Coming back from Barry and Iris's wedding the Danvers sisters get separated on their way home.

"Home sweet home." Kara smiled jumping out of the portal in the alley. She was surprised though as she'd usually find herself in her apartment.

"That's weird."

Noticing her sister was nowhere in sight the blonde started to feel uneasy. "Alex? Where are you?"

After searching the whole alley and finding no sign of Alex the feeling of unease started to turn into full blown panic as she imagined the worst possible scenarios of what could've happened to her sister. Taking a few deep breaths to calm herself she tried to listen for her sister's heartbeat, hoping she had somehow ended up in a different part of the city.

Closing her eyes she tried to suppress every other sound determined to hear the only one that mattered, sighing in relief when she heard a steady beating she'd recognize anywhere.

Changing into her suit she followed the familiar sound and as she was close enough she landed in the nearby bushes and changed back into her regular clothes.

"Alex!" Kara called running towards the brunette who, to her surprise seemed to be casually jogging, and hugged her tightly as she whispered. "I thought you got stuck in the portal."

"Umm sorry I think you've got the wrong person." Alex said confused as she pulled out of the hug.

"Don't tease me like that. I was really scared."

"Look, I probably have one of those faces but I'm definitely not who you're looking for." Alex said as she continued to jog away.

"Wait!" Kara called catching up with her. "Alex. I think something happened to you when we went though the portal. We need to get you to the DEO."

"The what?" Alex asked getting even more confused. "Wait, how do you know my name?"

"Because you're my sister."

"I don't have a sister."

"Just come with me please and I'll explain everything." Kara pleaded using her x-ray vision to check for any damage the older woman may have sustained. Noticing Alex didn't have the interdimensional extrapolator she had been given the blonde asked. "Where's the extrapolator? Did you lose it?"

"Okay. Are you feeling okay? Is there anyone I can call for you?"

Putting the pieces together Kara froze not knowing how to react. She was on a different Earth.

As Kara hesitated wondering what to say Alex's phone rang.

"Sorry, I need to go. I hope you find whoever you're looking for."

"Yeah, umm sorry for interrupting your exercise." Kara said before turning to walk away leaving Alex to look at her for a moment wondering why she looked so familiar.

Walking through the park Kara decided to check if anything on this Earth was the same as on Earth 38. But as she reached what used to be the DEO on her Earth there was nothing there, there was no alien bar, her apartment was occupied by someone else, there was no Supergirl, no Superman. There were no Aliens.

All she could hope for was that her sister got home safe.

Feeling lost and alone she wandered around the city trying to come up with a way to get back home. But she couldn't help but think what this Earth looked like with no Aliens. Letting her curiosity winn she flew to Midvale. Seeing Jeremiah and Eliza laughing as they sat on the porch made her heart swell and break at the same time as she thought about her Earth where he was gone.

She sat there watching the couple talking, spending the life together. The life they've got deprived of when she came to live with them. Enjoying their happiness she stayed there for a while before heading back to National City.

Having no where else to go she searched for her sister's heartbeat once again and followed it until she found herself near her apartment where she sat wishing she could find a way back home.
