Miles away from the DEO, dessert plains outside National city.

Once Supergirl was sure that she was far away from the DEO base, and National City, she turned and floated in the air as she watched Jeremiah streaking towards her. The blonde took in a deep breath before she leaned forward and fired her heat vision at the streak heading towards her. She then started to fly towards Jeremiah while still firing her heat vision, Jeremiah deftly avoiding those shots.

Screaming, Supergirl managed to hit Jeremiah who used his arms to block the rays of high intensity light from her eyes. Taking the advantage, the flying Supergirl punched Jeremiah, who was thrown back and landed on his back with a thud.

"Dad!" exclaimed Supergirl as she landed and stood on the ground while watching Jeremiah closely. In her heart she knew that this wasn't her adopted father, he had attacked her, and attacked Eliza, but Supergirl still hoped against hope that the real Jeremiah was somewhere in there, "I need you to remember. It's me, It's Kara… please, stop. I don't want to… oof!"

Supergirl covered her face when she was hit by Jeremiah after he dashed towards her. She was flung back before she defended herself and then punched out at Jeremiah. Jeremiah continued to brutally attack Supergirl at high speed for several seconds, all of his punches connecting before grabbing the young woman and then slamming her into the ground. She would then get up, only to be kicked back down by Jeremiah. Supergirl then flew low towards Jeremiah, taking him of his feet by grabbing his left leg, and then slammed him into the ground after a mid-air turn. As he got up, she flew towards him, and landed a punch across his jaw. However, all that resulted in was Jeremiah roaring at Supergirl as his eyes turned black. Supergirl looked at the creature's eyes before she flew backwards, and then she flew forwards before slamming her shoulder into Jeremiah. She was screaming at Jeremiah to say something, to remember her. All the while she rose into the sky with Jeremiah on her shoulder, her face wincing as Jeremiah was slamming his fists into her back. However, Kara continued to fly through the cloud cover and into the stratosphere as Jeremiah whispered into her ear that he was going to kill her, and then Superman, and then everyone who ever protected her.

Starting with Alex.

"No!" screamed Supergirl as Jeremiah raised his fists into the air while Supergirl continued to rise into the sky. Just after Jeremiah slammed his fists ono her back, Supergirl pushed him off her shoulder.

Supergirl saw Jeremiah falling down back to Earth, roaring at her while reaching out for the blonde woman.

"I'm sorry, dad," Supergirl whispered before she shot down towards Jeremiah at a very high rate of speed, and then gave Jeremiah a devastating punch that he wasn't able to block. The punch increased the rate of his fall back to Earth, even breaking the sound barrier a few seconds before crashing into the ground.

Supergirl landed gently at the edge of the large depression that was formed after he hit the ground hard, and watched Jeremiah's bloody body. His eyes were closed, and his head was facing away from Supergirl while the dust started to settle on his body. Supergirl used her X-ray vision and scanned his body; her face twisted in pain as she realized what she just did after she deactivated that particular power. She fell down onto her knees while she teared up.

More than half of his bones were broken, there was blood all over his body and on the ground, he wasn't breathing, and his heart wasn't beating.

He was dead.

'I killed him,' thought Supergirl to herself as she wiped her eyes and shook her head while thinking to herself, 'you talked to him, Kara. You asked him to stop, he attacked mom, he attacked Alex, he would have killed you. Who knows what would have happened and…. What the..?'

Supergirl stood up slowly in stunned silence as she used her x-ray vision to confirm what she was hearing.

His heart was beating.

His lungs were moving up and down.

She saw that his bones were self-repairing; his bleeding had stopped; his muscles were restitching themselves. And then he moved his fingers.

His entire body was healing. She could see his muscles growing

"By Rao's light," whispered Supergirl as she stepped back with her eyes opened wide in surprise, "what are you?"

Supergirl remembered Lucy telling her that this thing before her was made to kill Kryptonians, but there was nothing about what abilities Jeremiah had. Supergirl could only hope that Lucy didn't know what Jeremiah's powers were going to be; she hoped that the Director of the DEO didn't leave out important information on purpose.

'She wasn't lying,' thought Supergirl to herself when she said she didn't know whatever they made Jeremiah into, existed, 'I listened to her heart beat, she wasn't lying.'

But the fact lay in front of her that a secret organisation created something that could kill her, and her cousin. Then there was the other thing he whispered into her ear before she roughly pushed Jeremiah off her, that he was going to kill everyone that sought to protect her.

'Healing, super-speed, and super-strength,' thought Supergirl to herself as she watched with her eyes wide open in shock as Jeremiah stood up slowly to his feet, and glared at her, 'he can definitely do what he said he would… I… I don't know if he can be stopped.'

And then he roared, while all Supergirl could do was look on horrified, as jagged bones started to protrude from his arms, his wrists, his back, his chest; forming various bone-like plates and jagged blades all around his body.

"Dad," gasped Supergirl as she put her hand to her mouth, and shivered in fear as jagged pieces of bones erupted from the knuckles. The bones stopped growing at anywhere between four to six inches on different parts of his body, and then he roared again before roaring at Supergirl who flew back before Jeremiah sped forward much faster than before, catching her off-guard and then punched across her chest.

Supergirl had her eyes open in shock as she flew up into the sky to not only get her bearings, but to also address the throbbing pain from her chest; the same area where Jeremiah swiped at her. She looked down at the 'S' symbol, the coat-of-arms of the House of El, her family crest, and she was confused.

There was blood on the 'S', her blood. She brought her fingers to her chest, and pushed then through the cut made into the 's' shield, and then winced as she felt the blood from the small gash in her skin. She looked at the blood on her fingers, and then at Jeremiah who was bearing his teeth at the young woman while looking up from the ground, while bone protrusions and plates were forming on his brow.

"Oh no," whispered Supergirl as Jeremiah jumped towards her.

The West Household, ten minutes later.

Barry was oblivious to what was happening out in the dessert near National City as he spent time with Nora in the back yard of the West household. Francine was making dinner with Iris and Wally helping, while at the same time insisting that Nora not help, instead she ordered her friend to spend time with her son. Not one to complain, Nora and Barry were now sitting on the porch stairs that led down to the backyard. Barry had started telling Nora everything she needed to know about his life; while between breaks in Barry's stories, Nora told Barry what happened to her after her Barry and Henry's deaths.

"There's something I wanted to ask you," whispered Nora as Barry nodded his head just as he was about to continue telling her about his experiences with Joe and Iris, "you said that you stayed with Joe and Iris after Henry went to jail, but you didn't mention Francine and Wally. Barry, is there something that you haven't told me?"

"I should have told you this before, I know, mom," whispered Barry as he looked over his shoulder at Francine whose back was to him, and then he caught a glimpse of Iris looking at him while cutting some vegetables before she looked away, giving a smile off on her face. Barry smiled and then turned to Nora before telling her what Joe had told him about his Earth's Francine. Nora listened in surprise about the other Francine's fate, and the fact that Joe didn't even know Wally existed until only a few months ago.

"My God," whispered Nora shaking her head before she looked back at Francine, and then at Barry again, "how is Wally now?"

"He's staying with Joe and me while Iris has her own place," replied Barry, "I'm staying with them since Dad moved out of Central City, and… well, my old apartment.."

It was then that Nora grabbed a hold of Barry's arm, stopping the young man from speaking.

"He did?" asked a surprised Nora while continuing to hold his arm, "why?"

"He was afraid that I'd be targeted through him," said Barry, "or that he'd be in danger and I'd have to choose between saving him or… yeah."

"I'm sorry," said Nora shaking her head before letting go of the arm.

"I understood why he decided to leave," whispered Barry as he nudged Nora's arm, "I still talk to him every day though. I don't know if this changes anything about you…"

"Not having Francine there is a shocker," whispered Nora as she reached for, and held Barry's hand, "but having you and Henry there? How can I say no?"

Barry just smiled at Nora when Wally opened the door and popped his head out the door. Barry and Nora looked back at the young man who said that there were two people looking for him, for Barry Allen. Nora and Barry looked at each other confused; with Bora believing that the only person who knew about him was Supergirl. The two of then then got off the stairs, and then followed Wally into the house, where Francine and Iris were standing at the door looking back at him. Barry stood next to his mother while holding onto her arm, as the both of them looked at the blonde woman and the dark-haired African American man. Barry noticed that the woman was looking around, and then over her shoulder, before looking back into the house; while the man was looking at him, and then leaning forward to look inside the house, before leaning back and then looking at him again.

"I'm Barry Allen," Barry said with a nod of his head.

"My name is Alex Danvers, and this is Hank Henshaw" said the blonde as she motioned to herself, and then to the man next to her. Barry reacted by widening his eyes in surprise at hearing the name of Kara's sister. He had a chill go up his spine when he realized that Kara wasn't with her while another part of him was asking how she knew about him. All those questions led to the same conclusion, that Kara was in trouble, "we're with the FBI and…"

"Can we see a badge?" asked Iris who looked back at Alex and Hank with her arms folded over her chest, "how did you..?"

"Please," pleaded Alex as she looked at Barry, "she's in trouble."

"Who?" asked Francine.

"Mr. Allen," said Hank as he put his hand on Alex's shoulder and gently squeezed, "we don't have time."

"Mom," said Barry turning to look at Nora and then he held both of her hands, "I have to go.."

"No," Nora said shaking her head, "I…."

"Supergirl's in trouble," whispered Barry as Nora teared up, "mom, this is what I do. I'll be alright, we'll be alright, I swear. I made a promise to you that I'll come back, and I swear I'll come back."

"If this.. whatever it is can cause Supergirl problems," said Wally, "then how can… I mean it's Supergirl and…"

"And.. and..," Nora said as she looked at Barry's eyes, "and my son's the Flash."

Barry nodded his head as Alex and Hank looked on in shock as Barry became a blur while he ran to the backpack in the living room, and then ran back to the woman he called his mother, dressed head to toe in red.

"That's new," whispered Alex.

"It is," replied Hank.

"I'm coming back, mom," said Barry as he kissed Nora's cheek, "I swear I'm coming back."

Nora nodded her head as she tried to push back the sob that was stuck in her throat as she thought about what Barry might be up against. She knew, everyone in the house knew, that if it was something that Supergirl had a problem with, then it wasn't any good.

It was downright dangerous.

And her son was heading into the unknown.

But she looked into Barry's eyes and just knew that this son from another Earth would be okay, he had to be okay.

"Run, Barry," whispered Nora caressing his cheeks. Barry then took a step back, nodded his head, and then turned while running.

Everything went in slow motion as he ran, yellow electricity behind him and crackling around his body, while on the way out he held on to both Hank and Alex. Once he hands his arms around their backs, the two of them were to see themselves moving so fast that everything seemed to slow down.

"Which way?" asked Barry as he ran.

In the meantime, Nora watched her son disappear down the street while Francine held on to her shoulder. Nora heard Iris and Wally turn on the television, and switch to the news. All there was, as Iris and Wally sat down, was the picture of the destroyed Danvers house, and then a breaking news ticker as the image of the destroyed home was replaced by a camera phone video of something crashing into a pavement in the outskirts of National City. The four of them then watched a creature covered in a dirty white coloured armour, which consisted of various plates and jagged spikes, crash down right next to the object that had just crashed into the ground.

The four of them watched the image on TV that was taken on a shaking camera phone as people ran away screaming, while Nora sat down next to Iris who was covering her mouth with her hands. The female voice-over was saying that this video was being live-streamed to Catco, and then they heard a wild scream form the location of the creature as blue light erupted from the depression formed by the object that hit the pavement earlier, and hit the creature in its chest.

The creature, however, just struggled off the heat vision.

Nora and the others looked on as a blue and red blur shot out of the depression and rammed into the creature flinging it back out away from the city. However, the next thing they knew, the creature jumped back into frame and hit Supergirl, slamming her down into the pavement again.

"Oh God," said Nora as the four of them, together with the entirety of Central and National City, saw the creature continue to pound Supergirl into the ground, while releasing a loud roar. There was a lull when the creature stopped for a few seconds as Supergirl remained unmoving, but it started to pound Supergirl again when her arm seemed to move. However, Nora and the others saw Supergirl give as well as she took when she used her super-breath and pushed him away. As she was getting up, then saw her hunched over and bleeding before she flew into the creature, grabbed him and then turned mid-air, before slammed him into the ground.

Wally got up and punched the air when Supergirl shot back into the depression created after slamming the creature into the ground. He, and everyone else watched, as Supergirl threw a flurry of punches that cracked parts of the pavement, and the streets, open while she screamed in rage.

"Come on!" shouted Wally in excitement as Supergirl continued to pound the creature further into the ground when she was suddenly kicked away, and then a blur escaped from the depression. The camera shook as the person holding it ran while the two juggernauts continued to fight in the distance. The video, now with a police officer telling everyone to back away, then showed Supergirl spinning in the air while holding onto the creature as people screamed and started to run away from the fight.

Iris Wally cheered when they saw Supergirl fling the creature into a branch of the National City Bank. In the meantime, Francine just looked at her worried friend, and then back at the TV hoping that Barry knew what he was getting himself into.

DEO Headquarters, a few seconds ago.

Lucy was preparing to head out with a team to National City, which was where the fight was taking place now. Their assets were already ready to be sent to the dessert when the direction of the fight changed and the creature that looked like Jeremiah, started to push Supergirl towards National City.

No matter how much Supergirl was trying to push the fight away from National City, Jeremiah pushed back harder until National City, at least the outskirts, was the battleground. Lucy diverted as much of her forces as possible with whatever handheld advanced weaponry they had on hand to National City.

She was looking at the unconscious Eliza when she felt a gust of wind from behind, followed by sounds of the agents around her raising their weapons at something. Lucy turned around to find a man dressed in a red suit, and on either side of him were Alex and Hank.

"Director Lane," smiled Hank as he put his hands up, as did Flash and Alex. He nodded towards Barry, before telling Lucy that he was a friend.. he was here to help Supergirl.

"I'm the Flash," said Barry putting his hands down, "and I'm here to help. I don't think we have time for the regular superhero and the third party para-military outfit not trusting each other stuff… so could we skip all that? Supergirl's in danger, and I need to know where she is… please."

"It's life or death, Director," said Hank, "Supergirl trusts this man."

"She told me a few friends were coming by," said Lucy before telling everyone to put their weapons down, and head to the vehicles. She then turned to the agents manning the screens and told them to show the newcomers where Supergirl was at that moment in time.

"National City Bank, ma'am," replied the Agent as Barry's eyes opened wide.

"Dear God," whispered Barry before he turned to Lucy and asked her how to get to that location.

"I can show you," said Hank, just before Lucy could answer, as he took on his Martian form, much to the shock of Barry who stepped back, "do not be afraid, my real name is J'onn J'onzz and I am from…"

"Please don't tell me Mars," whispered Barry.

"Indeed," replied J'onn.

"I have so many questions," whispered Barry, "but first…"

"Listen to me!" said Lucy when Barry was about to move, "this thing… whatever it is? Is not Jeremiah Danvers. It can't be.. look, what I've been told is this creature was made to destroy Supergirl and Superman."

"What?" asked an outraged Alex while J'onn just shook his head. He then told Alex that he wasn't aware of what was really going on at CADMUS, that their projects were above his own clearance level.

"I get that this thing is super-strong, but If we don't go now?" said Barry, "Supergirl's going to kill that thing, but she'll die too… I'm heading out there and…"

"She'll die?" asked a stunned Alex, while an equally stunned Lucy stared at Flash.

"No time," said Flash, "see you in the city."

Alex and Lucy saw Barry grab J'onn, and then vanish in a red and green blur, with a trail of yellow lightning before looking at each other with worry etched onto their faces.

"Grab your gear, Agent," said Lucy as Alex nodded her head, "I want you leading a team out there, we're going to help as much as we can to help Supergirl, and I want a team getting as many civilians out of the way as possible."

"Understood," said Alex nodding her head. She took a look at her unconscious mother who was in the clear walled infirmary, before head towards the armoury.

She was going to make sure her sister didn't die today.

TBC.
