"So what do we have?" Supergirl asked.

"A shape shifter. Not from Fort Rozz." Hank explained.

"Good, bad or unknown?" Suerpgirl asked.

"Unknown. He has been using his ability to undertake petty crimes, so although he seems off world domination, he is risking exposure." Hank said.

"So bring him in here?" Supergirl asked.

"Not so fast. We still don't know if he has other abilities. We don't even know what race he is."

"But he is somewhere isolated now?"

"He is."

"So I'll go in and talk to him. He is unlikely to be able to hurt me."

"That is a big assumption." Alex said, the disapproval in her voice obvious.

"If we wait and he moves somewhere populated it is a bigger risk." Supergirl pointed out.

"I wasn't suggesting we waited, I was suggesting we did this as a team, so you have the backup you need." Hank said.

"Sir, he's moving." One of the analysts said. "He is heading to his truck."

"I can be there before he turns the engine on." Supergirl said.

"Go." Hank said. "Everyone else let's move." As he fell into step along side Alex he commented. "We need a no sugar rule before lunch for her. She is far too hyperactive this morning."

"What do you want?" The man asked as Supergirl landed in front of him, cutting him off from his truck.

"To talk."

"About?"

"Where you're from, what your plans are." Supergirl listed as the man nervously looked around. "I would like you to come with me."

"I'd rather not."

"Please come with me."

"I don't mean any trouble. Please let me go." The alien asked.

"I can't do that. Not yet. Just come with me and no one will get hurt."

"No please, I don't want to be locked up. I don't cope well in confined spaces." The alien said backing away.

"We just want to talk with you." Supergirl said stepping closer.

"No, I can't go. Please step back I'm getting nervous." The alien said.

"You have nothing to be nervous about."

"Please, you don't understand."

"Understand what?"

"Since coming to this planet I lose control when I get nervous. I can't help it. Please I don't want to hurt you."

"You won't." Supergirl assured him.

"Stand back, please. I'm losing control." He said as his skin started rippling. "It's starting. Go." He pleaded as Supergirl heard Alex say.

"Get out of there, now."

"I don't want to hurt you. You don't have to be scared." Supergirl said to the alien.

"It's too late. Go." He begged seconds before large needles shot out from him. Supergirl instinctively turned a shielded her herself with her cape. However even with the cape covering most of her, parts of her left arm were still exposed and to her distress one of the needles penetrated it. The unexpected pain caused her to release the cape with her left hand, exposing more of her to the second wave of needles which stabbed into her. As she collapsed in a heap she was vaguely aware of movement but the pain caused her to black out.

When she finally woke up she saw Alex's worried eyes looking at her.

"Easy." Alex warned.

"What happened?" She asked instinctively looking at her now needle free arm.

"Apparently you aren't immune from his needles. I've taken them out and they don't seem to have caused any damage."

"Thank you."

"Kara-" Alex started only for Hank to interrupt.

"You're awake, good. Any permanent damage?"

"Doesn't seem to be." Supergirl smiled before asking. "How is he?"

"Scared and confused."

"You are going to help him right? He didn't mean to do it."

"I am. But I can't release him until he has proven he is not a danger. Based on today's performance there is a long way to go."

"Can I see him?"

"Sure, just try not to give him another panic attack this time." Hank replied leading Supergirl from the room, leaving Alex shaking her head as her frustrations at Kara's actions built.

-00-

"Please I don't want to hurt anyone. I just got nervous." The alien said as he saw the outer doors open. On seeing Supergirl he exclaimed. "You're alive. I'm sorry I didn't mean to hurt you."

"I know." Supergirl smiled warmly.

"I didn't mean any harm. I am not bad." The alien repeated.

"And that is why I am offering you a chance at freedom." Hank said. "I can not release you while you have no control. But I am willing to have my team help you gain control." Hank smiled. "You have a name?"

"None that a human tongue can speak."

"How about Peter then?" Kara suggested.

"I like that. Thank you."

"Now that is decided get some rest. Your training starts tomorrow." Hank said leading Supergirl out of the cell. When in the corridor he asked.

"Why Peter?"

"Hunger Games marathon last night, I guess the name was in my head."

"Hunger what?" Hank asked confused.

"You really need to leave this place more often." Supergirl laughed. "Anyway I'm going to say goodbye to Alex then I'll head back to work."

"When you see her, go easy on her. She thought you had died earlier. It had her rattled." Hank said.

-00-

"That was a pretty intense morning." Supergirl commented when she ran into Alex in a DEO corridor.

"Pretty intense? You nearly got yourself killed, again, all because you didn't listen." Alex said struggling to remain calm.

"We got him." Supergirl shrugged not wanting to admit to Alex how worried she had been when the needles had hit her.

"That is not the point." Alex said shaking her head. "Come with me." She instructed before dragging Supergirl into the training room.

"You want to practice? Now? I have to get to work."

"No I don't want to practice." Alex snapped.

"Then why are we here?"

"Courtesy."

"What?" Supergirl asked perplexed.

"If you weren't my sister I am not sure I would have waited this long and I would probably do it out there, but you are, so we are doing it in here."

"Doing what? Are you feeling okay? You are acting really weird."

"Of course I am not okay. You nearly died." Alex shouted. "You have to stop being so reckless. He didn't even want to hurt you and nearly killed you. How can you possibly think you can face the prisoners of Fort Rozz and survive? You only beat Astra because she wanted to be captured and even then she could have killed you multiple times. Your carelessness got Hank captured by Non. And today? What if there had been people around? Not only would you have nearly died, all those people would have died.

"This isn't a game. And just because you have powers doesn't mean you are invulnerable and it definitely doesn't mean the rest of us are. When you lost your powers I was actually glad, because I thought you might learn something from it. You might learn how fragile life is and you would use that knowledge to become better, stronger, more careful. But no you just forgot the experience. Sometimes I wonder of you brain is as impervious as your skin."

"You done?" Supergirl asked, the sorrow and pain evident in both her voice and eyes.

"Yes." Alex said waiting for her sister to argue or defend herself. When Kara just turned and walked away she realised she had overstepped and called. "Kara, wait." But it was too late, her sister was gone.

-00-

Alex felt bad. It wasn't often that she and Kara really fought, but today had definitely been one of those days. She had been so scared when she had seen Kara lying unmoving on the ground. For a moment she thought she was dead and her world had stopped. As soon as she was sure Kara would be okay and the relief passed she had felt the anger rise. She had felt herself loosing control and had been surprised she lasted so long before ranting at her sister. But when she had finally lost her temper even she was surprised at the ferocity of the attack. During the shouting she had felt like she was kicking a puppy, but she had kept going, desperate for Kara to understand how dangerous life was. She would do anything to protect Kara even screaming at her if it meant not losing her to stupidity.

Even as she was shouting at her it had been obvious Kara hadn't appreciated the shouting or the reasons behind it. Even Hank suggested she had been too hard on Kara. So Alex shouldn't have been surprised when Kara silently flew off but since then Alex had been feeling guilty and worried, especially as Kara was not answering any of her calls. But it was Friday and that normally meant TV and pizza night so she had turned up to Kara's empty apartment and hoped her sister did the same.

When someone knocked on the door she was growing worried about where Kara was and was distracted enough not to notice it was a new pizza guy. As she reached for the box she was distracted enough to almost not notice the taser he was holding.

Immediately alert she knocked the taser from him, but in doing so left enough room for him to kick her in the knee sending her back into the apartment. Hitting the ground hard she tried to shake off the effects and get to her feet, only her opponent was once again on her and hit her before she was standing. Lying on the floor seeing him about to kick her she managed to block his foot with enough force that he fell back into the table sending chairs flying.

Taking the opportunity she got to her feet, only to have her kicked knee give out and fall back to the ground. Muttering she dragged herself across the floor towards the kitchen and the supply of knives.

She was just reaching up to a draw when she felt a hand on her head moments before her head was violently smacked into the side and her world went black.

-00-

When Kara flew into her apartment she wasn't sure if Alex would be there or if she wanted Alex to be there. She knew she had been in the wrong, but being told she was stupid didn't help achieve anything. Upset she had gone to work sorted out a months worth of filing then soared over the city indulging in one of her clear her head flights for longer than she should and by the time she arrived home, hours after she should have done, she was exhausted. Flying into her lit apartment she guessed Alex was there, however, she didn't immediately see her. When she called out and got no reply she moved into the middle of her apartment and was immediately concerned by the carnage that she saw, with furniture toppled and what looked like blood.

She immediately tried ringing Alex and was dismayed when she heard a phone ring from near her TV. Moving over to it she picked it up and confirmed it was Alex's. Trying to suppress her panic she dialled Henshaw and then waited for the DEO agent to arrive.

-00-

"This is my fault." Supergirl said pacing through her apartment. "If had been home when I was meant to this wouldn't have happened."

"Or you would both have been taken." Henshaw suggested. "Blaming yourself won't help find her." He added as another Agent approached and handed Henshaw a tablet. The senior agent then looked at Kara and said. "It is definitely Alex's blood."

"I'll search for her." Kara said flying off as Hank ordered every asset to join in the search.

-00-

Alex woke up in a cold dark room trying to remember why her head hurt so much. She remembered her fight with Kara and waiting in Kara's apartment, then she remembered the pizza guy and the ensuing fight, which she assumed she lost. Carefully she sat up and tried to figure out an escape. Her hands were bound, but her legs weren't giving her a glimmer of hope that she could fight her way out.

Standing she gingerly moved round the room unable to put much weight on her knee. As she moved round the room she looked for something sharp to cut her free or a suitable weapon. Finding none she went to the door and listened for signs of life outside. Just when she thought she was completely alone she heard footsteps approaching. Backing away from the door she looked for a good place to launch an ambush. Once content she had found one she crouched slightly and waited.

As soon as the door opened and she saw a figure enter she launched herself at him taking him down with some well aimed kicks. She then seized her opportunity and headed for the open door. Unfortunately she was not expecting the two men who stood outside the door who roughly grabbed her and shoved her down to the ground. When they were happy she was subdued they each grabbed an arm.

As they dragged her down the corridor she looked out for any clues to where they were. But all she saw were walls and fluorescent lights. Finally she was dragged into another room and deposited on the floor.

With Alex on the ground four men stood over her, all carrying baseball bats.

"Afraid of a fair fight?" Alex asked with more confidence than she felt.

"It is not a fight that we want." One of the men said.

"What do you want?" Alex asked.

"Information." The man replied. "You will tell us everything you know about Suoergirl."

"Go to hell." Alex spat out.

"The only one who will be experiencing hell is you." He said kicking her in the gut. "So will you tell us?"

"I will never tell you anything." Alex said.

"Well that will make today a lot more enjoyable for us." The man replied before he gave a signal to the others who all started unleashing blows on the captured agent.
