A/N: This is set sometime after the events of the 'Girl of Steel'

"Hey Lena." Kara said walking into Lena's office. "Ms Grant? What are you doing here?"

"Well I heard there was a special event involving a Luther, a Super and children. It seemed a too interesting opportunity to miss. I mean you know what I always say about children?"

"They are more potent than biological weapons and like weapons of mass destruction should be locked away." Kara recalled earning a chuckle from Lena as Cat glared at her.

"I was worried you weren't going to make it." Lena said to Kara. "I'd hate you to miss Supergirl again."

"Yeah, about that. I need to head downstairs and meet a source."

"But she'll be here any moment." Lena said.

"I know. But I'll be back and failing that I'll see her when she sees the children you brought over." Kara smiled.

"Who is this source? Someone interesting?" Cat asked.

"Are you allowed to ask that?" Kara questioned.

"Probably not. Who are they?" Cat pressed.

"I can't tell you." Kara said, partly as she didn't have one.

"Now I am really intrigued. If not the source, what's the story?"

"The story?"

"Yes the story. I mean that's why you meet sources. Unless this is a drug deal in which case the person in question would be your dealer not your source….unless I have fallen out of touch with street slang."

"They're a source." Kara said. "But it is, um, too, um, too early, yes too early to talk about the source or the story."

"Even to me?" Lena asked.

"Um well, it's bad luck to discuss a story before meeting the source." Kara said.

"I didn't know that. I really do have a lot to learn." Lena said. "But you will be back won't you. For once it would be nice to talk to both of you at once."

"I will do everything I can. I mean sure, but I may be in the background. I mean tonight is about Supergirl right? The rest of us, apart from the children, should be practically invisible, so that's what I'll be. Anyway I should go."

As Kara finished fumbling her way through an excuse and left Lena glanced at Cat and saw the final moments of an eye roll.

"You know?" Lena asked before commenting. "Of course you know. You're Cat Grant."

"Know what?" Cat asked.

"The thing that apparently neither of us are meant to know."

"Which is?" Cat asked.

"That we both owe Kara our lives."

"I guess there is no point denying it. We are both intelligent women. And we would need to be blind to miss it. But why doesn't Kara know you know?" Cat asked.

"It is kind of adorable watching her try to come up with excuses." Lena said. "And I know it sounds stupid as they are the same, but I find it so much easier talking to Kara rather than Supergirl. I worry if Kara knew I knew, our relationship would change and I don't want to risk that. What's your excuse?"

"Kara has gone out of her way to prove she is not Supergirl. It seems silly to make her think all that effort was for nothing."

"So it has nothing to do with you wanting to drop your knowledge at a time that suits you?" Lena asked.

"The infamous Luthor paranoia?" Cat asked.

"Maybe, but that wasn't a denial from you." Lena smiled.

"While I admit I am sure I will enjoy watching Kara squirm when I tell her I know, there is no ulterior motive."

"How many people do you think know?" Lena asked.

"As in officially or unofficially?" Cat asked.

"Either."

"No idea. Based on the inept lying I have come across I would assume Winn and James as well as her family." Cat explained before asking. "Do you want to flex your Luthor muscles?"

"I'm sorry?"

"We both know your family taught you how to play with your kill before the kill, I am suggesting putting those skills to a fun and non psychotic use." Cat explained. "Trust me it is therapeutic."

"I'm intrigued."

"Just follow my lead." Cat said.

"Ms Grant, Ms Luthor." Supergirl greeted formally as she landed on the balcony.

"Supergirl, how good of you to join us." Cat smiled. "You don't seem surprised to see me."

"Um," Supergirl hesitated for a moment before saying. "My friends keep me informed."

"With sources like that perhaps you should be the journalist, not Kara." Cat mused.

"Talking of Kara, I'll go and get her." Lena said.

"Kara?" Supergirl asked.

"Yes. She was so looking forward to seeing you." Lena smiled.

"Don't disturb her, I'm sure she is busy." Supergirl said.

"Nonsense, I mean she was really looking forward to seeing you. I'll be right back." Lena said walking out of the door.

"Actually, I have to go. There's a fire downtown." Supergirl said trying to come up with an excuse for leaving.

"You will be back won't you?" Cat asked.

"Yes, I'll be back. As soon as the fire is out." Supergirl said taking to the sky.

-00-

"Kara! There you are. I've been looking for." Lena greeted when she saw a flustered Kara in the corridor.

"You have? Is there a problem?" Kara asked.

"Of course not. Supergirl is in my office and I know how much you want to see her. Come on we can't keep her waiting."

"Right, yes, of course." Kara said following Lena back to her office.

"Where is she?" Lena asked sounding disappointed.

"There was a fire. She'll be back soon." Cat said.

"Excellent. I would have hated for you to miss her." Lena said to Kara.

"It would have been fine. I mean she must be really busy and have better things to do than talk to me."

"But you're her bff." Cat said.

"I am?" Kara asked sensing there was a trap somewhere.

"Well you must be. She gives you more interviews than she ever gave me. But I will concede when you write articles about her you have an uncanny ability to channel her. It almost feels like she wrote the article herself." Cat explained.

"And there was the time she rescued me because you asked." Lena added. "And as you said she is really busy. Too busy to respond to requests from just anyone."

"But we can ask her when she gets here." Cat said. "I mean she'll be back soon, she wouldn't want to disappoint all those sick children would she?"

"Absolutely not." Kara said. "But until she gets here I need to do a couple of um, um..."

"Interviews?" Lena suggested.

"Yes interviews." Kara said relieved to have an excuse.

"And who are you interviewing?" Cat asked.

"Um, the children." Kara said.

"All of them? That is impressive." Cat said dryly.

"No, not all. But a few."

"I know I am new to the media world, but you know what would be a perfect interview?" Lena asked. "A joint interview with one of the children and Supergirl."

"A...a...a joint interview?" Kara asked.

"A little sickly for my taste, but the public will lap it up." Cat agreed. "You are learning fast Lena."

"Thank you." Lena smiled.

"Don't let us keep you from the sick children." Cat said. "We'll bring Supergirl down when she arrives."

"Right." Kara said pulling her phone out as she left the office.

"Calling her shapeshifting Martian friend?" Lena guessed.

"That would be my guess."

"Which one will he come as?"

"I would guess Kara. She can't risk his wooden performance as Supergirl in front of so many people."

"Ms Grant, Ms Luthor." Supergirl said walking into the office.

"I take it all the fires have been put out?" Cat asked.

"Yes."

"And you managed to get rid of the smokey smell. I am impressed. How did you do it?"

"My Kryptonian genes." Supergirl said, trying to sound confident.

"The children will be pleased, especially those with asthma." Cat said.

"Shall we go?" Lena suggested. "There are so many children who want to meet you."

"Of course." Supergirl said, praying that J'onn had turned up.

As they entered the large conference room where the children were assembled Lena asked.

"I wonder what happened to Kara. She said she was coming down to interview children. I hope she is okay."

"I'm sure she is fine." Supergirl said.

"Once again you are so well informed." Cat said. "Don't let us keep you. Your audience awaits." She said waving to the excited children.

As Supergirl went off to see the children 'Kara' entered the room.

"Kara? There you are." Lena grinned.

"Lena, Ms Grant." 'Kara' said whilst standing to attention.

"Did you have a muffin accident?" Cat asked.

"Excuse me?" A confused 'Kara' questioned.

"Well you've changed clothes." Cat pointed out as 'Kara' stood stiffly.

"I thought these were more appropriate for children." 'Kara' said as J'onn silently cursed his error. "Anyway I should initiate the interview." 'Kara' said before walking towards Supergirl and the children.

As 'Kara' blundered her way through the interview Lena was sure she could see Supergirl wince before finally taking control of the interview. As Supergirl effectively asked and answered the questions 'Kara' stood rigidly.

Once the interview was done Lena approached Kara and asked.

"Are you feeling okay? You don't quite seem yourself."

"I am fine." 'Kara' said, still standing like she was part of a military parade.

"Are you sure? I know you've had a hard day."

"I'm fine." 'Kara' repeated before forcing a smile.

"That's good. I would hate to think this took it's toll on you. Once again you have come to my rescue." Lena smiled before hugging 'Kara'. As the hug took place even Cat had a hard time keeping a straight face as 'Kara' glared at Supergirl.

"You are welcome." 'Kara' said as she awkwardly patted Lena's back before pulling out of the hug. "But I have to go. Alex needs me."

"Of course." Lena smiled as 'Kara' marched away.

-00-

"That was …. fun. Cruel, but fun." Lena said when it was just her and Cat that remained.

"It was." Cat agreed. "I do miss tormenting her. But Lena, despite what we did tonight I am very attached to Kara. Don't hurt her."

"She is my best friend, my only friend. I have no intention of hurting her….but I may toy with her. I mean I am a Luthor."
