DISCLAIMER: I do not own anything of the Flash or Supergirl.

I know I haven't uploaded in a while, but hopefully I'm not too rusty! Lol, I hope you enjoy this fanfic! Let me know in the comments below :)

There was panic all around her. Agents running about shouting, and typing loudly on the keyboards. Everyone always taking a second to comfort her and tell it was all going to be okay. But how did they know? They still haven't found her and it's been over 2 days. Two! Kara knew her sister was a survivor, but for how long could she survive?

"Kara, we're going to find her," Hank reassured her.

"Yeah, we've got every agent we have searching for her," Winn chimed in.

"You also said that yesterday," Kara said sighing. Kara took out her phone and dialed quickly.

"Who are you calling?" Mon-El asked. Kara just looked at him and rolled her eyes. Mon-El was still trying to get back to her. They had broken up just last week, even after the whole musical incident. And Kara was not about to let him back in.

"I'll answer your question when you answer mine about why you lied to me," Kara said angrily. She was his girlfriend. Girlfriend! And he had all the time in the world even before that to tell her his real identity.

Kara heard the familiar greeting of her friend.

"Hey, Kara Zor-El."

"Hey, listen I need you to come over, now," Kara said, her voice shaking, the tiniest bit.

"Are you okay?"

"Just, I-I need you to come over," Kara repeated, stuttering.

"I'm on my way."

Kara ended the call and saw her colleagues staring at her.

"Who'd you call?" Hank asked, curious about who was coming that was not already here.

Kara was about to answer when she felt the ground shake. They all grabbed what was nearest to them and hung on. Kara saw the signature breach open and she relaxed a little bit, knowing she now did have everyone helping.

She saw scarlet lightning race around the DEO and then land right in front of her.

"I like the old DEO, it had more toys," he said smirking.

Kara smiled and hugged Barry tightly. He returned it, not fearing the Kryptonian's strength.

He let go and asked, "Hey, are you okay, you sounded worried on the phone?"

"Alex is missing. She's been missing for 2 days and we have no leads," Kara said throwing her hands into the air, frustrated.

"We're gonna find her," Barry said, rubbing her arm.

Mon-El flinched as he touched her.

They walked over to the control center and Barry shook Hank's hand. "I'm glad you're here, Mr. Allen. How long are you going to stay?" Hank asked motioning to the black bag from where Barry entered.

"However long it takes to find her," Barry answered, giving Kara a reassuring look.

"Well, I look forward to getting to know you a little bit better. Ms. Danvers talks about you all the time," Hank said showing the tiniest hint of a smile.

Kara rolled her eyes and said, "Winn's in the other room, checking the monitors."

"Great," Barry said smiling.

Mon-El then took this time to fully introduce himself. "Hey, I'm Mon-El. I really didn't get a chance to know you last time we saw each other," he said standing a little closer to Kara, trying to show dominance.

"Oh, yeah. How are you guys doing? I remember Kara saying that she only for-..." Barry stopped short when he saw Kara's facial expression. "Nevermind."

"Get away from me," Kara said to Mon-El, walking away.

"Agent Schlott, someone's here to say hello," Hank said, breaking the silent awkwardness. Winn came into the room and dropped whatever he was fiddling with. "Barry!" Winn shouted excitedly. "Winn!" Barry shouted back. They high-fived and then Winn asked the obvious question. "What brings you to Earth...?"

"38. And I'm here to help find Alex," Barry said putting his right hand on Kara's shoulder. "So I'm guessing you already tried using her tracker," Barry said.

Kara smiled at his little habits when he's thinking. His scrunched eyebrows and the way he looks up at the ceiling and closes his eyes. "So, how did you guys find out when she went missing?" Barry asked, trying to get as much information as possible.

"She didn't come in for work and Maggie said that she told her she was going to Kara's, but she never showed up," Hank said.

"Maggie?" Barry asked, moving his hand so that his forearm was still resting on Kara's shoulder. "Her girlfriend," Mon-El said trying to see if he could get Barry to slip up. However, Barry just nodded and then asked, "Do we know what she was wearing?"

"No. I'll call Maggie and see if she can remember," Hank said.

"Barry," James said, entering the room.

"James, hey!" Barry said cheerfully.

James just nodded and Barry sighed, expecting that.

"Sir, we've found no evidence of chemical unbalance in the region," an agent said to Director Henshaw.

Kara bent the metal rod that she was holding on to. She walked out onto the area where she could look out, over the city.

"I got it," Barry said to Hank. He walked up, next to Kara and saw tears starting to flow from her eyes. "I mean how are we supposed to find her?!" Kara said starting to get angry. "How?! What if we never find her? What if I have to go on with the rest of my life, without my sister?!" Kara shouted.

Barry tried to pull her in for a hug, but she pushed him. He pulled her in with all of his strength and she gave up and let herself into his arms. "Kara, I'm not going to leave until we find your sister," Barry whispered into her ear. Kara wrapped her arms around his neck and thanked him. "I think I'm just going to go home," Kara said. Barry nodded and watched her as she flew off.
