I need my sister back

{RIGHT AFTER SUPERGIRL DISAPPEARED}

*SHORT*

Alex awoke with a start. Her eyes scanned around what appeared to be the medbay in the DEO. She winced as she shifted and a pain shot though her body. She could feel wires and tubes sticking out of her and the beeping of a monitor.

"J'onn? Kara? Anyone?"

J'onn ran in at the sound of her call. "Alex! You're awake. Oh thank god."

"J'onn, what happened? Where's Kara?"

"Do you... you don't remember?"

"I just remember the DEO was attacked and I got taken down. But that's all I remember..."

""Well after that, Kara disappeared. She got knocked into what appeared to be a wormhole. We haven't been able to find her anywhere. We've gotten in touch with Team Flash..."

"And?! Are they working on finding her??!"

"Alex, calm down. She's not on their earth. And she's not on any other nearby earths."

"Calm down?! How the hell am I supposed to be calm after that kind of information?!"

"Alex, please. We're trying as hard as we can."

"We'll you're not trying hard enough! I need my sister back!"

"Alex I know- do you hear that?"
Jonn sand Alex both froze and listened as a weird buzzing sounded and a blue orb appeared in front of them. Alex grabbed her gun from her holister and pointed it at it.

"Alex, I think," J'onn started before a red clad figure stepped though the orb. "It's Barry!"

Relived she lowered her gun and rushed over to the speedster. "Barry! Have you found her?"

"Not exactly," Barry grimaced as Alex's face fell. "But! But, we think we may have figure out why."

"Ok, why?"

"She's not on a different earth, she's in a different universe."
