Chapter 1

Prompt: Cadmus uses Alex to get Kara. (Part 1 of 2)

"Come on. Pick up. Pick up." Kara tapped her foot against the floor, one hand on her hip, the other holding her cell phone to her ear. The phone rang several times before going into Alex's voicemail. She sighed and pressed the hang up button. That was the third time she had called today with no response. It wasn't like Alex to not answer. She started to fidget with her glasses. J'onn hadn't mentioned anything about Alex going on a mission. Maybe, she was hanging out with Maggie and had turned her phone off.

The thought threw a punch to her stomach. It had only been a week ago since her argument with Alex over Jeremiah. Though they had talked about it, the words still hurt. When she saw her with Maggie, smiling and happy, she couldn't help but feel jealous. Her words didn't light up Alex's eyes anymore. Ever since the argument, she could see the guarded look in Alex's eyes every time they talked. Trust had been broken that day, and neither of them knew how to get it back.

A piercing ring shot through her ear. The phone dropped out of her hand and crashed to the ground. Covering her ears, she soon followed, falling to her knees, trying to get away from the all-consuming, high-pitched noise.

"I hope you can hear me Kara Danvers."

Something in the back of her mind screamed "Lillian," but she could barely focus. The walls were starting to blur. And the pain, the pain that drilled holes in her skull and down her spine, was all she could think about and feel.

"There's someone I think who would like to see you. Don't you have a sister? Isn't her name Alex? Well, she's here and waiting for her Supergirl to come save the day. I'll send you the coordinates via your phone. Come alone." The pain stopped, and Kara was left on the floor panting for breath. Cadmus had Alex. Alex had been kidnapped. She tried to get up, but the room was spinning and she could barely breathe. Her phone vibrated next to her. Blinking her eyes a few times, she reached for it.

It was a text from a blocked caller ID. The coordinates weren't far from her apartment. The dizziness had dissipated, and she felt better now. She jumped to her feet. How could she have been so stupid as to not think Alex was missing? She knew Alex, knew her sister wouldn't go all day without answering her phone calls. How could she have let an argument so warp her thinking? How long had she been in the hands of Cadmus?

Throwing her glasses onto the kitchen counter, she quickly sped out of her clothes and into her suit. Jumping out the window, she took to the skies. It wouldn't take long to get to her destination.

She landed with a thud outside of what looked to be an abandoned warehouse. She tried to zero in on a heartbeat, a breath, anything that signaled Alex was still alive. There was nothing. Using her x-ray vision, she scanned the area. There was no sign of any living creature.

Slowly, she walked into the building, listening for anything that might sound off. Still, there was nothing. Everything was shrouded in darkness.

She saw something move on the floor. Edging cautiously, trying to keep her steps silent, she walked toward the dark mass lying on the ground. The mass made a muffled sound. She would recognize that voice anywhere. "Alex?" She ran the rest of the way toward her sister, seeing her better now that her eyes were adjusting to the darkness. "Alex? Are you alright?"

"Kara. You have to get away. They're coming for you."

"I'm not leaving without you." Kara felt for Alex's hands and ripped off the handcuffs encircled around her wrists. "Are you hurt? Do you need help walking?"

Alex shook her head furiously. "You don't understand. They didn't touch me. All they wanted was you."

Sharp pain suddenly exploded in her right side. It burned, burned like kryptonite. But that couldn't be right. The world titled to the left and her head collided with cold concrete. She could hear Alex screaming at her. She looked up. There was another person. This person was holding something green. The face was blurry, and everything seemed to be growing dark. Why did she feel so lightheaded? Why was there so much pain? Then, there was nothing.

Her head pounded. It felt like that one time when Mon-el gave her too much to drink at the bar and she had a hangover the next day. Except, she didn't remember going with Mon-el to the bar last night. She was with…

"Alex!" She shot up, but pain punched her in the side and back down onto the floor. She lifted her head slightly and saw blood oozing from her side and dripping onto the concrete. She felt dizzy, and she laid her head back down. From what she could see, she was back at Cadmus, back in the cage they had put her in before.

There was a groan. She knew that groan, knew that voice. "Alex?" she whispered. She struggled to push herself up, biting her lip to keep from screaming. The wound in her side burned, and the blood kept dripping. Using her forearms, she crawled over to the other side where Alex lay on the floor, dried blood on her temple. She began to sit up, using the bars for support, and stretched out her arm toward her sister. "Alex?"

Her sister moved slightly and then looked up. "Kara? Is that you?" Her eyes blinked groggily. Kara tried to go back through what she had learned from talks with Alex while she was in medical school. Could Alex have a concussion?

"Yes, it's me. Are you okay?"

Alex slowly sat up, raising a hand to her head. "I'm fine. They hit me on the head really hard though. It hurts like hell."

Kara sharply inhaled as the pain spiked in her side again. She put a hand to the wound. Alex's eyes widened as if she had suddenly remembered something. "You, you were stabbed. Lillian stabbed you with a kryptonite blade."

Kara tried to smile, tried to hold back the grimace as the wound grew hot, flashing with sharp bursts of pain. "It's not as bad as it looks." The room began to spin again. She could barely make out Alex glaring at her.

"The truth, Kara."

"Okay, maybe it is."

Alex moved closer to the bars. "Take off your hand. Let me see."

Kara slowly removed her hand, and Alex grimaced at the sight of mangled flesh. "It does look bad."

Alex slowly reached a hand out to grasp Kara's. "They stitched part of it up, that's why you're not bleeding as much as you should be right now. They did a terrible job though. I wonder why they would try to stitch you up but not fully?"

White hot pain hit Kara in a fluid motion, and she fell against the bars, gasping for breath. "Kara! What's going on?" She could only look at Alex, tears blurring her vision. She couldn't breathe. Why couldn't she breathe? Just as suddenly as it had come, the pain went away. She lay against the bars, panting.

"What? What just happened?"

Alex gripped Kara's hand tighter. "I don't know."

"You're both awake. Good." They turned. Lillian strode into the room, flanked by two of her men. "Did you like the present I left you?"

Alex stood up and rushed toward Lillian, gripping the bars. "What did you do to her?"

Lillian looked at Kara, and Kara couldn't help the fear that sent shivers down her arms and into her chest. "That wound in her side was a little messy, but it presented a wonderful opportunity." She pulled some sort of device out of her pocket. "You see this?" She waved it at Kara. "This is what gives me power over you." She pressed a button.

Kara began to scream. The pain, the pain was too much. "Alex! Make it stop! Please…" She shook against the bars, hands curling against her side. "Please…" The pain stopped. She kept her hands close to her body and looked at Lillian who was kneeling in front of her prison.

"I control you now. You don't do as I say, and I press the button on this device. You see, while you were unconscious I took precautions to implant electrodes in your body. I press the button, they shock you." She stood up. "Do as I say, and you'll find it's easier on everyone to obey. I'll give you a moment to think about it."

Lillian began to walk out but stopped and glanced back at Alex. "I want to know all the DEO's precious little secrets as well. I hope your sister will provide ample motivation for your cooperation." The click of her heels resounded on the concrete and faded away as she walked out.

Alex pounded on the bars before moving to Kara and sitting down. "You shouldn't have come for me."

Kara gave a short laugh, before curling further into herself. Her whole body hurt. "You're my sister. I couldn't let you face Cadmus alone." She coughed, the movement sending all her muscles into painful spasms. "I'm scared Alex. How are we going to get out of this one?"

Alex leaned against the bars and started to brush Kara's hair with her fingers. "We'll find a way. We always do. You just have to trust that help will come."

"And if not?"

"Then we'll face whatever comes our way together."

Kara reached out with one hand and put it on Alex's knee. "Together."
