I--I didn't mean to do it,

I was just frustrated I couldn't catch up,

and then it just happened.

I've never seen artificial lightning interact

with organic lightning like this before.

Okay.

That's disturbing.

We should--we should go over your biometrics,

Yeah.

I--I can't, I have to head back to the lab.

My speed is running out.

Fiery Frances Sumner.

Still, according to Gideon, your empathic capacity

is up 1,000 percent.

Your brain just got supercharged.

Usually, when I sense a wave of fear and panic,

it just hits me like a train.

Like when we fought Blockbuster?

Exactly, except this time when my powers kicked in,

I barely broke a sweat.

Which is all very badass, but is anyone else

wondering how the heck this happened?

Well, I mean, I don't know.

My powers have changed before, like when Jenna was born.

Maybe it's just natural.

It's possible, but let's run some more tests

just to make sure.

- Barry? - Hm?

I can feel a massive wave of concern wash over you.

You're worried about something. It's way more than just me.

It's the new speedster I'm training, Meena Dhawan.

During our last training session,

I got struck by her artificial lightning.

Now, it was an accident, but when it hit me,

it collided with my lightning and it set off

some kind of a biokinetic chemical reaction.

Okay, accidental attacks, artificial speed.

Is she about to go all Spock Flash?

No, I don't think so.

I mean, Meena did find a way to generate

her own speed source artificially,

but it's not affecting her like it did me.

I mean, her emotions seem fine.

So it's just her powers that are funky.

Well, maybe you should throw 'em over

to Fast Track Labs, take a peek at the generator?

See how her speed machine really works.

Barry Allen?

- Yeah. - Sorry to keep you waiting.

No, no.

- How can I help you? - Yeah, actually,

I am here on behalf of a mutual friend

who likes to run fast.

- Oh. - Yes.

Our friend was hoping I could take a look

at your-- your special project.

He thinks it'd be a good idea to get a second set of eyes

on this, just to make sure everything's safe.

I understand.

And he's right.

I could use another scientific eye on all this right now.

- Okay. - Follow me.

Yeah.

There she is, my pride and joy.

Wow.

Is that an oscillation chamber?

It's a biometric lightning

oscillation chamber, technically.

We call it the B.L.O.C.

It's built with quantum computing

to remotely harness lightning

from the Earth's upper atmosphere

and turn it into artificial speed.

This equipment is decades ahead of any other lab.

Oh. Including yours, I hope?

I can't take full credit for all this innovation.

Sure, I can handle the physics,

but my colleague is more familiar

with the nuts and bolts.

Ah, there he is.

Yeah, you know The Flash, don't you?

- No, I-- - Do you two--

Have you met before?

You go to hell!

You're taking both of us there!

Now who's the villain, Flash?

Now who's the villain?

No. I mean, I don't-- I don't think so.

But my memory is a little hazy. - Yeah, um,

Eobard suffers from a rare form of retrograde amnesia.

- You're kidding. - I just--

I have trouble accessing memories

Anything over a year ago, all I get are occasional flashes.

Well, nobody's perfect.

Wow. You really are something.

I'm starting to think all this is just,

When calculating quantum static in genetic speed,

I have been working on this for months.

No one's even come close.

Well, the other candidates were idiots.

I'm not.

Which is how I can tell, you're trying to create a speedster.

I can help.

How are you still here?

Well...

I wanna see how this ends.

Don't screw with me!

How did you get your speed back?

- I didn't? - Stop lying!

I saw you, five minutes ago, 1,000 miles from here wearing

your original face, pretending you didn't remember me.

So, who is he?

A version of you from your past?

Answer me!

I don't know.

And I don't care.

Don't you get it?

You took my speed.

There's no other versions of me out there,

no other tricks up my sleeve.

You took everything from me.

So, why don't you just leave me alone?

When you were nearly erased during Armageddon,

it erased your past didn't it?

Which means he must be from another timeline.

Like when I created Flashpoint, there was another Thawne.

I need you to kill my mother.

With pleasure.

The only way to fix things was to let him go.

When you fought with the Legends,

he tried to keep himself from getting erased,

but Black Flash caught up to him.

I guess he didn't finish the job. Here's a suggestion:

Why don't you go bother him?

The other Thawne built this.

Does that mean anything to you?

He didn't build that, that's mine.

That's my biometric lightning oscillation chamber

that I built two centuries from now,

when I was a younger man to see if I could

become a speedster like you.

- It worked. - But not the way I intended.

Has it tapped into the negative speed force?

Ahh!

That's why Meena's powers are so erratic.

They're not artificial, they're negative.

I've seen what that kind of force can do.

- Who's Meena? - Dr. Meena Dhawan,

she's the one that's using the B.L.O.C.

Never heard of her.

And guess what? Neither has history.

So, I guess your new adversary made sure that

this Dr. Meena Dhawan never sees the future.

Because if she keeps using that device,

the negative speed force will start to alter her personality.

It'll destroy her.

Not if.

When.

There's one thing you should know about us Thawnes,

Allen, no matter when we exist,

no matter what our memories are,

we only look out for ourselves.

So whatever this new guy's endgame,

he'll sacrifice every pawn on the board

to get what he wants.

Not if I stop him before he has a chance.

Well.

Pretty cleared up for the night,

just two heat signatures inside.

- Meena and Thawne. - What's the 4-1-1, boss?

now he's pumping Meena with negative speed.

- If you need backup-- - No, it's too dangerous.

I don't know why he's doing this,

but I won't let anyone get hurt.

Artificial speed saturation at zero.

Ready for infusion. - Doc.

You set the oscillation levels at 52 million joules,

that is more speed than you have ever absorbed before.

Are you sure The Flash would want you to do this?

He's why I'm doing this.

I hurt him this morning when my speed started to run out--

I--I need to make it last longer.

All right.

Activating electrostatic fins.

Ready for biometric absorption.

Meena, stop!

Flash.

What are you doing here?

Flash, I know what happened today,

and I know how to fix it.

No, you don't.

I know why you attacked me.

It's because your speed is connected

to the negative speed force. - Wha--

It's an extra-dimensional power source

The B.L.O.C. is fueled by lightning

from the upper atmosphere.

We've run the numbers a thousand times.

Then your math's wrong.
