A/N So i've been working on this story for a while now and i wasn't sure that i was going to post it because i didn't know if anyone would read it but i'll give it a try. So let me know if you want me to continue.

Background Info: (Grey's Anatomy info)

Lexie Grey is Meredith Grey's younger sister. She was in an on again off again relationship with Mark Sloan (who for the sack of this story is alive). Lexie, Meredith, Derek, Mark, and a few other doctors were in a plane crash. In Grey's Anatomy Lexie was killed during the plane crash but this is my take on what happened.

Alex Danvers hadn't always been Alex Danvers. She had a past that very few people in her life knew about, not even Kara knew everything. Before 2011 Alex, or as she was known at the time Lexie, thought she knew exactly what her life was supposed to be like. She was a doctor, working at Seattle Grace Hospital. She was finally starting to feel happy with everything that was happening in her life. Then just like the plane she and a few of the other doctors were on, everything came crashing down and her life was never the same after that.

Lexie Grey died the day the plane crashed and Alex Danvers was born. She would have really died if it weren't for Hank Henshaw and Superman. She owed them her life and so that's exactly what she gave them. She began training and working as an Agent for the DEO, a secret government organization whose sole purpose was to protect the planet from hostile Aliens. The DEO developed a whole new identity for Lexie, she became Alex Danvers. It was Alex's job to work closely with one Kara Danvers, to act as the young girls sister, while making sure Kara was safe and one day she fight along side her. But Alex developed more then just a friendship with the young Alien, they were no longer just acting like sisters, they were sisters.

Five Years Since The Crash

"Alex!" Kara yelled from her room. "I need food!"

Alex couldn't help but laugh at her little sister. "Kara I'll get you food on the way."

Alex leaned her head into Kara's room, she let out a laugh as she saw the pout on the aliens face.

"I need food now though."

"If you would have just gotten ready when I first came over you'd have food by now." Alex pointed out.

"Do we have to go?"

"Yes, this is for your work." Alex laughed again. She loved her sister she really did but sometimes dealing with Kara when she was hungry was like pulling teeth. "Come on."

Kara whined in protest. "Maybe Cat wont even notice if I'm not there."

"Cat Grant wouldn't notice if her left hand was missing but you, yeah she'd notice if you weren't there." Alex grabbed a pillow off Kara's bed and threw it at her sister. "Now hurry up our we'll be late and we wont be able to get you real food before we go to the party."

Kara caught the pillow and threw it back. "I shouldn't have asked you to come with me. Because then I wouldn't have to go."

Alex began to make her way out of the room. "If you didn't go you would be fired." She pointed out before closing the door and then yelled. "Hurry!"

"Happy?" Alex asked as Kara threw away the pot stickers container. She had a huge grin on her face.

"So happy." She laughed.

The two made there way into CatCo and then up to the floor that the party was being held on. "I'm going to go check in with Ms. Grant. You good?"

"Yeah." Alex nodded waving Kara off. "I'll be around when you have free time."

Kara gave Alex her usual contagious smile before walking away. Alex noticed Winn and James, giving them a polite wave but made her way over to the bar. She ordered a drink and then found an empty table that she could sit at and wait for Kara.

Alex had allowed herself to get lost in thought. Five years ago to the day her past, the person she used to be died. She thought back on everything she knew. Everyone she loved, Meredith, Derek…Mark. As well as the other amazing doctors she used to work with. She wondered what they were all up to. She wondered if Mark had ever found someone else. She still loved him and she hated that fact. She was now a completely different person, literally, and she could only imagine how much he had changed. She could never bring herself to look up any of the people from her past. She occasionally saw snippets on the news about some new and amazing medical procedure done at Seattle Grace, and occasionally the name of one of her old friends would be mentioned as well but that was the only time she allowed herself to find out what was going on over there. She tried her best to not even think about Lexie Grey. Lexie died in that plane crash, Alex Danvers is her life, Kara is her life.

"Earth to Agent Danvers." Came the familiar, annoying but familiar voice of one Maxwell Lord.

Alex looked up to see Lord standing there, he pulled out a chair and sat down. "I'm glad you finally snapped out of it, you were gone for a while."

"What do you want?" Alex asked not bothering to hide the fact that she didn't want him sitting there.

"Wow such a warm welcome." Lord smirked before taking a sip of his drink. "Where is it that you were just now?"

"Wouldn't you like to know." Alex scanned around hoping to find Kara or one of the guys so that they would come save her. Alex would rather be back in the plane crash then be alone with Maxwell Lord.

"Now at least the other times we've been around each other you at least pretended to be interested. What's eating you Danvers?"

"Max." Alex turned to the billionaire. "Now when I say this know that I mean every word okay. We aren't friends so leave me alone."

Alex went back to scanning the crowed, but what she saw was enough to cause her heart to start racing. She had to look multiple times to make sure that what, no who, she saw was real. Alex could vaguely hear Lord saying some sarcastic remark but she didn't much care to make sense of the jumbled mess. Now all she could think about was getting the hell out of there. There, talking to Cat Grant was none other then Derek Sheppard himself.

Kara walked up to Cat and handed her a drink before turning and was saying something to Derek. That's when she walked up and Alex knew there was no way it was just someone that looked way too much like Derek. Meredith… She looked so good. She looked happy.

Alex finally snapped out of it, unless she wanted to be compromised she had to get moving. She needed to somehow get Kara's attention without any of the others seeing her. Alex stood up, completely forgetting about Lord, and walked as far away from the two people from her past. She saw James and couldn't be happier about it.

"James." Alex rushed up to him.

"Hey Alex." James greeted with a smile on his face.

"I need you to do something for me and don't ask any questions."

James gave Alex a questioning look but must have decided to look past the weird request. "Okay."

"Go get Kara from me, tell her it's an emergency and I need to talk to her. But don't let any of the other people hear you." Alex instructed.

James gave her another questioning look but walked over in the direction of Kara, Cat, and the two people Alex could have gone without ever seeing again.

Alex waited, she could feel her heartbeat rising as she thought what she would do if either of them saw her. She would have to inform J'onn that she'd been compromised. What would happen after that? Would she be forced to relocate? Would she have to leave the only person that ever truly felt like family to her? In the short five years that she had gotten to be Alex Danvers, they were the happiest years of her life, and that's solely because of Kara.

"Alex are you okay?" Kara asked rushing over to her. Alex immediately pulled Kara behind a wall so that no one could see them.

"I'm about to be compromised." Alex informed her.

"Compromised? What do you mean?" Kara asked confused.

"Those two people talking to Cat Grant, they knew Lexie Grey." Alex told her, suddenly going very quiet, so quiet only an Alien with superhearing could hear her.

Kara's jaw dropped and she began to slowly shack her head. "No. I wont let that happen."

"Kara they are standing between us and the only exit in this room." Alex protested.

"We're going to figure this out Alex. I wont let them see you." Kara promised.

"What they hell are they even doing here?" Alex asked looking back out into the crowded room and spotting Meredith again.

"Ms. Grant invited them. I guess Cat knows a Dr. Bailey from Seattle Grace and something happened so here they are." Kara tried to explain but it was obvious she didn't know. Not that it mattered, all that mattered was Alex getting out of there before Meredith or Derek saw her.

"Bailey…" Alex said to herself. She couldn't help but smile at the thought of Dr. Bailey. She quickly snapped out of it. "Can you get Cat, Meredith, and Derek out on the balcony?"

"I can try." Kara nodded her head. "When you get out send me a text so I know you're good."

"Kara I love you!" Alex pulled Kara into a hug. This had less to do with Kara willing to help her and more to do with the fact that if things don't go well this could be her last chance.

"I love you too Alex." Kara hugged back. "Let's do this."

Alex nodded and watched her little sister walk up to her…her sister and brother-in-law. No, Alex they are no longer your family. You have a family, you have Kara and that's all you need. Lexie Grey is gone and with her so is her relation to Meredith Grey and Derek Sheppard.

Kara walked up to Cat and began talking to her, they didn't look as though they were going to move anywhere.

"Come on Kara…" Alex thought to herself.

Just then the group of four made their way over to the balcony and out the door.

Alex let out a huge sigh of relief. She began to casually make her way across the floor, not wanting to draw any attention to herself.

Just as she was going across the dance floor Maxwell Lord stepped in front of her.

"You owe me a dance." Lord stated very matter-of-factly.

"Umm let me think about that." Alex pretended to consider it. "No."

She tried to move around him but he stopped her. "Agent Danvers, you were really rude earlier so now you are going to make it up to me by dancing with me."

"Lord I don't have time for your crap. Get out of my way." Alex ordered.

"There you go again, being rude." Lord smirked. "I guess that's two dances."

"In case you don't already know if I really wanted to I could throw you half way across this room in the matter of seconds. Get out of my way." Alex glanced back to make sure that Kara was still occupying them on the balcony. Kara gave Alex a worried look before replying to something Derek had said.

"You wouldn't do that. You don't want to cause a scene." Max commented looking out at the balcony as well.

"Do you really want to test that theory?" Alex threatened. In that moment she couldn't help but think it would totally be worth compromising herself to give Maxwell Lord everything he deserved.

"I'll take my chances." Max grabbed Alex's hand and began leading her further onto the dance floor.

"Max I swear to god, let me go." Alex ordered in a deadly voice.

"Oh if looks could kill," Max laughed.

"If you want to be killed I can arrange that." Alex ripped her hand out of Max's. Alex glanced back to the balcony and her heart dropped into her chest. They were walking back into the room and headed straight for the dance floor.

"Kiss me." Alex demanded.

Lord broke into a smirk. "Well that escalated…."

But he didn't get to finish because Alex pulled into a kiss. She pushed him over to a place that no matter where Meredith and Derek were they wouldn't be able to tell who she was. But Kara knew exactly who it was and she couldn't help but feel extremely bad, and grossed out, but mainly bad that Alex had to resort to such measures.

Alex finally pulled away when she knew they had reached the door. In order to keep up the charade she gabbed Max by the hand and headed out the door with him in tow.

"Wow." Max grinned when they were out in the hall. Alex immediately released his hand. She felt the sudden need to bleach her mouth.

"Shut up." Alex said as she made her way over to the elevator.

"What was that about?" He was still smiling.

Alex walked into the elevator, Max tried to follow but Alex pushed him out. "Bye."

With that the doors closed, leaving a very confused Max Lord staring at where Alex had been standing moments ago. He just shook his head and made his way back to the party. He knew Alex had a thing for him.

Alex headed straight for the DEO. She had to tell J'onn about everything that happened.

"Where's Director Henshaw?" Alex walked up to Vasquez.

"He's in his office, Ma'am." She informed Alex.

"Thanks." Alex turned and headed straight for J'onn's office.

She knocked on the door but didn't wait for an answer, she just opened the door.

"We might have a problem."

Hank was looking down at a stack of papers but as soon as the words Alex had spoken registered in her mind, he looked up. "What do you mean?"

"Derek Sheppard and Meredith were at the CatCo party tonight."

It took him a second to understand what she had said. "Did they see you?"

"I don't think so." Alex said. "They talked to Cat and Kara for a bit but I don't think they ever noticed me."

Hank sat in thought for a moment. "Do we know how long they'll be here in Central City?"

"No idea." Alex sat down, not making eye contact with Hank.

"Are you okay?" Hank asked, he knew this day was always hard on Alex but then to add in seeing those two must have felt like her own personal hell.

"I hate this day." Alex stated. "I hate everything about it but at the same time it's the day that I got all of this. I got my little sister, I got the DEO, I got a new life that has made me happier then I ever was as Lexie Grey."

"Alex when you asked to work here at the DEO do you remember what I told you?" Hank asked sitting in the chair next to her.

"You told me that I would always have a home here but that my life would never be the same."

"Lexie Grey was a great person, but Alex Danvers is an amazing person. I know it was hard to see them tonight and I'm sure it took a lot out of you not to go up to them, but we're your home now." Hank pulled Alex into a hug. "And if you ask me I think I prefer Alex Danvers."

Alex let out a soft laugh. "I do too."
