Letting Her In

Disclaimer: While I have not watched the full episode of the newest Supergirl premiere, I have seen clips. Though I am of the belief its cliché and predictable as Hell with what they are doing with Lena. Unless of course its a total fake out and hopefully is. And as seen in the summary for this fic, I'm accepting requests again and hopefully the Arrow/Flash tag will actually work now that I've messed with it.

Summary: As per Lena's words to her, Kara lets her friend in on one of the secrets she's been keeping.

"So, you know how you told me there can be no more secrets between us? And that you need to be let in on everything?" Kara 'Supergirl' Danvers asked of her best (so she hoped!) friend, Lena Luthor as they enjoyed some Chinese takeout in Kara's apartment.

Lena looked at her with raised eyebrows. "Would this be related to your Cousin's secret identity by any chance?" She questioned curiously.

"No, that's not my secret to tell and you know that."

"Right, fair enough. My apologies in that area as I got a little excited." Lied Lena convincingly.

Kara smiled at her, showing that all was well. "Tell me, what do you think when it comes to the idea of the Multiverse? Especially given that you are not only a CEO but a Scientist as well."

Of all the things she could have gone with, this is what she goes with? What on Earth is she trying to get at?

The CEO of L Corp just stared at Kara for a moment before speaking, making the Blonde Heroine a bit nervous. "Well… As much as I would love the idea of such a thing being reality instead of Science Fiction and theory, I try not to think too much on the idea." Answered Lena diplomatically.

Plus, even if it was a real thing, there was no telling what horrors there could be out in the Multiverse. Lena grew confused as her (supposed) best friend started to smile and then chuckle. "What? What is it?"

"Well…"

"Well what!? Out with it, girl! We don't have all day!"

Really, leading on and teasing just wasn't called for on their luncheon! Kara shot her a look as she continued to smile widely. "Okay, so I don't but you do given certain things." Grumbled the dark haired beauty, gaining a snicker from her friend in return.

The whole thing feeling like old times in a sense for Lena and trying not to feel too excited over that and having a small measure of success. "Well, I can promise you without a doubt that the Multiverse does in fact, exist."

"Is that so? Are you sure you weren't drugged or otherwise into believing this?" Lena asked doubtfully and got an eyeroll in return.

"I'm very sure I wasn't. Although, my Doppelganger and her allies from Earth-X did have me under Red Sun Radiation to try and get my heart last year."

"Earth-X? Your heart? What!?" Came Lena's confused and rising curiousity filled questions.

"Okay, so from what I've been told, there are 52 primary Earths in the Multiverse. Or at least as far as Cisco's been able to count anyway but there is a confirmed Earth-90. Now Earth-X is called as such because its said to be considered one of the worst Earths in existence and given some experiences myself, Alex, and a few friends of ours had with that one, well… I'd say it earns that description."

"And why is that exactly?"

I swear I will hurt her if she is having me on, damnit!

Kara frowned for a moment before answering. "Because… On Earth-X, that was where the Nazis won and my Doppelganger was part of its ruling class."

Despite herself, Lena found her eyebrows raising until they practically hit her hairline. "You… You can't be serious."

For the idea of the Nazis having won was too horrid an idea to contemplate for Lena. Unfortunately, the sad and serious look her friend gave her told her that she was being quite serious. "They crashed a wedding I was invited too and before all was said and done, cost someone my friends valued a great deal their life."

Though Kara never understood how Gideon on the Waverider wasn't able to save Professor Stein considering all the future technological advancements it had. It just never made any kind of sense to her whatsoever… "I'm… I'm sorry to hear that, Kara. I truly am. But… I don't recall any weddings you were invited too in the last year?" Said Lena in slight confusion.

Easily being able to tell that the other girl was being quite serious given the emotional feeling and waver to her voice. "Oh, that's because it was on Earth-1."

"Earth-1?"

"Yep. And to them, we're considered Earth-38. Earth-19 is virtually a no go from what I've been told because the inhabitants there don't tolerate travelers too and from other dimensions all that well."

"Hmm… I think we should be Earth-1."

Kara couldn't help the snort that escaped her. "Yeah, you'll have to take that up with Cisco."

"Cisco?"

"Cisco Ramon, native of Earth-1, an engineer, loves Pop Culture and using references from it, calls himself Vibe due to these blasts he can do, gets visions, and travels anywhere he wants on his Earth or to any other Earth." Promptly answered Kara.

Who wondered if her best friend was believing any of this but had a feeling it was possibly a struggle due to her being a Scientist. And would need definite proof before finally believing. "Interesting… Can his powers be replicated?"

As being able to transport one's self anywhere on Earth would be a very advantageous feat! "Not unless they have another Particle Accelerator explosion." Kara told her apologetically.

"A what? I, no, never mind as that can be for another time. I must admit, Kara, part of me wants to believe and then another part of me doesn't want too because of how… How ludicrous it sounds!"

"Well, at least its not because you're still unhappy with me for keeping a certain secret from you. Or… Is it?"

"It… There's a part of that, yes." Answered Lena reluctantly and truthfully, almost feeling a sense of guilt when she saw the look of guilt flash across Kara's face.

She watched as the other girl then pulled out some sort of metallic device from her pocket and pointed it at the open space in front of them. "Kara? What, what are you doing? What is that in your hand?"

"This is called an Extrapolator, Cisco made it and lets me take anyone I want with me to Earth-1."

Before Lena could say anything and or question that while feeling even more curious than before, Kara pressed something on the small object and to her shock, a blue portal opened up! "Oh, oh my." Breathed out Lena as she looked at the portal!

Kara just smiled and reached her hand out to her friend. "Ready to take the plunge and see how serious I'm being?"

Lena looked at her, a mix of curiousity and uncertainty raging within her as she did so. Finally, after a long moment, she hesitantly took the other girl's hand. Making Kara smile wider and together, the two went into the portal.

Author's Notes: Yes, yes I am horrible enough to leave this on a cliffhanger. Hopefully I did well in making Lena have a hard time believing in what she was being told by Kara for one reason or another.
