Author's Note: Awww, can't believe we're almost done this story! Four more to go! After this, I'm planning to make another Flash story. I still need to outline the story of what's going to happen and such so yeah. It will most likely come out in September; I'm only estimating simply because I want to finish the other stories that are out so yeah…Let's get going!

Summary: After Barry brings back his grandson to the light, Inertia gets out and greets them, telling them of his plan that has already been set.

Chapter 14: The Plan is Set

Barry stared at the figure with wide eyes, his throat going dry at what he was seeing. He couldn't believe it. That monster…that monster had turned his own grandson against him.

"Bart…"

"Bart?" the evil chuckle escaped his lips, sending shivers down his spine.

This wasn't like him at all.

"Bart, don't do this."

"Oh but what if I want to? Hmm…what will you do now?" the evil speedster sneered, his grin is nothing but nasty.

Barry stood stiff in his spot and he was able to make out the changes that were on his suit. Instead of the yellow which he was accustomed to see, the yellow had a darker shade and instead of the red, it was replaced by black.

Noticing his silence, Bart smirked. "Oh, admiring my new look? You see, I prefer this look rather than my old one. The old one was…tacky. Out of date." he sneered. "Oh, don't cry now. I mean when we're finished, you'll be only begging for mercy. Better save your energy." he drawled, taunting him.

Barry regained his composure, hands curled into fists and he glared at the dark side that dared took over his grandson. He was going to bring him back and if he has to fight him to knock some sense into him, then so be it. He was going to force himself even though this tore him apart.

"So…" Bart replied, cockily cracking his shoulders as he extended his arms out as though to invite him. "Make your move."

Barry tightened his fists, eyes narrowed as he set his stare on his grandson. Apparently, "Bart" found this amusing since he cocked his head to the side.

"What's the matter?" he smirked before pausing. "Oh wait; it's simply because you can't fight your dearly loved grandson, can you?" he jeered. "Well then. If you won't make a move, then I will."

And just like that, the evil speedster performed his attack by creating a lightning bolt that was two times the power than when Barry creates it. The black lightning raced towards Barry who started zooming out of the way but it was futile. The power struck the Flash painfully and he was sent flying backwards, tumbling to the ground in a painful blow.

"Woah what is going on there? You just go struck by a power that's doubled by yours." came Cisco's voice.

"Right now, I'm a little bit busy."

"But your—"

"Not now, Caitlin."

"You know, the only way to hit a fast moving object is to hit it with enough power of your own."

Barry's throat went dry and there was a huge hesitation from when Cisco said that. He really didn't want to hurt him. Not at all. Barry tightened his fists at what Inertia had done to Bart.

If he sees him, Barry will make sure he will pay.

"Barry…"

"I—I'm sorry. I can't. I just can't. It's Bart. That was Bart—Inertia transformed him to the dark side. I can't hurt him." his voice broke.

There was a terrible silence that had befallen and it unnerved them. What broke Barry the most was what Cisco just said.

"I'm sorry but…you have to. Or otherwise, you will be destroyed."

"What's the matter, Flash? Can't handle the fact that your grandson is dark? Evil?" Bart sneered. "You're pathetic and weak. You're not a hero, Flash."

"I am." he snarled.

"Really? Then a hero would save their friends no matter what the circumstances are." Bart gleamed with madness. "So, if you want your beloved grandson back then you have no choice but to kill me." he smirked.

"I am not going to kill you. I am going to save you." with that, Barry began running but that only infuriated Bart more.

"You can't save me!" he screeched, throwing bolts of lightning at him. "It's far too late! Face it, Flash. This time, you're late. You were late to save your grandson!" he snarled.

However, Barry didn't listen to the evil side of Bart. He simply tried to ignore his cursed words; they were taunting him and he hated it. Barry didn't want to admit it but in some ways…the evil Bart was right. He came here, too late save him. It was too late to save Bart.

Of course, he wouldn't be too late if he hadn't had any obstacles in the way. For instance, Rose. She was the one who made him late. He felt his blood boiled in his veins but because he was so deep in thought, he didn't notice the attack that was literally shot right in front of him. Right in front of his feet and this forced him to fly off-course and fell on the ground with a hard thud.

A thud which knocked the air out of him.

He gasped at the lack of air, coughing before he was able to breathe properly. So, maybe being deep in thought wasn't such a great idea. Especially when you're fighting a twisted grandson.

Fantastic.

"You can't run forever, Flash! Soon enough, you're going have to strike me." Bart sneered.

Barry quickly up, eyes set on his face and he walked towards him.

"No, you're right. But if there's a chance to bring back what once was yours then I'll do it."

Bart widened his eyes. "You're willing to risk your grandson's life? Even if it means that it will probably kill him?" he replied, eyes wide with shock.

"I'll take my chances." Barry replied, bitterly.

And with enough charged power, the Flash released his attack and the streak of red painfully zapped the evil Bart which caused him scream in agony. The zaps resumed electrifying him in the most gruesome way as possible and it was harder for Barry to watch so he looked away, staring at the floor.

Bart resumed screaming as the electricity went in is body. His black eyes were now changed to his normal eyes and as soon as it started, it stopped and Impulse fell down to the ground with a thud.

Barry's heart skipped a beat and for a moment, it felt that his heart had actually stopped beating. Shaky breaths were drawn from him and he dared to look at the fallen figure.

"Bart?" Barry's raspy voice came.

He pushed himself up but he felt like vomiting, his heart aching hoping for him to be alright.

Within a heartbeat, Barry reached him, falling to his knees and didn't breathe a word. He felt his muscles tightened, shaky hands reached out for the fallen speedster and Barry touched his neck and waited.

Waited for a pulse.

After a few minutes, Barry started to think the worse and that crashed on him; he couldn't bear to lose another family.

"Bart…" he begged.

And then, a second later, a gasping sound came followed by coughing. Barry widened his eyes at the waking figure and he let out a long relieved sigh.

"Ungh…what…what happened?" Bart muttered, placing his hand on his forehead.

"Bart, you're alright!" Barry cried out, hugging his grandson.

Bart hissed from the tight grip that came from his grandfather. "I kind of need to breath, you know." he squeaked.

"Sorry." the Flash replied, sheepishly.

The two shared a silent moment, staring at each other's eyes as though to study what they were thinking or feeling. Bart's eyes gazed down to a scratch that was on Barry's arm and sadness immediately fell over.

"You're hurt." Impulse responded, bitterly.

Barry covered the scratch that had dry blood and he dismissed it. "Don't worry about it. You're safe and alive and that's all that matters."

"But I'm the one who hurt you." Bart replied, glaring at the ground as though it was its own fault for everything that happened.

"You will be the one who's going to hurt him." he said, darkly.

Bart stared at the ground with a hard look, his fists clenched with anger. He was disappointed in himself. Upset with himself. Angered at himself. He could've prevented from being "transformed" but he didn't. He just sat there and did nothing. Did nothing to prevent from being injected with that forsaken substance.

He was angry and he didn't do anything about it.

Sensing he was at a war with himself, Barry gave a short sigh. "Bart…"

"No. Don't." he replied, sourly shaking his hand off. It would be an understatement if Barry hadn't felt hurt when Bart shook him off. "I could've done something and yet, I just stood there and didn't do anything. I could've killed you." he whispered, his eyes starting to pool with hot threatening tears.

"Impulse, everything is okay. I'm the one that should be blaming myself. I left you alone in the house—I know you wanted to." Barry quickly said as he saw Bart opening his mouth to argue. "I should've dragged you, nonetheless. But instead, I got you kidnapped by the speedster and had him access to you. I'm sorry for putting you in danger even though it was not meant to be."

"But I'm the one who allowed to let Inertia to do what he wanted to. I could've fought him off but I didn't." Bart replied, staring sadly. "I'm so sorry." he responded, burying his face in his hands.

"It's alright." Barry murmured, bringing the young kid into his arms. "Don't ever blame yourself. Okay?" he whispered.

The short sweet moment got interrupted by a sneering voice that came from the darkness.

"Aww, isn't this sweet? The papa giving a hug to his cub." he sneered. "How…cute."

The voice tore them apart and both of them glared at the intruder. Inertia cackled, sneering at the two.

"It's cute enough to make me vomit." he drawled.

Growling, Bart got up, fists clenched from anger. "Inertia, you've gone too far. No you're gonna pay."

"Am I?" Inertia taunted. "How can a speedster like you make a bad guy like me pay when you don't even have the guts to kill a being?" he maliciously replied.

Inertia began to laugh as he saw Impulse's guard being lowered down, the speedster's eyes widen as Bart started to realize…they really don't chance against him.

He was right after all.

How can they defeat Inertia if they can't take a life away even if that being is cruel and wicked?

"Impulse…it'll be okay. We will find away on how to stop this madman from killing. Killing is not always the answer." Barry replied.

"But…But…I…"

Barry went in front of him and placed both hands on his grandson's shoulders. "There are some things that you can't fight, Impulse. Some things, you just have to live with." Barry responded. "And we're gonna do this the right way, okay?"

Bart stared at his grandfather, eyes wide and he let out a breath he didn't even knew he was holding. Frozen in spot, Bart merely nodded.

Just then, there was a loud explosion that came from the building and it made them look (Barry had to turn around since his back was facing the warehouse). There, above the roof, was a tall column of blue and white with crackling energy.

Upon seeing this, Inertia cackled something awful.

"It's too late to make up a plan, Flashes. You see, while you two were busy fighting, I made my plan be in set." he grinned, malevolently. "There is nothing you can do. It's over! Darkness will come at last!" he laughed cruelly as his plan was set to motion.

Both of the speedsters stared at the column of energy that began to pick up and soon enough, strong winds started to form. However, both of their faces set a determined look and as they stared at the column, both of their eyes showed streaks of speed…

Author's Note: Wow, I'm actually pretty proud of this one. So yeah, we're not too far from completing this story—only four more to go! I can't believe it! After this, I will most likely get another Flash story out only I don't know when it will come out since it is still in the planning. So yeah…what happens next? Find out!
