A/N: So... as most of my stories go, I kinda just have this idea and let it run in whatever direction it wants to go in. I love the feedback I'm getting back from you guys, so thanks a bunch for your thoughts! The next chapter will be longer, I promise!

Chapter 4: Inner Thoughts

Kara wasted no time in getting back to her apartment to read Lena's letter. She rushed through her window and took note of the dust that swirled around her before it settled. Ever since Lena had been staying at the DEO, Kara had put her civilian life on hold, at least when it came to her apartment. As Supergirl, she could stay up late with the overworked CEO and listen to Lena delegate in several languages depending on her clientele. The brunette continued to amaze her daily, and Kara wondered if she'd ever stop feeling impressed by the woman's brilliance.

As she threw herself on the bed, she pulled the letter to her nose and sighed at the wonderful scent associated with Lena. Not too sweet, not too musky… she was perfect. Kara felt extremely giddy as she giggled and eagerly opened the letter.

Dear Kara,

Thank you for the flowers, and I promise this plant will live a much longer and fuller life. I'm not sure what Supergirl told you, but it was never my intention to kill our first plant; I am more than sorry for letting it die. In other news, I honestly can't wait until I'm able to see you again. (Lena's words made her warm inside, and she felt a certain whoosh in the base of her stomach.) Lunch isn't quite the same without you, and even though I'm in good company, I really miss our movie nights. So far, all I've watched are a bunch of Star Trek reruns because of one of my colleague's rampant obsession with it. (Kara chuckled at Lena's mention of Winn). I promise you can pick a rom-com when I get back; I even promise not to make any snarky comments about the level of cheesiness.

I'm sorry if my absence has made me seem distant, and I can't even say for sure when I'll be able to see you again, but I'm working as efficiently as I can. Just the thought of reuniting with you makes me smile… see what happens when you become my only friend in National City. I'm at the point where I just can't live without you. When I'm done with my work here, there is something I'd like to discuss with you, if you don't mind.

Until then, I'll continue to miss you and keep our plant alive.

Love,

Lena

Kara clutched the letter to her chest and felt like yipping in joy. Lena had called the plant 'our' plant, and she missed her! Her smile faltered when she thought about how empty her life would be if she actually couldn't see Lena for a long period of time. She felt selfish keeping her identity a secret and letting Lena believe her best friend wasn't always two feet away, but she wasn't ready to make the jump just yet. Instead, she decided to be rational about the way things were unfolding between her and Lena, and wrote a letter back.

The next morning when Alex stopped by for coffee and kolaches, Kara smiled and offered her the letter.

"What's this? It better be a thank you card for me, after that shenanigans you pulled with the flowers and plant…" Alex muttered as she snatched the envelope out of Kara's hand.

"Actually it's for-" Kara started but was interrupted by a groan.

"Lena? You can't be serious," Alex threw her hands in the air. "Why can't "Supergirl" take it to her?" The agent used air quotes around the superheroes name as she handed back the letter to her sister.

"No, she already has weird ideas in her head about my relationship to Supergirl." Kara whined.

Alex raised her brow, "wait, does she suspect your identity…"

"No, not quite… she thinks I'm… that me and Supergirl are," Kara searched for the mildest way to phrase it.

Alex laughed as she caught on to Kara's embarrassment. "She thinks you and the "girl of steel" are sleeping together?" She broke into a fit of laughter and stuffed the letter on the inside of her jacket. "If only she knew how literal that statement was."

Kara rolled her eyes as her sister continued to joke at her expense.

"You know… this can't last forever right?" Alex glanced seriously at Kara.

"What do you mean?"

"This whole thing with Lena," Alex frowned, "you can't continue to be two people to someone who's supposed to love all of you."

Kara nodded but said nothing. She knew Alex was right. She loved Lena for everything that she stood for; through both Supergirl and Kara Danvers' eyes, Lena was beautiful. She loved the way the Luthor refused to be defined by the world around her; how Lena elevated herself by helping those around her. Her newfound abilities to instantly toast bread and save Kara from gigantic, stone boulders were only added benefits. Hopefully Lena would also find all of Kara-Kara Zor-El-loveable.

Lena hummed to herself as she poured a generous amount of water into the leafy, green plant Kara had given her. She was determined to have this plant thriving by the time Kara was able to see it again. She set it by the window and turned when someone knocked on her door.

"Come in," Lena called out while still focusing her attention on the plant.

The door creaked open and in came a cheery superhero. "What are you up to?" Kara asked.

"Just watering my plant," Lena answered.

"You mean our plant."

Lena's brow rose as she turned to look at Supergirl. "What do you mean by that?" Lena stared hard at the Kryptonian who looked like a deer caught in the headlights.

"By what?" Kara gulped.

"This is the plant Kara gave me, but you said 'our' plant." Lena explained.

"What?" Kara fretted; she was totally sure she had said that in her head. "I didn't say that," she protested.

"There's only one possible explanation for this," Lena pursed her lips and crossed her arms.

"Lena, I can assure you, I didn't-" Kara started.

"You're seeing her, aren't you?" Lena accused.

"Seeing her?"

"Kara." Lena clarified with an icy tone.

Kara's eyes widened as she realized what Lena was thinking. "Lena, no… I can promise you one million times over that I am not seeing Kara Danvers."

Lena walked up to the Kryptonian and noticed how she glanced down to the floor. Kara felt the need to step back, but no matter how far she went, the Luthor pressed forward until the blonde stumbled back against the wall.

"Why should I believe you?" Lena asked as she cornered the superhero.

"Because I… well, you see I," Kara stuttered to find the right words to get Lena back on track with Supergirl. "I like somebody else."

Lena faltered as the Super's eyes locked with hers. She had looked into the girl of steel's eyes plenty of times, and always found them to be comfortable, even familiar sometimes. At this moment, however, they held so much more than that. The Luthor found herself leaning in as if the Super was emitting her own gravity field.

"If not Kara, who?" Lena murmured as she felt the Kryptonian's hands rest on her hips.

Her lips were close, her body flushed against her chiseled six pack, as Kara whispered, "you."

Lena's eyes widened and for a moment she was sure her lips had brushed against Supergirl's, but as soon as the contact sent a tingle through her, she pulled away.

She shook her head and spoke softly, "I'm sorry… I can't. I'm in love with Kara."

Kara's heart soared even as Lena pulled further away from her. It soared because Lena Luthor had just professed to being in love with her; the girl of her dreams felt the same way, and she couldn't think of a happier thing. And then her heart came crashing down at the unfairness of it all. Lena was honest and forward with Supergirl and Kara alike, and Kara was still hiding. No doubt Lena would feel played and even wronged by Kara's secrecy, and moments like this would just further serve to discredit her in Lena's eyes.

"I'm sorry," Kara's voice cracked as she slipped away from the wall and fidgeted with her hands. "I should go."

Later that day, Lena lay on her bed and held a letter up towards the ceiling; it was from Kara. Alex had rolled her eyes upon handing her the letter, and then muttered something about this being the 21st century and only romantic nerds still wrote letters, but that didn't stop Lena from grinning like an idiot. Her heart rushed with emotions, but the closer she got to her room, the more conflicted she began to feel.

Supergirl had almost kissed her today. Lena shook her head… she had almost kissed Supergirl today. The Super's comment on the plant had taken her off guard, and the actions after even more so. Feeling the Kryptonian's hands rest firmly on her hips had made her legs weak, and feeling her cool breath on her lips made Lena want to close the gap. If it hadn't been for that familiar scent, Kara's scent, she would have been lost to her innate desires. She couldn't deny her sexual attraction to both Supergirl and Kara, and her dreams were starting to combine the two, which made her feel hot and ashamed at the same time.

Still it made absolutely no sense why Supergirl would call it 'our' plant, and why the hell did she even smell like Kara? Lena's jealousy boiled even as she held the reporter's letter firmly in her hands. Kara had never mentioned being interested in the girl of steel, but she did always seem somewhat nervous and defensive when the Kryptonian came up. Lena's heart juggled with possibilities. She sighed, realizing she would get nowhere until she read Kara's letter.

Dear Lena,

I have no doubt that this plant will be the one that makes it. Also you're going to regret letting me pick a rom-com because it's going to be the cheesiest, sappiest, love story of all time. Remember that one time when you came over for movie night, we drank a bunch of alcohol, you ended up confessing that you didn't like rom-coms because you didn't know if love was real, and then I just started bawling…. it's going to be one of those nights. My job is to convert you to a staunch believer in love.

There's actually something I'd like to talk to you about too, but I'd rather say it in person than just have you read it off of this letter.

Love,

Kara

It was a short letter, but it left Lena feeling a multitude of emotions. Kara was by far the most adorable person Lena knew, and her heart swelled at the thought of watching a rom-com with the bubbly blonde. The end of Kara's letter caused her to take in a sharp inhale of breath, but the easy going nature of the first half of Kara's sentiments put her at ease.

She rolled her shoulders and heard a couple of cracks and pops. Today's training had been grueling, but thankfully Supergirl was on the ball today and Lena didn't have to worry about her getting pummeled by random flying objects. In fact, it was Lena who was finding it hard to concentrate next to the indestructible woman who had almost locked lips with her. She wasn't sure what she was feeling towards her, but it was enough to throw off her focus.

"Lena," a soft voice beckoned her from her bed. "It's me… Supergirl. Winn asked if I could come get you. He's found something."

Lena jumped off her bed and rushed towards the door.

"What did you say?"

"Winn, it seems he's found something related to your powers." Kara was speaking to Lena, but her eyes went everywhere else. She was partially afraid that she might try to kiss the Luthor if she stared at her for too long.

When Kara finally got over her impulsive nature she looked up, but Lena was already striding past her and heading towards the main communication room. Kara trailed behind and couldn't help her gaze from wandering. Lena had been wearing sweats instead of her pencil skirts, but somehow her shape was always present. As they neared Winn's desk, Kara absentmindedly licked her lips and thought about what it might feel like to…

"Excuse me, what did you just say?" Lena whipped around and looked at the superhero.

"I… I didn't say anything," Kara fretted as her face began to heat up. There's no way she had said what she was thinking outloud.

"I'm not deaf and neither is Winn," Lena muttered as she crossed her arms, but upon glancing towards Winn, she noted his confused expression. Her confidence faltered and she shook her head. She drew closer to Supergirl and whispered in her ear what she thought she heard.

Kara's heart raced as Lena's breath tickled her ear, but what really had her heart going was Lena's ability to mimic her exact thoughts. Kara furiously blushed, and as Lena pulled back she didn't know what to do. If she admitted to Lena having telepathic powers, it would be the akin to admitting she had been looking at her butt.

"Oh would you look at that," Kara pointed to the huge screen that displayed a map of National City, "crime, crime all over the place, I gotta go!"

Supergirl whooshed out of there before Lena could force her to admit to her rather inappropriate comments. Winn made a strange face as Lena turned back to look at him.

"Ooook what was that about?" Winn hadn't seen Kara act like that since meeting James.

"I think… I think I can hear her thoughts," Lena theorized.

"No way, not even J'onn can do that! I'll go ahead and add that to your list of abilities," Winn chirped excitedly and then asked in a smug tone, "so, uh, what was she thinking?"

"Didn't you have something important to share with me?" She nudged the curious man.

"Oh right, so I haven't found a direct link to your mother yet, but what's interesting is your father's collection of Arthurian lore."

"Arthurian lore? Seriously… what's that have to do with all this?" Lena's eyes glowed yellow and Winn's tie came up to slap him.

"Hey! Let me get to the good part!" Winn fought his tie back down. "His collection isn't normal. It's full of actual lineage charts and historical anthologies; it isn't your run of the mill knights' tales of "The Once and Future King." So I looked into those further and look... " Winn finished and pointed to a page

Lena scanned the page and focused on the name etched at the very bottom of the strange family tree. It was her name, and above it a scratched out mark… the spot where her mother's name would be.

"You're a witch."
