Kara rushed around her apartment, decorating it with balloons and streamers. Everything had to be perfect for Alex. She would be here any minute and Kara was getting flustered. 'I hope this is good enough...' She jumped when there was a knock at the door. 'Why am I so nervous?' "Come in!"
Alex stepped inside and was immediately caught off guard. "Uh... Is today a special day and I forgot about it? Please tell me that's not the case..."
Kara shook her head. "No, it's... It's nothing really." She rubbed the back of her neck, questioning if she should've even tried to fo this. "It's just that, well... Winn got me this cool calendar that has a bunch of national days on it and... look at today's date."
Alex looked at her sister for a moment, then walked over to the calendar hanging on the wall. "National Siblings Day." Alex's expression softened and she felt a slight lump in her throat. "Oh, Kara..."
"And look, uh, I got you this..." Kara handed Alex a small box and took a step back.
When Alex opened it, all she could do was stare at it. It was a cupcake, just like the one she got Kara for Earth Birthday, only this one had words on it: 'Best Big Sister Ever!' The lettering was slated and slightly too big, so it was clear Kara had somehow managed to do this all by herself.
"I-If you don't like it, that's okay, I just wanted to try something," Kara rushed out, taking Alex's silence as a disliking.
"Like it? Kara, I love this, thank you!" Alex set the cupcake down then pulled Kara into a tight hug. "And you're the best little sister ever," she fondly whispered into her hair.
Kara buried her face into Alex's shoulder and breathed out. She had been worried that Alex would find this too be childish, dumb, or not worth her time. She was glad that wasn't the case.
"This isn't dumb, Kara."
Kara froze. "Did I say that out loud?"
Alex laughed and squeezed her middle. "No. But I know you better than anyone. You're so caring and you just want to give people hope. This is amazing, Kara. Thank you."
"Ah, well... You're welcome, Alex," Kara responded, blushing hard.
"I just wish Winn gave me a calendar also so I could've done something for you too...," Alex continued, feeling a little guilty.
Kara let her sister go. "Aw come on, you don't owe me anything. We've always done earth birthday for me, but you never had anything special. This is your special thing." Kara was sincere with her words. She did feel like she took the spotlight away from her sister sometimes, so she figured this was a way of giving back to her.
Alex fondly shook her head. "You were the star. I didn't need anything special."
"Oh just shut up and eat your cupcake," Kara insisted, playfully pushing on Alex's shoulders.
"Okay, okay, fine. Hey, let's split it. You can't be siblings when you're the only one," Alex pointed out, picking up the cupcake.
Kara grinned. "Let's do it!"
Alex smiled back and split the cupcake down the middle and handed Kara the other half. "I'm glad you came to earth."
Kara's eyes began to water a little. "I'm glad Kal brought me to your family." The two sisters cheered their cupcakes and each finished their pieces quickly. "Ha, now I wish I thought to get a second one. Oh well, it's not like Noonan's doesn't know me by name already," Kara laughed nervously, trying to fight the lump in her throat caused by Alex's sweet words.
"Oh, Kara." Alex tugged her sister forward and pressed a lingering kiss to her forehead. "I love you so much."
Kara tucked her head under Alex's chin as a few happy tears escaped. "I love you too."
Alex closed her eyes and thought about when Kara first came into her home. She was small, innocent, and had just lost her entire world. Despite all that, Alex had resented her. She didn't want an alien for a sister, she told herself. She's too weird, she'd say. Alex held her a little tighter and kissed the top of her head. "I'm sorry for the things I said to you as kids. I didn't know what I had in you."
Kara reached up to lovingly pet Alex's hair. "Don't apologize, I wasn't exactly the best guest in your house."
Alex laughed at the memories. "Yeah, you were a bathroom hog. Well, you still are."
"Hey!" Kara playfully pushed her away. "Am not!"
Alex pushed back. "Am too!"
Kara poked Alex's side with her finger. "Am not."
Alex flinched away, which was a mistake because two seconds later they were both on the couch and Kara was tickling her with no mercy. "Okay, okay, I take it back, please stop!"
Kara giggled and did as she was told. "I wonder what the other agents in the DEO would think if they knew their top one gave in to being tickled."
Alex tapped Kara's nose. "It was a fluke and you know it."
Kara grinned. "Hey." She opened her arms expectingly. "Cuddle."
Alex rolled her eyes and scooted closer. "Bossy."
"You're one to talk," Kara teased, nuzzling into her shoulder.
"... Yeah, that's totally fair," Alex admitted, leaning her head against Kara's. She relaxed when she felt Kara's arm wind around her waist. She felt safe; it felt like home. "Thank you for today, Kara. I couldn't have asked for a better little sister."
Kara snuggled closer and kissed her cheek. "And thank you for putting up with me all these years." The two sisters then closed their eyes and took in the warmth of the other. It was quiet for a while, neither wanting to ruin the moment, until... "Hey, did you know there's a national kale day, but not a national potstickers day? What's up with that?!"
