter and wrap this story up for you guys, so the next chapter will be up soon and will probably be real fluffy. Anyways, please feel free to leave a request or prompt. Have a great day/night!
