Chapter I: Lonely.

"So, what're they like?" An excitable Winn asked Kara. She raised an eyebrow with a smirk at her best friend.

"What are who like?" She asked, struggling not to laugh. He was leaning so far across the matt black desk that she was half worried that he was going to fall off. Not that she'd let that happen, super speed came in handy for excitable fanboys.

"The techies! On Earth One. What are they like?" He asked insistently. Kara was momentarily taken aback, she had only just realised that she hadn't even mentioned Felicity and Cisco. How he knew that Barry had tech support she didn't know.

"I didn't even mention tech support. How did you know?" She asked him, smile evident both in her eyes and her voice.

"Please. There is no way that Barry Allen created that awesome suit! He's a genius and all, but that takes a whole different kind of smarts." The unspoken "my kind of smarts" hung in the air until Kara felt duty bound to feed his ego. He beamed at her.

"Seriously though, are they as cool as me and the DEO?" He asked, more seriously this time and Kara detected a hint of insecurity in his voice and his mannerisms.

"They're awesome, Felicity works with the Arrow and Cisco with Barry. She's some kind of genius hacker and Cisco is primarily a scientist. So no, they're not as awesome as you Winn, you happen to be both." He beamed at her. "You'd like them, Cisco especially, he's got your affinity for films and puns." Kara was smiling too now, imagining the two nerds interaction.

Throughout the day, Winn kept on bombarding her with questions to the point where Kara decided that she needed to patrol the city just to give herself a small brain break. As the twinkling lights of National City drifted bellow her Kara wondered about the why. She had expected him to be curious about her time in Barry's universe, and he very much had been, asking questions about the Arrow gang, the Legends and Flash's own team. Today was different, he was fixated on the people behind the keyboards, like himself she guessed. Perhaps he needed an ego boost? She discounted this as a possibility quickly, whilst Winn did occasionally need assuring that he was a valuable member of Team Supergirl today clearly went beyond that. As she circled L-Corp tower it came to her. Like Lena, Winn was lonely. It wasn't that he didn't have friends, the two of them were thick as thieves and he was well liked by Alex and even J'onn (which as Kara knew personally was no mean feat), but there wasn't anyone he could talk to about his projects and his love of computers. Initially he and Vasquez could be found hunched over a table, or a computer but it seemed he had far outstripped her ability.

She lowered herself onto Lena's balcony, if there was anyone who would understand and be able to help it was her. Besides, they hadn't talked since the Medusa incident and Kara didn't want her friend to think that she was angry. Lena didn't even turn around when she noticed Supergirl coming through the French windows.

"Hi Supergirl, come to arrest me I suppose." Her voice was weak, as if she'd been crying. Supergirl didn't know how to take it, Lena had always been so in command of her emotions.

"No! Lena, why would you think that, you saved my life!" She said, amazed, sure she had felt furious and hurt when it appeared that the youngest Luthor had betrayed her, but after seeing the damage that holding grudges could cause first hand (curtesy of Cisco and Barry) she had moved on.

"I lied to you Supergirl, you trusted me and I threw it back in your face. I should have trusted you, I'm sorry." She paused, voice cracking slightly. "You're the only person who has believed in me, except maybe Kara, since I've come to National City and I betrayed your trust. Can you forgive me?" Kara was heartbroken and her Supergirl façade shattered as she walked over to the CEO and wrapped her into a hug, letting the dark-haired woman sob into her cape.

"Shush, its ok. Of course, I forgive you Lena. I understand why you had to act in the way you did, and your mother would have got her hands on the compound she needed if you hadn't bluffed your way into her trust. You saved the life of my friends. Not to mention the fact that you're my friend too Lena, I'm not giving up on you. Promise." She felt the other woman nod almost imperceptibly on her shoulder and took a deep breath.

"Thank you." She coughed. "Is there anything I can help you with now that you're here?" She asked in a stronger voice now, the normal Lena coming back through.

"I have a friend."

"Really? Never would've expected that." Lena smiled and Supergirl beamed back.

"He's, how do I put it, like my eyes and ears when I'm in the field and he's really lonely because no one understands his work, and very few people care enough to even try. I went over to a parallel world yesterday, well, yesterday for you, to help out the Flash." At some point the pair had settled themselves on the sofa and were looking out across the city as the sun set.

"The guy with superspeed who vanished after two or three days?" She asked, nothing slipped past Lena.

"Yeah, him and some of his friends were having trouble with an alien invasion, and he knew that I got enough of them so asked for a hand. While I was there I met two people who were like W… my friend and he hasn't stopped asking me all about them all day, he seems really down." She finished. There was a pause as Lena thought for a moment, then her face lit up.

"Winn, it's Winn, isn't it? Your friend. The genius who nobody quite gets." She asked, already knowing the answer.

"What? Nooo, honestly Lena, what gave you that idea? … Fine, yes, its Winn. How'd you know?" She asked, remembering that she couldn't afford to get flustered as Supergirl, in case Lena drew the dots to the constantly floundering Kara Danvers. Lena gave a friendly smirk.

"He's the only person in the city besides myself with a high enough IQ and social skills to feel that way. Obvious really, to me anyway." She said, with a kind of confidence that some would have thought bordered on arrogance, but Kara knew differently.

"Is there anything I can do to cheer him up?" Kara asked, hopeful. Lena stared at the street lights as they flicked on to bring light to the darkening evening.

"How did the Flash contact you to ask for your help?" Lena asked. "If I'm allowed to know." She added quickly, not wanting to overstep her bounds.

"No, no, it's fine. He has a friend, one of the techs, Cisco who has the power to open portals to other universes. He left me a device to contact them if I needed there help or vice versa." Kara recounted.

"Well isn't it obvious?" When no answer from Supergirl was forthcoming Lena continued. "Introduce Winn to these people, invite them over on the pretext of a case you can't crack. Maybe hacking the Cadmus files, even Winn can't do that, I've been watching him try. Then he can meet people he can relate to, it'll be good for them too. He genuinely is one of the brightest people I've ever met." Lena was right, it was obvious. Kara was kicking herself that she hadn't thought of it herself, it was perfect, and if Felicity could help Winn hack Cadmus then it would be two birds with one stone.

"Thank you Lena, I really appreciate your help. So will Winn." She said genuinely.

"Anything for National City's hero Supergirl." Lena smiled. "Now go, help your techie." Kara laughed and launched herself from Lena's balcony, flying outside of the city limits. She used her X-ray vision to find a suitable spot and landed on an abandoned runway, the old tarmac cracking slightly under her slightly overdramatic landing. Reaching into her ear she sent a message to the DEO to tell them that she was going to be out of contact for a couple of hours and once she had received confirmation from Vasquez, Kara turned off her earpiece, she wanted this to be a surprise for Winn.

Reaching into a hidden pocket in her uniform, she pulled out the strange blue disc that Cisco had presented her with and pushed the central button.

"Uh, hey guys, its Kara. I was wondering if you could give me a hand with something." She asked, slightly awkwardly.

"Kara! Are you alright?! I can have Barry hear in 10 seconds, he's in Africa at the moment." Asked Cisco through the line, worry evident in his voice.

"No need, I was actually calling for you, well, you and Felicity. There's a database I need your help with, and a friend who I'd like you to meet… if you're free. Which you're probably not. Which is fine. Sorry." She gushed, feeling suddenly very nervous for no apparent reason.

"Whoa Kar, we're always free for you. Well, I am, and I'm sure Felicity is as well. I'll have to check." There was some static as Cisco changed the channel on his headset. A moment later Felicity's voice came through the device.

"Hey Kara, I'm free. I do love hacking unhackable databases, and any friend of yours is a friend of ours. We can be there in an hour if you want?"

"That'd be great, thanks guys. It means a lot." Kara replied before hanging up.

After an hour and ten minutes of carving Kryptonian symbols on a piece of rock because she was bored, the familiar blue whirlwind created by Cisco's Vibing appeared in front of her and the pair stepped out. Felicity wrapped Kara in a hug and Cisco gave her a high five. As she flew them back to base Kara explained both the situation about Cadmus and her worry about Winn and was not surprised to find that both were sympathetic, having been there themselves. She landed gracefully in front of the glass doors of the DEO, and after talking the guards (and a rather irate J'onn and Alex, both of whom were delighted to meet Cisco and Felicity, whilst telling Kara in no uncertain terms that she was to tell them next time she put out an interdimensional distress call) down, they walked towards the computer block.

"Hey Supergirl, hi random people I don't know." Called Winn in a friendly manner. Kara laughed.

"Winn, I'd like you to meet Felicity Smoak and Cisco Ramone. From Earth One."

"Oh. My. God." His draw dropped.

A/N: Hi Guys. I know I haven't posted in literally years. I'm not going to finish my first fic, I've lost my notes. Sorry if that disappoints any of you. But! I plan on making this a multi-chapter fic if there's any interest in it and if I can find the time around the boring, essential stuff in my life (hence the ending that allows for this to be a one-shot without TOOOOO much embarrassment). I'd love to hear any feedback and constructive criticism (or nice things, I like nice things) about this. Thanks to anyone who's actually bothered to read this. Oh, I don't own Supergirl, Flash, Arrow or Legends of Tomorrow. Sadly.
