"Steve, hi." Kara said as she approached her apartment building the next day and saw him waiting by the entrance.

"Kara." He smiled.

"Everything okay? It sounds like you have been pretty busy recently."

"It's fine and thanks for looking after Martin. I didn't mean for him to impose."

"He hasn't." Kara said. "You want to come in?"

"Sure." He said following her inside. "Are you sure he hasn't been causing you problems?"

"He and Alex just do homework." Kara reminded him.

"That's true." He smiled.

As Steve and Kara walked into the apartment Chewie jumped off the couch and approached them. But on seeing Steve he started to bark and snarl.

"Chewie!" Kara chastised as she picked the dog up. "Easy, it's just Steve." She then looked at Steve and said. "Sorry, he has been a little jumpy since Alex."

"I get it." He said but Chewie kept snarling.

"Chewie!" Kara said louder looking at the dog. "That's enough." This time the command worked and Chewie quietened down.

"So I was thinking about restaurant we went to." Kara said.

"Which one?" He asked.

"The one we went to on our first date. The vegan one."

"What about it?" He asked not questioning any elements of Kara's statement.

"Sorry, I need to take this." Kara said looking at her phone, before moving to her bedroom where she changed into Supergirl before returning to the lounge, picking up Steve and flying him to the DEO.

"What's going on?" Vasquez asked entering the lab and seeing Steve tied to a gurney as a DEO doctor ran some scans.

"He's an imposter." Supergirl said.

"You sure?"

"Chewie is." Supergirl said before walking towards the imposter. "Where's Steve?"

"I'm right here." He said.

"No you're not." Supergirl said as another doctor entered the room.

"What are you doing?" Steve asked as the other doctor approached.

"Conforming you aren't Steve Keller." Vasquez said. "Then we can move on. Where's the real Dr Keller?"

"I am the real Steve Keller." The man said. "And I have not consented to giving you my DNA."

"That's not really an issue for us. If we think you are an alien we can pretty much do what we want." Vasquez said nodding to a couple of guards who held the man as the doctor swabbed his cheek.

"I'll run this." The doctor said leaving.

"Let's try this again. Who are you?" Vasquez asked. "And where is the real Dr Keller."

"I am Dr Keller."

"We don't have time for this." Supergirl said as Vasquez removed a cell phone from the man's jacket. She then tossed it to a guard and said. "Figure out where that cell has been."

"Yes ma'am." He said turning and leaving as Vasquez barked another order.

"And Spader, get J'onn down here."

"Yes ma'am." He said as he too left.

"You can't do this. I have rights." The man tied to the gurney protested.

"If you want any rights tell us where the real Dr Keller is." Vasquez said.

"I am Steve Keller. And I am about to become very rich for this breach of rights."

"See real Steve would never say that." Supergirl said.

"Yes he would because I have just said it." He countered as Vasquez looked at another DEO guard.

"Scott, confirm prisoner 6734 is still contained." She ordered.

"Yes ma'am he said leaving."

"Where is he?" Supergirl repeated, her anger obvious.

"Maybe you should check she is who she claims." The man said to Vasquez.

"Ma'am, there is an address he keeps visiting." Spader said entering the room again.

"Where?" Supergirl asked.

"254 Sycamore Ave in the East side." Spader said.

"On it." Supergirl said flying out of the cell.

"It could be a trap-" Vasquez called after her, only she was already gone.

-00-

As Supergirl reached the address she stopped in the air above the address. She then used her x-ray vision to look into the house.

"Vasquez, there are four people inside. Three have guns."

"We can have backup there in … seven min-"

"No need." Supergirl said flying through the house like a tornado, disarming and tying up the armed men before going into the cellar. Turning on a light she saw a familiar figure lying at the bottom of the stairs.

"Steve?" She called racing down to him. Moments later she scooped the unconscious man up and flew him to the DEO.

As she put him on a bed in the DEO infirmary doctors started to secure him to the gurney.

"What are you doing?" Supergirl asked.

"He could be an imposter." Vasquez said approaching her. "Why don't you bring in the ones who did this while we test him?"

"I thought you had sent a team to clean up?" Supergirl asked.

"We did, but you can bring the guards here quicker. The sooner we speak to them, the sooner we'll have answers." Vasquez said.

"Okay." Supergirl said disappearing in blur and returning in similar fashion with the prisoners.

"Let's move them into interrogation." Vasquez said ushering Supergirl out of the infirmary as the doctors ran the tests on Steve.

As Supergirl put each prisoner in a separate cell Spader approached Vasquez.

"What have you got?" Vasquez asked.

"The first Dr Keller was a fake." He started.

"Told you." Supergirl said.

"He is not prisoner 6734, but other than that we don't know who he is. The other Dr Keller, has been confirmed as Dr Keller."

"I'll go see him." Supergirl said.

"Wait." Vasquez said.

"What?" Supergirl asked.

"You might want to change." Vasquez said. "Seeing Supergirl at his bedside might freak him out."

"Right." Supergirl said leaving.

"Kara?" Steve asked waking up and seeing her sit nearby.

"Hey, how are you feeling?" Kara asked moving closer to the infirmary bed.

"Okay I guess." He said sounding confused. "Where am I?"

"The DEO." Kara explained.

"How?"

"Supergirl found you." Vasquez said approaching him.

"Didn't even know if anyone was looking for me." He mused.

"Can you tell us what happened?" Vasquez asked.

"Um, I was running through the park, like normal and I think something hit my head. I must have had a really bad concussion as after I woke up I kept seeing me." He said before saying. "You aren't looking at me like I'm crazy."

"You're not." Kara said. "Some one assumed your identity."

"Why? And how long?" He asked before seeing the wall clock. "Is that date right?"

"Um yes?" Vasquez said looking.

"Four days? I've been gone four days. Oh my god. Martin?" Steve said sitting up straighter, wincing as he did so.

"He's okay." Kara said. "He'll be here soon."

"What did the other me do?" Steve asked.

"We're not sure. But we'll figure it out." Vasquez said. "But to do that I need to ask you some more questions."

"Anything."

"What do you mean you kept seeing you?" Vasquez asked.

"Right. I was kind of out it. But I remember waking and seeing me lean down over me touching my face."

"Maybe that is how he can copy someone?" Vasquez said to Supergirl. She then looked back to Steve and said. "Do you know how often he did that, was it once a day or every morning?"

"It was different times." Steve said. "Maybe. Or maybe not. But I remember the lighting was different. And one time he bought me food. Where is he?"

"Here, in containment. Supergirl captured him." Vasquez said. "Did the other you ask you anything or talk to you?"

"No. Not a word." Steve said. "I'm sorry, I'm not being much help."

"You're doing fine." Kara smiled.

"If you'll excuse me I need to go. I'll see you later." Vasquez said leaving.

"You sure you are okay?" Kara asked.

"I think so, but Martin -"

"He's okay. And he can stay with us until you get out." Kara said.

"Thank you."

"Don't thank me. I should be apologising." Kara said.

"Why?"

"This is probably my fault. You were probably targeted because of me. People close to me always get hurt. You should keep your distance."

"You're worth the danger." Steve smiled. "You're my only babysitter. Or at least the only one Martin likes."

"I think Martin would object to having a baby sitter." Kara pointed out. "And I was being serious."

"Nearly three years ago I was the on call surgeon in the ER." Steve started somewhat randomly, making Kara wonder if he had concussion. "A guy came in looking for a hit. I refused. An hour later he attacked a nurse in order to get access to the drugs. She got hurt because of me. I know I chose the right thing, but it still hurt. That said, she didn't blame me. At the time she told me the only reason she would have been mad at me was if I did the wrong thing. But as long as I kept making the right choice she wouldn't be angry." He said. "Now I have no idea what is going on right now. But I know you and you are a good person with a strong moral compass and if that was the cause I'm okay, because after everything you have done for me, what's a little kidnap?"

"You are one strange man." Kara commented.

"So I have been told. But in this case it could be the drugs they have pumped me with." He smiled as an Agent walked in.

"Ma'am. They're here."

"I'll be right back." She said to Steve before leaving.

"Hi." Kara said when the teenage Alex and Martin approach her. Seeing Diz in the background she signalled to him to wait. Nodding, he went into one of the meeting rooms.

"What's going on?" Her daughter asked.

"Come in here and take a seat." Kara said. When the two teens had followed her instructions she went on. "There is no easy way to say this." Kara said looking at Martin. "But I met up with Steve today and he wasn't acting normal. I found out who I was talking to wasn't Steve. It was a body double." She explained before looking at her daughter and adding. "Like what happened to your aunt." She then looked back at Martin. "The good news is we found Steve, the real one, and he is okay. But he will need to stay here for the next day or so. So you are going to be staying with us." She said looking at Martin.

"How long was has it been the fake Steve?" Martin asked.

"We think four days."

"Good." Martin said.

"Good?" Kara asked confused.

"It means everything he said wasn't him saying it."

"You want to talk about what happened?" Kara asked.

"No. Can I see him?"

"Sure." She said standing. She then looked at her daughter and said. "I'll be right back." She then led Martin towards the infirmary. As they walked she asked. "You sure you are okay and the other Steve didn't hurt you?"

"I'm fine." He said. "But is Steve really okay?"

"He will be." Kara smiled as they walked into the infirmary.

"Steve." Martin said rushing over to the bed and hugging his uncle.

"You okay?" Steve asked.

"I'm fine."

"Did the other me do anything to you?" He asked.

"I'm fine." Martin said.

-00-

"Are you okay?" The teenage Alex asked her mom when Kara reentered the small room.

"Why wouldn't I be?"

"You said Steve was acting strangely."

"It wasn't anything major. And it was Chewie that proved it." Kara said. "Do you know what happened between the fake Steve and Martin?"

"He told Martin he was unwanted and it was time he stopped being such a burden. Then he just cut himself off."

"That's why Martin has been over every night this week?" Kara guessed.

"Yeah. He didn't want to see Steve."

"Why didn't you say anything?"

"I just thought they had a fight and Martin was cooling off. I'm sorry."

"Right now that doesn't matter. What matters is Martin. You know more than most what he is going through. He's going to need a friend." Kara pointed out. "You okay if he stays with us?"

"Why wouldn't I be?"

"I know you are still struggling with your powers at night. He could stay with MJ."

"It's only for a day or so plus I can wear the inhibitors." The teen said.

"Okay. Stay here, I'll be back in a minute." Kara said leaving her daughter alone and walking towards the third teen.

"Hi Diz. Thanks for that. I didn't want someone he didn't know picking him up."

"No worries."

"I didn't want to interrupt your evening." Kara apologised.

"Not like I had plans anyway." Diz shrugged.

"In which case can you give us a ride home?"

"Sure."

"You are welcome to stay for dinner."

"Won't that be weird?"

"From what Kara said it was a mutual decision and you are definitely not the bad guy."

"Does her mom see it like that?"

"Alex is still stuck in bed. You won't see her. Besides I'm sure MJ would like to see you."

"You sure?" Diz asked.

"Of course." Kara smiled. "Besides Martin and MJ might want some more male company."

-00-

"About time you got back." Alex said when her sister entered her bedroom.

"Hello to you too." Kara replied.

"What the hell is happening? Steve was really taken over? Why and when? And how did fake me escape the DEO?"

"They didn't. He or she is not who took your identity."

"There are two of them?"

"Seem to be." Kara said. "Right now we have far more questions than answers."

"Well what happened?"

"Steve came by and Chewie got very agitated. Then I asked him about the vegan restaurant we went to on our first date."

"And he didn't know that you had hadn't dated and you wouldn't do vegan?" Alex guessed.

"No. So I flew him in."

"How's Steve?"

"Shaken, but okay. I said Martin would stay with me until he was released."

"Is Alex okay with that? I mean he can stay here if she's worried about nightmares."

"She said she was fine with it." Kara said. "Besides he stayed over last night, probably to avoid fake Steve."

"How is Martin?"

"Relieved that it hasn't been Steve for the last 4 days."

"Why? What happened?"

"Fake Steve told him he was unwanted and a burden."

"Poor kid." Alex said as she heard a familiar voice from downstairs.

"Is that Diz?" Alex asked confused.

"Yes, I had him pick up Marin and Alex. And then I invited him to dinner."

"Isn't that a little weird?"

"That's what he said. But I told him we didn't think he was the bad guy. I also promised that you were bedridden and he would be safe. Besides, maybe he can talk to MJ?"

"MJ would need to be here for that." Alex pointed out.

"And he's not?"

"No. Out with Jess. Again. At least according to the message he sent me." Alex said sounding frustrated.

"At least he is over his guilt." Kara pointed out.

"And back too far the other way." Alex said frowning.

"Want me to talk to him? Or extract him and bring him back here?"

"No. I'll catch him when he gets back."

"Okay. Well can I get you anything?"

"Not at the moment."

"Okay, well I'll bring you up some food in a bit." Kara said. "Oh, you are about to be sent some photos, can you look at them?"

"Sure, what are they of?"

"The guys holding Steve."
