When Kara awoke, she found Lena's arms around her and legs entangled with hers. She felt butterflies in her stomach as she pondered on the events of the previous night. It was unexpected. She'd had feelings for Lena for years and never even entertained the thought that she might have feelings for her too. Her best friend, the CEO of L-Corp, the most badass, yet softest woman she'd ever met had feelings for her too. She placed a soft kiss on Lena's neck and slowly untangled herself from her. She put her suit on and flew to France to pick up breakfast for Lena, leaving a note for the brunette in case she woke up while she was out. Kara couldn't help but do flips and spins in the air as she excitedly shouted for joy. Nothing could ruin her mood… or so she thought. Once she returned to Lena's penthouse, she found a note from Lena beside her own. "I had an important meeting come up this morning. Sorry about skipping breakfast. Come to my office at noon for lunch and I'll make it up to you."

Kara frowned. She wasn't supposed to let Lena out of her sight. She'd failed. She looked at the bag she was holding, Nia was going to love breakfast this morning. She flew by L-Corp on her way to CatCo to make sure Lena was okay. She was in a meeting, taking notes. As Kara flew by the window, she couldn't help but smile. She was beautiful.

As the elevator doors opened, Kara found Nia waiting for her in excitement.

"Nia," Kara greeted, handing her the breakfast bags.

"Uhm, wow, France, thanks…" Kara walked and Nia followed. "Uh, what happened with you and Lena last night?"

Kara stopped and looked at Nia, panic on her face. "N-Nothing, why?"

Nia just posited ahead. Kara's eyes followed the direction of Nia's hand to her desk. She couldn't even see her desk, dozens of rose bouquets covered the surface and overflowed to the floor. Kara's mouth dropped.

"That doesn't look like nothing," Nia said. She walked over to the roses and pulled a card from one of the bouquets. She handed it to Kara. It read, 'I love you, Kara. -L'

"So, are you going to tell me how you went from best friends to the 'L' word in just one day?"

Kara blushed. "No, but you can take some of these roses so that I can have some space to work."

Nia pulled a face but picked up a few bouquets and went back to her desk. Kara rearranged the flowers and opened her laptop, ready to start her day. She decided to text Lena a 'thank you' first. She remembered that she hadn't checked her phone since last night and it showed. She had missed 17 calls from Alex. She quickly worried. She decided to check her messages from her sister before she called her back. Alex had been blowing up her message box all morning. Kara skimmed through the messages, they didn't make any sense, until she read the bolded and capitalised 'LOVE POTION! HE GAVE LENA A LOVE POTION! SHE FALLS IN LOVE WITH THE FIRST PERSON SHE SEES FOR 12 HOURS!'

Kara jumped up. She needed to get to the DEO as soon as possible. She took off in flight when no one was looking and arrived seconds later.

"Alex! What is going on!"

Alex turned to see her sister, alarm on her face. "Where have you been, Supergirl! Why are you not with Lena? We identified the assailant; he is a warlock. He wanted to get Lena to give him rights to L-Corp, thought making her fall in love with him would be the best way to go about it so he gave Lena a love potion. Has she been acting strange? Did she try to leave her apartment last night to find him? She didn't come to the DEO. It doesn't make sense."

"Lena is at work, I checked on her. She is fine. She was with me all night… she didn't seem phased by him at all. She didn't really even mention anything…"

Alex bit her lip, thinking. "Maybe something went wrong with the potion then."

"Or maybe she didn't look at him when she started to feel the way she did. She did say that she just wanted to get out of there… Maybe…"

Alex could sense hesitation in her sister. "What is it Kara?"

Kara took in a deep breath. "It was me. I was the first person she saw."

Kara felt her heart break as she said those words. It all came crashing down. Everything that had happened in the last 12 hours was a lie. She'd taken advantage of Lena. She did the very thing that she was terrified of doing. Her friendship with Lena was over. She felt disgusting.

"What do you mean? What happened?" Alex could sense the hurt.

"I- uh… I thought it was real. I went too far. Rao, Alex. I thought it was real. It seemed so perfect. I destroyed my friendship. I hurt her. I thought it was real." Kara's voice cracked as she spoke. She was filled with so many negative emotions. Tears welled up in her eyes, threatening to escape. "When does it wear off?"

Alex felt Kara's hurt, she did not know how to react. "Less than 10 minutes…"

Kara nodded as a tear escaped her eye. "I have 10 minutes until Lena Luthor hates me for what I have done."

At that Kara turned and ran. She went to a training room. By the time Alex reached her sister she had to cover her face as tiny pieces of what used to be a cement cinder block flew all around the room. Without stopping, Kara turned to the next block.

"Kara!" Alex called.

"Go away!" Kara yelled as she punched the concrete.

"Please talk to me Kara, I am your sister. Please let me be there for you?"

Kara sighed and, in an instant, her tough, angry look shrunk into a heart broken one. Kara sank to the floor as if she had no energy. She held her head in her hands, not wanting to see her sister's eyes.

"Surprise Alex, I love Lena. I have had a crush on her since the day I met her. I was afraid that I would lose her if I made any moves, besides, I assumed she was straight. Then last night, after I saved her, she kissed me."

Alex nodded. "And that is why you were hesitant about spending the night with her."

"I should never have stayed over. I took advantage of her, I can't forgive myself for that, and I don't expect her to ever forgive me either. Rao, I can't look at her face ever again!"

Alex knelt beside her sister. Kara had just come out to her. This was supposed to be a happy time for her, she wasn't supposed to be filled with guilt and shame over the person she loves. Alex remembered the hurt she felt when Maggie had rejected her, it was a painful memory. This was worse.

Kara's soft sobs began to fill the silence. Alex felt her heart break for her sister. Her mind raced, trying to find something to say that could comfort her sister. There was nothing. Instead she pulled Kara into her and wrapped her hands around her. Kara placed her head against Alex's chest and cried harder. Alex couldn't stop the tears that poured out of her eyes too. She held her sister as close as she could. It was all she could do.

After a few minutes, Kara let go of her sister. "Thank you, Alex. I love you. Can I get back to punching stuff now?"

Alex smiled. "Oh, what the heck, go for it, just be safe, okay?"

Kara rolled her eyes and helped her sister up. "I wish I could promise that everything is going to be okay, but I can promise that I will never stop loving you."

Alex hugged her sister one more time then hurried out of the room. She had work to do. She made her way to L-Corp. She needed to speak with Lena.

Lena looked disappointed when she saw Alex. "When Jess said Miss Danvers was here, I assumed it was Kara. Did you learn what I got drugged with yet?"

Alex looked around Lena's office. "Yeah we did. It wasn't anything we're used to seeing so it was just short of a miracle Brainy had seen it before, in the future."

"So, what is it? What did it do to me?"

"Do you feel any different than you felt last night?"

Lena raised an eyebrow. "Why are you avoiding this, Alex? No, I feel fine. I was dizzy last night but I felt better pretty soon and have been perfectly fine since."

"What about in the last 30 or so minutes? Anything emotionally different?"

"I don't think so, all I've felt is happiness to be honest. Pure joy. Because of Kara. I am guessing she told you, since you're being so weird."

"And your feelings for her, have they changed at all?"

Lena stood up. Alex didn't usually beat around the bush. Lena poured a glass of scotch and took a sip, feeling the burning sensation calm her nerves. "Now that I think about it, I do feel a change but it's not major. I think it's just my brain processing what happened with Kara. I am calming down, I guess. I love her."

Alex wondered for a second if the potion had not fully worn off. Lena didn't seem to notice anything and she still seemed pretty in love with Kara. She sighed. This was hard.

"I suppose I should tell you about what we've found."

"Please do," Lena was getting frustrated.

"Andrew McGee, how did you know him? How did he end up in your apartment?"

"I have known him since I moved here, he works for a corporate company that was going under. I helped the business out, it was one of the first things I did. I knew I would be able to call in a favour when the opportunity called for it. Their technology is ground breaking."

Lena moved over to the couch and Alex joined her. "The last few months he had been pursuing me and I had rejected him. Yesterday he came into my office and explained that he had a business idea that I would benefit from, he was very good at selling the idea, although he wouldn't tell me what it was, he asked that we discuss it over a private dinner. He was very cunning. I offered my apartment because I felt safer there."

"Dis you find out what his big business idea was?"

"We never got that far… I was hoping your interrogation and investigation would have uncovered more clues."

Alex smiled. "It did. Andrew is not who he says he is, we're not sure on his real name but we have found that he has little records past 5 years ago and none past 10. He is a warlock; he practises black magic. He gave you a potion last night that was likely to make you submissive to him. He had documents in his bag that if you had signed, you would have given away all of your rights to L-Corp. He would have been the new CEO."

Lena took another sip. She felt frustrated. Once, again she had failed to protect her business and herself. She was supposed to be smart. "Asshole," was the politest response Lena could get out.

"Your business is safe now, Lena."

Lena nodded. "I'm glad his potion didn't work. I think I'd better upgrade my security on all platforms and trust a little less."

"What about Kara?"

Lena smiled, "I was talking about business."

Alex bit her lip. "Right."

Lena laughed. "I wasn't planning on trusting anyone when I moved to National City. Then I met Kara Danvers. My heart is softer because of her. How much did she tell you about last night? Is your ulterior motive for being here to give me the shovel talk?"

Alex took in a deep breath. "I do need to talk to you about Kara and that potion…"

Lena raised both eyebrows now.

"The potion he gave you, made you submissive because it made you fall in love. It gave you a strong passion, a passion that would make you do anything for your love."

"But it didn't work. Right?"

"It did. But that person you were crazy in love with didn't want anything from you…"

"KARA!"

"The potion worked so that you fell in love with the first person you saw, we're guessing that you left immediately when you felt weird and the next person you saw was Kara."

Lena tried to take another sip but found her glass empty. She placed it on the small coffee table. She felt a mix of emotions.

"Is this a joke?"

Alex shook her head. "Lena, I need to know, as Kara's sister, do you feel different about her now? The potion was only supposed to last 12 hours."

"Where is she? Alex, where is Kara?"

"She's at the DEO."

"Well we have to get down there, now!"

Lena stood up.

"Lena, she feels terrible already, she didn't mean to, she thought that it was real. I can't imagine what you are feeling, but Kara is hurting too."

Lena pulled Alex off the couch. "Exactly, that's why we need to go! I couldn't understand why I felt so brave last night, I have been crushing on her for years and out of nowhere, last night I just felt so overwhelmed with love for her that I didn't hold back. I feel like I have come to my senses now, I don't feel like that passion is controlling me, but I am overjoyed that it happened. I love her so much. That will never change."

Alex didn't waste any more time. Within seconds they were out the door.
