Chapter 4

It didn't take Kara long to change. Despite not using her super speed, she was pretty fast changing into her fresh clothes. Kara put her Supergirl uniform in a bag and exited the sun room to see Alex biting her lip and staring off into space.

Kara gently taped Alex on the shoulder and said, "Okay I'm ready to go, can you help me walk?"

Alex looked at her and smiled, "Of course."

Each wrapped an arm around the others waist and Kara leaned on Alex for support. Kara quietly breathed in the scent of Alex's hair, hopefully without her noticing. Slowly the agent led the alien to her car, carefully so she wouldn't hurt her. "How are you feeling now?" She whispered.

"I'm better, my leg is still sore as you can tell but all in all, I'm great." Kara responded. Alex smiled and continued their walk.

As they arrived to the vehicle, Alex leaned Kara against the backseat door and opened the passenger door for her. "Okay easy does it now." Alex coaxed as she helped Kara into her seat. She even put her buckle on for her. Kara blushed at the gesture and thanked Alex.

The two of them drove back to the city making small chit chat, nothing too serious. Kara almost let it slip that she went into Alex's office, but luckily she was able to hold her tongue.

Miraculously Alex noticed that they never hit a red light. She actually thought that this time, the universe was cheering her on.

Pulling up to Kara's building, Alex quickly got out of the car, grabbed the bag carrying Kara's suit and opened the passenger door before Kara even got her seat belt off. Following their same position, Alex helped Kara up the steps, taking each one gently.

As they finally reached the elevator, Alex leaned Kara against the rail and pressed the button for her floor.

'Come on, come on' the brunette thought anxiously. This elevator always went slow and it really irritated Alex. Once they passed the third floor, Alex's gaze swept over to Kara's face. Hazel eyes met blue ones, and for a brief second, Alex had the strongest urge to press the emergency stop button and kiss Kara right there and now. Instead though, she smiled and retracted her hand further away from the very tempting red button.

The finally arrived to Kara's door and Alex immediately put her spare key in the lock. Kara was puzzled by Alex's rush, but she wasn't going to complain. She leaned on Alex one last time as they entered. Alex maneuvered Kara to the couch and gently helped her sit down.

"Hey can you get me some water?" Kara asked shyly. She wasn't used to not being able to move on her own, so it was kind of embarrassing asking Alex for things.

Alex only smiled at her and said, "Sure thing." As the brunette walked to the kitchen, she felt Kara's eyes on her. Lucky for Kara though, Alex didn't know WHERE she was looking.

Alex brought back Kara her drink and sat next to her in the couch. Kara downed the whole glass and thanked her quietly. The two of them spent a short amount of time exchanging small glances and not uttering a word. Alex's mind was racing.

'What should I say!'

'Should I tell her I saw her videos?' Kara thought.

'What if she rejects me?'

'Oh screw it, just say something Kara!'

What was 30 seconds, felt like an eternity for both of them and finally they got the courage to speak.

"I was won-" both of them started. They looked at each other and laughed at how they had talked in sync. Once they contained their amusement, Alex spoke first.

"Do you want to go first?" She questioned.

"Oh sure." The Kryptonian responded. Her heart was beating like a drum and she could hear Alex's going almost as fast as her own.

"I... uh... I..." she stammered. Kara was panting now. How can she go through with this? What will Alex say? What if this is all a mistake! All of these thoughts roared in her mind making her shake and pant even harder. Alex noticed this right and and realized Kara might be having a panic attack.

She took Kara's hand in hers and placed her spare hand on the aliens chin to align their faces. "Hey Kara, just breathe okay? Hey, look at me and breathe." She said soothingly. Kara stared into her hazel eyes and her gasping slowed to a steady pace.

"I-I'm sorry I don't know what came over me." She rasped, squeezing Alex's hand.

The brunette nodded and said, "Do you want to continue with that sentence?" Alex didn't want to push Kara, but she was honestly dying to know what the alien was going to say.

"Yes, I can do that." She took one more deep breath and said, "I went into your lab earlier, when you were gone." This sentence made Alex freeze. She was really hoping Kara didn't get on her computer.

"I got on your computer-"

'Damnit' the agent thought.

"And I found your video logs about me."

Alex didn't respond to this at first. She let it all sink in and her face went red. "Oh.. what did you see.."

"I saw only a few videos, some from when I became Supergirl, another when you talked about how you didn't like James or Winn, and one more..."

Alex's heart was thumping against her chest like a woodpecker. 'Please for the love of God tell me she didn't see the drunk one.' She prayed.

"Did that last one... involve alcohol?"

Kara only nodded and Alex retracted her hand so she could face palm herself. She probably should have deleted that one.

"Alex... I had no idea you had felt that way about me. After all of these years, why didn't you tell me?" Kara's face showed no signs of hurt or anger, just plain confusion.

"Why didn't you tell me how you felt?" Alex countered. She didn't mean to sound like a smart ass but she couldn't help but ask.

Kara's face immediately went red and she shuddered, "W-What do you mean?" Alex turned her head away from Kara's gaze, ashamed.

"I might have found your diary. It was completely by accident though, I swear!" Kara's face only grew redder, and her hands were starting to get sweaty as Alex continued, "I read about how you had feelings for me too, and how me not noticing really hurt you. The reason I didn't tell you was because I was afraid you would hate me and we could never be the same."

Kara nodded her head in understanding and wiped her hands on her sweat pants and said with a dry mouth, "So... we both know about each other now."

"Yes we do..." Alex whispered.

"What now?"

" I don't know Kara!" Alex groaned. "I mean, we both have feelings for each other and we're not real sisters, but what if the word got out and people started asking questions? Oh god what if mom found out! She would probably kill me!" Alex was the one panicking now, "What if it doesn't work out with us and we end up never talki-"

Alex is cut off short when Kara surprises her with a passionate kiss. Alex froze at first but quickly melted into Kara's lips. She wraps her arms around Kara's back, pulling her closer as Kara slides one hand through the brunettes soft hair.

When they come up for air, Kara expects another go but Alex stands up and takes a few steps back. "Oh God Kara - what if this is a mistake, I mean what if this is this just some, one and done situation?!" She gasps desperately.

'Okay, enough of this.' The blonde thought boldly. Kara painfully stands on her own and limps to Alex's position.

Before she can say anything, her leg gives out and she almost falls but Alex is there to catch her. As the agent helps Kara stand, they are about an inch from each other. Kara places her arms around Alex's neck for support and Alex instinctively rests her hands on Kara's hips.

"Does this feel like a mistake?" Kara whispers before she brings Alex in for another kiss.
This one feels like a wildfire in their chests. Kara slips her tongue on Alex's lips and Alex welcomes it. Alex can't help but notice the tears falling down her cheeks as Kara deepens the kiss even more.

When they part, their foreheads meet and they gasp for air.

"No that didn't feel like a mistake." Alex whispered. Kara giggled at that and responded, "Good because I would have kissed you again if not."

The two of them laughed and held each other for a few moments before Kara broke the silence.

"I love you Alex." She whispered. Alex trembled at these words. For so many years she had wanted to hear this and now that she has, it feels like her whole world has changed.

"I love you too Kara." She said. Kara let out a tear and kissed Alex again.

They ended up on the couch, watching TV and exchanging kisses through the night. Kara relished at the feeling of Alex's arms around her body and turned her head to her love.
"I love you so much Alex, never forget it." She whispered.

Alex smiled at her and gently kissed her lips one last time for the night. "I love you too Kara, you're all I need now."

And with that last remark they fell asleep, wrapped in each other's arms as their hearts thumped lightly in their chests.

The End.
