Super Swap (A Supergirl Fanfiction)

Four

(Kara's POV)

Loud footsteps came from the hall, but without my powers I can't recognize exactly who it is and what they are doing. Grasping Lena in my arms, willing her to stay alive and be strong, I kept my eyes focused on her instead of the banging outside the door. The sounds outside got louder and then made a thud followed by a loud bang. The door of my quaint loft shot to the ground as Alex forcefully kicked it in, leaving a footprint sized dent and a gaping entrance into my apartment. She ran in, straight to her sister, followed by J'onn and a couple other DEO agents. 

Alex looked down at Lena's almost lifeless body and then up to mine, her expression turning from worried to angry. "WHAT DID YOU DO LENA!", Alex screamed at my face, glaring harshly, but  I didn't really notice because I was so fixated on Lena. Alex grumbled over to me and picked me up by the throat, choking me as if it would undo our current situation and save her sister. "WHAT DID YOU DO TO KARA LENA!", she screamed again but instead of just anger, I saw sadness in my sister's face, hopelessness, desperate for answers. 

"L-li-livewire..", was all I could manage to make out, barely able to breathe. She threw me down and came at me again.

"What did she do to her Lena?"

Catching my breath, I mumbled, "Kryptonite. She injected kryptonite into her body with a syringe. I was able to scare her away with some water and called you right after. We need to get her to the sun lamps immediately." Taking my word, Alex ran over to Supergirl and knelt down. "J'onn you need to fly her out of here now!", she screamed assertively. Before J'onn could grab her she started to convulse. Visibly crying, Alex and I both covered our mouths, terrified for the most important person in our lives. J'onn quickly picked her up, cradling her in his arms carefully, and flew out as fast as possible, for he was worried for his adopted daughter as well. 

Once they left my now human eyesight, I gravitated back over to Alex. Unlike how I saw her moments ago, stern and sure of herself, she was collapsed on the ground, sobbing over her sisters incident. I have never seen her like this before, so vulnerable and afraid, not even over our dad's 'death' when we were children. Unsure of what the right move was in Lena's body, I couldn't help but sit down next to her, pulling her into a hug. Instead of fighting Lena away, Alex embraced her this time, leaning her head into my shoulder, soaking my shirt with her tears. "She's gonna be okay Alex, Kara is going to get through this."

"Di-did you see her j-just now? Does sh-she look like she I-is going to be okay? How could I let this happen? I'm supposed to protect her, watch out for her, keep her safe.", Alex cried out to me. I couldn't help but just listen, unable to make out a sentence that would make her feel okay. "Poor sweet Kara doesn't deserve this, I do. I'm the one that allowed this to happen to her. It is my fault. It is my fault she is going to die, Lena, it is all my fault." Managing to finish that sentence, she completely broke down, sinking her head deeper into my frail body. Crying, I leaned into her unable to see the sight of Alex so hurt and afraid. I couldn't stand it anymore, she should know her sister is right her, that I am safe and Lena is the one battling to stay alive and not the other way around. 

"A-Alex.." I whispered. She tilted her head up and looked at me. "Your sister isn't the one almost dead and she didn't just get injected with Kryptonite and she wasn't flown away. She is okay. I am okay."

"Wh-what do you m-mean? Is this some sick joke Lena?"

"It's me Alex, it's Kara.", I said, hopefully sending the right message and explaining this difficult situation to a very broken Alex. "Lena is me right now, she is in my place and I am in hers. I'm Kara, your sister and I am here for you Alex." I looked into her eyes as I would usually as her very loving sister. Reaching for her hand to console her, she pulled away.

"This isn't funny Lena. What the fuck is wrong with you! Kara is struggling to stay alive and you are here bullshitting me? Get away from me!", Alex jolted away, resuming her stern angry death stare. 

"I'm not lying Alex. I am Kara."

"Okay then, 'Kara'", she mocked using air quotes, "Prove it. Tell me something only Kara would know."

Thinking for a minute to find the perfect memory or secret for her to believe in this ridiculous situation, I found the one that would convince her that I truly was Kara Zor El Danvers, her favorite person in the entire world. I began my explanation, hoping she would understand. "When I first came to Earth from Krypton, I was a scared little girl, terrified of almost everything, having just lost my entire world. You and Eliza and Jeremiah took me in as one of their own. Having all of these special powers and the extra attention made me their golden child and you hated me for it. For months, we would always be fighting. You didn't want me there, and you definitely did not want to be seen with the weird adopted kid at. school. And worst of all, our parents put protecting me on your shoulders, sacrificing your life for mine. Once we got closer after solving Kenny's murder, things got better between us. Though we began to enjoy each others company, you still had the burden of being my sister. Every wrongdoing of mine was blamed on you, even if it was my idea or if you weren't even involved at all. Especially when we went on late night flights, sneaking out of the window together onto the roof. The type of flights that got Jeremiah sent away to Cadmus, forever changing your life. It isn't fair Alex. You shouldn't have to feel like protecting me is your job. I'm sorry. I didn't know you felt so responsible for me until I just saw you like this, all broken and terrified. I want you to be happy Alex, I want you to live your life without feeling so guilty for not saving me. What happens to me is not you fault. I love you Alex, forever and always." I finished the monologue, tears streaming down my new face. 

"K-Kara?" Alex looked straight into my eyes and practically jumped on me, pulling my body into a hug, gripping me tight, too tight. 

"Okay, easy there tiger, don't have super strength or invulnerability and this kind of hurts.", I said grunting from almost being suffocated.

"Kara oh my God I am sorry I didn't believe you. How did this-"

"I'll explain later.", I interrupted. "What we need to worry about is saving my body, saving Lena."

Alex nodded in agreement, pulling me in for another hug.
