BARRY: I let it happen again.

I trusted someone I shouldn't have.

Jay Garrick.

Zoom.

Just like I trusted Harrison Wells.

Or Eobard Thawne.

You see what I mean?

I made the same mistake twice.

I thought they wanted to teach me
how to use my powers,

train me to get faster,

but they didn't come here to help me.

They came to use me,
and take everything I love away from me.

But no more.

I'm gonna crack the code.

Figure out how to improve my speed.

I'm going to train harder,

get stronger, and run faster
than anyone's ever run before.

And then I'm gonna stop Zoom.

Come on.

(PATTY SCREAMING)

BARRY: Oh.

Can we please get rid of Jay's helmet?

No. Sorry, it keeps me motivated.

Well, it's giving me day-mares.

This is everything I could find
even remotely related to increasing speed.

How are these supposed to help
apply the speed equation to you?

The answer's got to be here somewhere.

I think I found something interesting.

Good interesting or bad interesting?
'Cause that word could go either way.

After running some comparative data,
it appears that you, Reverse-Flash,

and Zoom are moving your legs at,
essentially, the same speed.

Then why are they so much faster than him?

Best I can tell, with each stride,
their feet spend less time on the ground,

thus propelling them forward much faster.

By almost 30%.

Great. All right, well,
I gotta make up that difference somehow.

Barry?

Look, after what that monster did,

I want to stop Jay
just as badly as you do.

Right.

But what if the reason you haven't been
able to run as fast as him yet

is because you just can't?

Barry, you know what happened to Jay
is not your fault, right?

Well, I should've known better.

You?

With Wells last year,
I should've learned my lesson

and dug deeper into Jay.

-But I didn't.
-Come on, Joe.

Point being is,
nobody saw this coming.

-Nobody.
-(OVEN TIMER DINGS)

(GRUNTS)

So,

I

kind of went on a date.

-With who?
-The new editor at CCPN.

Scott Evans.

Your boss?

Okay I'm... It wasn't like that.

He's a really nice guy,

he's sweet, and smart, and...

What?

I just...
It all makes me think about Eddie.

I think about him every day, Barry.

It just feels wrong.

I know for a fact that
Eddie would want you to find love again.

Yeah, I know, but--

BARRY: Look, Iris.

You're the only person who's gonna know
when you're ready to move on.

But, until then, don't keep yourself
completely closed off, you know?

You're gonna miss out on something great.

Yeah.

(DOOR OPENING)

-Hey.
-Hey. Sorry, I'm late.

No. No, you're just in time.

-Ow, ow, ow, ow, ow, ow, ow!
-Dad, mittens!

(WALLY LAUGHING)

WALLY: So,

my advisor loved my engine designs,

and even asked me to help her out
with one of her engineering projects.

Okay, big man on campus.

It's not that big a deal.

It's a great opportunity
and you should take it,

because life doesn't give those out
all the time.

Isn't that right, Barry?

Yeah.

Yeah, what is the project about?

It's trying to push the speed limits
with smaller propulsion systems.

-Yeah. That's cool.
-Where do you even start?

Well, I really like to read the journals
of the classic engineers.

So, their engine designs,
how they increased horsepower,

and learn from the best, I guess.

-You read their journals?
-Mmm.

I mean, it's not like
I can just go and talk

to Enzo Ferrari or Ferdinand Porsche,

'cause they dead,

-(BOTH LAUGHING)
-but you know,

doesn't mean they can't still teach me.

-I got to go.
-You haven't even touched your food.

(STAMMERING)
Yeah, no, I'm sorry, I just...

I just realized the key
to a case I've been working on,

so I'm gonna just...

Thank you, Wally.

Whew! Um, sorry, guys, I'll be...
I'll be back later.

That dude gets weirder
every time I see him.

Yeah.

CISCO: You mean the old Harrison Wells.

As in Eobard Thawne.

You want him to teach you
how to run faster?

-Oh, that's rich.
-How are you gonna do that?

By running back to a time last year.

And what about the other you?
The one from that other timeline?

I'll knock him out with something.

I mean, it's not like he'll see me coming.

And then I'll have Wells teach me.

Barry, that's crazy.

Nothing I've read
is pointing me towards a solution,

and if there's anybody that's figured out
the key to getting faster, without V-Nine,

it's him.

What do you guys think?

(SCOFFS)

Your plan is asinine.

Did you find Jesse?

Does it look like I found Jesse?

How many times
have you traveled through time?

A few.

Do you have any idea
how many things you could screw up?

All I need is one conversation
with Dr. Wells.

-He's not Wells! I'm Wells!
-BARRY: Thawne.

This man has been studying you
for 15 years.

For 15 years.

And you don't think
he's gonna know who you are?

Barry's pretty good
at impersonating himself.

You should've seen him
over there on Earth-2.

I was like,
"Somebody, get this man an Oscar."

He will know, Allen. He will know.

BARRY: All right,
then what am I supposed to do?

I mean, how am I supposed to stop Zoom?

Do you know the answer to this equation?

If Thawne figures out that it's you,

the timeline will be altered,

people can die.

Others could live, and no one will know
who or what will be affected,

but I promise you, when you come back
things will be different.

And only you will know
what those differences are.

Well, if that's what I have to do
to stop Zoom, then so be it.

Because if I don't, and Zoom gets my speed
before I learn how to stop him,

everybody I care about,
everybody in this whole city,

their world will never
be the same, anyway.

I...

Do you really think you can do this?

Yeah, I do.

When I went back last year,

and I saw my mom die,

it didn't affect the timeline.

Yeah, but you haven't really
time-traveled on purpose like this before.

I have to do this, you guys.

Okay. Let's go for it.

CISCO: Okay,
you're gonna go back to the time

when Wells was distracted by the return
of the major jackass, Hartley Rathaway.

This is the first time we found out
Wells knew the accelerator might explode,

and we were all angry with him.

So, anything that might seem odd
about your behavior,

Wells should attribute to that.

Also, remember,
do not underestimate Hartley.

He almost killed you.

This is a tranq dart that should knock
old-you out for about six hours.

Which lines up perfectly
for when you're going back,

because not much was happening,

until Hartley attacks
the Cleveland Dam that night.

So, that should give you time
to learn what you need and return.

CISCO: One more thing, you cannot tell us
the truth about Wells. No matter what.

You must keep the timeline intact.

It's gonna be hard to course-correct
if anything gets altered.

So, get what you need, and come back,
preferably to this moment,

this exact time you're leaving,
or else you might set off

some kind of Twelve Monkeys time loop
you'll never get out of.

Mmm-hmm.

-No pressure.
-Yeah, cool.

So, we'll see you in, like, two seconds.

Time travel's so weird. (LAUGHING)

-Godspeed, Barry.
-I'll be fine.

What could go wrong?

IRIS: Eddie!

(GASPING AND GRUNTING)

Oh, no, I'm too early.

HARTLEY: You know my name.
I know some names, too.

This is not a good start.

HARTLEY: (OVER COMMUNICATOR)
Caitlin Snow. Cisco Ramon. Harrison Wells.

-(BUZZING)
-(GRUNTING)

Something's interfering with his comms.

Barry!

Come on.

Damn it.

-What's happening?
-I don't know.

Whatever Hartley's using
must be shorting out his comms.

HARTLEY: I can hear the radio waves...

Yeah, yeah, yeah, I remember this.

HARTLEY: ...emanating from your suit.

This could still work.

HARTLEY: About 1900 megahertz.

Are they on the other end? Listening?

Will they hear you die?

No. They're gonna hear you

-get your ass kicked.
-"Get your ass kicked."

(CHUCKLING) Okay.

Is that all it takes to scare you off?

-(BOTH PANTING)
-HARTLEY: And he chose you over me?

My comms? Who are you?

I don't have time
to explain this to you right now.

I don't understand, you're me!

I'm sorry, I have to do this.

This will all make sense eventually.

Where are you, oh, chosen one?

Got you, again.

Looks like you're not as smart
as everyone says. Huh?

Smart enough to have figured out
who Harrison Wells really is.

You see, I know his secret.

CISCO: (OVER COMMUNICATOR)
Barry? Are you there?

Yeah.

Yeah, I'm back.

I'm bringing Hartley in.

Scanner's picking up
foreign metallic objects in your ears.

-Take them out.
-I can't.

I suffered head trauma
when S.T.A.R. Labs exploded.

My hearing was severely damaged.

Without these, I am in pain
you can only imagine.

Cisco, see if the devices in his ears

are generating any
low level electromagnetic pulses.

You want me to scan for E-bombs?

I just...

I mean, don't you think
that could have been

what was interfering with the comms?

Well, well.

Trying to go all Mission Impossible on us?
Use those things to bust out of here?

(DR. WELLS SPEAKING LATIN)

Pump in some sound stimuli
to counteract his tinnitus.

Then we'll make some
non-explosive replacements for him.

Deal with you later.

Take them out, Hartley.

Now.

BARRY: Dr. Wells.

So, that was quite an observation you had
about Hartley in there, Mr. Allen.

Yeah, just seemed too easy,
taking him down, you know?

Mmm-hmm.

Well, likely reason for that
is you're getting faster.

Actually, I wanted to
talk to you about that.

It occurred to me that

maybe we've been going about
improving my speed the wrong way.

How so?

Well, I've been learning
different techniques involved in running,

and I was thinking that there's
just as much science involved in speed

as anything physical or technical.

I just can't figure out
how to apply it to me when I run.

Thought if anyone could help me,
it'd be you.

This is quite the

speed equation you've concocted here,
isn't it, Mr. Allen?

Yeah. I've been doing
a lot of reading in my down time.

What on Earth inspired you
to adopt such a, what shall we call this,

unorthodox approach?

I just know that
I'm not the fastest man alive.

I need to be faster, a lot faster,

if I'm ever gonna be able to
take down the Man in Yellow.

So, what do you think? Can you help me?

Let me see what I can do.

EDDIE: Hey, Joe.

JOE: Hey, Eddie.

Must've been a good lunch.

Iris is the first girlfriend
I've ever lived with,

so it's all very new and exciting.

"New"? Yes. "Exciting"? No.

Sorry. Somehow, I keep forgetting
you're her dad.

Right, try to remember.
For both our sakes. Come here.

I was thinking about
what you said about Wells.

How there's something off about him?

I need you to do something for me,
off the books.

Joe, come on.

Just trust me, Eddie.

Okay. What?

Go back to his house. Search everything.

Someone there?

(SCREECHING)

(MAN YELLING)

What the hell?

(BEEPING)

C.C.P.D.

I'm sure they have it handled, right?

No.

You need to go.

Run, Barry.

(PANTING) Is everyone okay?

-Barr.
-Yeah?

You should cover that up.

Oh, right, yeah.

-Thanks.
-EDDIE: Joe.

No sign of it outside.
It just disappeared.

Hey, Barr.

Hey, Eddie.

Any idea what that thing could be?

What the...

No, I don't... No, not yet.

Um, if I figure it out, I'll let you know.

Things just keep getting
more and more strange in this city.

Yeah, they do.

I'm gonna check in with Iris,
let her know I'm okay.

-Great.
-All right, see you, Barr.

What the hell's going on with you?

What are you talking about?

Look, I know you told Iris
that you love her,

but you said you'd moved past
this whole Eddie and Iris thing.

I have, Joe. I have.

Then why were you being so weird to Eddie?

Okay, look. I'm sorry.

Let me, uh,
just take care of all this, okay?

I'll talk to you later, I promise.

Fine.

But soon.

Soon, yeah.

What's going on?

CISCO: Oh, you know, just trying to
figure out how to find this Dementor

that's apparently roaming
through Central City, right now.

I assume that was the cause
of the C.C.P.D. alarm?

Yeah. Actually, it attacked my lab.

CAITLIN: You saw it?

No, I didn't see it. No, I did...

Um, well, I didn't get there in time,
but I have seen it before.

Where?

It was earlier today, actually,
when I was running to take Hartley down.

Uh-huh. You're just mentioning this now?

I didn't...
I mean, I didn't know what it was.

I thought it was some sort of illusion?
I don't know.

Okay, well we need to find it
before it hurts somebody.

Yeah, can you track it?

What is it with you guys?

It's like you think
I have ESP or something.

I can't just magically sense
where things are.

What can you do, Cisco?

I'm thinking I can reconfigure the
S.T.A.R. Labs satellite to look for it.

It might take some time, though.

Do it.

In the meantime, Mr. Allen,
come with me.

Have a seat.

Is this about the speed equation?

Matter of fact, it is.

Great, okay, good.

-So, you've figured it out?
-Mmm-hmm.

(GRUNTS)

Yes.

I figured it out.

Now, who are you?

I mean, who are you, really?

Dr. Wells, what are you doing?

None of it adds up.

The interference with the comms.

The speed equation. The Time Wraith.

That's what we call them.

Time Wraiths.

Scary, aren't they?

I thought,
"Oh, no, a Time Wraith has found me."

But then I thought, "No, no, no.

"You know what you're doing."

"No, the Time Wraith is after someone
who's traveled through time,

"and doesn't know what they're doing."

(LAUGHING)

Dr. Wells, come on, it's me, it's Barry.
I don't--

DR. WELLS: Really?

You are good.

You are good,
and I would believe you, except that...

Nothing?

I move like this, you barely flinch.

You know who I am.

Don't you?

Oh... (LAUGHING)

And you're from the future.
Do you know how I know that?

Because I haven't taught my Barry Allen
how to phase through objects. Yet.

(LAUGHING)

Let me out of here, Thawne.

I know.

You're upset.

But it does me good
to hear that name again.

Now, onto the bigger question.

Why are you here?

Because I want to go faster,
and you're the only one who can teach me.

You're the only one
who's figured out the equation.

The Speed Force.

You've manipulated it.

How did you do that?

No.

No, no, no, no, no, no, no.

No.

You'd only come here
if something went wrong.

If you're still alive,

then that means...

I haven't beaten you.

If you're still alive,

that means my plan fails.

And if my plan fails,

I don't get to go home,
and if that's the case, well then--

No, no, no! Hey, hey!

It's the opposite, it's the opposite!

You trick me, you harness my speed.

We turn on the accelerator
to create a path for you to go home.

I go back in time.

You go back to yours.

You won.

Yeah.

Then why are you here?

Why are you here, now?

Because when I got back,
a Singularity had formed.

And now, the only way for me to learn
how to get faster

and stop the Singularity from happening
was to come here, now.

Well, that's good to know.

(BREATHING HEAVILY)

There's just...

(SIGHS)

Just one thing that occurs to me.

I don't need you.

Do I?

Not this you, certainly.

Oops.

You probably should have thought of that,

before you came back here.

Shame.

You ran all the way back here

just to die.

You kill me?

Barry?

This Barry? Your Barry?

He learns it all.

There's a hidden letter,

telling him how it ends, how to beat you.

Everything.

Anything happens to me,

you never make it back home.

Go on.

Kill me, Thawne.

See how this all ends.

Now,

you're gonna help me get faster.

(RICK ASTLEY'S NEVER GONNA GIVE YOU UP
PLAYING OVER SPEAKERS)

Please.

I want to know how these work.

I'll tell you, just kill the music?

-(BUZZING)
-(GROANING)

-Thanks.
-The gauntlets, Hartley.

What kind of frequency is this?

(RATTLING)

(RUMBLING)

(SNARLING)

CAITLIN: (GASPS) Cisco, it's here!

(PANTING)

It's coming!

-Inside the cell. Now!
-HARTLEY: Uh, sorry, what's coming?

Holy Harry Potter.

Okay! Well, isn't this fantastic?

Look. We're gonna be safe in here,
these cells are--

-(TIME WRAITH SNARLING)
-(GLASS CRACKING)

Impenetrable?

Barry! Doctor Wells!

BARRY: Uh, we have to help them.

You let it track you here!

Get me out of here, come on!

If that thing comes after me
and messes with my plans,

you're all dead!

Where are they?

Okay. Step back.

You'll shatter the glass!

You got a better plan?

As a matter of fact. Give me those.

-(THUDDING)
-No!

Now, Cisco!

What're you gonna do?

These cells have speakers
linked throughout S.T.A.R. Labs.

Yes, and?

I rigged these gauntlets
to emit a destructive signal

if they were ever disarmed.

(SHRIEKING)

If I can just find the right frequency
of whatever the hell that thing is,

well, let's just say you'll be glad
you're in here with me.

-(LOUD BUZZING)
-(SHRIEKING)

(BOTH PANTING)

I'm sorry that we didn't come sooner.

It's alright, Inky's gone.
I don't see anything.

You know, we'd be toast if it wasn't
for Hartley and those gauntlets.

Well, self-preservation
is a very strong motivator,

but he stays in the cell
until I say otherwise.

Okay, I'm just saying.

So, the two places the thing
has attacked are here and C.C.P.D.

-The common denominator being--
-Me.

Yeah, I know. I just... I don't know why.

Well, you must've done something
to piss him off.

Satellite hasn't found anything.

We need to find a more permanent solution
to this problem.

Start by repairing Hartley's gauntlets.

That's as good a first step as any.

-I got some parts for it.
-Let's go for it.

-You don't know how to stop a Time Wraith?
-None of us do,

that's why we always
try and avoid them in our travels.

-We?
-Speedsters.

We're not the only two
out there, you know.

This isn't the first time
I've time-traveled.

How come I've never seen
one of these until now?

Because you ran out of luck.

And Time Wraiths hate it
when speedsters manipulate the timeline,

and now that thing's gonna do
everything it can to end you.

(SCOFFS)

Here's what we're gonna do.

You're gonna go to C.C.P.D.,
you're gonna see what you can find

to help us stop this thing,
I'll do the same here.

What am I supposed to be looking for?

You're in forensics, figure something out.

Hey, but what about the equation?
Me getting faster.

If we don't stop this thing,

there's gonna be no point
in me teaching you anything.

No trace elements, no prints,

no sign that it was ever here,
except the whole mess.

Any idea what it was looking for?

-Me.
-What? Why?

It doesn't like something that I did.

And what exactly would that be?

Joe, Singh needs you in his office.

Hey, Eddie. Do you have a second?

I kinda gotta go,
check out a lead for Joe.

Okay, actually,
this is for Iris' birthday.

That's two months from now.

Yeah, no, I know, you're right. I just...

Um, I wanna make a video montage for her.

Just everybody in her life, and how her
being in your life has made it better.

That sounds great, yeah.
I'll think of something to say.

Can we do it now?

Barry, I really gotta go do this thing.

-I know, I kind of have to get it today.
-Sure.

All right, great.
Just, um, speak from the heart.

Talk as if it was the last thing
you could ever say to her.

Okay.

Go ahead.

What does Iris mean to me? Wow.

So, can these gauntlets be salvaged?

Their electron guns are fried.

So, it shorted the wave tubes,
destroyed the amplifiers.

Yeah, but, to be honest with you,

I don't know how to manipulate
the frequency variance.

Hartley would know.
He's the one who did it.

See if he can help,
but he stays in the cell.

But then what?
That thing's gonna come back.

I don't know.

Where is he?

Where's the other Flash?

I'm right here.

Okay, not how I expected
today to turn out.

Yeah.

-Who are you?
-Who is he? Who are you?

-I'm Barry. I'm Barry. Your Barry. He's...
-Your doppelgänger.

No, not yet.

I am you, Barry. Just different.

Wait a second, how do we know
which one's the real Barry?

Dude, okay, I've watched Wrath of Khan
with you, like, five times.

Imposter.

Yeah, and every time at the end,
you turn to me and you say,

"I have been, and always shall be,
your friend."

Ah-ha! You imposter.

What is going on here?

Okay, guys, I'm sorry.
This was not supposed to happen.

The tranq dart that Caitlin made
was supposed to last a lot longer.

I did not give him a tranq dart.

Okay, no, yes. Not you.
The you from the time that I'm from.

The time that you're from?

I think what he's trying to say is,
he's from the future.

-The future?
-Yeah.

-The future? With the...
-Yes. Yes.

Are we saying I can time travel?

(SCOFFING) One day.

Oh, that explains the white on the symbol.

But wait a second,
suppose we now change your emblem?

Will it be because we got the idea from
this, or, I mean, that would mean that--

Stop talking. You stop talking, too.
All right?

The more you say,
the more the timeline is disrupted.

Now, I'm going to assume
that your presence here

-is the reason that thing is attacking us?
-What? What thing?

Have you ever seen The Frighteners?

It's sort of like that, but scarier,
and faster, and it's after you. After him.

Yeah, it's been chasing me
ever since I got here.

-Okay, so how do we stop it?
-We don't know.

-Then what are we gonna do?
-The one thing we can.

What? What are we doing here?

We're here for the answer
to your speed equation.

The reason that you
traveled back to this time.

And the key to running faster.

Tachyon enhancement.

This was not the deal.

If you think that I'm gonna
hold your hand this entire way,

you're sadly mistaken.

Everything you need is on this drive.

If you follow its instructions,

you will enhance the Speed Force
in your system and run faster

than you ever thought possible.

BARRY: If this doesn't work,

I'm coming back.

CISCO: Doctor Wells, we need you.

Time to go home, Flash.

Okay, our satellite has finally found
our floating friend, and it's coming back.

-You need to go.
-I need to know how to stop it.

-Barry.
-Not now.

When I get back,
you guys have a year to figure it out.

Okay, we'll figure something out.

Cisco, come here.

Hartley knows where Ronnie is.

Okay. What?

-It's coming.
-You need to leave, now.

Thank you.

CISCO: Barry, here it comes.

(SHRIEKING)

It's not working, it's slowing him down.

Not for long.

No. Barry!

(GROWLING)

(PANTING) Cool.

-It's coming.
-Did you even go?

-The Time Wraith.
-That's a good name.

-Looks like that's a "Yes."
-Did you figure out how to stop it?

(SHRIEKING)

Damn. We thought so.

Barry.

(SHRIEKING)

I suddenly realized.

Low frequency, high intensity.

-I knew that.
-Oh, hey, Barry. How was your trip?

So, aside from the fact that a Time Wraith

came over here and nearly killed us,
how did it go?

It was interesting.

Good interesting or bad interesting?
'Cause that could go either way.

-So far, so good.
-(SPEAKING LATIN)

How many times
do we have to tell you, Hartley,

ever since evil Wells
got erased from existence,

no one speaks Latin around here, anymore.

Well, as always, been a pleasure working
with you all on this little project.

If you need anything in the future,
call me.

-I'm off to a late dinner.
-Dinner? Anyone special?

Very.

My parents.

So? You got me on
pins and needles over here.

What about the speed equation?
Did Wells tell you what you need to do?

Well, let's see.

Mmm. Maybe it's password protected?

Are you kidding me?

After everything I just went through,
this doesn't even work.

We got it.

Hey.

-Hey.
-You okay?

Yeah, I'm okay.

Although, it turns out it's easier to find
a two-ton gorilla on this Earth

than a teenage daughter.

I don't know what I've done.

You did what you thought you had to do.

You risked your life to save her.

You brought her here
to protect her from Zoom.

You acted like a father.

Like a father.

You know, my wife had to...

She had to talk me into having kids.

Kids, you know, they're small,
they're loud, run around.

All I needed was my science,
my job, for my joy and happiness.

And then,

(SCOFFS)

the moment we had her,

all that I wanted was her love.

Now,

I don't know if I'll ever see that again.
It seems every decision I've made lately

has backfired on me.

You just have to trust that
in the long run,

you've made the right ones.

-Hey.
-IRIS: Hey.

I put your plate from dinner
in the fridge.

Thanks.

It's been almost a year already.
Can you believe that?

That's the thing, Iris.
Everything keeps moving forward.

The question is, when will you?

I don't know, Barry.

Well, um, I found something
that I think might help.

I was putting together this little video
montage for your birthday last year

with everybody and...

Everything happened. Um...

But, uh, take a look.
I think it might help.

Okay.

What does Iris mean to me? Wow.

You know, a lot of times

I have a hard time
figuring out what to say to people.

But, when it comes to you, Iris, I don't.

Because with you,
everything that used to feel tough

just doesn't anymore.

It's one of the things I love about you.

You don't need me.

You can handle anything on your own,
because you're fearless.

And independent.

Loving.

Kind.

You are, without question,
the best decision I ever made, Iris West.

And I've never thanked you
for choosing to be with me,

because each day with you is a gift.

So, thank you.

You deserve the world, Iris.

You deserve to be happy
the rest of your life.

And no one wants that more for you
than me.

(SNIFFLING)

Happy birthday, baby.

I love you.

I love you, too.

BARRY: Sometimes,
the only way to move forward

is to revisit the things in your past
that were holding you back.

You have to deal with them, head on,
no matter how scary they may be.

Because once you do, you'll see that
you can go further than you ever imagined.

I'm coming for you.
