It should hardly surprise you to hear that Lena and Kara's sixth date almost two months later was also rudely cut short. They had finished their meal, and were just crossing the road to head to a bar, when a car came speeding down the street. Kara caught a glimpse of the driver – unconscious – before speeding to save a small child from the path of the car, changing as she moved.

She had assumed that Lena would be safe – they were nowhere near the path of the oncoming vehicle – but what she hadn't counted on was the physics that followed it's collision with a stationary car.

The second car was jolted forward, and arced around as though it were drifting, smashing Lena into the side of another vehicle.

It bounced back away from her after the initial impact, but she fell to the floor between the cars. Kara was busy saving other pedestrians from cars that were actually being driven, which were now gradually becoming involved in the crash site.

Lena lay on the hard tarmac, drifting in and out of consciousness. Moving her head made her feel dizzy, but the pain in her leg was excruciating and she had to see what happened.

As soon as she looked down, she regretted it. She had a compound fracture. (If you don't know what that is, do not google it. A compound fracture is where your bone breaks so severely that there is bone sticking out of your flesh. Do not google it.) As the screaming around her started to die down, she knew that Kara had done her job well, but she was hidden from view here.

Supergirl had stopped any more cars joining the pile up, gotten all the injured to safety and flew up into the air. She could hear sirens in the distance, and realised she couldn't see Lena.

She used her x-ray vision, and rushed as humanly as possible over to where her girlfriend was lying on the cold ground.

"Lena, Lena, look at me," she said quietly, breathless as she tilted Lena's head to face her.

The paramedics were just arriving, and another car crash could be heard in the distance. Kara looked up in it's direction, and Lena weakly pushed her away.

"Go," she managed. "Go help, I'll be fine," she assured Kara, and felt her hand brush her cheek before a gust of wind told her Kara had flown away.

Next moment, a man had knelt down beside her, dropping his medical bag by his side. "Miss Luthor, my name is David, can you hear me?" He asked calmly. She nodded minutely. "I'm gonna give you something for the pain, okay? It might make you sleep." Lena managed to open her eyes and look up at him. He didn't wait for her consent before he took a small needle from his bag and injected the fluid into her upper arm. Something wasn't right.

"Wh-" Lena began, meaning to voice her confusion, but her arm began to tingle slightly. Instead of starting to drift off to sleep like the man had said she might, it was like her senses were cranked up to eleven. She could smell blood, burning rubber, singed cloth, hot metal. The scents hit the back of her throat and it was like she could taste it.

She could hear Kara fighting to stop the second pile up, hear her breathing and her heart rate – she knew it to be Kara's from the amount of time they'd spent together – hear her grunt as she used her weight to stop another moving car.

She could feel every miniscule dent in the tarmac underneath her, she could feel every bump through the fabric of her dress. She thought she could even hear the bacteria that lived in the cracks, protesting against her weight upon them.

She felt coherent, now. "What did you do to me?" She asked, her chest heaving and her body beginning to convulse slightly.

The paramedic looked exremely confused at her reaction, and all of a sudden the pain throughout her body was excruciating. Her ribcage felt like it was on fire, her face burning, her leg feeling like it was about to spark a blaze with the gasoline from the two cars either side of her.

A scream tore itself from her throat, louder and stronger than any noise she'd made in her life. She felt like it was ripping the pain away, clawing it from inside her body. She pounded the ground with her fist as J'onn landed in front of her.

He scooped her up carefully, Lena's nails digging deeply into the chest of his armour, ripping it. Her screams turned to crying as they flew upward. Her head hung over his arm, and she watched as DEO agents surrounded the paramedic who had attended to her, arresting him and bundling him into one of their vans.

By the time J'onn landed at the DEO, Lena was out cold.

But there wasn't a blemish on her.

The cuts and scrapes on her head were no longer there, her ribcage no longer bruised, and her left leg was whole again.

When Kara finally finished coping with the destruction downtown, the DEO was her first and only port of call. She headed straight for the medical bay, and was confused to see Lena resting on one of the beds usually reserved for aliens.

Lena was in a seat by her side, holding tight to one of Lena's hands, her tablet on her lap as she used it with the other.

Kara stood at the foot of Lena's bay, looking over her carefully, her brows furrowed together.

"Hey," Alex said quietly, not wanting to wake Lena. "She's okay."

Kara shook her head in disagreement. "No. This isn't right. When I saw her... Alex, her bone was sheared in two!" she whispered exasperatedly. "She was so badly hurt, how is she suddenly fine again? I've only been away from her for like, half an hour."

Alex nodded while Kara spoke, and reached her other hand out for her little sister. "I know, J'onn said. We're running tests right now.

Kara's eyes watered slightly, unable to shake Lena's desperate screams from her head. The moment she heard them, she made to leave the second crash site, but J'onn had insisted she stay while he went to help Lena.

"Agent Danvers?" a technician asked quietly from the door, hugging her clipboard to her chest.

Alex took her hand back from Lena's, rubbed Kara's arm as she passed her, and huddled close to the young woman at the door.

Kara moved slowly towards Lena's head, unable to believe that this pristine woman had been in such a terrible state just a short while ago. She stroked Lena's cheek with the back of her hand, and stood staring down at her.

She caught Alex's conversation behind her.

"You're absolutely sure?" her sister asked.

"We ran both of them five times. There's absolutely no mistake," the attendant assured her.

Kara spun around. "What is it?" They looked hesitant to divulge the information. "Tell me, now," she demanded.

Alex shook her head. "There's one more test I need to run," she said simply. "Sheila, can you tell J'onn about this, please? I'll be back in a few."

She gave Kara a reassuring look as she left. Alex may be immune to Kara's piercing glare, but that didn't mean the technician was... Kara tried it. The technician was, in fact, immune to Kara's glare. She also walked away, leaving Kara and Lena alone.

When she returned almost ten minutes later, her cheeks were a rosy red and she seemed almost embarrassed.

Kara stood up, one hand linked with Lena's on the hospital bed.

"Kara," Alex started, sounding almost sad.

"Is she dying?" Kara asked immediately. Alex's tone was the same as when she had told Kara that Jeremiah had died.

Alex shook her head. "No, but, uh... You should sit down." Kara didn't move. "Sit down, Kara."

This time, the younger sister obliged. Alex came and took the seat next to her, taking Kara's hand in both of hers.

"First, I need you to input protocol two-one-seven on that panel," she asked quietly.

Kara's eyes narrowed. "But that's for-"

"Kara, please."

The blonde did as she was asked, and typed in the relevant codes. Panels unfolded from the sides of the bed, and when they turned on they shone light down at Lena, light that mimicked Earth's yellow sun. This was the equipment used when Kara or Clark had a solar flare, and needed to recharge their powers.

Alex started to rub her thumb back and forth across the back of Kara's hand.

"Please don't talk back, okay? Please just let me say this all together." She waited for Kara's nod, and let out a deep sigh. "When Lena got here, she was already uninjured. It took us a while, but we finally got to take some blood.

"It came back just before you got here, and the team ran it again and again to be sure." She hesitated here, refusing to make eye contact with Kara, who looked like the whole world was about to be taken away from her.

"First, Sheila noticed traces of Kryptonian DNA in Lena's bloodwork. That's why she kept running it. And then, she decided to do another test," she'd held her hand up to stop Kara from speaking. "And when it was positive, she ran that again too."

She huffed greatly, and finally looked up at Kara. The blonde was clueless to everything Alex was saying, all she'd picked up on was the potential Kryptonian DNA.

"Kara..." Alex huffed again. "Lena is pregnant. With a half-Kryptonian baby."

Silence. Absolute silence. Kara just stared at her older sister in shock, and she thought she detected a hint of horror.

It was another five minutes before Kara finally spoke, turning to look at Lena as she did so. "How is that even possible?"

Alex's cheeks turned red again, and Kara even felt her sister's hands warm up around hers.

"That was my last test. I went and asked Alura," she said gently. Kara looked at her again. "She told me about how it's possible. And she gave me a much further insight into your sex life than I needed," she smiled awkwardly at the end of this sentence, and Kara blushed also.

"What.. What was it that had to happen...?" Kara asked quietly.

Alex cleared her throat awkwardly. "Well, the uh, the stuff I told you to buy a few years ago. You needed that. With uh," she cleared her throat again. "With you... being... the uh, recipient first," they both blushed more. "And then Lena, right after..."

They were quiet again for a while. "So it's... It's definitely mine?" Kara asked, so quietly Alex wasn't sure she'd even heard her.

"Yeah. Come on, you really don't think she'd cheat on you?"

Kara shook her head. "No, but you don't know what happened before we got together..."

Alex nodded in agreement. "Yeah, but we calculated conception to be, uh, the night we all went to pride."

Kara took her hand from Alex's grasp, stood up, and lay it on Lena's lower stomach.

"We don't know anything about Human-Kryptonian pregnancies, so this is going to be a bumpy road... But for humans, you can normally hear the baby's heartbeat after eight weeks."

Kara nodded, and when she spoke Alex could hear that she was crying. "I can, I can hear it."

"We think that the baby protected her," Alex said gently. "When David The Paramedic injected her with an anaesthetic, the baby rejected it. It kickstarted it's powers, healed her injuries, and it would have hurt, hence the screaming,"

She trailed off when Lena started to stir. Kara squeezed her hand gently, Lena staring up at the ceiling.

"Hey," Kara sighed. Lena flinched as she spoke, her free hand moving up to cover her ear. "Lena?" She pulled her other hand free from Kara's hold, and up to her other ear to cover that, too.

"We thought this might happen," Alex said as quietly as possible. She slipped a glasses case from her pocket, took out the specs and slipped them gently over Lena's eyes. She calmed almost immediately. "I'll leave you guys to it." With that, Alex rubbed Kara's arm again and left the room.

Kara helped Lena sit up, and propped her up against the headboard.

"Why am I okay?" Lena asked quietly, leaning into Kara's touch.

Kara sighed, now understanding how Alex felt minutes before. "There's no easy way to say this, Lena." Her love looked at her in confusion, and she looked so adorable that Kara couldn't stop herself from kissing her sweetly.

"Um," she muttered, stroking Lena's cheek. "We're, uh," she gulped.

"Kara, just tell me."

She looked into Lena's eyes, and smiled awkwardly. She was happy about this, so happy about this. Growing up, all she wanted was her own family to love and cherish and care for. But this was Lena's issue too, and if it was going to be a problem then she would respect any decision Lena made.

"We're having a baby," she finally blurted.
