I do not own Supergirl or any of its characters.
I love the relationship between the two sisters in the show so this is just some fluff between the two sisters. Sorry for any mistakes I am not the best at proof reading.
Kara Danvers was sitting at her desk looking through some papers. The day had been quiet so there was no need for Supergirl. Kara felt herself drifting and decided that she needed some coffee, so she made her way towards the elevator to go downstairs and get her coffee from her usual cart. Which, in her opinion, had the best coffee in the galaxy. The elevator dinged and the doors opened drawing the blonde from her thoughts, Kara shuffled into the elevator, pressed the button and watched as the doors close only then did she realise that she was alone. Taking a couple of shaky breathes Kara tried to compose herself. "This is stupid I have taken the elevator hundreds of times before and been fine," Kara thought to herself. Tears began to fill her eyes and she tried to blink them back hurriedly, "You are Supergirl, you fight the worst aliens there are," she told herself trying, in vain, to calm herself down. She pressed her body tightly into one of the back corners and tried to stop the shaking but no matter how hard she tried she could not get a hold of herself. She knew she was having a panic attack and just wanted to get out of the elevator as soon as possible but it seemed to be taking forever. The tears were now streaming heavily down her cheeks and her breathing was all over the place. After what seemed like a lifetime the door opened and Kara uncurled herself from the corner and looked through the doors to see a few people looking at her. Quickly she ran as fast she could out the building and outside into the open air. She took in a couple of deep breathes, she had completely forgotten about the coffee the only thing Kara could think about was she needed someone and that person was Alex.
Kara was having an internal battle with herself. She wanted her big sister but she didn't want to be an inconvenience. She knew her sister was busy at the DEO and she didn't want to disturb her. The blonde also new that she had to get back to work because the last thing she wanted right now was to be yelled at. The tears were still running down her face but her breathing was starting to balance out. Kara wanted to seem strong always. One of the things that she hated was that one moment she was Supergirl fighting aliens and protecting the earth and the next she was crying after a panic attack and wanting her sister more than anything on the earth. Kara looked at her watch, two more hours, "I can do that," she thought to herself, "I can push through for two more hours." Getting up, the blonde took a deep breath and wiped the remaining tears off her face before marching back inside the building and taking the stairs back up to her floor. When she was up there she went back to her desk, no one even looked at her, sometimes Kara thought no one even new she was there. Sitting down she resumed making her way through the mountain of paperwork on her desk. She was about three quarters of the way through when the day officially ended and she was finally able to go home.
Kara was making her way through the crowded streets trying not to think about how anxious she was. She was making her way to Alex's apartment because she was staying there now because hers had flood damage. Tears filled Kara's eyes again, people were bumping in to her and she was getting nervous. Taking in a few deep breathes Kara decided to take a break and sit down. She sat on a bench on the side on the path and tried to relax. She wished she was at home right now so she could calm down in peace instead of being on the side of the street surrounded by noise. It was very loud anyway but with her super hearing everything was so much louder. Gripping the side of the bench Kara tried to calm herself down. She felt the metal being crushed in her hand and in panic she removed her hand and put it in her lap. "Great," she thought, "Now I am destroying things." The blonde new her thoughts were getting the better of her and she tried desperately to stop them, though she knew it was useless. The only person who could calm Kara down right now was Alex. "Alex," Kara whispered to herself. Checking her watch, she realised that her sister would be home by now, desperate to see her sister Kara could up and almost ran through the streets to get home. Tears were streaming down her face but she didn't care, all earlier thoughts about being an inconvenience had left her mind and now she was solely thinking about getting to Alex. Getting to the building in record time, apart from when she was flying, Kara ran up the stairs avoiding the elevator because she knew she couldn't do that again today and arrived outside the door. Fumbling around her bag to try and find the keys Kara felt herself getting more and more desperate to get inside. Getting frustrated, Kara tipped the bag upside down and began making her way through her items on the floor her eyes were blurred from the tears and she collapsed onto her knees and began sobbing loudly, she just wanted to get inside and see her sister.
Alex had been sitting on her couch when she had heard the commotion outside the door. At first, she thought it was someone who had just dropped their things but then she heard the crying and Alex would recognise that cry anywhere. That was the cry of her little sister. Flinging open the door Alex took the sight in before her. There in front of her was Kara on her knees, surrounded by her things, crying loudly and shaking. Instantly Alex took up her big sister mode and bent down to Kara, "Hey, hey, sweetheart it okay, Alex is here," Alex carefully reached her hand out to touch Kara trying to scare her. At the sound of her sister's voice Kara looked up her eyes locked onto Alex's and almost instantly a sense of calm overtook her. Alex offered a hand to help Kara up and Kara took it slowly making her way to her feet. Alex let the blonde into the apartment and sat her down on the couch before making her way back outside to pick up the girl's belongings. Once all the items had been gathered Alex closed the door and made her way to the couch where a teary-eyed Kara was sitting. Gently lowering herself onto the couch, the brunette reached out an arm and watched as Kara leaned into her, taking some deep shaky breaths. Turning her head Alex placed a firm kiss on the girl's temple before asking, "Do you want to talk about it?" She then felt Kara shake her head against her chest. Alex gave a small nod, she would not push her now but she would get the girl to talk about it eventually because Alex had learnt the hard way that it is not good for Kara to keep things bottled up all the time.
About an hour later the tears finally stopped and Kara had managed to get her breathing under control. "Sorry," Kara whispered, it was so quiet that Alex almost missed it, pulling away from Kara a little, Alex looked at the girl trying to understand what she was apologising for. "What do you mean?" Alex asked the girl.
"I came home in tears and you have had a long day and I was an inconvenience to you and I really didn't mean to be so I'm sorry," Kara said quickly almost stumbling over her words. Alex sighed she should have expected this Kara hates getting upset in front of people and thinks the worst when she does.
"You have nothing to apologise for," Alex said firmly trying to get her point across. Kara put her head down but nodded so Alex knew that she had understood her. "Good," Alex said before pulling Kara back into the hug. The blonde wrapped her arms tightly around her sister trying to absorb as much love and comfort as possible. The two sat there for about twenty minutes before Alex pulled away again. "Are you ready to tell me what happened now," she asked. Kara gave a small nod before recounting the day's events that led her to end outside her sister's door so upset. "Oh sweetheart," Alex said, "You know you can always call me if you ever find yourself like that I will always make time for you." Kara looked down again but Alex put her hand under the girl's chin and gently pushed her head up so their eyes met. "You know this yes," Alex asked again,
"Yes," Kara replied before reaching out for another hug. Alex gave her a small smile before taking the blonde into her arms again. The two sat like that until Alex heard the other girl's stomach and declared it was time for dinner, "Pizza and Potstickers?" Alex asked and smiled when she saw her sisters face light up and begin to nod rapidly. Alex then ordered the take out before turning Homeland on the television. The two sisters began to watch the show in silence until there was a knock at the door and Alex got up to answer it. She paid the guy and brought the food over to Kar a who had paused the television and was waiting for her sister to come back over with the food. The two then proceeded to continue watching the television and eat the food that was in front of them. Once they were done Alex made her way to the fridge where she kept her and Kara's favourite ice-cream flavours where. Alex swore she heard Kara squeal in joy and the sight of her favourite ice-cream. The two of them ate the ice-cream together, talking and laughing with each other until Alex saw Kara yawn and decided that it was time for them to go to bed. The two of them went into separate rooms and got ready for bed.
Kara had been lying in her bed for half an hour when she gave up trying to sleep. After the long day she had she didn't want to be alone, so she quietly got out of bed and shuffled across the floor until she was standing outside her sister's room. Taking a deep breathe the blonde reached out and knocked on the door. She stood there until she heard the quiet "Come in," of her sister's voice. Kara awakardly made her way into the room. Alex had turned on the lamp next to her bed and had sat up looking at Kara to see what she wanted. "Umm I…" Kara trailed off running her toe along the cracks in the wood of Alex's floor. Looking at her sister Alex knew what Kara wanted, she had always been a cuddly person which was one of the many things she loved about her sister. Reaching her arm out Alex said, "Come here." Immediately Kara's face relaxed as she made her way over to her sister and climbed into bed with her. Alex turned off the lamp beside her bed and laid down next to her sister wrapping her arms around the girl and pulling her close. She placed a firm kiss on the top of her head, "I love you," she whispered.
"Love you too," Kara replied snuggling deeper into her sister embrace and finally falling asleep.
