"Alright, how do I do this?" Barry asked a monitor showing Eobard Thawne in his cage down in the pipeline, after coming to the decision that would do it. He was going to save his mother.

"Simple really. We use the particle accelerator." Thawne answered.

"How do we do that?" Joe asked. The rest of Team Flash in the Cortex as well, wanting to make sure that nothing went wrong. They could never be too sure when dealing with someone who built their own cage. "The last time that thing went on, a lot of people got hurt."

"Yes, well this time the accelerator will do what it was originally intended for. Before we injected two hydrogen particles that collided with each other at high speeds. This time, we're only going to inject one," Thawne told them.

"And I'm what it will collide with," Barry realized now why Thawne needed to get him faster.

"Exactly," Thawne smiled at him. It was sickening. "The impact will create a tear in space and time, allowing someone the ability to travel from this time to anytime. For instance, my time. Or say, the night your mother died,"

"If I'm going to do this, how fast would I need to be travelling?" Barry asked.

"By my calculations, around mach 2," Thawne answered.

Barry scoffed at that though. "I've never gone that fast," Barry pointed out.

"You will. I believe in you Barry," Thawne encouraged him.

Everyone just glared at him when he said that. They knew he was only saying that for his own personal gain, but after working with each other for a year, Thawne obviously knew exactly what to say to get the desired reaction.

"Not that I care but how will you get home? You constantly lose your speed at the most convenient time, don't you?" Barry smirked, glad that he had something on the yellow clad speedster.

"That's why you're going to build me something that will allow me to travel through the wormhole without any ill effects." Thawne said.

"You need us to build you a time machine?" Barry asked to clarify what he was asking of them.

"I've already gathered everything you will need. You simply need to construct it,"

Barry shook his head in disbelief. Thawne had really prepared for this moment, making sure everything was just as he wanted. Barry turned off the monitor before turning back to face his team.

"So, what do we think?" he asked.

"I just have one question," Cisco raised his hand. "Why? Why would you ever consider this?"

"You know why," Barry simply said.

"You have been presented with a rare opportunity Mr. Allen. The chance to go back and right a wrong, but there can be many consequences that you must be made aware of," Prof. Stein added in his own opinion.

"I understand what would happen if I were to save my mother. History would be changed. Everything could turn out completely different from what I know," Barry said.

"Exactly. Every decision creates a chain reaction. Moments upon moments each impacting the next. If you were to go back and save your mother, that event would alter everything. Nothing you know would be how it is, and you would never know the difference because you wouldn't remember," Stein agreed.

"I'm going to do this. I have to," Barry said solemnly.

"Well then according to these notes from our time traveler, you would have approximately a minute and forty-seven seconds to alter the course of history before the wormhole you created would become unstable," Stein said, looking over the notes provided by Eobard.

"Do you think you can even do this?" Iris questioned him. "I mean you said you've never gone fast enough to reach the required speed,"

"Let me worry about how fast I need to go, in the meantime we need to build the time machine Thawne mentioned," Barry dismissed her concerns.

"I can help with that," Ronnie offered his services.

With no more room for discussion, Barry, Cisco, and Ronnie parted to gather the plans and materials in order to build the time machine.

Once all the preparations were complete, Barry stood outside the entrance to the pipeline, where he would be attempting to travel through time and save his mother from death.

Goodbyes were said with the insistence that no matter what timeline, they would always meet and become friends, no matter the circumstances.

"So, this is goodbye?" Caitlin asked.

"For you maybe," Barry said casually. "I'm probably going to be seeing a brand new version of you as soon as I get back,"

"Well if this is goodbye, there's some things I want to say," Caitlin told him. "I hated you when we first met. In fact I still don't like you to this day, but through it all I know you'll come through for me just like I'll always come through for you, so thank you,"

"Ehhh," Barry shrugged it off, acting as if he was contemplating whether he would actually do anything for her.

Caitlin just punched him in the shoulder in retaliation. "Jerk,"

Barry chuckled slightly at that. "I'm glad to have known you Ms. Frosty,"

"Ditto Fleet Feet. Don't let the new me disturb you too much. That's your future wife you're talking to," Caitlin teased him.

"I'm sure I'll love her no matter what," Barry smiled as he put on his cowl.

The goodbyes were over and he ran into the accelerator, waiting for the door to close behind him.

"Well," Thawne said from his cage above. "This is the moment we've all been waiting for. Run Barry. Run,"

With a determined look, Barry took off, running as fast as he could. He let all of his feelings go as he focused completely on running. To him, nothing else mattered in the moment. Everything he'd learned, all the effort put into increasing his speed for the past year, it all left him as he felt the pull of the Speed Force guiding him to go faster.

In the Cortex, the rest of the team was monitoring the screens to make sure everything was running smoothly.

Barry's speed was gradually increasing, the structural integrity of the accelerator was holding, despite the insane speed, and therefore friction, Barry was generating from running around in a circle.

A small rumble shook the building, which alarmed several of the inhabitants that something may have gone wrong.

"What's going on?" Joe asked. "Is Barry okay?"

Cisco took a look at a screen to see what may have caused the shake. "Yeah, he just passed mach 2," Cisco said in disbelief.

It was incredible. It didn't seem possible that Barry had already surpassed his previous records and he hadn't even been running for a full minute. And according to the speedometer, his speed was still increasing.

Barry's view of the accelerator shifted as soon as he passed the mark. His surroundings faded away as they turned into a blue tunnel with various images. Some he recognized, others he didn't. Like what was with that giant boot crashing from the ceiling?

Noticing Barry's attention straying away from the present, Eobard realized what was happening. "What you're seeing Barry is the Speed Force. Your past, present, and future all at once. So you need to focus on where you want to go. Think about your mother Barry. Think about that night,"

Barry tried to focus on the pivotal point of his entire life. The night his mother was killed, father was sentenced to prison, and he was shipped to the foster care system, but just moments before all that. As an image of Caitlin with stark white hair shooting icicles at a giant metal man faded away, he saw what he wanted.

His memories of that night never left him. He'd just come down from the stairs to see his mother in a tornado of red and yellow lightning. He needed to go there. Soon the images seemed to go on repeat as he witnessed the events happen again and again.

Prof. Stein reached for his cup of coffee, only to notice the fluids floating in the air, indicating it was time. "Inject the hydrogen particle now," he instructed.

Caitlin pressed a few buttons, and then a new image appeared alongside Barry in the opposite direction. The two travelled beside each other for a few moments before they crashed into each other and they both disappeared.

"Barry, he's gone," Caitlin said in a soft voice.

"A wormhole, and it's stable," Stein immediately noticed. "Start the countdown," There wasn't a second they could waste. Any moment they delayed meant risking a black hole that would destroy the Earth.

Meanwhile, Barry just arrived at his old house. He was in an empty room when he heard the familiar sounds of the two speedsters running and the sound of his mother crying out in fear.

Barry silently crept down the stairs to avoid detection from his other selves. If either one of them caught sight of him, who knew what repercussions that would have on the timeline.

Barry hid behind one of the doors and gently opened it to view what was happening to know when he would be able to get in and save his mother.

But at that moment, everything seemed to go still. His future self had knocked The Reverse Flash away for a brief second and looked his way as if he knew he was already there. His future version raised his hand and shook his head. The gesture was clear on what he meant. 'Don't interfere. You're not supposed to be here. Let things progress how they are supposed to,'

The interaction was only for a few brief seconds, even less in actual time, but so much was said between the two that no words were needed.

The Flash ran off just as he remembered and grabbed his younger self out of the house and rendered his father unconscious, leaving The Reverse Flash alone with his mother.

It didn't take long for the yellow clad speedster to grab a knife from the kitchen and stalk towards his mother.

With tears in his eyes, Barry came to a can't be stuck in the past. There's no going back, you just need to look towards a brighter future.

Still, it took all his willpower for him to not break down the door and tackle The Reverse Flash away from his mother, and he flinched when he heard the distinctive sound of the knife piercing into his mother's flesh.

When he heard the telltale sound of a speedster running, Barry knew it was clear to step out into the open. There was still one thing left to do. He needed closure.

Walking out, he noticed his father was still unconscious. He wished he could take him away, making it so he wouldn't be suspected of the murder, but he'd already promised himself that he wouldn't interfere more than he already had.

Going to where his mother was, he saw she was still alive, even if it was only for a few more moments. It was still long enough for him to do what he had to.

Bending down, he grabbed her shoulder as she was panting in desperation and fear as the life in her body slowly escaped its vessel. "Hey, hey. It's okay, you're going to be okay," he whispered. He didn't trust his voice enough to not break apart at seeing his mother like this.

"My husband, my son, are they…?" she gasped out. It warmed his heart that in her last moments of life, all she cared about were the people around her and not herself. He wished he got to know her more, before she was ripped from him.

"They're okay. They're both safe, I promise," he reassured her. His voice was cracking and tears were beginning to drip from his eyeholes. He didn't know how much more time he still had, but that didn't matter. He just needed to say all this to her before it was too late.

"Who are you?" she asked.

"I'm…" Barry bowed his head. He was contemplating whether to tell his mother all this. About time travel and this world of the supernatural. "I'm The Flash," he decided.

"I don't understand," Nora shook her head in dismay. Confusion and fear in her eyes as she gazed at the unknown thing hovering over her.

Making a decision, Barry leans back, beginning to take off his cowl to reveal his face to his mother. He let out a gasp as he did. He couldn't believe he was actually doing this. She probably wouldn't recognize him, but he still wanted her to know it was him, even if she would probably write this off as nothing but the hallucinations of a dying woman.

Taking a good look at the unmasked man, her eyes ran over his features. "You look just like my father," she commented on the similar facial features the man bore with her family.

Barry lets out a small laugh without any humour. "This won't make any sense, but it's me mom," Barry told her. "It's Barry,"

"Barry?" Nora looked up at the man with hope and happiness in her eyes. She couldn't believe that this man was her son. He was so beautiful.

"Your Barry," he confirmed.

"Oh, my beautiful boy," Nora cooed as she managed to raise a hand to grace his cheek as she took in who her son would become. He was everything she could hope he would be.

"I got a second chance to come back here and…" Barry took a shaking breath. This was all too much for him. He wanted to save her, he wanted to run to the hospital and pray that there was still time to save her, but he remembered his father's words, that she wouldn't want that, if it meant he wouldn't be able to live up to his potential.

"To tell you that I'm okay," he said what he always wanted to tell her. If he couldn't save her, he was going to let her know everything he ever wanted her to know. What she meant to both him and his dad.

"Dad and I are both okay," he continues to say. She just nodded along with him, taking his word for it. This was her son, she would trust him with all her heart that everything would turn out okay. "And we love you mom. I love you,"

Barry takes heavy breaths to settle his weeping. He wouldn't let his emotions take away time from his mother, to be able to finally say goodbye after all this time. There was time to sob later, right now this moment was all about her.

"Goodbye Barry," she whispers. Her arms failing her as their strength begins to fade away, her fingers becoming cold to the touch. "Goodbye," she mumbles her final farewell as her body goes limp, the light fading from her eyes as she dies right there.

"Mom?" Barry tentatively asks. He didn't want to believe their time had expired. How do you say goodbye to the mother you always wanted to meet? "Mom?" he shook her shoulders.

He was soon forced to the conclusion that she was already dead. His resolve faded away as he began to sob on his dead mother's body. It wasn't fair. Just a few moments ago she was well. She wasn't supposed to become a casualty in his rivalry with The Reverse Flash. She was never supposed to have gotten involved. But it was all because of him that she was gone. It was all his fault.

He didn't dare touch her face. In addition to the fact that he couldn't leave any evidence that he was here, he didn't want to interrupt the beauty of his mother right now. She looked so peaceful, and ignoring the bloody wound in her chest, she looked like an angel to him. He couldn't risk ruining this image of her for him.

He didn't know how long he would have stayed there, weeping over the death of his mother again, this time actually witnessing the deed. He could have spent an eternity there and it still wouldn't have been enough time, but he had to leave. The wormhole would be closing soon, and without it, he didn't know how else he would return back home to where he actually belonged.

"I guess this is it, huh? It's been a pleasure working with you both." Thawne said to Cisco and Caitlin while standing near his time capsule.

"Don't ever come back." Cisco said with such distaste.

"I never told you this Cisco but in a way, you have shown me what it's like to have a son."

"You did say that to me, in a timeline Barry erased. That was right before you killed me," Cisco glared at him.

"Well I can't say I'm sorry about that. I probably had my reasons," Thawne shook off his hate.

"Get out of here already," Caitlin demanded.

Thawne raised his hands in a placating fashion before he stepped up to the machine and turned it on. It began to float and head towards the wormhole before them. "Home," he whispered to himself with a longing tone in his voice.

But there was a subtle irregularity with it. It was moving in a strange fashion that wasn't natural. It was almost as if something was…

Barry shot out of the wormhole and collided with the time capsule, shattering it to pieces.

Caitlin and Cisco scrambled out of there the moment they saw something was going on. Caitlin didn't realize it, but she had the hints of a smile on her face once she saw the irregularity was Barry. That meant he didn't save his mother. That he decided to stay with her-THEM! She meant 'them'.

Groaning at the pain, the two speedsters slowly raised to their feet, staring at each other. One in hatred, the other in disgust. "You didn't save her?" Thawne asked. "Why? You could've had everything you ever wanted!"

"I already do," Barry simply said.

Glaring at him, Thawne put on his cowl and immediately began to vibrate his entire body, his eyes glowing red from the lightning behind them. "Not for long,"

Eying the other for a moment longer, the two sprung into action, not taking any notice of the wormhole behind them that, if left alone, would cause the end of the world and beyond.

The two ran around the accelerator, each trying to gain the upper hand. Unfortunately, experience won out in the end as Thawne managed to get Barry in a chokehold, pinned to the wall.

"Just so we're clear. After I kill you, I'm going to kill them," Thawne gestured in the direction of the Cortex, indicating the rest of the team. "And then I'm going to kill your father. I always win Flash!" Thawne raised his right hand, all set to vibrate into his chest and rip out his heart.

The sound of a gunshot rang throughout the large room as it was revealed the owner of the gun, was also the victim. Eddie had shot himself in the chest.

Everyone was in shock as nobody knew what was going on through his head to commit suicide. Iris screamed out his name and Joe ran down to assess his partner. "Eddie! What did you do? What did you do?!"

"No such thing as a coincidence," Eddie mumbled to him with a smile on his face.

"What's happening?" Barry asked in confusion. As Eddie slipped further into death's grasp, The Reverse Flash was vibrating erratically, as if he had no control of himself anymore. Barry had no idea what was going on.

"Cisco, help me," The Reverse Flash gasped out. Nothing seemed wrong with him, but something was obviously wrong if he was begging for help.

Cisco soon came to the realization of what was going on. "Eddie is his ancestor. If Eddie dies, he'll never be born and…" Cisco took a look at the man, only to see a shock. The Reverse Flash was no longer vibrating and his face could be clearly seen. Only it wasn't the face they had come to recognize. It was entirely different. His disguise was fading away as he was becoming non-existent. "He's being erased from existence."

Iris was quick to arrive as she cradled the man she loves in her arms, pleading with him that he wouldn't leave her.

"Eddie! Stay with me, okay? Please, stay with me. I love you!" Iris said while holding the love of her life as he slowly died in her arms.

"He was wrong, it turns out," Eddie mumbled. "I'm a hero after all,"

"You are Eddie. You are my hero," Iris sobbed as her fiance was dying in her arms.

"That's all I wanted to be. Your hero," Eddies whispered before he choked on his blood. It was soon followed by his death as his blank stare would forever be left gazing at nothing.

With Eddie now officially dead, the timeline soon caught up to the present. Glowing cracks could be seen appearing on Eobard's body as he was slowly being erased from existence.

With nothing left to lose, Eobard turned to face Barry one last time, just to taunt him. "I've controlled your life for so long Barry. How will you get along without me?"

With that, Eobard's body completely dissipated, no evidence left that he was even there as the timeline fixed itself to make it so he was never born.

Through it all, nobody noticed the wormhole slowly gaining in size, but with the shift in the time stream due to the elimination of an entire family line that was supposed to go on to do great things, it became too much for the tear in time and space to handle.

The wormhole was ripping apart everything in its path. It was no longer stable enough to remain in the building. It would eat away the entire planet and whatever else it could find afterward.

Everyone who was in the accelerator was quick to notice the growing danger. They just couldn't catch a break today. But then again, they brought this upon themselves. They did this knowing the risks, and now they were paying for it.

Iris didn't want to leave Eddie behind. Even though he was dead, she refused to leave his body for the wormhole to take.

Joe was forced to pry her away from the corpse as the pull of the wormhole grew so much, it carried the dead body into its centre, reducing it to ash.

Everyone ran outside as the wormhole's instability caused it to become a singularity, escaping from STAR Labs and forming over the entire city. It would destroy everything.

"So that's what we didn't want to happen," Cisco commented on the gigantic mistake.

"The singularity won't stop, even after the Earth is gone," Prof. Stein informed them of the power of the singularity.

"How do we stop it?" Caitlin prayed for an answer. If they didn't manage to close it, life as everyone knew it would be gone.

"I'm afraid the accretion disk has already assembled." Stein said with regret.

"What?" Joe turned to him, not understanding a word he just said.

"Diffused material that's in orbital motion around the singularity." Stein tried to explain what was going on, maybe provide someone with an idea of what to do.

"What does that mean?" Caitlin asked, still not understanding how any of this was helping.

"We have to disrupt the motion," Barry came up with a plan. "Basically it's just like the tornado only upside down, and bigger, and scarier." Barry referenced the first thing he ever did as The Flash.

"Barry, that event has an energy level of at least 6.7 teraelectron-volts. It cannot be stopped!" Stein warned him from doing anything drastic.

"I have to try," Barry shook his head. He had to try everything he could to stop it. If he didn't he was already dead along with everything in the world.

Placing his cowl back on, ignoring the irritation it caused with all his wounds, Barry looked to his team for what may be the final time.

His gaze lingered on Caitlin for just a moment longer. He tried to express how much he actually cared for her and how sorry he was about everything between them.

Turning around he looked up at the black hole that was tearing apart his city. Preparing himself for the run of his life, he felt the sparks behind his eyes, the lightning coursing through his veins. This was all or nothing.

Shooting forward, he headed towards the tallest building in the city, trying to get as close to the singularity as he could before he would be forced to rely on what was in the air.

All around the city, everyone looked towards the streak of lightning heading straight to the singularity. Their last hope of survival. The majority of them hoped he could actually do something against this event.

A small minority though were filled with dread of what he would have to do if he were to have a chance to even stop it.

Caitlin looked up to see the lightning bolt running up the side of the building that was closest to the black hole. Worry filled her entire being. Tears were in her eyes. At that moment, she didn't care about the rest of them. Her sole focus was on the man, who she had despised for over a year and had become one of her closest companions, risking his life. She just wished she didn't spend so much time hating him for nothing but a simple misunderstanding between them. But all else, she wished he was here so she could actually say it to him and not about to jump into a black hole.

Barry had to stay focused. He couldn't afford any mistakes. He was running along the side of a building, avoiding any debris that was making its way into the giant hole in the sky.

Once he reached the end of the building, it was that debris he relied upon now to bring him closer. He couldn't stop. He had to keep his momentum going. He jumped from one rubble to the next, not stopping for a moment.

He'd reached the outer shell of the singularity, but if he was going to have any chance to stop it, he needed to get deeper. He needed to go into the belly of the beast.

With that, he jumped into the hole with the hope of the entire world resting on his shoulders.

That's all folks. Season one is officially over and I hope you all enjoyed. I'm going to be taking a break this week so unfortunately I won't be uploading next week. Possibly the week after but we'll see how long this little hiatus of mine will last. Don't worry, I fully intend to see this through and will return for season two in the following weeks.

Until then, post a comment on your thoughts. Anything specific you'd like to see in the next season. Maybe any questions about my writing process, I'm all ears and I will respond to you as quickly as possible. See you all in the future.
