The Flash (2014–…): Season 1, Episode 23 - Fast Enough - full transcript

With the Particle Accelerator back online, Barry can go back in time to stop Eobard Thawne on the night of his mother's murder fifteen years ago.

My name is Barry Allen,
and I am the fastest man alive.

When I was a child, I saw my mother killed

by something impossible.

My father went to prison for her murder.

Then an accident made me the impossible.

To the outside world, I am
an ordinary forensic scientist,

but secretly, I use my speed to fight crime

and find others like me.

And one day, I'll find who killed my mother

and get justice for my father.

That day is today.

What? No Big Belly Burger?

It's one of the few perks
of living in this time.

We're out of cows where I come from.

You don't care about that.
You have questions. Go ahead.

Not sure where to start... Thawne.

That is your real name... Eobard Thawne.

- Since the day I was born.
- And when was that?

136 years from now.

That's not what you want to know.

Go ahead, Barry.

Ask it.

Why did you kill my mother?

Because I hate you.

Not you now. You years from now.

- In the future.
- In a future. Yes.

We're enemies, rivals, opposites,

reverses of one another.

Why? Wh-why were we enemies?

It doesn't matter.

It doesn't... matter anymore.

What matters is that
neither of us was strong enough

to defeat the other.

Until I learned your secret.

I learned your name.

Barry Allen.

And finally, I knew how
to defeat you once and for all.

Travel back in time, kill you as a child.

Wipe you from the face of the earth.

But then you, future you,
that is, followed me back,

and we fought.

We both landed some pretty solid shots.

And then you, future you, got
your younger self out of there.

I was so mad.

But then I thought...

what if you were to suffer a tragedy?

What if you were to suffer
something so horrible,

so traumatic that your child
self could never recover?

Then you would not become The Flash.

And so I stabbed your mother in the heart,

and I was free.

Finally able to return
to a future without The Flash,

only to realize that in traveling back

I'd lost my way home.

Lost my ability to harness the speed force.

And without it, I was stuck here.

Stranded in this time,
unable to return to my own.

And the only way back was The Flash.

But The Flash was gone,
and so I created him.

Why train me?

Why help me save so many people?

Because I needed you to get fast.

Fast enough to rupture
the space-time barrier

and create a stable wormhole

through which I could return home.

Why would I ever do that?


Barry Allen, if you give me what I want,

I'm gonna give you what you want.

You can go back and save your mother.

You can prevent your father
from going to prison.

You can reunite the Allen family.


No, I don't believe you.

I want to kill you right now.

I know that rage.

I used to feel that rage
every time I looked upon you.

And now, somehow,

I know what Joe and Henry feel

when they look on you with pride.

With love.

No. No.

Don't you ever say that to me!

I know you're upset,

but I'm giving you a chance.

I'm giving you a chance to undo
all the evil I've done.

Don't you want that chance?

The rare opportunity to go
back in time and right a wrong

and save your mother's life...

quite the paradox Harrison has
presented you with, Mr. Allen.

The chance to be with someone you love?

Seems pretty cut and dry to me.

(Stein) At first blush,
Dr. Snow, it would appear so,

but this gift has unparalleled risk.

Barry, the night your mother died,

the night you saved yourself
from being killed,

that event altered the timeline
you were already on

and changed the course of history.

So what you're saying is we're
living in a parallel universe?

Just like when I time traveled before.

But he... he only changed one day that time.

Exactly. Now imagine 15 years
of compounded experiences.

One different decision,
no matter how big or small,

impacts everything that follows.

Moments upon moments, choices upon choices.

No relationships,
nothing would be as it is today,

and you'd never know the difference

because you'd never remember any of it.

So if I go back and save my mom,

my dad doesn't go to prison.

I never live with Joe and Iris.

You might never meet me.
Or Caitlin or Ronnie.

Truth is, there's no real way

of knowing what your life will be.

There's no choice here, Barry.
You have to do this.

You gotta change the past.


So what... what, that's it?

You think I should just do it?

Yeah, I do.

Which means I will never
come to live with you, and...

you're okay with that?

Barry, you get the chance
to grow up with both parents.

You don't have to grow up without a mother.

What about growing up without a father?

You will have a father... your real father.

Wells has messed with our lives
long enough.

This is why you became The Flash, Barry.

To put things right.

You saved a lot of
people's lives this past year.

Now it's time to save yours.

(Barry) Dad, look. I
know this sounds crazy.

I think we're way past crazy, slugger.

Look, you're fast, I get it.
But turning back time...

No, I wouldn't be turning time back.

I would be... going back

to that night to save her.

And what does Joe think about all this?


He thinks I should do it.


You can't.


I can make it so that night
will never have happened.

We'll be a family again.

We are a family.

Not like this. Not without Mom.

Barry, there's a natural order
to things, okay?

Things happen the way they do.

We may not know why at the time,

but there must always be a reason.

Now, I believe that.
I've had to believe it.

I... I can save Mom.

At what cost?

You said time would change.
What if it changes you?

- I don't care.
- I do.

I am in awe

of the remarkable man
that you are becoming...

all the things you've achieved,
and not just as The Flash,

but you, Barry.

Your honesty. Your heart.

You were always a hero.

And your mom would be just as proud.

And if she had a say in this,

if she thought for one second
that you going back to save her

would mean you losing
what makes you so special,

she would never want that.


Barry, what I hope for you,

maybe the greatest thing that
a father can hope for his son

is that one day, you will become
a father yourself.

And then you will know...

How much I truly love you.

[thermometer beeps]

(Caitlin) 98.6. Normal.

I don't even know
what that word means anymore.

Me neither.

I know Barry really appreciates you

coming back to help him stop Wells.

That's not the only reason I'm back, Cait.

I'm here now. For good.

But I thought...

I thought too... I thought too much

about what might happen if
the government tracked us down.

If we couldn't control
our powers and we hurt someone.

If we hurt you.

But I realized that although
sometimes I'm more than one man,

I'm not whole unless I'm with you.

I love you, Cait.

- Are you sure?
- I am.

Once upon a time and a
Particle Accelerator or so ago,

you agreed to marry me.

Yes, I did.

What do you say we do that?

Thought I might find you here.

I needed to get out of the lab.


I thought this would be
a good place to think.

Oh, it is. Trust me.

I've done a lot of thinking up here.

When I wasn't having clandestine meetings

with the mysterious "streak."

[both chuckle]

Yeah, not mad we lost that name.

Hey, I thought that had pizzazz.

[both laugh]

- No.
- Uh-uh.

[gentle music]

So are you gonna do it?

It's just so... huge.

It's the biggest decision of my life,

and if I'm wrong, I can't undo it.

Why would you want to?

I mean, you'd get to see
your mom again, your dad,

have a great career,

even get married.

Iris West-Allen, huh?

I never really thought of myself
as a hyphenator.

Must be a 2024 thing. [chuckles]

We don't know that that's gonna happen.

Do you think that because you
didn't live with us,

that's why things are different there?

Growing up together and...

knowing so much about each other...

it made it hard for me to admit
how I felt about you.

And I waited too long, and you
fell in love with Eddie.

But living with you and Joe...

I've had a great life, Iris.

Come here, Barry.

What do you think I should do?

I need someone to tell me.

I think...

that for once in your life, Barry Allen,

you should stop thinking
about other people.

I think you should do what's in your heart.

Do what you need to do for yourself.

(Wells) Ah!

Well, if it makes you feel any better,

it took you a whole hour longer to decide

than I thought it would.

So how does this work?

Your grand plan?

Well, it's really not
that grand at all, Barry.

In fact, it's rather simple.

We use the Particle Accelerator.

[laughs] The Particle Accelerator.

The last time that happened,
you caused an explosion

that hurt a lot of people.

This time, the accelerator
will operate exactly

the way it was designed to.

Except, instead of two particles
moving in opposite directions,

colliding at the speed of light
in the inner ring,

we're only going to inject one particle

into the accelerator.

And I'm what it collides with.

And if you can go fast enough, Barry,

if you can hit that particle
with enough speed,

you will punch a hole right
though the fabric of reality.

And you will create a portal
connecting this time

to infinite times.

A wormhole.

Through which one might travel
back to the past, say,

to the night your mother died or
forward to the future, to, say,

my time.

You said if I run fast enough.

What happens if I don't?

If you don't achieve
the desired velocity, Barry,

you'll die.

According to Wells' calculations,

Barry super-speeds
inside the accelerator ring.

Once Barry reaches optimum speed,

we then launch a hydrogen proton
into the accelerator.

Once the collision happens,
a wormhole forms,

opening a gateway into time itself.

It's at that moment
I plan on shouting something

along the lines of "Eureka"
or possibly "Excelsior."

I'm uncommitted.

What do you think?

[sighs] I mean, on the one hand,

it does make a kind of sense.

On the other hand,


Why, why would you ever
consider doing this?

You know why.

So, for this to actually work,
how fast would Barry have to go?

By my estimates, Mach Two at a minimum.

You've never gone that fast.

So what happens if Barry
doesn't reach that speed?

I mean, I'm imagining a bug
hitting a windshield.

How far off am I?

Not very far, I'm afraid.

Let me worry about how fast I have to go.

We're gonna need something else too.

Really? And what's that?

'Cause I don't know about you guys,

but I'm not at all interested in
helping you get yourself killed.

I need you to build a time machine.

Go on.

So, if Wells is as fast as you,

what's he need a time machine for?

Apparently he lost his speed
when he killed my mom.

He gets it back sometimes
but only in spurts.

He can't fully control it.

So I was right about the wheelchair.

He was using it to charge himself.

So after I open the wormhole,
he's gonna need the ship

to travel back to the future.

He's been squirreling away the parts.

Now we just need to put it together.

Ronnie, I love you,
but this is a time machine,

not a bookcase from IKEA.

We got a problem.

These tiles... they're made of tungsten.

Well, tungsten does have
the highest melting point

of any other element.

Yeah, but the dust
it generates is flammable.

The pressure exerted from the wormhole...

Yeah. Yeah.

It could cause a hole to be
melted into the exterior.

It could explode.

Any ideas?

Let me ask Dr. Evil. [chuckles]

Which used to be a name that made me smile.

(Wells) Something on your mind, Cisco?



How did you fit your Reverse-Flash suit

into that little ring?

Is it some sort of compressed micro tech?

Or actually, forget it. I don't care.

Maybe a little.

Ronnie's right.

I should have accounted
for the temporal shearing.

Glad we're still good for something.

I never underestimated
your contribution, Cisco.

Or Ronnie's.

Matter of fact,

do you know how many times
I wished you were there with me

as I rebuilt the accelerator?

It would have been a lot more fun.


Well, doesn't change the fact

that your nifty little Time Sphere...

Is that what you're calling it?

Whatever it's called. It's gonna blow.

Not if you cement the tiles
with a cobalt resin.

That'll prevent degradation
in conditions of extreme heat.

Okay. Fine. We'll try that.

(Wells) That's it? That's all?

Well, what do you want me to say?

I don't know, Cisco.

I thought that of anyone, you'd
be a little more understanding

of my predicament.

I don't belong here.

These barbaric times.

It's like living amongst the dead.

Is that what you told yourself?
When you killed me?


What did you say?

It was an alternate timeline.

One that Barry reset.

But I never forgot it.

It just kept coming back to me.

And I can still picture

the way you looked at me

when you called me a son

and you crushed my heart with your fist.


I'm sorry.

Yeah. It sucked.

Not for killing you.
I'm sure I had a good reason.

I'm sorry for the fact that
you're able to retain traces

of another timeline.

You're able to see through
the vibrations of the universe.

It means...

I wasn't sure until just now.

Sure of what?

The night the Particle
Accelerator exploded...

You were affected too.

What are you talking about?


I wasn't.

Don't be afraid, Cisco.

A great and honorable destiny
awaits you now.

I only hope that as you're
living your great adventure,

that you remember who gave you that life.

And that it was given out of love.

[ominous music]

I'm sorry, but I'm told
this is the only station

with enough power
to run these calculations.

If we make the slightest error
creating the wormhole...

Say no more.

Joe told me to stick around
in case I was needed,

but it seems I'm only in the way.

Everyone has a contribution to make.

Perhaps you just haven't
discovered yours yet.

No, Dr. Wells made it
pretty clear when he told me

about the future.

I don't matter.

As far as history's concerned,

I don't save the day or get the girl.

And you believed him?

He had a newspaper from the year 2024.

And I have a mug that says
"World's Best Boss."

I doubt my teaching assistant would testify

to its authenticity.

We're dealing with a lot
of big scientific ideas today.

But you, Mr. Thawne, might be
the most interesting thing here

at S.T.A.R. Labs.


What are the odds that Dr. Wells
would travel back in time

and get stuck in the exact same city

as his great-great-great-

Working in the same profession,
the same building?

And that part of his plan
to get home would mean

that he'd have to preserve
and protect your life.

That makes you this rare thing
that no scientist can plan for.

Which is?


There is no science to coincidence.

You, sir, are an anomaly.

A wild card, as it were.

You are the only person in this whole story

who gets to choose his own future.

At least, that's my opinion.

[computer blips]

Wait, that can't be right.

Oh, dear.

- We have a problem.
- What?

(Stein) The calculations.
There is a danger.

I know. I'm ready to take the risk.

No, not just to you but to everyone.

Wells didn't tell us everything.

Barry, even if you do reach
the right speed,

colliding with the hydrogen particle,

there is a chance that explosion
could create a singularity.

What's a singularity?

It's a black hole.

We could destroy Central City.

For starters.

If we create a singularity here
and then cannot control it,

we could be looking
at a global catastrophe.

So long and thanks for all the fish.

(Wells) Well, sure,
there's a bit of a risk.

(Stein) I would hardly
refer to possibly causing

an extinction-level event as
"a bit of a risk."

(West) Yeah, and your accelerator's

been about as reliable as the
beater I drove in high school.


Let me ask you a question.

How many meta-humans...

how many dangers...

have we faced this year together?

Or did you forget that was me

fighting alongside
each and every one of you?

I have been planning this
for almost two decades.

It will work.

And how do we make sure
we don't open a black hole

in the middle of Central City?

So, once the wormhole stabilizes,

Barry will have 1 minute
and 52 seconds to alter the past

and return to this time.

If and when he does that,

you can close the wormhole,

and we can all live happily ever after.

Almost two minutes.

More than enough time to save Nora.

But not enough time
to stop you from going home?

Everything's a choice.

And what if I'm late?

You won't be. I believe in you, Barry.

Always have.

So I guess the question is,

do your friends and family
believe in you as much as I do?



So, if I don't run fast enough
to collide with the particle,

then I'm dust, and if I do run fast enough

but I'm not back here in time,
then a black hole will form,

swallow up the city and possibly the world.

You're sure you still want to
look me in the eyes and tell me

this is for the best?

I'd be lying if I told you I did.


Truth is, I don't...
I don't know what to think.

I thought you were the sure one.


was kind of banking on that
when I made my decision

the first time.

I was faking it.

Sometimes parents do that.

Most of the time, parents do that.

Look, of course I'm scared.

But I didn't want you to not
help your mother

because you were worried about me.

Well, I'll always worry about you, Joe,

just like you'll always worry about me.

Sorry, but you can't stop that.


Do you think I can do this?

You think I can save my mom?

I mean, do you think I'm fast enough?


I know you are.

You know, I've... I've dreamed
my whole life about...

saving her,

freeing my dad, and...

I never thought I'd have to lose
another parent to do that.


Joe, it's true. It's true.

I've always been so focused on everything

that I lost that night,
but I gained so much too.

I was born with one father,
and that tragedy gave me...


And I don't think I can lose you.

You won't ever lose me.

Ever, you hear me?


Wow, slow news day?

If they only knew, right?

I thought you would be at S.T.A.R. Labs.

I was.

Then I got hungry, so I went to Mama Chows.

For dim sum? Your favorite.

And to remind myself of something.


A coincidence. A pretty big
coincidence, actually.

About a year and a half ago,
I had a date with this girl.

Katie Rogers. She was a dancer.

We had plans to meet at Mama Chows,

but she texted me.

She pulled a hamstring and had to cancel.

Oh, those fragile dancers.

I was bummed 'cause I was
looking forward to it.

So I had dinner by myself,
and I was walking home

when I saw a mugger
running with a stolen backpack.

Your backpack.

And I arrested him.

That's how you and I met.

I remember.

Someone just told me how
powerful a coincidence can be,

and it made me realize how many
coincidences had to happen

for you and I to get together...

in this time.

We've all been so focused on
Barry's destiny,

I forgot that I have one too.

And it's you.

Iris West,

every moment of my life led to meeting you.

Screw the future.


Screw the future.

[pop music]

(Ronnie) Is this actually binding?

(Stein) My father made me become a
rabbi before he would send me to MIT.

This will be "legit," as the kids say.

No kids say that.

Let's not fight on our wedding day.

I'd like to skip all the Hebrew.


I've learned a lot

about merging one's life
with another this past year.

Yet, for all the incredible
advancements in science

we've all been party to,

the mystery that brings
two people together through love

is still the province of magic.

There are gonna be three yous back there...

the you from the future

who saved younger you
from the Reverse-Flash

and now you you.

Remember, wait until future you
gets younger you out of there,

and then you can go and save your mom.

Piece of cake.

May the Speed Force be with you.

Good-bye, Dad.

Good-bye, Son.


You don't have to say anything.

I already know.

I hope whatever life you get,
it's enough for you.

That it makes you happy.

You too.

(Stein) Remember, Mr. Allen,

assuming you achieve the proper
velocity and open the wormhole,

you will only have 1 minute and 52 seconds

to save your mother and return.

Or else...

(Flash) I know.


you hold both our futures
in your hands now, Mr. Allen.

And I know you can do it.





[heroic music]

The accelerator's structural
integrity is holding.

What was that?

Is Barry okay?

Yeah. He just passed Mach Two.

(Iris) I was waiting for
you to bring Barry home.

Looks like he's going to be
staying with us for a while.

(Wells) Barry, what you're
seeing is the Speed Force:

your past, you present, your future

all at once.

So you need to focus
on where you want to go.

So think about...

that night.

Think about your mother.

(Henry) Time for bed. Good night, slugger.

(young Barry) Mom!

[Nora and young Barry shouting]

It's working.

It's working.

Inject the hydrogen particle now.

What's that? What happened?

Barry... he's gone.

- Look.
- The wormhole.

And it's stable. Start the clock.


[ethereal music]

(young Barry) Mom!





Nora! Hold on!

[slow motion] Run, Barry, run!

Barry, no!

No, no, no!

- [knife pierces flesh]
- [Nora screams]



[Nora whimpering]

Hey. It's okay. It's okay. You're okay.

Please. My husband, my son, are they...

They're okay.

They're both safe.

I promise.

Who are you?


I'm The Flash.

I don't understand.

You look just like my father.

This won't make any sense,

but it's me, Mom.

[laughs softly]

It's Barry.


Your Barry.

Oh, my beautiful boy.


I got a second chance

to come back here and...

Tell you that I'm okay.

Dad and I are both okay.

And we love you, Mom.

I love you.

I love you.

Oh, my sweet boy.

Bye. Good-bye.

Good-bye, Barry.




[clock beeping]

I believe it's time to
say good-bye to Harrison Wells.

It's beautiful.

Rip Hunter would be impressed.

He built the first one of these.

Interesting man.

Now what the hell is that?

That's my cue to leave.

Thank you, Cisco.

Don't ever come back.

[exciting music]

30 seconds.


- Oh, my God.
- Barry.

We have to shut down the wormhole quickly!



(Wells) You didn't save her.


[shouts] Why?

You could have had the life you wanted.

You could have had
everything you ever wanted!

I already do.

Not for long.

(Caitlin) Cut the internal generators.

(Stein) Ten seconds, hurry.



Three, two, one.

Ronnie, are you okay?

[grunts] Did you do it?

Yes, I turned them all off.

They did it. They cut the generator.


Just so we're clear,

after I kill you,

I'm going to kill them.

And then I'm going to kill your father.

I always win, Flash.


[screams] Eddie! Oh, my...

(West) Eddie!

What did you do?

What did you do? What did you do?

No such thing as a coincidence.

What's happening?

Cisco, help me.

Eddie's his ancestor.

If Eddie dies, he'll never be born, and...

He's being erased from existence.

No! No! Eddie.

Eddie, no, no.

Stay with me, okay? Stay.


He was wrong, it turns out.

I'm a hero after all.

You are, Eddie. You are my hero.

That's all I ever wanted to be.

Your hero.



[Iris cries]

I've controlled your life
for so long, Barry.

How will you get along without me?


Guys, that's not good.

Professor, I shut down the wormhole.

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

You did close it,
but it seems to be reopening.

We got to go.

You okay?

Iris, we have to go.

I'm not leaving him.

We have to go now, honey. I'm sorry.

So that's what we didn't want to happen.

- What's it doing?
- Feeding.

The singularity won't stop, not
even after the Earth is gone.

- [tires screech]
- [people screaming]

I'm afraid the accretion disc
has already assembled.


Diffuse material

that's in orbital motion
around the singularity.

What does that mean?

We have to disrupt the motion.

Basically it's just like
the tornado, only upside down.

And bigger.

And scarier.

Barry, that event has an energy level

of at least 6.7 Tera Electron Volts.

It cannot be stopped.

I have to try.

[dramatic choral music]

Oh, God.


[heroic music]
