She opened her eyes startled, everything around was dark, barely being able to distinguish some rocks, it looked like a cave.

She stood up ready to find a way to escape from that place, however, as soon as she stept outside of that dark part, three dark figures appeared in front of her so she couldn't keep walking.

"Hi, little one" Selena kneeled in front of her. "Are you ready?" the woman asked reaching out to caress her face, but she moved away. "Okay, come on" the dark Kryptonian grabbed her arm and pulled from her to start walking.

Selena left her in the middle of the cave, the three witches around her as she observed them scared, not really understanding what was happening.

"She's a child, Are you really going to kill her?" she heard another voice, a man, so she looked around only to find him sitting with his back resting on one of the rocks. "She's the child of the prophecy, I don't think Jindah's plans were this" he commented.

"She's the one who would revive Reign, her life means nothing, plus she a Child of the Light" Selena said before returning her attention to her.

At that moment she stared at the woman scared, they wanted her dead and she wouldn't be able to even fight back.

Fear seized her when she saw one of the witches handing Selena a sword, moment in which she couldn't avoid crying while walking backwards, but being grabbed by the other two witches.

"Don't worry child, it will be quick" Selena told her.

"No! No! Don't do it, please" she begged as she tried to get rid of the grip, tears streaming down her cheeks.

"Hold her still!" the woman exclaimed, feeling how they tighten the grips.

She closed her eyes not wanting to see her death coming, only asking for it to be as fast as possible so she would be reunited with her mom. She was ready.

"What do you mean 'they took her'?" her sister asked confused as she paced side to side of the room, everyone else staring at her.

"They, the Children of Juru, took her" she answered stopping for a few seconds before starting walking again.

"But she wasn't with them when they came here" that time was Winn who spoke.

"Of course not, I don't know what were their plan for Halley, but I know it's not a good thing" she looked at her best friend.

She was mad at herself for had letting them to take her cousin so easily and at that moment she couldn't do anything to bring her back, which was starting to stress her because she couldn't stay there knowing that Halley was in danger.

She still remembered Selena's words when she had asked about her cousin's whereabouts, 'she's gone', those words had managed to broke her heart in multiple pieces as she truly believed that something bad had happened to the child. Something from she hadn't been able to save her.

"We're gonna find her, she's a fighter" Alex sat up to approach her. "You taught her well, Kara, she will be fine" her sister embraced her as she nodded thankful for her words, but not knowing if they were truly right.

"I put her in danger, Alex" she blamed herself again, her sister increasing the strength of the hug as she tried to contain her tears.

"No, you didn't" Alex pulled her away, but she just shook her head before walking away from the room.

She looked for a place where she could be alone, sitting in the room where her mother's hologram was, tears starting to run down her cheeks as she kept wondering how her cousin would be at that moment.

She turned her head when she heard the door getting open, her mom stepping inside the room while observing her, so she tried to wipe her own tears and pretend that she was okay, even if she wasn't.

"Alex is right, you know" her mom told her, sitting besides her. "Halley is a brave child because of you, Kara, you gave her hope, she knows you're looking for her" tears were impossible to control while hearing her mother's words. "You've become a mother for her, and that fear you have of something horrible happening to her is the same one I had when I put you inside that pod, or the one I will be feeling now knowing you're fighting out there" her mom explained while looking directly into her eyes.

"She's so little... She has suffered so much" she sobbed as her mom hugged her. "I need her to be safe..., I can't stay here without even knowing what they are doing to her" she admitted in just a whispered.

The both of them stood there hugging at each other as she kept crying, trying to calm down, so she didn't doubt to stand up when she got it, her mom observing her confused.

They needed to keep fighting, to save Halley, Sam and the Earth from the Worldkillers, she wouldn't stop until getting it.

However, before doing so she needed to talk with Dev-Em, let him know what was happening, so she walked to his cell with her mother following her close.

"Hello, Kara Zor-El..., Alura?" Dev-Em came closer to the glass. "How is that you're alive?" he asked.

"Dev-Em" her mom greated. "Argo survived"

"It's a long story" she sighed not really knowing how to tell him that the witches had kidnapped Halley.

"What happened? Where's Halley?" Dev-Em asked sensing that something was off. "I've heard what happened today" he said.

"They took her" she finally whispered. "Did you ever hear something...?" she didn't have time to ask, Dev-Em had already answered her by nodding.

"There was a prophecy about a child who would revive the most powerful worldkiller, which is Reign" he explained as her heart skipped a beat. "It's a sacrifice" Dev-Em looked away, she could see tears forming in his eyes.

"Maybe we still have time" she said trying to sound optimistic, though she knew that it was barely possible.

"I don't know, Kara, just try to bring her back" he asked as she nodded, she would.

Knowing that Halley could be dead or almost, had giving her strength to keep fighting, if she still had a chance for her baby cousin to be alive, she wasn't going to miss the opportunity of saving her.

However, the moment she heard Lena explain that Reign's cells were getting stronger, her heart sank, the possibility of her cousin being alive left her hopeless.

She held her head in her hands trying to calm herself down, her baby cousin couldn't be dead, the image of a sacrifice appearing in her mind as silent tears were welling in her eyes, so she walked away not wanting to be asked.

The terraforming had taken so many lifes from innocent people, even from a close friend, M'yrinn, who had sacrifice himself to save the planet, so she couldn't avoid embracing J'onn along with Alex when he returned.

She was distracted. Not really being able to focus on something, but her gaze diverted to Imra when she heard her speak, the Legion of Superheros had come to the rescue.

"Where's Halley?" Saturn Girl asked directly, maybe because she hadn't seen her or because she felt that something was wrong.

"They took her away" answered Alex as she felt the urge to start crying.

"What? Why?" Imra questioned confused.

"For a sacrifice" she whispered getting everyone to look at her, only her mom knew it from before.

"What?!" her sister exclaimed as everyone else stared at her, so she tried to walk away again, but Alex grabbed her by the arm.

"Don't, just don't" she begged not even looking at her, she didn't want to talk about it.

Her sister didn't say anything, Alex just take her to a private room where they could be alone, but she sat down in one of the chairs with her head down without being ready to answer any of the questions.

"When did you learn about that?" her sister asked sitting besides her.

"Dev-Em told me" she answered in just a whispered. "Reign is alive, she's dead" tears rolled down her cheeks.

"Maybe they didn't..." Alex started talking, but she shook her head. "We can't lose hope, Kara. You never lose hope, she needs you to keep fighting" her sister held her hand in hers as she closed her eyes before nodding.

Alex was right, her baby cousin needed her to keep her fighting, at least to do justice for everything that was happening, fo what they were doing to Earth.

"Hey, girls, I have a location" Winn knocked in the door.

She stood up ready to action, ready to end with all of that, most importantly, ready to kill Reign for good.

She walked inside the cave along with J'onn, Mon-El and her mom, her eyes locking with Reign's, knowing that everyone there had a target and hers was the Worldkiller.

However, even though she was prepared for the battle, fighting Reign wasn't as easy as she had thought it would be because at that moment the Worldkiller had managed to held in a headlock, choking her.

"Halley" she whispered relived when she saw her mom walking towards her while holding the six year old by the hand.

She could find fear in her cousin's eyes as well as in her mom's when they saw the scene that was happening in front of them, not being surprised when her mom and Mon-El ran toward her, but all of them falling because of Reign's scream.

"You cannot win" Reign told her. "There is no prison you can build that can contain me. There is no one on this planet of equal power that can kill me" the Worldkiller tighten the grip.

"That's what you think" she heard Sam's voice before feeling how Reign loosed the grip.

She hit Reign to let her fall into the hole, but observing with horror how the Worldkiller used her heat vision, a scream escaping her throat when she saw her cousin's being hit as well as Mon-El, Sam and her mom.

"J'onn" she called him fighting her own tears while approaching them.

"Supergirl, Mon-El gave his life to save me" he said as she looked at his dead body, Mon-El had tried to save Halley too. "All that time I spent with my father, I'd learned nothing. I still came in fighting like a Manhunter" J'onn commented.

"No, this is my fault" she shook her head. "I came in here ready to kill her, I knew I should have found another way" she blamed herself. "I... I've lost track of what I stand for. What have I done?" she asked herself, her hand gently caressing her baby's cousin face, the kid was so cold. "I'm gonna bring you back, baby girl, I promise" she promised taking Mon-El's rign while looking to the Harun-El. "Alex" she called her sister.

"Supergirl, did Sam get there?" Alex asked.

"She did, but I screwed up. I need you to find me a disruption" she told her, but her sister seemed to doubt. "I need to go back in time, like the Legion" she explained.

After convincing her sister and her best friend that she could do it, they found a disruption for her, flying to the space ready to go back in time, to save all of them.

When she went back in time, she held Reign before asking Mon-El to throw her the Haru-El, holding it even though it burned, but not giving up until the three of them were teleported to the Fountains of Lillith.

Once there she let Sam to handle the situation, letting her friend to end with her darkest self, not being able to contain a smile when she saw how the Worldkiller was forced to drink from the water before fading in front of them.

Everyone were near them when they woke up, but she could only look for one person, Halley, wrapping her arms around the child to bring her closer, practically obligating the kid to sit down on her lap.

Her cousin started crying while hiding her face in her neck, the two of them hugging at each other as tight of possible as if they were scared of what would happen of they stopped doing so.

"You okay, baby?" she asked pulling her away, observing the cut in her face and the one in her right hand, which seemed to be healing.

"I was scared" Halley admitted in just a whispered.

"I was too, but now you're safe, I won't let anyone hurt you, kiddo" she kissed her forehead before embracing her again, a smile in her face happy that everything was over.

"What does Halley want for her birthday?" Mon-El asked her as she sighed.

"Well, she wants a dragon" she answered as he laughed. "But that's impossible" she chuckled.

"Maybe a lizard" he said as she shook her head.

"No..., not a lizard" she laughed. "But she's been asking for a puppy" she looked at him, not being sure if it was a good idea, but Halley had been really asking for one recently.

"What are you doing?" her baby cousin asked approaching them.

"Nothing, kiddo" Mon-El answered. "You told me that you wanted to show me something, right?" he asked to what the child nodded while grabbing his hand before walking away.

She smiled observing how the child was laughing out loud because of Mon-El's tickles, which made her think about how her baby cousin would react to Mon-El having to leave.

She had learned a few nights ago, but he had decided to stick around for a little longer so he could be at Halley's birthday and she knew that it would be really important for her cousin, though she also knew that the child would be heartbroken after learning the news, but until then they shouldn't think about it, just live the moment.

Season three finished! I still have to publish another one with Halley's birthday and Mon-El leaving.

I think I will write season four, there are so many scenes for Halley to be in.
