It was dark out when they finally got home. With their newly formed sisterly bond, Kara and Alex walked into their room, hand in hand, and collapsed onto Alex's bed.
"Today was such an amazing day, wasn't it?" asked a content Kara.
Alex answered,"It was honestly the best day of my life. I can't even remember the last time I saw you smiling so much. I really do love that smile."
"Y'know Alex? I think I'm starting to like it too. I haven't smiled this wide since... Krypton..." Kara's eyes welled up. "But after today, I might find it easier to come to terms with Krypton's explosion because I know that no matter what, I'll always have this family."
Alex wrapped her little sister in a hug. Tears dripped onto Alex's shirt, but somehow she just knew that those would be the last ones Kara shed for a while. "Kara, Kara. Hey. Look at me." She tilted Kara's head towards her. "You will always have us no matter what. Ok? Seeing you sad makes me want to cry too, Kara, because I can't imagine the pain you have felt in your short life. But I will be here, so you don't need to cry anymore, Kar. I know you can't forget Krypton, but you can move on."
Kara nodded in agreement, wiping some of her tears. Unsure, she asked,"You'll be there to help me? Because I can't do this without you. Move on, or even live. Without you."
"I promise I will always be here no matter what. I swear. But I'm gonna need you to stop crying just for tonight so we can end this day off with a bang. What do you say, Kara?"
"Deal. You promise to be here for me and I promise to try not to shed any more tears for Krypton. I know it's okay to miss it and I know it's definitely okay to cry. But, I also know that I don't have to cry over lost family anymore because I have one right here."
They looked into each other's eyes. Brown locked onto blue. And in that moment, their promises were sealed. They leaned in for a quick hug, before Alex pulled away asking,"So how do you want to end this day off? Something we'll both love, that will make this day even more memorable. Movie marathon? A prank on Mom and Dad?"
Kara considered her options thoughtfully before tentatively suggesting,"Alex, I've been wondering if... maybe... only if you want to... if I could take you flying tonight? I love the feeling of the wind against my face and I think our first night flying together should end off our first day as official sisters. What do you think? I mean you don't have to if you don't feel safe or if maybe you th-"
"Kara." Alex interrupted gently. "I think that is an amazing idea. I know Mom and Dad will not like you using your powers out in public, though."
"But Alex. It's practically dark out, and it's not like people are particularly watching the sky for a blonde alien flying around with her adoptive older sister. No one's even going to see us. We can't miss this opportunity!"
"Alright, alright Kara." Sure, she was worried that they might get caught, but it's so worth it to see Kara smiling. How could anyone resist those eyes begging her to say yes?
"YAY! Thank you, thank you, Alex. I can't wait to take you! But it might be a little cold, so you should grab a jacket or something. I'll be out on the roof whenever you're ready."
"Okay, don't forget to be quiet with the windowsill. Mom and Dad are probably reading or getting ready for bed." Kara nodded. Alex continued,"I'll be right out."
A mysterious figure watched from a distance as he saw two young girls climbing up onto a rooftop.
He watched them with a careful, analytical eye, waiting for something to happen. Something suspicious. Maybe even something alien.
So he could have his proof. And more importantly, so he could make his move.
