Kara gasped and shot forward in bed; her heart pounding and her eyes wide with fear as she glanced around her bedroom panting.

"Kara" Alex said; her voice full of concern as she hurried towards her.

"Alex" Kara sobbed, wrapping her arms around her sister.

"It's ok, it's ok" Alex soothed "You were just having a nightmare."

Kara buried her face into Alex's shoulder, inhaling her scent. "It felt so real."

"Do you want to talk about it?" Alex asked, tucking a stray bit of hair behind Kara's ear.

Kara thought for a moment; the memory of it becoming foggy. "I dreamt that I lost you"

Alex took hold of Kara's hand "Well I'm here and I'm not going anywhere" she replied "Except into the kitchen because I really need coffee" she joked.

Kara smiled and couldn't help feeling a little silly.

"Do you want me to make you anything before I go?" Alex asked as she headed back in to the kitchen.

Kara glanced at the time "Where are you going so early?"

"I have some errands to run before work." Alex replied as she poured coffee into her travel mug.

"More errands" Kara smirked.

"What's with the smirk?"

"Nothing, it's just you ran errands yesterday and then again today. Anyone might think..."

"I didn't run any errands yesterday" Alex interrupted.

Kara frowned and glanced around her apartment; her eyes falling on the leftovers from sister's night.

"Are you sure you're feeling ok?" Alex asked.

"Yeah; I just have the strangest feeling of déjà vu"

Alex studied Kara for a moment. "Why don't you come by the DEO later..."

"Honestly, I'm fine" Kara interrupted.

"You're sure?"

"I'm sure" Kara smiled reassuringly.

Alex hesitated before picking up her travel mug and keys. "Looks like you have some errands of your own." she said nodding towards the TV.

Kara frowned and turned her attention to the TV.

"Don't be too hard on them" Alex said as she headed for the door.

"Alex wait" Kara almost shouted.

"What is it?"

"I don't know; I just can't shake this nagging sensation in the back of my mind."

"Which is?"

"Something bad is going to happen" Kara hesitated. "To you" she added.

"Kara, nothing's going to happen to me; you just had a bad dream, properly from eating way too much pizza and ice cream before bed." Alex's phone vibrated and she quickly read the message from Sam. "I really have to go." she took a step closer and wrapped one arm around Kara "I will call you later."

"Please be careful" Kara said as Alex headed towards the door.

Alex looked back, her face full of concern "You too."

Kara watched Alex leave her apartment before quickly changing and flying towards the high speed chase for what felt like the second time.

CatCo

"Earth to Kara" James said as he waved his hand up and down in front of Kara.

"Uh" Kara said, looking up at James.

James smiled "I said nice save this morning."

"Thanks"

"Are you OK?"

"Yeah, I'm fine" Kara replied, pushing her glasses back up her nose.

"Damn heel" Suzanne said as she limped past Kara and James carrying one of her shoes.

Kara frowned and watched Suzanne make her way over to the stationary cupboard in search for glue. "Top shelf, behind the box of markers" She shouted.

Suzanne retrieved the glue from the top shelf and waved her thanks to Kara.

"Man, I'd kill for your X-Ray vision" James whispered.

"I didn't use my X-Ray vision" Kara replied as she watched Suzanne apply the glue to her shoe. She glanced around at the others. "I swear I've lived through this day before."

"That déjà vu feeling" James said.

"Yeah; only I've been experiencing it all morning."

James raised his eyebrows and looked back at Kara.

"Don't give me that look" Kara said.

"I'm not" James smiled, raising his hands in surrender.

Kara sighed "I know something isn't right; I can feel it."

"What's your intuition telling you?"

"That Alex is in danger" Kara replied without thinking.

James frowned, he hadn't expected that answer.

"I know it sounds..."

"So call her" James interrupted.

Kara hesitated before picking up her phone and speed dialling Alex. "It's gone straight to voicemail."

"That doesn't mean anything is wrong" James replied reassuringly.

Dread settled into her stomach. "I have to go."

"Kara wait" James said but she ignored him.

Kara dialled Winn's number on the way to the elevator and he answered on the second ring.

"What up my favourite Kryptonian" Winn answered.

"Winn..."

"Ok, that sounded way cooler in my head" Winn interrupted.

"Winn listen to me, I need you to trackAlex's location."

Hearing the urgency in her voice, Winn sat forward and began typing on his keyboard. "Ok, that's weird."

"What is it?" Kara asked

"She's at base 49"

"What is she doing there?" Kara asked. She waited for the elevator doors to close beforeflying up through the hatch and out of CATCO.

"I don't know but..." Winn paused "How far are you from the base?"

"Less than a minute" Kara replied. "Why?"

"Ok, don't panic but we've just received Alex's distress call."

Kara's eyes opened wide and she pushed her-self forward; reaching the base within a minute. "Alex" she called when her X-Ray vision failed to scan through the lead walls.

"Alex is located on level 3 on the south side of the building." Winn said "J'onn and a team are heading your way now" he added as a loud bang travelled down the corridor to Kara's right.

Without hesitation, Kara sped down the corridor and into the examination room where she found Alex lying on the floor. She hurried towards her and fell to the ground beside her sister."Alex" she said, gently turning and cradling her in her arms.

"Kara" Alex swallowed and closed her eyes against the pain.

"I'm getting you out of here" Kara said, placing her arms under Alex.

Alex cried out as pain shot up through her body "Stop...please" she gasped.

A feeling of panic grew within Kara as she saw the extent of her sister's injuries. "It's ok; everything's going to be ok." Kara said as she fought to remain calm.

Alex fought to think through the pain. "It's Sam" She struggled to inhale enough oxygen into her lungs. "Reign..."

Kara glanced around the room but saw no sign of Sam. "Save your strength Alex, we will find Sam..."

Alex gripped Kara's arm "Sam is Reign" she forced the words out.

Kara frowned "That isn't possible."

"Sam didn't know...you have to...help...her." Alex suddenly coughed blood and the move caused pain to shoot through her torso.

"I have to get you to a hospital" Kara said, still cradling Alex in her arms.

Alex shook her head "It's...too...late."

"Don't you say that" Kara's voice broke as she struggled to stay in control of her own emotions.

Alex's eyes grew heavy and she struggled to keep them open as darkness swam before her.

"Open your eyes Alex" Kara shouted.

Alex forced her eyes back open and locked onto Kara's.

"That's it" Kara said "Keep your eyes open."

Alex smiled weakly; there was so much she wanted to say to her sister but words failed her.

"Please don't leave me" Kara sobbed.

Alex used what little strength she had left to rest her hand on the emblem on Kara's chest "Always wit...with...you." Her vision suddenly blurred and her hearing became muffled as her senses began shutting down.

"No no, no" Kara cried as Alex's eyes closed once more. She gently shook her sister but didn't get a response; Alex was gone.

Kara howled and sobbed as though her heart was being ripped in two. "I'm so sorry" she sobbed, wiping her tears from Alex's face.

"Kara" J'onn said as he and Vasquez entered the room.

"What happened?" Vasquez asked as she hurried to Alex's side.

"It was Reign" Kara paused as a sudden wave of guilt washed over her. "I wasn't fast enough."

"We need to start CPR" J'onn said.

Kara shook her head "That won't work" she replied suddenly remembering her dream. Images of the fortress, Jor El and the explosion flashed before her and she leapt to her feet with Alex in her arms.

"Kara, what are you..." J'onn began.

"I know what I need to do; I can fix this." Kara interrupted before disappearing.

"Kara" J'onn shouted but it was too late, Kara had already left the base and was on her way to the Fortress.

Fortress

"Kara Zor El" Jor El said as he appeared in the trophy room.

"What can you tell me about Lex Luthor's time machine?" Kara asked; her eyes fixed on the machine.

Jor El's hologram glanced towards Alex's body before turning his attention back to Kara. "The machine is not capable of sending you back in time Kara."

"You're wrong" Kara replied, she turned to face Jor El's hologram "This isn't the first time I've brought my sister's body to the fortress."

"What are you saying?" Jor El asked.

"I'm saying, this machine somehow reset time and I need you to tell me how to use it."

"The last time Luthor tried to use this machine he triggered an earthquake; that's why Kal El locked it inside the fortress." Jor El replied.

Kara thought for a moment "The explosion" she whispered. "My heat vision must have triggered the machine." she began examining the time machine "I just need to figure out how it resets...what the...let go of me."

"I'm sorry Kara but you've left me no choice" Jor El said as two Kryptonian robots dragged her away from the time machine.

"Jor El" Kara said through gritted teeth as she struggled to break free. "I'm doing this with or without your help."

"The risk is too great, I cannot allow it."

"Then you have left me no choice." Kara used her super speed and spun around on the spot; the move sent the two robots crashing across the room.

Suddenly eight more robots appeared and hovered above Kara.

"You really want to do this" Kara asked.

Jor El's hologram did not respond.

"Ok than" Kara said before filling her lungs and unleashing an icy blast at the oncoming robots. Three of the robots are blown backwards and smash into the wall before shattering into pieces. She took out two more with her heat vision before delivering a crippling blow to the sixth.

Suddenly the two remaining robots tackled Kara and pinned her against the wall.

Kara fought to break free as their tentacles wrapped around her limbs; she felt the tentacles tighten as she struggled against their grip. "Let me go" Kara screamed in frustration, unleashing a massive blast of heat vision.

The room exploded, turning her world to darkness once more.
