They needed some time together, Alex needed the rest and Kara just needed to take care of her.

red string 2

by XavAcid

After only a day in the med bay, Kara was able to bring Alex home. She promised Dr. Hamilton that she'd keep an eye on the agent, well, she actually promised to keep both eyes on her; she needed the both of them. They, especially, Kara knew how the older Danvers was when told to rest.

They still didn't know what was going on with her vision, all the tests came out clean, they compared all the tests to her records and everything was fine. But apparently she still saw the red string. Particularly, the one connecting their fingers together. Kara caught the older Danvers staring at their hands a couple of times already, and even though she said nothing, she knew that Alex was looking at the string.

She didn't know what to think of it. But she wasn't going to freak out, especially when Alex seemed so calm.

"Do you wanna take a nap first?"

"Hmm?"

"Or do you wanna get some lunch?"

Kara had taken a day off, it was a good thing that she had a lot of personal days saved up, and Lucy was pointing out to Ms. Grant that Kara was entitled to her day off. She knew she was going to pay for that later, but Alex was more important than a few snarks from her boss. Alex was the most important thing, and she was going to take care of her. Like Alex had always done for her so many times before.

"Lunch sounds good," a pause. "I know you must be hungry already."

Kara turned around after locking the door- Alex always stressed to her the importance of keeping it locked, so that no one could just barge in - and saw the brunette tossed her jacket over the back of the couch and then sinking into it.

Kara could tell that she was tired from all the poking the prodding she received before leaving. Alex was never a good patient, she remembered the few times that she needed to see the doctor, she would try to hide how sick she was, until she couldn't anymore. Even then Eliza still had to make her.

"Is there anything specific you want me to get?" She'd go to the other side of the planet to get whatever Alex wanted, absolutely anything.

Dark head tipped back to look at her with a tired smile. "Surprise me."

"Ok," blonde head bobbing one minute, the next she was gone and back in her signature red cape. "I'll be back in a few, you're gonna be ok here?" She was still worried.

Alex gave her a soft smile. "I'll be fine, Kara, just don't take too long."

"Alright, see you in a few."

Alex watched Supergirl darted out the window, the curtains fluttered in her wake, but a moment later she was back, and the brunette found herself being wrapped up in strong arms; she felt a kiss on her cheek.

Then her Kryptonian was off again.

Alex took a deep breath and decided that a shower was a good idea. She wasn't exactly in pain, not even a headache, but she was just tired, and decided that it must be the painkiller. Rolling her head to the side, she thought about the string. Even now she could see it, stretching out and away from the apartment. Out the window, the way Kara left.

Research, was her thought, she'd have to research this. But after a shower…

Kara decided on the older Danvers' comfort food, so she didn't have to go very far.

A food truck in Chicago it was.

She tried to be as quick as possible, but unless she was willing to use her Supergirl persona to bypass the line of people already waited for their food, she was going to have to wait for her turn. Besides, it would be unbecoming of Supergirl to use her fame like that, that would set a bad example.

After she paid, got the sandwiches, also extra large order of fries; she sped over to the waffle truck and got that, too. It did take her longer than she originally thought, though.

At least she didn't go halfway around the world.

Once everything was in hand, Kara changed into her Supersuit and took of. She really didn't want to leave Alex alone for too long.

"Alex, I got you a sandwich from your favorite food truck in-" Supergirl flew right into the window and went straight to the kitchen island and lay out all the food before she noticed that there was no response, she felt chill running down her spine for a second as she looked up to see if something was wrong. With a relief sigh, she went over to her sleeping human.

Kara stood there for a moment, Alex sat with her head leaned back against the back of the couch, there were dark circles under her eyes, and the Kryptonian felt bad about having to wake her up, but she needed to eat, they both did.

"Alex," Kara nudged her gently. "Hey, food's here."

She watched long lashes flutter and earthy brown eyes slowly opened, and smiled.

"You're back." Alex straightened up with a groan. Man, she needed a massage.

Kara winced at the sounds of Alex's joints popping as she stretching her back, they weren't loud or anything, but her super hearing was still better than any human even when she turned it down.

"Come on, let's eat, then you can take a nap, or watch movie, you can choose."

"I need a shower," the brunette murmured but accepted the sandwich in her hand. "Oh, my favorite."

"I know." Kara also nudged a bag of fries her way.

The Kryptonian blurred for a moment then back again in casual sweats and oversized t-shirt, she flopped down next to the older Danvers with her own sandwich in hand. She unwrapped her own sandwich, but didn't take a bite. Until Alex took a bite of her sandwich, only then that Kara did the same.

"Um.. this is good." Kara said with a mouthful, then she stuffed some more french fries into it.

"Kara…"

"What? I'm hungry."

Alex just looked fondly exasperated at her little Kryptonian with her cheeks puffed out like chipmunk.

With the time that she took to finish her sandwich, Kara ate three, and her extra extra large orders of french fries and whatever Alex didn't finish. They moved on to dessert, Kara picked up some sorbet that she kept frozen with her freeze breath until she put them in the freezer.

Alex took about two bites out of it before surrendered the rest to Kara and her puppy eye.

"Dork." Alex murmured and pushed at her shoulder,

"But I'm your dork." The blonde replied cheekily and allowed herself to go with the pushing hand then she happily ate the rest of the sorbet while Alex picked what they were going to watch next.

"I'm gonna go take a quick shower, ok?" The older Danvers said after a minute, "then we can just camp out here and watch movie."

"Ok," the Kryptonian grinned happily. There was nothing she loved more than spending time with Alex.

She watched her human got up with a touch more effort than usual, and she was reminded that Alex was exhausted. So, as soon as the older girl disappeared into the bathroom she went and gathered comforters and pillows so they could snuggle up together later.

Only then that she looked up to see what Alex picked for them to watch.

'Trollhunters?'

Maybe Alex was in the mood for some anime.

Alex was surprised when she came out of the bathroom- warm and comfortable from the hot shower and loose sweats - and found the couch pushed back and a nest made up with comforters and pillows on the floor in front of the TV, her little Kryptonian looking like an eager puppy. Big, golden, super-power puppy.

"So we can be comfortable." She said.

Alex just smiled went over to kiss her cheek.

She'd spend the time in the bathroom partly looking at the red string on her finger, seeing it disappeared out the door supposedly leading to the alien, like it did earlier when Kara went out.

She didn't know what it meant, and still had no idea where she could get the answer. Mentally, she'd made a list of where she could start to look. Maybe she could ask Alura AI, she might have some answer to offer. Just because Kara did not know what it was, it did not mean that it had nothing to do with Kryptonian.

She wasn't going to worry about it too much, so far it didn't really interrupt her life much, except being a bit of a distraction when she caught it from the corner of her eyes.

She'd tried to catch it in her hand, but couldn't. It just seemed to slip through her hand entirely.

Sinking into the fluffy comforter, she gave a long sigh.

"Trollhunters?" Kara gestured at the screen.

"Well, why not, it's Guillermo del Toro."

"Oh," Kara turned to look at the screen again. "I didn't know that." She pressed play.

Kara looked over to her human, Alex was deeply asleep. She'd expected that, with the way she her day was going. Actually, Alex held out longer than she thought, since she fell asleep after four episodes in, and they were not long episodes by any mean, being an anime an all.

She'd thought the older girl would be asleep by the second episode.

Not that it matter much, this was the reason why she set up the way she did, so they didn't have to move, the both of them were clean and comfortable.

So, Kara adjust Alex into a more comfortable position and she switched over to a different show, so that they could come back and watch Trollhunters again together. Alex seemed to enjoy it and probably identified with the protagonist a little.

Alex was younger than Jim when she had to take the responsibilities beyond someone so young should. But she did it, and all things considered she practically raised Kara to be who she was.

She very much doubted that Kal El could've done it. He was an absentee cousin, always saying that he was too busy to raise a twelve year old, but Alex was only a year older than her, and she took care of a strange alien girl with a single minded determination like she did everything else.

Now Kara just wanted to take care of her. Something that did not happen very often, Alex was always the older sister, always the caretaker.

From beside her, a sleeping brunette shifted her position to her side, an arm thrown across her belly, with Kara being half sitting with her back resting against the couch. Alex looked relax and young in her sleep.

With her left arm across her body, the Kryptonian just couldn't help thinking about what her older sister was saying earlier. Red string.

She still couldn't see it, even with her x-ray vision pushed to the limit, which allowed her to see a whole hoard of things: several old fractures and scars, she could even see AF signal, and yet she could not see this red string Alex spoke of.

Maybe she could ask her mom's AI, or she could start with the alien they captured. She hoped that it was nothing that could come back and haunt them later, or she'd do something drastic.

Snuggling down, Kara pulled her precious human close.
