A/N: This is a new story that started with wild Sanvers conversations over at Twitter. Let me know what you think!

Thoughts = bold/italic

The Department of Extranormal Operations (DEO), located in the heart of National City, is widely known for protecting the general population from rogue alien attacks. It's also known for having many legends within its ranks. One of those legends is Agent Alexandra Danvers, Supergirl's bad-ass adoptive older sister. For years, she has repeatedly protected the identity of her sister, as well as her life.

Another thing that was widely known is the fact that Alex Danvers has no time for a "personal life," and not for lack of trying. But she has sworn to put aside her personal goals to make sure the DEO was victorious in the protection of National City and its citizens, regardless of what planet they came. Sure, she once had time to imagine a life with the ones she loves, a perfect little life that now was just an unreachable dream. It used to be a reality, with a full name, filled with vegan ice cream and kisses jam-packed with promises of endless love. But she made sure that beautiful dream came to an end. You see, she was engaged to that beautiful creature, to that perfect woman who made her the happiest human being in the entire galaxy. Her name was Maggie Sawyer, and she made the stupid mistake of letting her go.

And here Alex Danvers was, starting another year regretting her rash decision for the millionth time, buried in paperwork from their latest case. Staring blankly at the report she was currently reviewing; her mind wandered back to better times, the ones where Maggie was still part of her life. It has been almost a year since she let Maggie walk out of her (their) apartment and her life.

"Eleven months, 12 days, 3 hours, and counting", she whispered under her breath. Closing the file, the agent gave up trying to finish her paperwork. Looking at her watch for the fifteenth time that evening, she finally decided to call it a night. Organizing the stacks of paperwork on her desk as best as she could, she stood up from her chair, reaching for her leather jacket hanging on its back.

Walking out of her office, she noticed most of the agents walking with a sense of urgency towards the meeting room. Gazing around, she spotted Winn organizing his desk and getting ready to head over to the meeting.

"Hey, what's going on?"

Winn turned around, looking troubled, "Cadmus apparently just assassinated Director Cameron Chase from the Gotham DEO."

"What?! Where the hell was Batman?! I thought he was keeping a close eye on her", Alex said looking around, trying to find J'oon.

"Apparently Batman and his sidekick haven't been in town for a while now. Batwoman was covering for him, but Chase had her secretly executed for I don't know what reason. Director Chase was a weird woman."

"I didn't know that," Alex whispered, knowing full well how Batwoman worked closely with the DEO and Supergirl, "Kara is not going to like that, she admired her."

"I know. Anyway, J'oon wanted to talk to you in his office, don't ask me about what", Winn said smirking, "I bet that he'll send you to Gotham."

The agent looked at him menacingly, "Don't you start with those rumors, and you know my dislike for that city."

Winn laughed, "I know, but who knows what's going to happen now. With no active vigilante helping GCPD, the city is a mess."

Alex rolled her eyes, "You have a good point there. I'll catch up with you later, going to see what J'oon wants."

"Copy, Boss," Winn joked.

She slowly made her way towards J'oon's office. After her conversation with Winn, she had a vague idea of what J'oon may want to talk about. Stopping in front of his door, she gently knocks, waiting for a response from the Martian.

"Come in, Alex," he says from inside the room.

The agent opens the door and walks inside, closing the door behind her. "You wanted to see me, J'oon?"

"Yes, I did. I'm pretty sure that you just heard the news about Director Chase."

"Unfortunately, I did," she walks closer to his desk, taking a seat on the chair across from him, "And about Batwoman."

"Yes, that as well."

"Why did Chase kill Kate? Was she out of her freaking mind?!", Alex exclaimed, crossing her legs.

"From the intelligence gathered about that operation, Cadmus apparently got a hold of Batwoman and performed some experiments on her. They had her under their full control. She attacked the DEO and Chase had no other choice but to shoot her down. She didn't want to kill Kate Kane. She saw her as a big ally and a friend."

"Some friend she was. Ok, so why you wanted to talk to me? I can say that Chase received a good dose of karma for what she did to Kate."

"Stop the sarcasm, Alex. She was doing her job", J'oon growled.

"Ok, I'll back off a bit. I still don't like what Chase did. They could have tried finding another way. So, why you called me in here?", Alex calmly said playing with her left ring finger, stopping when she noticed what she was doing. After all these months, the absence of her ring still felt odd.

J'oon sadly smiled, "Well, Gotham needs a Director and who else but you to become interim director while the position gets permanently filled."

Alex looked at him in shock, "You want me to leave you and Kara here, unattended."

"We will be fine, and it's not like we can't fly from time to time to see you," J'oon joked, proudly smiling when Alex returned the smile.

"That is true. But I'm pretty sure they have a good deputy director over there. Why the need for me to cross the town line into that dump."

"They do, Alex. But there is something else you need to know. They need a good agent to take on the vigilante side of the house."

"Vigilante?! But they have Batman and his sidekick. Of course, missing in action after the Joker killed Batgirl.", Alex asked confused.

"True, but I was talking about Batwoman."

"What are you talking about? Kate is dead."

"The Gotham City DEO needs an experienced agent to take Batwoman's place, as Batwoman."

Alex looked at him with confusion.

"Alex, you're the only agent that could pass as Batwoman and fill her shoes with dignity."

The agent started laughing hysterically, "Are you shitting me?! You want me to magically suit up as Batwoman, with no experience with whatever gadgets she liked to use, on a leather outfit that left no room for imagination."

J'oon smiled, "No, I'm not. And you could be trained to use all her toys."

"You want me to dress as Batwoman, to play vigilante at the same time as acting-Director of the DEO."

"Yes"

"To go around the city pretending like 'I'm the night' and protecting it from petty criminals. Did I already mention the leather suit?! J'oon, they have a Police Department to deal with those petty criminals! I'm supposed to fight rouge aliens! I'm a Federal Agent, not a superhero."

"And you also must protect the world from Cadmus," J'oon said, playing with his pen.

"Yes! Of course, that too! But I can do that as a Federal Agent."

"Cadmus is in Gotham; they are the reason Chase and Kate are dead. This assignment is not a permanent set-up, Alex. You can go back to being Alex Danvers after Cadmus is off the streets."

"But the suit, J'oon. So uncomfortable", Alex whined.

"Like that has stopped you before", J'oon joked.

Alex looked at him in defeat, "Fine, I'll do it. But I have Kara visitation rights."

J'oon laughed, "Yes, you'll have them. You can even set up a schedule with Kara before you depart to Gotham. I know better than to get in the way of your sister nights."

"You bet. You don't want a grumpy Supergirl while I'm gone", Alex smiled standing up from the chair, "Anything else I need to know?"

"Yes, you're taking Winn with you. He can help you get a basic understanding of Batwoman's gadgets and equipment. All of her equipment is currently stored at the Gotham DEO Headquarters. Also…", He said, opening one of his drawers and handing her a set of keys, "…here are the keys to your new apartment. It's near the Gotham Mercy General Hospital, in the Burnley District. You're on apartment 1, fourth floor."

Alex smiled, "Thanks. At least I'm near the hospital in case I get shot like I always do. How far is it from the DEO?"

"A couple of blocks. You can walk back and forth. As for your meetings at the City Hall and the GCPD, you'll be needing transportation because those are located in the Old Gotham District."

"Ok, that's manageable. Does the DEO work cases with the GCPD?"

"They do, they work very closely with the Science Division," J'oon said nervously, "Anything else you want to know?"

"Yes, do I have to move my stuff? I mean, from my apartment?", she asked, playing with her keys.

"No, the apartment is fully furnished. Kara helped us take care of that."

Alex started laughing nervously, "Kara knows?"

"Yes, she knows. Had to ask her permission before making this move, Alex. Your sister is rather persuasive."

The agent smiled, "That she is. Thank you. Knowing that she was part of this process calms my nerves a little. Does she also knows about the Batwoman fiasco?"

"Unfortunately, she does. She was the one that found her body and almost killed Chase herself when she did. We told her not to tell you about it. I wanted to handle the news myself."

Alex closed her eyes, trying her best to keep her emotions in check. "That's good to know. I would have tried to kill Chase as well, so I don't blame my sister. Thank you, J'oon."

"Before I forget, Winn will be traveling tonight to Gotham to get everything in line for your arrival. He will have an apartment in the same building as you, that way you two can have each other's backs. Gotham is a wild place."

"That I know," Alex said, "It's good to have someone familiar in the city."

J'oon sadly smiled at her, nervously looking around the room. The agent looked at him suspiciously, knowing fully well the Martian was hiding something from her. "J'oon, what aren't you telling me?"

"Well, Winn won't be the only familiar face in Gotham."

Alex walked back to the chair and took a seat, "I'm listening."

"You as the Director will have daily meetings with the second in command of the Science Division to make everything is running smoothly in all active joint cases."

"Ok, but that is not answering my question," the agent crossed her legs, waiting for a straight answer.

"That second in command is Lieutenant Maggie Sawyer," J'oon sadly said, waiting for Alex's reaction. The agent silently stared at the Martian, in pure shock.

"Maggie," she slowly said, "My Maggie."

J'oon slowly nodded, anticipating the agent to snap at him or bolt out of the office verbally. But Alex just looked around the room, trying to figure out what to say. He certainly was not expecting that reaction from the agent.

"Alex?"

"Good conversation, J'oon," she said standing up, "What's my report date?"

The Martian looked at her in confusion, trying to figure out what just happened. "Three days from today. Is that enough to pack and get settled?"

"Yeap, more than enough. I'll go home and get to it", she said walking out of the room, pulling the door shut.

"That is not what I expected. Humans are weird", J'oon whispered. He was starting to question his decision. He hopes Alex could manage to work with Maggie once again, at least for the short time Alex was staying in Gotham.

Alex sat quietly on her couch, nursing a glass of scotch. After getting home, she packed most of the stuff she needed in Gotham, deciding on only taking clothing and the essentials. After what J'oon told her, she figured that her stay should be kept short for the sake of her mental sanity.

"That second in command is Lieutenant Maggie Sawyer."

J'oon's words kept echoing inside her mind. Maggie was in Gotham, she was going to see her every single day, and she was working with Maggie once again. Like the good old days. This assignment was going to be pure torture.

She looked down at her drink, slowly moving it around to mix the watered down liquid and taking a sip. Opening up her other hand, she stared blankly at their engagement rings.

"I want you."

She could still see Maggie's teary eyes, how broken she looked. She did to her what she swore she would never do, hurt her. She hurt her because of an issue they didn't talked through like you're supposed to do in a relationship. If they had, they could have found a solution. Now, Alex knows there were other ways she could have handled it, and she decided for the most comfortable way out, breaking both of their hearts.

"And that is all my fault," a lonely tear ran down her cheek. She closed her hand, taking in the sensation of the cold metal against her skin. Alex perfectly knew that it wasn't going to be easy, but she had to face Maggie sooner or later. Her mind started wondering again, imagining how their first encounter would go.

Will she be glad to see me? Did she move on? Or does she still think about me as I do? Her thoughts started to overwhelm her. Now she realizes that canceling sister night with Kara was a bad idea; she could have used the sister banter right now to keep her mind occupied. It was too late now; she would have to try and get some sleep. Tomorrow, she was heading to Gotham, to her temporary new life.
