"We don't have to do this tonight." Kara said softly, and sadly, "Or, you know... ever."
"No, no... it's been months. And I promised you." Alex pointed out reassuringly.
"But, do you want too?" Kara softly pushed, not the first time.
"Yes." Alex insisted, holding up a shot, "This is just a bit of liquid courage, that's all."
Kara wasn't so sure, as that was the third shot of liquid courage Alex had taken over the last half an hour, and the third bottle of beer. Alex was by no means a lightweight, but Kara didn't want to tell their friends about a relationship which meant so much to her when they might be too drunk to remember. More importantly she didn't want Alex to tell them when she was drunk out of her mind.
But she also didn't want to be the one to start the conversation, because she knew just how nervous Alex was about this. Kara was nervous too, but she was confident her friends would accept them. And even if they didn't right away, it didn't change anything. Not for her. She would still be Supergirl, and she would need the support of the DEO, and she was confident her friends would be professional. Most of all, nothing was taking Alex away from her.
Although the truly scary thing was that wasn't technically true, as Alex could take Alex away from her, if her adopted sister freaked out during telling people about them, or worse, their friends initially freaked out, which sent Alex down a downward spiral. Which Kara was very, very aware of, which was why she had agreed to do this in their favourite bar instead of in their home, where Alex could drink and they could both make a run for it if things got uncomfortable.
Not that it seemed to be helping Alex with her nervousness, even the less observant of their friends noticing that she seemed off for some reason, and Alex offering up increasingly lame excuses didn't help. Then, just as Kara thought Alex was going to seriously call it off, she took her hand underneath the table, took a deep breath, and began.
"You guys remember when Kara was under the influence of The Black Mercy?" Alex blurted out, interrupting a conversation between Winn and James.
"Erm, yeah?" Winn frowned, "Why?"
"Well..." Alex continued, briefly taking a sip of her beer, "You guys sent me into her brain, and I found myself on Krypton, and we were all there, just like it says in my report. But, I didn't mention it was also Kara's wedding."
"Why not?" James frowned.
"Presumably, she didn't think it was relevant." J'ohn shrugged.
"No, it's not that." Alex said softly.
"Was it because the groom was somebody really weird?" Winn guessed, before correctly guessing, "Or one of us?"
"There was no groom." Kara spoke up for the first time in a while.
"How can you have a wedding with no groom?" Winn laughed, as if the idea was absurd.
Which earned him a slap to the arm from Lucy, before she corrected him with a grin, "Because it was a girl, wasn't it?"
"Yeah." Kara admitted with a happy smile, finding it amusing how everyone seemed shocked except Lucy, and Alex of course.
"Was it me?" Lucy teased, "Because I'm flattered Kara, and I'd be lying if I said I hadn't thought about it, but I just wouldn't feel right leaving James for you."
"Hey!" James complained.
"What? I said I wouldn't do it?" Lucy pointed out.
"Yeah, out of obligation." James grumbled.
"Well, there might be other reasons." Lucy grinned.
"So if not Lucy, then who?" Winn asked cautiously, still rubbing his arm.
"Oh, was it your precious Cat Grant?" Lucy grinned.
"Erm, no." Kara frowned, "Why would it be."
"Well, you talk about her a lot." Alex pointed out.
"And look at her, and talk about her, and do every little thing she says." Lucy teased.
"I'm her assistant!" Kara pointed out.
"You're her favourite assistant." Lucy continued to tease.
"Yeah, she never says it, but she actually likes you. You can tell." Winn murmured, thinking back to previous interactions, "And you guys seem super close."
"I'm not dating my boss! I'm dating my sister!" Kara loudly exclaimed in frustration. Then realising what she just said, and the way everyone was looking at her, she quickly added, "Adopted! Adopted sister. Because you see I'm adopted, so it's not weird."
There was a long pause and then Lucy quipped, "Well, as long as it's not weird."
"It's not!" Kara protested.
"Saying it's not weird makes it weird." Lucy pointed out.
"No it doesn't." Kara whined petulantly.
"Yes it does." Winn argued, "That's your sister Kara! How could you do this?"
Alex had been busy downing her beer since Kara outed them, but this made her lose her temper, "Seriously Winn? Seriously? We're not even the same species! Just because my Mom told us we were sisters, it doesn't mean it was true. We've been more like best friends the past ten years, and while I didn't used to think of Kara as anything more than that, after that wedding, I can't not think of her that way. And what we have is good.
It's so, so good. And I will not be judged by someone whose last date turned into a super villain. Kara is amazing in so many ways, and I never thought I'd be lucky enough to be with someone like her, but now I am so, so happy. So do you think you could just be happy for us? Please?"
There was a long pause, perhaps even longer than the first, and then J'ohn got up and explained when Kara gave him an angry look, "I'm just going to get more drinks. I think we could all use them. But I'm happy for you both. I really am. Of course I expect both of you to fill out the appropriate paperwork. And attend a sexual harassment seminar."
"Yes Sir." Alex grumbled.
"A what?" Kara whined, before Alex nudged her, and she quickly corrected herself, "I mean, yes Sir."
Once he was gone Lucy spoke up, "You know what? I'm happy for you too."
"Thanks-" Kara began.
"Don't get me wrong." Lucy quickly added, "I still think it super weird, but you're right, you guys don't share blood, or anything."
