AN: It may seem a little confusing or like there are pieces missing, but I'm trying to not reveal everything at once, so you guys can realize what's going on, around the same time as Kara. Would love to hear what you think about it!

The portal in front of her looked like an all consuming vortex, that Kara would have been a little scared to go through, if she hadn't already done it once before with Barry and Cisco. In truth, she couldn't wait to get back to Earth-38, to her own universe. She had been gone for a couple of days, and she was both curious and worried about whether or not the passing of time was the same on Earth-1, or if she would return home and find out she'd been gone for far longer.

At least she had had the time to leave a note for Alex before she'd left, explaining where she'd gone, so her sister wouldn't have a panic attack and think she'd been kidnapped. A smile lit up her face as she thought about what was waiting for her on the other side of the portal. Rao, she missed Alex and she couldn't wait to spend a girl's night with her, in front of the TV with a bunch of take-out food and an enormous amount of potstickers. She thought about Winn too, and how amazed he would be when she told him, that she had actually visited another world - it would blow his nerd brain.

And then her mind turned to someone else entirely; someone who had called the police on their own mother, and singlehandedly saved every alien on earth, including Kara. Yes, she really needed to talk to Lena, and thank her for all she had done. Before that though, she'd have to come up with a good explanation for why Kara Danvers had not visited the Luthor since the incident.

Turning around, she smiled at her new and old interdimensional friends, before she took a deep breath and entered the portal.

Interdimensional travel was weird to say the least; it felt like her entire being was folding in on itself and she couldn't breathe for several seconds. Then, just as quickly as it had started, the feeling stopped and air returned to her lungs. A gentle warmth hit her skin, and even before she opened her eyes, she could hear the familiar sounds of National City.

Breathing a sigh of relief, she took in the familiar surroundings of Earth-38. The city seemed just like she had left it; the streets were buzzing with life, and in the distance she saw Catco tower, glinting in the sun. The sight of it brought a smile to her lips, she was glad to see that the world hadn't gone under while she was gone, perhaps J'oon had even acted as Supergirl and kept up the peace.

As if the city knew she had just returned, she heard several cries for help close to where she was. Hovering above the town for a moment, she gathered her bearings and took off in the direction the screams called her to. Closing in on the scene, she heard the sound of a gun firing, and scanned the store below her to see what was going on. Inside the building she saw a person waving a gun around in front of six other people; customers who were being held at gunpoint.

Flying into the building, Kara managed to disarm the robber before he even knew what was going on. After securing the man to a chair for the police, she turned towards the six citizens she had saved, and x-rayed them to make sure none of them had been hurt. The people in front of her were surprisingly silent and most of them had their mouth open in shock - not that Kara wanted them to, but usually people cheered or thanked her. A couple of them had their phones out, and so before she took off, the blonde gave them a wave and a smile, before she flew out the way she came in.

Okay, Kara thought, she needed to figure out what to do; she hadn't brought her keys or phone to Earth-1, so both of them would be locked up in her apartment, where she couldn't get to them, unless she decided to break in. Almost flying past Catco, she decided to see James, who she had given a key to her apartment for emergencies.

She landed outside the office that had once been Cat Grant's, but was now her friend's. James wasn't in the room, but neither was anybody else so she quietly entered. The many TV's behind the desk told her that it was 13.17, so perhaps he was out for a late lunch. Sighing, Kara thought about going out to Winn, who'd probably know where their friend was, but she couldn't very well go out there dressed as Supergirl.

Glancing around the office, she saw a hoodie slung over one of the couches, that she assumed was James'. Thinking quickly, she grabbed it and pulled it over the S on her chest. Using the hair band that had been on her wrist for days, she tied her hair up in a ponytail that practically screamed Kara Danvers and looked at her reflection in the windows that surrounded the office.

It could work, she decided, the hoodie covered the most recognizable part of her Supergirl outfit, and the ponytail certainly helped, but her tights were still noticeably blue and very un-Kara Danvers-like. Perhaps her glasses would seal the deal, but she doubted James had any of those lying around.

Deciding that it wouldn't get better than that, she turned towards the door to track down Winn, but stopped in her tracks when she saw James there. "Kara!" he exclaimed, looking surprised to see her.

"James! You are not going to believe where I've been!" She started, happy to see her friend.

"I sure hope I do!" He said, sounding uncharacteristically angry, "You better have a good explanation for where you've been! Alex is seconds away from calling you in as missing, not to mention that L-"

"Oh, do you know where Alex is?" Kara interrupted him excitedly, looking forward to seeing her sister. "I think I left my phone and keys at my apartment before I left, so I can't call her."

James sighed and shook his head, "Yeah, they're in one of the conference rooms, I'll tell her and the missus that you're here." Kara frowned at her friends retreating back, what did he mean by the missus, but shook off her confusion and went back to looking out the windows.

The majority of National City's skyline could be seen from the office, and Kara found that her eyes were drawn to one building in particular, L-corp. She looked at the very top of the building, imagining Le-. Wait, hold on, she thought and took a closer look at the building's very top.

Why did the sign say Luthorcorp, instead of L-corp? Had Lena decided to change back the name of the company, while Kara had been away? She'd have to ask her friend about that the next time they met, she decided and moved away from the windows.

The sound of feet running in the hallway, made her look up just as none other than Lena Luthor barged through the office door. Without slowing down, the dark-haired woman ran straight towards Kara and threw herself against the superhero.

Kara blinked in surprise, feeling a little confused by the Luthor's show of affection. Sure, she had wanted to see Lena and thank her for all she had done, but she could only remember them ever having hugged twice before.

"Lena-" Kara started, trying to think of a polite way to ask her why she was even at Catco. Before she could come up with something though, the other woman had released her hold on her slightly and put their lips together in a kiss.

It was like getting shocked; it felt like every cell in the superhero was vibrating. But in reality Kara's entire body, including her lips, had completely frozen in place as if the action had somehow short-circuited her brain, and left her with a single thought: Lena Luther was kissing her. Like, her lips, were on Kara's.

They were just as quickly gone as Lena went back to hugging her so tightly, that even the superhero, whose body was practically made of steel, felt like the action was leaving her with bruises. Kara found that Lena's right cheek was pressed impossibly close to her own, and the scent of the other woman's lavender shampoo was all the superhero could focus on.

Seeing movement in the corner of her eye, Kara notices Alex standing there, and promptly turns completely red at the thought that her sister might have seen the kiss between her and the CEO.

Then Lena suddenly tears herself away from Kara so abruptly, that the blonde almost loses her balance. "Where have you been Kara?" The Luthor demands, her voice trembling slightly as if she's seconds away from crying. " Do. You. Have. Any. Idea. What. You've. Put. Me. Through?" Every word is followed by a light smack to Kara's shoulders.

The superhero looks towards her adoptive sister who has situated herself just behind the dark-haired woman, almost as if in support of her. Alex' facial expressions switch rapidly between looking pissed, amused and most of all relieved. There is too much happening all at once, and the blonde can feel the beginnings of a headache already.

Kara catches Lena's wrists gently in her hands, and just holds them there for a couple of seconds, while she tries to figure out what the hell is going on. Okay, she says to herself, Alex is obviously mad that I went away, I expected that. But why is Lena here? And why did she kiss me?

Rao, she wants to ask Lena that more than anything else, but that would just be a tad bit awkward with her sister right there, so instead the question that makes its' way out of her mouth is; "When did you rename L-corp?"

Alex and Lena share a worried look, and Kara releases the Luthor's hands as she moves to sit on one of the couches in the office.

"Kara are you alright?" Her sister asks and pulls her into a tight hug.

The blonde ignores the question and lowers her voice slightly, "How long have I been away?" she mumbles into her sister's shoulder.

Alex releases her from the hug, but keeps her hands on both of her arms, almost as if she knows that what she is going to say next is going to send the blonde's mind reeling.

"Well, Lena called me early last night when you didn't come home from work. She said you guys had plans, and so I got scared because you never just don't show up without saying something."

Kara nods in understanding, although half of her mind is still trying to comprehend what "Lena called me early last night when you didn't come home from work", means.

"We'd both called your phone all evening, until James found it at your desk. We stayed up all night, alternating between being here or at your place." A theory that's rapidly taking Kara's breath away is starting to make more and more sense. When Alex says "your place", does she mean "your" as in Kara's, or "your" as in Kara and a certain someone else's?

"So I've only been gone from yesterday evening till now?" The blonde asks, thinking that that's not really too bad.

It's clearly the wrong thing to say she realizes, as her sister's eyes narrow and she snaps out "Yeah, we've only been thinking you were dead for nineteen hours, no biggie!"

Kara's about to apologize, when Lena, who she hadn't even seen get up from the couch, asks her what the hell kind of pants she's wearing.

The question noticeably lightens up Alex' mood, and the redhead pinches Kara's tights between her fingers curiously. Her sister's reaction has just about confirmed her suspicions, and so the superhero asks a question she knows will change everything.

"Alex, do you know where my glasses are?"

Her sister doesn't actually say anything, she just gives her a confused look that sends Kara's heart plummeting. She gets her answer to more than one question from Lena, who grabs her right hand in both of hers and says;

"Honey, what glasses?"
