Alright, here we go. This chapter is gonna be important for the series, and hopefully one you guys will like. Let's get to it.

Chapter 9- Secrets of Speed

Nora sighs as she goes over security footage of the robbery at the Kord Industries warehouse in Star City commited by Grant and Evelyn. It's been two days since Jenna and Zoe left Central City to go track down this mysterious Diana. There's been no sign of Godspeed or the Rogues since her fight with Godspeed. William has been hard at work trying to find Godspeed's lair, and has been making progress, but is still not close.

"Hey, sis." Nora turns around to see Stephen walking towards her.

"What is it?" she asks.

"I've been thinking. Even if Jenna and Zoe come back with Diana, we're still outgunned. Yes, with Diana's help, we might be able to defeat Deathstroke, Boomerang, and Weather Witch. But I doubt that even this Diana can help us against Godspeed. Ultimately it's going to be down to just the two of us to beat him. And it's obviously clear that with the new V-9, we can't beat him at the rate we've been going," Stephen responds.

"Okay. I agree, but where are you going with this?" Nora asks.

"We need training. And not just from ourselves. There are powers we have that we haven't mastered. And I've been thinking that maybe we need to learn how Godspeed thinks, and how he's going to react to situations, if we're going to have any chance of beating him," Stephen says.

"Okay…" Nora responds, still not sure where he's going with this.

"So, to sum it up, we need a teacher. Someone who can teach how to really be a speedster, who can teach us secrets of the Speed Force that we don't know, teach us how to get faster, and how to think like an evil speedster," Stephen says, looking knowingly at his sister as he says this.

Nora's eyes widen as she finally catches on to what her brother is saying. "No! Absolutely not!" Nora shouts.

"Sis, calm down! I know this is less than ideal. I'm not exactly happy about doing this either. But we need to know how to get faster and beat Godspeed, and like it or not, Eobard Thawne is our best chance," Stephen responds.

"You really think Thawne's gonna want to help us? He's called the Reverse Flash for a reason! He's Dad's greatest enemy! Why would he ever want to help the Flash's kids?" Nora responds.

Stephen stands there for a moment, quietly staring at his sister. Then, in an extremely calm voice, he asks, "Is this really just about you thinking that he's not gonna help us, and that he was Dad's enemy? Or is there something else going on here?"

Nora looks at her brother, then cries angrily, "Of course there's something else going on here! He killed our grandmother, who I'm named after, and got our grandfather thrown in jail! He brought nothing but pain to Dad, and it's because of him that Dad disappeared! We became orphans because of him! And he almost killed Auntie Kara! He almost took the woman who's been like our second mother from us! I don't ever want to see him, let alone have anything to do with him! All I want is to hear that he's finally been executed!" Despite the fierce anger in her voice, Nora's eyes are filled with tears by the end of that rant.

Stephen stands there before reaching out and pulling his sister into a hug. "I know. I know, Sis. I hate Thawne too, and I would take any other option if possible." He then pulls back and looks right into his sister's tear-filled eyes before continuing, "But we don't have a choice. We can't beat Godspeed on our own. We need help. If we don't, lots of people are gonna die, and the United States is gonna fall to Godspeed. I know how much you hate Thawne. But I'm willing to put my hate for him aside if it means saving people's lives and saving this country. Are you willing to do the same?"

Nora looks back into Stephen's eyes for a moment, then finally nods. "Yeah. I'll do it," she says. She then leans into her brother and just cries for a minute, and Stephen just holds her, knowing she needs this opportunity to vent.

(Iron Heights prison)

Stephen and Nora race towards the prison, knowing the layout from past trips there, mainly by helping get metahumans there. Now, they're going to Iron Heights for a very different reason.

They race into the metahuman wing, and head to the maximum security section of the prison, where the strongest metahumans are kept. They have always avoided that area, but now know it's finally time to visit it.

They race past the doors and quickly knock out the guards. They then face the door, glance at each other, then open the door into the maximum security ward. Nora takes a deep breath, and they walk in.

Once in, they turn to the first cell on the right, and Nora calls out, "Eobard Thawne!"

For a few moments, there's silence. Then, inside the cell, slowly, Eobard Thawne walks into view, wearing a yellow prison suit with a black chestplate on. He slowly turns to them, revealing the false face of Harrison Wells.

"Well, well. If it isn't XS and the Silver Flash," he says in a low voice. He looks at them before saying, "You may as well take your masks off. I already know who you are. Nora and Stephen."

The twins look at each other, then sigh before Nora removes her mask and Stephen pulls back his cowl. The twins look at Thawne, who is still impassively staring at them.

"Hmm. You both look a little bit like your father," Thawne observes.

"Don't mention our father!" Nora snarls. Thawne remains impassive, and Stephen puts a hand on Nora's shoulder to calm her down.

Nora takes a few deep breaths to calm down. Feeling like it would be better for him to do the talking, Stephen takes a step forward and says, "We're not here to chit-chat about our father, Thawne. We're here because we need your help."

Thawne raises an eyebrow. "Well. Your father may have asked for my help a few times, but I never expected this from you. And you seem to be doing rather well as speedsters on your own. Trained by Supergirl, I imagine. Why come to me?"

Nora clenches her teeth a bit as Thawne mentions Kara, but keeps her mouth shut.

Still calm, Stephen responds, "Because. We've been fighting a new speedster who calls himself Godspeed. His speed is beyond us, and no matter what we try, we can't keep up with him. And now, thanks to the fact he's created a speed drug, he's faster than probably even you or our father. And we need help to stop him."

"Again, why come to me?" Thawne asks.

"Because you're our only hope at stopping Godspeed!" Nora cries angrily.

Thawne raises an eyebrow, looking between the twins. Then, he says, "Really? I'm your only chance? There aren't any other speedsters to help you?"

"You know d*** well there aren't! Jesse Quick and Jay Garrick died in the Decimation, our father is gone, and our uncle isn't in any condition to teach us! You know more about the Speed Force than practically anyone, and according to what our Auntie Kara told us, you were the first speedster to solve the speed equation! If there's anybody who can teach us the secrets of the Speed Force and can help us get faster, it's you!" Nora somewhat explodes.

Thawne looks at Nora for a moment before responding, "You may be correct about my ability to help you. But the question remains: why would I?"

Nora looks ready to phase through the cell and start beating the crap out of Thawne. However, Stephen steps forward and says, "Because. If Godspeed takes over the United Sates, then he will not stop until he has taken everything he can from me and my sister. And once he has done that, he will kill us. And once we are dead, he will come for you. He will offer you the chance to join him, and if you won't, he'll kill you. He won't let there be a speedster out there that can threaten his reign."

Thawne looks at them for a moment, considering Stephen's words. Then, he asks, "How do you expect me to train you from inside this cell?"

"Well, we're not going to break you out, if that's what you're wondering. But, we can continue to visit you like this, and I know that the plinth in your cell can take calls. You can walk us through some of our training via comms. And maybe, if you can actually help us stop Godspeed, then maybe you can begin to earn a fraction of our trust," Stephen says firmly.

Thawne looks away from them, slowly walk to the right side of the cell. Then, Nora, calming down, and hardly believing she's saying this, says, "Please, Thawne. Please help us."

Thawne remains still, staring at the wall before turning to the twins. He stares at them for what feels like an eternity, before he finally says, "Alright. I'll work with you. But even if I train you, it won't make you fast enough."

"Then how do we get faster? You solved the speed equation! You can tell us how!" Nora says.

"No, I can't," Thawne responds. Nora is about to blow up at him when he adds, "I can show you."

Stephen and Nora look very confused. Thawne then says, "Go to the Flash museum. In the hallway leading to the Hall of Villains, there is a secret room that can be accessed by touching the right section of wall. Inside, there is a plinth. It will show you the answer you're looking for."

Stephen and Nora look at each other, wondering if they should believe Thawne. Then, Thawne says, "I imagine the guards will be awake soon. You should go. I assume I will be seeing you again soon."

Stephen and Nora look at each other, then nod before they race off, heading for the Flash Museum.

It doesn't take them long to get there. Once they reach the right hallway, they stop and begin searching the walls, running their hands along it to try and find the spot Thawne mentioned.

Then, after a minute, Nora suddenly feels something under her hand. The wall around her hand glows, and beside her, the wall parts to reveal a hidden doorway. She looks back at Stephen, then slowly walks in, Stephen following right behind her.

Inside the room, the twins look around in amazement. It's filled with multiple objects that they recognize. Old uniforms from their dad's former teammates. Several old Flash suits. And several other objects that looked like they were potential exhibits that were being kept in storage.

Then, on the far side of the room, Stephen spots the plinth that Thawne mentioned. He slowly walks up to it, seeing a circle on the top. Slowly, he reaches out and places his hand on the circle. It begins to glow, and a second later, between the plinth and the wall, a hologram of a woman's head suddenly appears.

"Good evening, Stephen Allen and Nora Allen," the head says.

The twins jump back a bit, a little surprised. Stephen quickly responds, "Umm, hi. You know who we are?"

"Of course. Stephen Pietro Allen and Nora Caitlin Allen, son and daughter of Barry Allen and Wanda Allen, also known as the Flash and Scarlet Witch," the head responds.

"She knows who we are," Stephen whispers to Nora, who just nods in amazement.

Stephen looks back at the head and asks, "And who are you?"

"I am Gideon. An interactive artificial consciousness," the head responds.

"Okay…Gideon. Well, we have been sent here because we were told that you held the answer to the speed equation," Stephen says, hoping that that will be enough information for Gideon.

"Of course. Accessing archive," Gideon responds before her head disappears, replaced by a hologram of a multitude of equations and diagrams.

Stephen and Nora both walk forward, looking at the new display. After a few moments, Stephen realizes what he's seeing.

"Thawne unlocked the secret of how to harness the power of tachyons," Stephen says in an awed voice.

"And if we can follow this, we can do the same. And if we can harness tachyons, we should be able to match Godspeed's speed, or at least get close," Nora adds.

The twins look at each other, beaming. Finally, with Thawne's help, they may have the edge they need to stop Godspeed.

And, I'll end there.

So, Thawne has finally been introduced. I decided to keep him in the mentor type role he played for Nora in the show, as I figured that would be the best way for Nora and Stephen to learn about time travel, and set up a future fight with the Reverse Flash in a future story.

So, as you saw, I included a few hints as to what's happened to our favorite characters since the Decimation. So, Barry is gone, and has been for a while. And, though I won't show it at any point, Reverse Flash has had a run in with Kara since the Decimation, and almost won. And, if you couldn't tell from Nora's words early on, Kara is the one who mostly raised Nora and Stephen. You won't find out why exactly until the Endgame story. Also, when Nora said "our uncle", she meant Wally, not Pietro. You'll also learn why Wally is in a bad state in the Endgame story.

Well, I hope you all liked this chapter. Give it a review, and stay tuned for the next chapter!
