Do not own CW characters.

A/N Okay no kidding this time. This story is going to be short, no more than four or five chapters. Think of it like an episode. Just to get some things clear this story is in no way a pairing of anything or anyone. Just something to help me decompress from finishing Call me Kara. Its supposed to be funny. At least its funny to me and gives me something to do during the hiatus. I was annoyed that National City was not involved in the crossover so here is my take on it. This is a LOT, Arrow, Supergirl crossover in that it will involve all major characters from Supergirl, Oliver Queen, Sara Lance and Mick Rory (Kara never did call him) Enjoy and take it for what its worth. I plan to start a new SG story soon but this is me decompressing before I get involved in another long story. There will be hints of Supercorp that Sara can't help but point out to an oblivious Kara.

Chapter 1

Kara Danvers had enough. The day had been long, listening to her boss once again tell her what a horrible writer she was, reminding her that the only source she had cultivated was a colorful, skirted superhero who wouldn't actually come forward on the record and she couldn't get the simplest assignments done. Kara pointing out that she was close with Lena Luthor had also not won her any points.

"Yeah, she came to Catco to invite you to a party, right? I saw the two of you. Judging by the look she was giving you, I would imagine she wants to give you a lot of information. Unfortunately it's not the kind we print here so get on the streets and bring me something that doesn't belong in a skin magazine."

Kara was not sure what Snapper meant to infer by that and when she had asked her sister, Alex looked away and was strangely silent on the issue. Deciding she had enough for the day the heroine returned to her apartment for a long shower and pigging out in front of the television. Things had been quiet since Lillian Luthor had been taken into custody and though the Henshaw Cyborg was out doing who knows what, she needed this time to herself, especially after the who alien invasion thing. Kara had a lot on her mind, mostly Alex and this Maggie, who while it may have been inadvertent, hurt her sister but then decided she wanted her, Eliza's assertions that Mon El "liked" her, the kiss the two shared that he claims not to remember, this Guardian running around the city, while helping, could also get himself killed and keying down from the recent events on what Barry likes to call Earth 1. Where did he get off saying she was Earth 38? She had half a mind to use her gadget to call Cisco and Barry and have an in-depth discussion on the unfairness of the two being able to number Earths.

At some point during commercial breaks, Kara had drifted off, her mind dreaming of seagulls, beaches, and crullers, also known as her happy place.

Her super hearing woke her up. Normally, Kara was a fairly heavy sleeper, having learned to tune out most sounds unconsciously years ago. But this was different, this was someone calling her name. A voice she recognized being in pain, a hiss almost, and strangely enough it was coming from outside her window.

"Kara!"

Kara jumped up, considered changing from her extremely comfortable pajamas into her Supergirl costume but doubted anyone wanting to harm her would take the time to call out to her first.

She walked carefully towards the window, using her X ray vision to check the surrounding brick and was shocked to see a hooded figure hanging onto the side of the wall. Though dark and unable to make out the face, she knew of only one person that could scale a building this high and also wore a hood.

Lifting up the window she looked to the right side and sure enough, there he was, holding onto a brick ledge with one hand, both feet planted on the wall and a bow in the other hand.

"Oliver?"

"Yeah, think you could give me a hand?"

"Why are you out there? Why are you here?"

"All very good questions I would be glad to answer if you would give me a hand inside!"

"Why didn't you just come in through the front of the building?"

"Dressed like this? Would you please, pretty please help me inside?!"

Kara reached for him, and Oliver pushed off with a grunt, swinging into her grip. She noted for the first time his bow had a cable attached to it, leading to the roof.

Pulling him in with no problem, she moved quickly to turn on the lights and saw Barry's mentor who had shot him. A good guy, even if he did need to loosen up a bit. Checking him over, she stopped short at his right thigh.

"You're bleeding!"

"I don't need you to tell me that, Kara." Queen told her, biting sarcasm evident. He limped over to her couch.

"Wait!" Kara moved quickly and was back with several old towels that she laid across her favorite piece of furniture. Oliver looked at her questioningly and she shrugged her shoulders. "I wasn't sure if you were bleeding anywhere else. I don't want blood on my couch. It's my favorite piece of furniture." she explained. Oliver threw his hood back but managed not to roll his eyes.

"What happened to your leg?"

"A knife happened. Can you control how hot that heat vision of yours is?"

"Yeah…why? Do I even want to know?"

"It won't stop bleeding. Mick pulled the damn knife out before I could package it and even though it's my quardricep it won't stop bleeding. I need you to cauterize it." the Arrow explained.

"You want me… to burn… your leg… to stop the bleeding?"

"Unless you have something better to do at midnight? No one is here, right? I guess not judging by those pajamas."

"Excuse me? What is that supposed to mean?"

"Nothing. I'm going to rip the pant leg just a bit and you can burn it."

"Its going to hurt. Why don't we go to the hospital? Stitches! Most people use stitches! Yes, we can go to the hospital, I'll fly you there…"

"Look at me! Do I look dressed to go into an ER? Besides the National City Police may be looking for me. I can do my own stitches if you have surgical thread?"

"Yeah, because indestructible aliens keep surgical thread in our apartments in the event bleeding vigilantes from other universes come crawling through the seventh story window at midnight!"

"Then cauterize it! I've been burnt before, its no big deal!"

Kara had enough of his attitude. "Have you ever considered being a bit nicer to me? Why can't you be like Barry?"

"Felicity asks me the same thing all the time." Oliver admitted, trying to use a towel to keep pressure on the wound. "I am nice to you. We had the group hug and everything. I apologized for treating you rudely when we first met."

"Yeah, fine, then a week later you show up wanting me to cauterize your wound while making a joke about me being single because of my pajamas!"

"I wasn't making a joke. It was just an observation. I will be glad to answer all of your questions, if you could just please stop the bleeding." Oliver patiently offered.

Kara ripped his leather pant leg over the wound and unleashed her heat vision, a bit hotter than she probably had to. To his credit, he tensed and hissed but did not scream. Sadly, she guessed he wasn't lying. This wasn't the first time he had been burned. She eased up on the heat, and blew a bit of freeze breath for relief. She wasn't a sadist.

Oliver leaned back on couch and let out a couple deep breaths. "Thank you. You have any burn ointment or an antibiotic for the wound? I would rather it not be infected until I have finished what we came here to do."

"Yeah, I have some burn ointment. Alex burns herself a lot trying to use my stove. I don't know why, she can't cook, not that I'm a great cook either. Are you hungry? I don't really have anything, I do have some leftover pot stickers and …why are the police after you? And did you say Mick? The guy who burned his family and then wanted me to call him? That Mick? Isn't he supposed to be traveling through time or something, safely in another universe?"

"Ointment?"

"Oh right." Kara moved off quickly, back with the burn ointment and handed it to him. "You do it. I'm not good with treating injuries surrounded by blood. I can check you over for any other wounds with my vision as soon as you tell me what is going on, why the police want you, why you are even here and most importantly why you brought the lunatic who was flirting with me? This is my Earth and if he calls me skirt here I am tossing him a long ways."

Oliver rubbed the oil in and sat back. He slipped his quiver off and dropped the bow. Kara noticed the quiver was missing quite a few arrows. Pulling his mask off, he looked at the most powerful woman in the universe wearing a faded blue t shirt that had seen better days and pajama pants that had what he thought were the main characters from Lady and the Tramp. Kara noticed him looking.

"One word about my clothes and you can go back out the way you came." she warned.

"Didn't even cross my mind. Sara and the rest of them came back to Star City after the Dominators were gone. Apparently some woman named Shiva was there to conduct an arms deal. The weapon was a nuclear warhead. She leads a terrorist organization called the Brotherhood of the Fist…"

"Cool name." Kara admitted.

"This brotherhood is collecting an arsenal of weapons, hoping to one day take over China by coupe and take control of its nuclear arsenal and military. Somehow she was able to do this by acquiring weapons the likes of which had never been seen. Sara believed she was given these weapons from the future by a time pirate with the express purpose of helping her achieve her goal. She came back with her team and we were able to stop the sell but her and her team escaped."

"Good job." Kara mumbled, then stopped at the look from Oliver. "No seriously, good job stopping the sell. Go team." The Arrow ignored her criticism and carried on.

"We tracked her down to Central City, where she attempted to break into S.T.A.R. Apparently Barry and his team are off running different dimensions, hopefully not screwing up any more timelines and dealing with some threat called Savitar. Don't ask, I don't know, and unless he asks for my help, I don't want to know. Anyway, only that useless new Wells was there and though she wasn't able to find any weapons she did find one of Cisco's toys, a back up to your inter dimensional key, if one of us needed to get to you and Cisco and Barry weren't around. Of course the idiot left it on his desk and when we cornered them, she used it. Her and her seven friends jumped into the breach and Sara, Mick and I were able to jump in after her before the breach closed."

"Okay, I'll use mine to send you three back and can take care of the nina lady and her posse. No problem. Where are Sara and …him? We can do this now."

"No we can't. We have to track her down and bring her back. She has a lot of connections, a lot of stockpiles and a link to this time pirate. If we can identify him, Sara and her crew can stop this whole thing. When we arrived here she was waiting for us and a fight broke out. We were able to hold our own but the police arrived. She took the opportunity to stab my leg and we all had to go in different directions before we got arrested. Sara found your address in a phone book and I agreed to come here while she and Mick continued the search. They will be here in the morning if they can't find any sign of them. We may need you to sweep the city and see what you can find."

"No problem. I'll wrap them up and bring them to wherever and you guys can take her back to your universe. Believe me I have enough of my own problems walking around here. The head of this Alien hating group who has had my adopted father kidnapped for over a decade just got arrested but there is this Cyborg that hates me and wants me dead. Plus I have this guy… its complicated. He was dying and he kind of kissed me and then he wasn't… dying, not because I kissed him! But he says he doesn't remember it. I'm not really sure what that is all about. My boss is constantly telling me I'm not good enough though I'm not sure what his problem is, and…"

"Kara? Thank you for your help. Would it be okay if I stayed here on your couch tonight and slept while I wait for Sara?"

"Oh, of course. But I think you three should stay here until I can bring these people in. They sound like trouble, for you I mean. I can grab them…"

"Kara," Oliver interrupted. "I appreciate the offer but we have this. If you could use your vision to track them down for us…"

"I don't know, Oliver. This is my universe. Its nothing personal but since National City is my city and really, besides a couple days where I had to save your life, you are kind of an unknown in this situation. I would like to keep you at arm's length. You understand, right?"

"Barry said you didn't get angry much. I suppose he forgot to mention grudges." Oliver told her. "Sara brought up another point, Kara. It is possible that Shiva didn't get the weapons from the future and the Time pirate told her about the key in S.T.A.R.. If she is here now, that … there are other aliens here, right? You talked about the DEO you work with? Barry said he had been there before?"

"Yeah…"

"Are there weapons here that can hurt you? Or other Aliens? Weapons she could get her hands on? Because she can go back anytime as long as she has that key. The rest of Sara's team is waiting for her but if she has those weapons, she could slaughter them. If she is here, we have got to stop her from acquiring any arms she could take back."

Kara hadn't thought of that, the weapons Cadmus had provided the criminals with crossed her mind. There were definitely hand held weapons that could cause mass destruction in this city and though Lillian Luthor was in prison that did not mean Cadmus was out of business. The woman was certainly not talking. Even being held without bail, she had an army of lawyers in her back pocket and any attempt to extract information could ruin the case against her.

"Yes, there are definitely weapons here that she could use to cause a lot of damage, weapons that are from a lot of different planets. Look, it doesn't matter, just relax, lay down and sleep. Sara will find us in the morning and the three of us can talk about can stay in the hallway. Just don't bleed on my couch and let me take these gross, bloody towels away. Tomorrow is Saturday and I planned to walk or fly over the streets and figure out some story to give my jerk boss but… hey, this may make a great story! Supergirl takes out ninja weapons dealer."

"Great. So long as you understand she is coming back with us, dead or alive."

"Alive! You are not killing anyone on my Earth, Oliver Queen! I will send you back!"

"Between me, Sara and Mick I'm the best chance this woman has of going back alive."

Kara decided he was telling the truth… for the most part. "You want to change? I have some pajamas you can borrow…"

Oliver looked at her in disbelief.

'Nevermind then. Okay, do you need painkillers? I have some for the Holiday nights that Alex stays over because she has had too much to drink. She never has a problem except on Holidays. She is weird like that. Not grounded like I am…why are you looking at me like that?"

"I'm just hoping this is some surreal hallucination I am having. I don't need pajamas but if your sister has hangovers does that mean you might have alcohol here? Something stronger than a beer?"

"Yep, hold on." Oliver had a Vodka bottle in his hands in less than a second. "I had Tequila before Thanksgiving dinner but it disappeared. Mon El must have drank it."

"Montel?" Oliver asked, after taking a swig and downing half the bottle, then pouring a bit on his wound.

"Mon El. He was the one I was telling you about that kissed me when he was dying… drink more and sleep. I'll find you some clothes in the morning." Kara gave up, seeing his eyes glazing over as he finished the bottle in a second swallow. She moved to her room and threw a blanket over the man, then went to her bedroom. Kara briefly wondered how she would sleep with the events of tonight on her mind.

She was snoring within a minute.

At the busiest Alien bar in National City, Alex Danvers sat at the bar, annoyed. Maggie was supposed to have been here thirty minutes ago and all she had gotten was a text saying she was running late with no further information, despite Alex's questions. The two were… Alex wasn't completely sure where they were at. The night they had was amazing but hadn't gone far, other than kissing, drinking wine and falling even deeper for the cop. She understood this was new, new to her and most likely new to Maggie. Maggie had hurt her before but that was forgotten. Still Alex kept her guard up. She didn't want to, but she also didn't want to hurt. She was crazy about the woman and wanted this to work so badly any slight such as being late without a rational text explaining why, kept her on edge.

Her worry about being stood up was gone, replaced by another kind of worry, when Maggie walked in. The woman's face looked drained. She was obviously tired, not a look she had seen on the woman she might call her girlfriend.

"Hey, are you okay? Bad night?"

Maggie laughed. "Weird night. We got called to a gang fight in progress. It was… unique."

"Unique? What sort of aliens were you dealing with?"

"Aliens? I don't think they were aliens. Okay, one guy who had a flame thrower might have been an alien, but was most likely just a very unfortunate man in the looks department. I didn't get a good look at him. No, apparently we walked into a ninja fight."

"A ninja fight?" Alex asked doubtfully. "In National City?"

"Yep, complete with a flame thrower. We get a 911 call about a gang fight in an alley between people using swords and bows and one guy had a flame thrower. The other gang was using Katana and handguns, though there were only four shells found. One gun was found pinned to a wall through the trigger guard by an arrow of all things. Whoever made that shot had serious skill. So we show up and have both ends surrounded. I'm behind a car, wanting to avoid being hit by an arrow, tell them to put their hands up and one did. A fairly small woman in white, though I couldn't make out her face. She raised her hands and then dropped them, there was an explosion of bright light , a lot of smoke and they were all gone, ninjas and the flame thrower, some hooded guy and the woman. One of my officers swears he saw them flying to the roofs of the two buildings but a search turned up nothing. We did find blood on scene and are checking it for DNA but I doubt the results will be in soon."

"You should have called me." Alex told her.

"If it was aliens you would have been the first to know, but ninjas, that is probably more under the PD's jurisdiction."

"Maybe but Supergirl could have been there in seconds… what?"

Maggie shook her head. "You and Supergirl, you two are pretty tight, huh?"

"Yeah, we are. She works with the DEO and she did kind of saved the world not long ago. Why? Do you not like her or something?" Alex asked, a bit defensively.

"I don't know her. But you do. You know who she really is, don't you? I know you two are close, I know she must have some life that doesn't revolve around flying. How she stays under the radar, considering she doesn't wear a mask, I will never understand, but you do. Sometimes…"

"Sometimes what?" Alex asked.

"Sometimes it seems that… nevermind. Forget I said anything."

"No! Tell me."

"It just seems like the two of you are very close. Like you are in sync with each other. Honestly when I first saw the two of you together I kind of thought you were a couple."

Alex spit the drink she had been sipping on the bar.

"I'm guessing by your reaction that isn't true?" Maggie guessed hopefully. She would normally never admit that she was jealous of the hot blond in a skirt and tight top but she was at times. Who wouldn't be?

"Look, Supergirl and I work together. Our agency is very lucky to have her, considering her cousin refuses to work with any Government organization. Yes, I am one of the few people who know who she is and no, I will never say. We are close but we are friends, that is it."

Maggie nodded and took a long drink of her beer.

"Glad to hear it."

"Were you jealous?" Alex asked, somewhat amused and somewhat mystified. She expected Maggie to deny it.

"Yep." Maggie responded, too tired to lie.

"Oh… well there is no need to be. Hey, I can call her and when you track down these ninjas she would be glad to help. I have it on good authority that arrows, swords and flame throwers do not hurt her. She could help keep your officers safe." Maggie shrugged her shoulders.

"Maybe. I'll let you know if a gang fight breaks out again. You can call your best friend in blue."

"Maggie…"

"Kidding. Want to play pool? I was thinking tomorrow night maybe we could go on an actual date besides this bar, if you wanted to."

Alex heart warmed at that. "I would love to." This would be a step in the right direction. Alex knew where she wanted this to go and was pretty sure that Maggie wanted the same thing but this had to be slow. She wanted it to be right. The idea of being rejected again was definitely in the back of her head.

"Hey, listen, if you don't want Supergirl involved then could I at least ask my sister if she has heard of anything. She is a reporter and has a lot of contacts on the street." Alex lied. Though since Mon El was working as an alien enforcer for loan sharks, Alex supposed he did count as a contact.

"Your sister? The one who looked at me with that weird smile? I think she wanted to knife me. That was one creepy smile. I guess you told her about…"

"I tell my sister everything, most everything. I'll ask her in the morning."

"You mind if I come with you?" Maggie asked. "I'm guessing if you and your sister are that close and she looked like she wanted to murder me despite the creepy smile, I should probably get on her good side."

Alex shrugged her shoulders, agreeing that Kara probably didn't have the best opinion of Maggie since she disappeared for a few days after the two had come to some sort of relationship. Apparently her little sister decided she was homesick and went to the Fortress of Solitude or something. Kara was pretty evasive about her whereabouts but Alex didn't push. What she did with her time was her business.

Of course the big sister the blonde would crack eventually and talk.

"Sure. Bring her crullers and you are back in her good graces."

The next morning, after Kara had woken Oliver to inform him that she would be going out to buy him clothes for the day with the $100 bill she spied in the bottom of his quiver and offered the use of her shower, Oliver decided to take her up on the offer. Once assured the woman was still out and not feeling like dressing in his uniform, he walked into the kitchen for a cup of the coffee he smelt, wearing only a towel.

He was lost in thought about the situation, having no way to contact Sara, not knowing if they had found Shiva or not and the other recent events that occurred after Kara had left, mostly centering around inadvertently killing Felicity's boyfriend. Something told him the fact that he thought he was killing someone else would not be the best excuse for Kara to hear so decided if she asked what he had been up to, he would leave those events out.

Because he was lost in thought, he never heard the door unlock, but did here something drop. Turning quickly and reaching for a weapon, remembering he only was wearing a towel and trying to stay cool, he saw two women standing in the doorway. One had dropped what looked like a box of donuts.

Alex for her part was frozen, taken completely off guard, seeing a man in Kara's apartment, smiling and wearing only a towel around his waist. She wasn't sure what to do, thinking if someone broke into her sister's apartment, he wouldn't take a shower or be holding a fresh cup of coffee.

"Hi." Oliver tried, wearing his panted charming smile.

"Hi…"

"Can I help you?"

"Uh, yeah, maybe. I'm here to see my sister. My tracker showed she wasn't here so I thought I would use my key and wait for her but… who are you?"

"You have a tracker on your sister?" Oliver asked, wondering who does that.

"I think…I mean yeah, but not because… it's just she has a habit of getting into trouble, disappearing at weird times…"

"I see."

"I'm sorry, who are you?" Alex tried. Oliver's eyes were on the woman beside her. Both obviously knew how to handle themselves and the Arrow thought he recognized her from a brief encounter with the police last night. She must have been a detective as she had been in plain clothes with the other uniformed officers.

"I'm…" Before Oliver could think of a fake name, Kara rushed in, shopping bag in hand. She had heard the conversation from the lobby.

"Alex?! Hi! Uh… what are you doing here? And with Maggie… hi Maggie. This gets even better."

Both women took in the disheveled girl who stepped inside. To her absolute embarrassment and horror, Oliver stood next to her and wrapped an arm around her waist.

"Kara, you mean you didn't tell your sister about us? I suppose we have been a bit low key. My name is Oliver. I've heard a lot about you…Alex." Oliver finished wondering if Kara knew her sister kept a tracker somewhere on her, probably her phone. He remembered something about a DEO but his mind had been on Prometheus after the aliens had left.

"Yeah, no, I guess it slipped my mind… honey." Kara tried, wishing this was a nightmare and hoping gravity didn't defeat that towel. She didn't even have time to register the scars all over the man's torso. She just wanted Alex and Maggie to go. If it had been only Alex she would have explained everything. So of course Alex brought her cop girlfriend.

"Uh huh." Alex told her, recognizing the mortification on her sister's face. "So whats in the bag? Kind of early to be shopping, isn't it?"

"Oh yeah, Kara had to pick me up some clothes. Mine were…ruined last night." he told Alex with an evil grin, channeling his former playboy personna from long ago.

"Please make it stop." Kara whispered, thinking she may find this Shiva and give Oliver to her. "So whats up Alex? You usually aren't here this early. Everything… okay?"

Alex took her disapproving eyes off the scarred, half naked man and focused on her little sister who was red as a fire truck.

"Yeah, Maggie was wanting to know if your street contacts had heard anything about a gang fight last night? We were wondering, being a reporter, if you could talk to your contacts. Apparently there was quite the scuffle involving bows, arrows, flame throwers, swords… the usual. Think you could ask around?"

"Of course. No one was… hurt in this gang fight, right?"

Maggie shook her head. "One of the participants was bleeding but not enough to kill him or her. The ninjas disappeared in a cloud of smoke."

"Wow, that is unusual. I will get right on that. Check with my… sources." Kara offered, trying to move away from Oliver's arm, casually.

"I thought we were going dancing tonight. You promised to show me the city today, remember darling? Sleep in, breakfast in bed, a tour of the city, dancing and whatever else we might find to do?"

"My sister needs help. A tour of the city can wait, Don't you think, dear?" Kara finished, stepping on Oliver's foot, causing the Arrow to clench his teeth.

"Of course. I suppose I should get dressed. It was nice to meet you Alex, and I didn't catch your name?"

"Detective Maggie Sawyer. I don't mean to intrude but I carry a few scars myself. Could I ask you where you got all those? They look brutal."

Alex would have normally chided her for being intrusive but she was very interested in his reply.

"Skiing accident." Oliver popped out immediately.

"Skiing? Because it looks like a lot of knife wounds, almost like someone tried to gut you. Those look like gunshot wounds. A couple of them could even be small projectiles, like arrows. All that from skiing accident?"

"The slope went through a rough neighborhood." he offered, causing Kara to snort and cover it up as a cough.

"How long have you been a member of the Russian Mafia?" Maggie continued her interrogation.

"I'm not a member… that is sort of a random question."

"That tattoo on your chest is a Bratva tattoo, indicating the rank of Captain. If you aren't a Captain you could be killed for having it."

Oliver feigned shock. "I had no idea. I got drunk with a Russian friend who was visiting from Moscow and the next morning I woke up with this. She told me it was just a traditional Russian tattoo. Maybe she was setting me up to be killed. We didn't stay friendly long afterward. I guess I just hadn't found the right girl until I met Kara. I should really get dressed, unless you have anymore questions about my scars and tattoos?"

"I didn't mean to pry." Maggie lied poorly. She didn't know what was going on but she was sure of two things, this man was definitely not Kara's boyfriend and he was a very bad liar, no matter how charming he tried to act.

"No problem. Oliver is an open book. Sometimes I can't get him to shut up. Alex, why don't you call me later and we can maybe have some sister time? You can go with me when I talk to my… sources."

"Oh, you bet I will. Let me get these crullers off the floor and you can make sure your new boyfriend who spent the night is appropriately dressed. I'll see you soon. Very soon."
