"Being a reporter is not permission to be late." Cat chastised as Kara rushed into Lena's office.
"Sorry Ms Grant I got stuck in traffic...wait Ms Grant? What are you doing here?"
"Do I need you permission?" Cat asked.
"No umm, I meant I was um-"
"Words Kara, use them." Cat said.
"I thought you were in D.C." Kara finally said.
"And I thought you were an up and coming reporter. But seeing you aren't even aware that the President is visiting here it turns out we were both wrong."
"The President?" Kara asked looking round the room.
"I didn't mean now or here. She's coming tomorrow to National City." Cat said. "What on Earth do you do all day to not know this?"
"I um -"
"Words would be a start." Cat said shaking her head. "Seeing your association to me I don't want you to embarrass yourself and therefore me tomorrow at the press conference."
"What press conference?" Kara asked.
"Have you suffered some type of traumatic head injury?" Cat asked.
"No?" Kara replied.
"Was that a question or a denial?"
"A denial?"
"You don't sound sure." Cat said before turning to Lena who was silently watching the exchange. "Are you sure you want to risk using her tomorrow?"
"Using me? To do what?" Kara asked.
"Don't worry." Lena said. "It's just a simple demonstration."
"Demonstration of what?"
"My new species detector. It is like my alien detector only it actually gives species and traits. Including human so it isn't discriminatory. The President will announce buying several units for the White House and Cat thought a live demonstration would be a good idea. So I suggested you and Supergirl."
"Supergirl?" Kara asked.
"Yes. Supergirl. She will use it first to demonstrate as an alien and then you as a human."
"Supergirl has agreed?" Kara asked.
"Yes."
"She has?" Kara asked completely confused.
"I own Supergirl." Cat shrugged.
"But she is pretty busy...I mean what if there is an attack?" Kara asked.
"Then she swoops in the hero." Cat said.
-00-
"You okay?" Alex asked noticing how stressed Kara was looking.
"No."
"What's wrong?"
"Cat's back."
"For good?"
"No. Just for a press conference tomorrow."
"What's the issue?"
"Firstly it gave me major flashbacks to my first week working for her. Secondly she wants me to participate in the press conference."
"You?"
"Yes. And by me I mean both of the mes."
"That could be good. J'onn can pretend to be Supergirl while you be you. Having you both on live TV at the same time will help your cover."
"That's clever...but only solves half the problem."
"What's the other problem?"
"Lena's new species identification gadget is what is being launched at the press conference. If J'onn is me he'll still show as Martian and when I'm me I'll show as Kryptonian."
"Call in sick."
"To Ms Grant?"
"You don't work for her any more." Alex reminded her.
"So? You can never escape her power." Kara pointed out before exclaiming. "Oh, I have it."
"What?"
"I'll get the President to use it."
"That will show she's an alien." Alex said.
"Precisely. No one will believe that so the demo will be called off."
"Or people will believe it and it will destabilise the country." Alex said. "Turn up as Supergirl and call in sick as Kara."
"Ma'am, an alarm has been activated at L-Corp." Vasquez called to them.
"On it." Supergirl said flying off.
-00-
"Ms Luthor? Is everything okay?" Supergirl asked flying through her window.
"My fault, I needed to speak to you and seeing you haven't given me your phone number, despite all we have been through, I had to trigger an alarm." Cat said.
"What do you want?" Supergirl asked folding her arms across her chest.
"Please, no more games. I know you know why I summoned you."
"I-"
"Don't deny it. After all you are not surprised to see me, which means someone told you I was here and therefore why I was here." Cat said.
"I..." Supergirl started only to trail off confused.
"I thought it was prudent to have a run through tonight." Lena explained.
"Tonight?" Supergirl asked.
"Yes. Just as soon as Kara gets here." Lena said enthusiastically.
"Kara?"
"Someone you are clearly spending too much time with as your ability to use the English language is as bad as hers." Cat said.
"I need to go. There's a bank robbery." Supergirl said leaving.
-00-
"Help!" Supergirl said landing in front of Alex and J'onn. "They are doing a test run tonight."
"You're Supergirl. Tell Ms Grant you are not at her beck and call." J'onn said.
"Great plan. I tell you what, I'll be Kara and you be Supergirl and I'll watch as you tell her." Kara said.
"Fine, we won't do that." J'onn said.
"This is bad." Kara said gripping the back of a chair and accidentally crushing it. "That's it." Kara said before looking at J'onn. "I need you to be me. Kara me. And go to L-Corp. Now." Before J'onn could answer she had flown out of the DEO.
"When did I become your sister's body double?" J'onn asked.
"Well you do like the skirt." Alex pointed out.
-00-
"All arrested?" Cat asked when Supergirl returned.
"Arrested?"
"The bank robbers." Cat clarified.
"Yes."
"Really there was nothing on the news." Cat pointed out.
"By yes I meant..."
"No?" Lena suggested.
"Yes. They were arrested as in their progress was arrested, it came to a halt." Supergirl explained.
"I don't need an English lesson." Cat pointed out.
"The robbery was arrested by an alarm. They were gone by the time I got there." Supergirl said as the office door opened and Kara walked in.
"Ms Grant. Ms Lu- I mean, Lena." Kara greeted.
"You are helping with a demonstration, not attending boot camp. You are allowed to slouch." Cat pointed out when she saw Kara stand rigidly in the corner.
"Can we get this over with?" Supergirl asked.
"Of course." Lena said. "Just put your finger on here." Lena said holding out a box. In response Supergirl pressed her finger down hard enough to crush the device.
"I'm sorry. I don't know my own strength sometimes." Supergirl said.
"Not to worry, I have plenty more." Lena said. "I'll go get some spares."
"How many spares?" Kara asked.
"A whole warehouse." Lena smiled. "Although in this case a whole desk full." She said pulling one out of her top drawer.
"Shall we?" She said holding it up to Supergirl to gently touched the device.
"Look at that you are a Kryptonian." Cat said.
"You hear that?" Supergirl said before flying out of the window.
"Where are you going?" Cat asked Kara noticing she was leaving.
"There could be a story." Kara said disappearing in a hurry.
"When are you going to tell her the visit has been cancelled?" Lena asked Cat.
"Another hour? I'm curious what flimsy excuse she'll use next."
-00-
"I'm sorry did our professionalism interrupt your date?" Cat asked when Kara entered the office an hour later, shortly followed by Supergirl.
"It's busy out there." Supergirl replied.
"Quite. Well now everyone is here, perhaps we can finish the rehearsal. Kara, put your hand on the device." Cat instructed.
"You know what would make a great picture?" Kara asked. "The President using the device"
"You want me to use the President as a Beta tester?" Lena asked.
"I don't think that is a good idea." Supergirl said in a disparaging tone.
"The Secret Service were hesitant enough of me being in the same room as the President. Testing the device on her might give them heart failure." Lena pointed out.
"That is a good point." Supergirl said. "I need to go, there is an emergency down town." She said jumping from the window.
A moment later J'onn entered the office in a suit.
"Ms Luthor, I am Agent Henshaw. I believe you are supporting a press conference with the President tomorrow?"
"I am."
"And you are planning a demonstration?"
"I am."
"I need to take the device for testing. It will be waiting for you at the press conference."
"That's clever." Kara commented a little too loudly.
"What is clever?" Cat asked.
"Ensuring nothing is tampered with before the press conference." Kara said. "Keeping the President safe."
"You are praising Mulder for doing his job." Cat pointed out.
"And I thank him for his service." Kara said awkwardly as J'onn picked up the device and left the office.
"Ms Danvers you need to accompany me for vetting." J'onn said leading her out of the office.
"Once again that was a fun evening." Lena said. "I never thought I'd enjoy your visits."
"It's a new world." Cat commented. "Try not to break her before my next visit."
