A/N: What's up guys? So, this is an idea I had after I watched 2x15 Exodus but I had already been writing These Broken Pieces and kinda shoved it to the back of my mind. But with spring break coming up I thought, what the heck let's do it. This is after Kara and Alex stop Lillian Luthor and prevent the exodus. I just don't think someone could come so close to losing everything and go back to normal in a day. So here's my little add on to the episode. Enjoy!

Alex couldn't stop thinking about it. She couldn't stop herself from replaying that moment in her head. Over and over and over again. The fear, the complete and utter terror that turned her blood cold. Almost physically feeling her hope slip through her fingers as the ship got farther and farther away from earth. From her home.

Alex had complete confidence in Kara, but as much as she hated to admit it, she had lost hope in her sister as they had reached the black oblivion of space. She thought there was only one outcome. She would be blasted across the universe, and Kara would die trying to save her. Her little sister would die because of the mistakes she had made. And the thought of having to live with that was more than even Alex Danvers could bear.

She honestly thought she had planned it all out, had every situation covered. She could get her father back, save the aliens, and stop Lillian Luthor, alone. She just knew she could.

Until she couldn't.

Until Lillian said there was no override code. Until her father came face to face with Cyborg Superman. Until the ship lifted off the landing pad. Until Winn couldn't find the information they needed to stop it. Until she couldn't disable the autopilot set to take them across the galaxy. Until she was about to lose everything.

Kara had sped to the front of the ship, cape billowing in the wind, the familiar "S" ("It's not an S, Alex!" "If that's not an S then what the hell does an S look like!") standing out in the center of her chest.

She remembers watching, helpless, as her little sister pushed against the gigantic ship, careful not to tear through the metal and release all the oxygen into the vacuum of space. She had told Kara to go, to leave, but Kara had shaken her head no, she had refused. She had almost been glaring, her eyebrows pulled together, her eyes fiery, and her jaw set. Kara had given her a look that screamed, "I won't leave you."

But Alex could see the fear in Kara's eyes, the fear of not being able to save the person she loved most, the fear of not being enough.

So Alex had placed her hand on the window. On the thin, fragile barrier keeping her sister from her, reminding her that Kara was so close, yet so impossibly far away. Kara's face had fallen, her doubt and heartbreak showing for a split second. And during that split second, Alex saw the lost thirteen-year-old girl that had come to her home years ago. The thirteen-year-old girl who lost everything.

Kara had met her hand with her own, pressing against the glass as hard as she dared, wanting desperately to be able to touch her older sister but knowing she couldn't, and may never get the chance to again if she failed.

Alex remembered shouting at Kara, saying, "You can do this," because she couldn't let Kara's last memory of her be of a scared, defeated little girl who was so desperate to save her father that she endangered everyone else around her. And maybe there was a small part of her that refused to give up hope, refused to believe this was the end.

Kara had so much strength, had screamed with the sheer force she was using. But when the small countdown clock on the ship had reached ten seconds, when the ship still hadn't stopped, Alex thought it wouldn't be enough.

She stared at Kara, trying to memorize every detail of her before she was launched across the universe. Her brave face, her sad yet determined eyes, her clenched jaw, her shaking muscles. And even if she couldn't save her, Alex couldn't have been more proud.

As ten seconds turned into five, Alex thought of all of the people in her life. All her friends and family. All of the people she loved. And all of the things she would miss.

How she would never get to prove to her mom that she could in fact bake a better chocolate pecan pie than her.

How she would never get to make up for lost time with her dad, take him to her and Kara's favorite restaurants and new movies like she had fantasized she would do for years if she only had the chance.

How she would never get to set up an online dating account for J'onn like he had threatened to do to her when she was single and stayed at work too long.

How she would never get to take Maggie to the roof of her apartment building on a moonlit picnic she had been planning for weeks for their three month anniversary.

How she would never get to apologize to Kara, tell her that she hadn't meant what she said when she told her little sister she wasn't part of the family.

Because in these last five seconds Alex realized what exactly her words meant to Kara, realized why Kara had been keeping her distance for the past few days, realized that she had done something she swore she would never do.

She made Kara think that her sister, who had promised to never abandon her, had left her alone and had lied to her every time she said, "I love you."

And that was one of the biggest regrets Alex knew she would have once she was gone. Kara would never see her again, left thinking that Alex hated her. And one of her scariest impossibilities was suddenly very, very real.

And then it wasn't.

And then the ship had stopped moving. And then the timer had stopped at two seconds. And then Kara had stopped pushing. And then everything had just stopped.

Kara had fallen against the ship in exhaustion, her forehead pressed against the glass. Alex looked at her with clear admiration and pride in her eyes as Kara stared back, relief and love shining in her own.

Everything after that had been a blur. Kara gently taking them back to the ground, the ride back to the DEO. She vaguely remembers being taken back in an ambulance instead of a standard DEO car, J'onn's orders. Remembers Kara sitting next to her, holding her hand as lights were shined into her eyes.

She couldn't focus on anything. She heard voices, but they were muffled, like she was underwater. Everything around her was too loud, but too quiet at the same time. Everything so sharp her eyes hurt, but it was also impossibly blurry.

The only thing she could think about was the last five seconds in the ship. How purely afraid she felt. And those last five seconds played on a loop inside her mind. Over and over and over again.

Later, J'onn and Dr. Hamilton would tell her that she had gone into shock and passed out.

She regained consciousness back at the DEO, in a hospital room. Alex glanced at the clock, it was 3 a.m. She felt something warm enclosed in her hand. Kara was asleep next to her, her hand still in Alex's own, with her head resting on the white bed. Alex smiled fondly at her, and sat up slowly.

The door suddenly opened, letting light into the otherwise dark room. J'onn walked in and closed the door quietly. When he turned around and saw Alex, awake, his eyes lit up, but his mask was quickly slid into place, "Agent Danvers,"

"J'onn," Alex replied, her voice gravelly. He gave her a glass of cold water, which she gladly accepted.

"You disobeyed direct orders, withheld enemy information, and infiltrated a hostile base without authorization. Care to explain your actions?" J'onn asked, his voice serious and angry, but concern was evident in his tone.

Alex bit her lip and looked away from J'onn, trying to contain the flood of emotions building inside of her. J'onn's eyes became sad as he asked, much quieter and softer than the first time, "What happened, Alex?"

Alex looked down and sighed, then stared up at J'onn. "I'm sorry, I just…I wanted my dad back so bad. I thought I could convince him to come back with me. And it worked. He really did do everything for family, for the right reasons. But his actions were wrong, and I got him to understand that. He didn't have to protect us anymore. But then the whole thing went to hell. A-and I don't know if I could've handled it if…"

J'onn's face softened. "Alex, talk to me."

She swallowed the lump in her throat. "I'm scared, J'onn. I keep reliving those final moments. I was terrified, and I can't help but think…what if Kara couldn't stop the ship? What if I really did lose everything?"

J'onn sat down on Alex's other side and placed a comforting hand on her shoulder. "Don't think about the what ifs. They will keep you up at night. They are best left in the past. Believe me, I know. You're right here. You're safe. You're with people who love you. And you're not going anywhere without us."

Alex's eyes started to tear up as she listened to the words of the man who had become her second father. She nodded at J'onn, a silent thank you, and they sat in silence for a moment. J'onn glanced at Kara and let out a small chuckle.

"And do you really think Kara would have let you get away from her that easy?"

Alex smiled down at her little sister, and even though J'onn already knew, he could see how much Alex truly loved her.

"No. No, I guess she wouldn't."

A comfortable silence overtook them once more as they looked at Kara. A thought suddenly occurred to Alex, and her eyes got wide as she startled upright. "How long have I been out?" Alex asked, looking over to J'onn.

"Relax, Agent Danvers," J'onn said her name almost teasingly. "We arrived at the DEO around midnight, it's only been about three hours," he looked back at the sleeping figure clothed in blue and red.

"She's been here ever since we got back. I tried to get her to go home and get some rest, but she refused to leave your side. She tried to stay awake as long as she could, but she fell asleep about twenty minutes ago."

Alex felt guilty at these words and stared at Kara's sleeping face. Her sister, who she had made feel unwanted, had waited for her to wake up even though she had to be exhausted.

J'onn looked at Alex, who was deep in thought as she stared at her sister, and decided she needed some time alone.

"I'll let you get some rest too, and don't even think about sneaking out," he said, eyes shining with amusement. Alex had the decency to look sheepish. J'onn knew her too well.

He gave Alex a meaningful hug and started to leave. He paused at the door, hand on the handle, and after a moment turned his head toward Alex.

"You know, maybe you should talk to her about this. About what you felt in the ship. Because if anyone could understand, it's her."

And then he was gone.

A/N: Um yeah this little add on turned out longer than I thought. In case you couldn't tell, there's gonna be another chapter to this. I know most of my stories are slow, but I want to convey as much detail and thought I think the characters would have as possible. Kara and Alex talk in the next chapter, hope you liked this start!

Can anyone tell what I got the title of this story from? Until next time, see ya!
