Disclaimer: I don't own Supergirl or the characters. This is written purely for fun.

A/N: This is set a couple of weeks after Alex in Wonderland. It is not trying to tie up any of the main ongoing plots in current season. It is going to be a little a dark, but will have a kind of happy-ish ending (for some characters at least).

"Do you want to meet up tonight?" Alex asked.

"No, I need to work." Kara said looking down at some notes.

"Are we okay?" Alex asked.

"Why wouldn't we be?" Kara asked looking up.

"Because since dad died you have been distant and I get that, after all I was a complete jerk."

"You were grieving." Kara pointed out going back to looking at her papers. "You had lost your dad, you had every right to grieve the way you want."

"I was still mean to you. I just want you to know that I didn't mean what I said."

"I know that." Kara said looking up from the papers again. "I am swamped at work at the moment. But I promise you this weekend we will have a sister's night."

"Okay." Alex said. "But don't work too hard."

"I won't I promise." Kara replied. "Don't you have a girlfriend to see?"

"Yes."

"Then go." Kara said ushering Alex out of her apartment.

"Fine." Alex conceded. But as she got to the front door she turned back. "Kara, I love you."

"I love you too." Kara said before shutting the door and going back to her papers.

Just when she thought she was making progress she heard a familiar noise.

"Lena?" She asked the empty room before changing into her Supergirl costume and flying out of her apartment.

"Have you heard from Kara?" Alex asked J'onn the following afternoon.

"Not today. Why?" J'onn asked.

"She's ignoring my calls."

"That doesn't sound like her." J'onn said looking up. "She could be busy."

"Maybe, but there is nothing Supergirl on the news." Alex replied before asking. "Did she say anything to you?"

"About what?" J'onn asked.

"Me."

"What about you?"

"What I said to her after dad died."

"You're entitled to grieve." J'onn said partially dodging the question.

"I'm just worried that this time I pushed her too far."

"Alex, you're her hero." J'onn pointed out. "Yes you hurt her, but she loves you, she always will."

"Then why is she being distant?"

"Perhaps she thinks you need space?"

"Is that what she said?" Alex asked.

"No. But Kara doesn't always open up. You know that." J'onn said. "If she hasn't responded by tomorrow, I'll talk to her."

"Thank you." Alex replied.

"In return I don't suppose you want to do this stake out tonight?" J'onn asked.

"Not unless you really want me to. I mean I could give up my date with Kelly-"

"It's fine." J'onn said standing. "I'm going to buy some food and head over there."

"Good luck." Alex said before picking up her phone.

"Hey Nia, it's Alex." Alex greeted as Nia answered her phone.

"Hi Alex."

"Have you seen Kara today?"

"No, but she and William have been working on a story that's kept them pretty busy." Nia replied. "Why? Is there a problem?"

"No, I guess not. I just can't get hold of her."

"If I see her I get her to call you." Nia replied.

"Thanks." Alex said hanging up before heading to Kara's apartment.

"J'onn." Kelly greeted entering his office at speed the next morning.

"Kelly? Is everything okay?"

"Is Alex here?"

"Not yet. Why?"

"She didn't come home last night and she isn't answering her phone."

"I thought you had a date?"

"We did. She cancelled. I was hoping she was working, but she she isn't answering my calls."

Frowning J'onn went to a computer and typed something in.

"She's at Kara's." J'onn said.

"Thank god. Wait, you track Alex?"

"Just her phone. She has a habit of getting into trouble." He pointed out grabbing his jacket. "Let's go over there and make sure everything is okay."

When J'onn and Kelly entered Kara's unlocked apartment they saw Alex sprawled in Kara's couch.

"Alex!" Kelly called hurrying to her side.

Slowly opening her eyes Alex asked confused. "Kel? What time is it?"

"Nine."

"Crap, I'm late for work." Alex said before sitting up and seeing J'onn before meekly adding. "Sorry."

"What are you doing here?" J'onn asked.

"I was worried about Kara, so came by. I guess I fell to sleep. Wait, is Kara here?"

"No." J'onn said causing Alex to rush round the apartment. "She didn't come home last night."

"Could she have stayed with William?" Kelly asked.

"Maybe. I just have a really bad feeling." Alex said. "Something is wrong." She added before pressing a button on her watch. After two minutes of nothing happening, apart from Kelly getting more confused J'onn said. "I'll call Brainy."

-00-

"Problem Dox?" Lex asked approaching Brainy.

"Mr Luthor." Brainy replied. "It appears that Supergirl is missing."

"That would explain why she didn't turn up to our meeting. I assume you have checked with the Martian?"

"No one has seen her since Thursday afternoon." Brainy said.

"That is most unlike her." Lex mused. "Can you look for radar tracks for the last couple of days?"

"That is what I am doing now." Brainy said. "The last radar return off Supergirl we had was Thursday evening at 21:12 hours." He then said. "I am correlating with news feeds and other signals of interests." He explained before going. "Hmm."

"Hmm what?" Lex asked.

"Lena's watch activated at 21:11."

"Lena's watch?" Lex asked.

"An emergency beacon that Lena could use if she were in trouble."

"Is Lena in trouble?" Lex asked.

"I have not heard from her. You?" Brainy said.

"No. But that is not unusual." Lex said. "And she did say she would be away for a few days. Something to do with a breakthrough. Are you able to see where the watch was activated from, or where Supergirl flew to?"

"She flew out of range of the radar after a few minutes." Brainy said. "But she was heading North East." He added as he type. "I am trying to triangulate Lena's signal. It appears that Supergirl was heading for it, but I can't pinpoint the origin."

"There." Lex said pointing to the map.

"What is it?" Brainy asked seeing nothing significant.

"We have a small research factory there." Lex said. "Send a team and find out what happened."

"Of course."

"Actually, you'll need my access codes. I'll come too."

-00-

"You have no authority to be here." Lex pointed out when J'onn and Alex landed in front of him. "This is private land."

"And my sister might be on it. So no matter what you are hiding, we will figure it out." Alex argued.

"I am as worried about Supergirl as you are." Lex said.

"I doubt that."

"Don't get me wrong, I still hate Kryptonians, but Supergirl is useful." He said. "While I can use her, why would I want her out of the way?" He asked.

"You're sick." Alex said as one of the Agents approached Lex.

"The team is ready sir. Do you want us to enter?"

"Yes." He said biting back a sarcastic comment. "Use code Alph Hotel Bravo 8 8 7." Lex instructed.

"Yes Sir." The Agent said returning to the entrance as he did so Lex explained to Alex and J'onn.

"It is the admin code. Before you get any ideas, I will change it when we're done."

"Sir, it isn't working." The Agent said returning.

"Did you put it in correctly?" Lex asked. Without waiting for an answer he moved to the console and tried and failed to open the doors. "So much for a new relationship of trust." He muttered. "Lena must have changed the codes. You'll have to blow the doors." He said backing away asking. "Lena, what are you up to?"

"You seem agitated." J'onn commented.

"Of course I am agitated. I am a control freak, and right now I am clearly not in control." Lex pointed out just as there was an explosion. "Not to mention Lena has just cost me tens of thousands of dollars worth of damages." He added as the DEO team entered the building.

"You don't seem concerned about Lena's safety." Alex said suspiciously.

"Lena can take care of herself. The fact that the codes have changed means she changed them. She wouldn't do that if she was in danger." Lex pointed out before asking. "Shall we?"

"What was this place used for?" J'onn asked as they moved through the corridors.

"Bio research." Lex said. "Ten years ago this facility was state of the art, but now it is obsolete, so the operation moved to National City."

"But you still keep the lab?" J'onn asked.

"The land is valuable." Lex shrugged before his attention was caught by something. "More valuable than I appreciated." He added as he approached some equipment. "And very valuable to Lena. This equipment is brand new." He pointed out. "Let's go to her private lab." He said turning off the main corridor. "I have to admit I'm impressed. I didn't think she'd be able to keep me in the dark, yet here we are." He said as they reached another door. This one protected by another security terminal.

He tried his access code and when it was rejected he turned to J'onn and said. "It appears that you are our only hope."

"In what way?"

"This door is designed to stop an explosion., we can't just blow it open. There is an emergency release on the inside, but obviously you need to be on the inside. That is where you come in."

"You want me to phase through the door?" J'onn asked.

"This sounds like a trap." Alex said.

"Cynicism looks good on you." Lex smiled. "It's your choice. If your sister is behind that door J'onn is the only way in."

"I'll do it." J'onn said approaching the door.

"Just so you know if he doesn't come back, I will kill you." Alex warned Lex.

"Just so you know we are on camera." Lex said pointing to the security devices. "You might not want to threaten me so publicly." He added.

Before Alex could respond the door opened.

"Told you. Perhaps you should actually trust me." Lex smiled, allowing Alex to step through the door first. As they entered Alex immediately saw the green glow.

"That's Kryptonite." She said increasing her speed as she searched for Kara.

"Do you smell that?" Lex asked crinkling his nose.

"Something burned down here." J'onn said searching each room.

Eventually he opened a door and stopped in his tracks.

"J'onn? What is it?" Alex asked, seeing his behaviour. When he didn't respond she tried to get past him. Eventually though she saw a glimpse of what was in the room and said. "No." Before pushing past J'onn.

"That explains the bad barbecue smell." Lex commented as she saw the charred bone fragments and a burnt cape. When J'onn turned to him, anger simmering in his eyes, Lex added. "Sorry, too soon?"
