Kara was waiting anxiously for Caitlin to get the results back from the tests.

"Well?" Kara asked when Caitlin entered the base from her lab.

"You might want to sit down for this." Caitlin said.

"It's that bad?" Kara asked worriedly.

"More like shocking. Kara, according to these tests, you're perfectly healthy." Caitlin said.

"So then what's wrong with me?" Kara asked.

"I think that the problem is that you and Barry haven't been careful enough lately." Caitlin said with a smile.

"What do you mean?" Kara asked, though she was now starting to have a suspicion, but it didn't make any sense, it was just confusing.

"You're pregnant Kara." Caitlin said.

"What, that's not possible. At least not on this planet." Kara said.

"Well apparently it is possible because I've checked these test results three times and they're correct. You're pregnant Kara." Caitlin said, causing Kara to pause.

"Sorry. It's a lot to process. I always thought that as long as I had my powers on Earth, I wouldn't be able to get pregnant, so when I suddenly find out otherwise." Kara said.

"Yeah, I can see why you'd be surprised. So, how you gonna tell Barry?" Caitlin said.

"Right now. He's waiting in the other room." Kara said.

"You okay with Cisco and Felicity knowing to?" Caitlin asked.

"They're going to find out eventually." Kara said and Caitlin nodded.

"Well?" Barry asked as Caitlin and Kara exited the medbay.

"Everything is fine." Caitlin said.

"So what's the prognosis?" Cisco asked.

"What I'm about to tell you does not leave this room until I say otherwise." Kara said.

"Okay so what is it?" Barry asked.

"I'm pregnant." Kara said, shocking Barry for a moment before a huge grin shot across his face.

"Really." Barry asked.

"Yeah, is that okay with you?" Kara asked and Barry smiled.

"Yeah it is. I mean thought we'd be married at least a year before we started thinking about kids, but I've always wanted to be a dad." Barry said as he briefly thought of Nora.

"Good, because while I'm still trying to figure out how this happened, I am excited about it." Kara said with a smile as they kissed.

"Maybe you should talk to your dad. I mean he is a scientist and he's an expert with kryptonian science. He might be able to help figure out what happened." Cisco suggested.

"Good idea. Caitlin, is it still safe for me to fly?" Kara asked.

"I don't see why not. But then again, I don't really know anything about kryptonian pregnancies at the moment. Hopefully you're father can provide us with more information." Caitlin said and Kara nodded.

"I'll call my parents and let them know we're coming out to see them tomorrow." Kara said.

"Wait, aren't they coming in town for thanksgiving next week?" Cisco asked.

"I need answers now." Kara said and Cisco nodded.

The following day, Kara flew and Barry ran out to Washington DC.

"Kara, Barry, what a nice surprise." Alura said as she welcomed her daughter and son-in-law into their apartment.

"Hi mom." Kara said as she hugged her.

"Couldn't wait a week to see us?" Zor-El asked with a grin as he and Astra also greeted them.

"No, actually dad, I needed to talk to you about something." Kara said.

"What?" Zor-El asked.

"I'm pregnant." Kara revealed.

"That's both incredible and impossible." Alura said as she rushed up and hugged her daughter.

"That's why we came out here. We have no idea how this was possible, since Kara shouldn't be able to get pregnant on Earth, at least, not by a human." Barry said.

"But dad, we were hoping that you might have some idea how this is possible." Kara said and Zor-El thought about it for a moment.

"I suppose it could be possible." Zor-El said.

"What could be?" Kara asked.

"It's true that kryptonian women can't be impregnated by normal humans, but Barry isn't a normal human." Zor-El said.

"You think it might be because I'm a meta?" Barry asked.

"Yes, your DNA has been mutated beyond human standards and while you're not kryptonian or any kind of alien, it is possible that your speedster DNA is compatible enough with kryptonian DNA on this planet that you and Kara would be able to have kids the normal way. But this is all theoretical of course." Zor-El said.

"Still, it does explain a lot." Kara said and Barry nodded.

"If you'll let me take DNA samples from both of you, I can confirm it." Zor-El said and Kara and Barry both nodded.
