The Flash (2014) s04e18 Episode Script

My name is Barry Allen, and I am the fastest man alive.
To the outside world, I'm an ordinary forensic scientist.
But secretly, with the help of my friends at S.
T.
A.
R.
Labs, I fight crime and find other meta-humans like me.
But I became lost in time.
It took everything in my friends' power to bring me back, and in doing so our world was opened up to new threats.
And I'm the only one fast enough to stop them.
I am the Flash.
Previously on "The Flash" So, one more bus meta out there.
Edwin Gauss.
You better find him before DeVoe does.
This is an intelligence booster.
You're talking about intense amounts of dark energy going right into that cap.
I'm gonna help you finish the Thinking Cap, - without using dark matter.
- Fine.
Good evening, Dr.
Wells.
How can I be of service? Hello, Gideon.
Good old CCTA, bus number 405, where I was gifted with pretty much the best powers ever.
If it wasn't for this old girl, I'd still have to leave the couch when I need to use the bathroom, you know, because I can Yes, I know.
All right, this might be our last chance to find any clues on the final bus meta before DeVoe catches him.
Yeah, and we know what happens next.
What do we know about this meta? Other than his name, Edwin Gauss, nothing.
It's like he disappeared.
Well, that explains the brand new, beepy, flashy "schmience" thingies.
Yeah, Cisco designed these scanners to look for dark matter anomalies, so anything that looks weird, all right? Waves, ripples, whatever, log it.
Ho - I got something.
- What? My Big Belly punch card.
I'm only five away from a free kids meal, if I even long enough to use it.
Man, don't even joke like that.
We're gonna get DeVoe, throw him in The Pipeline, long before he gets to you.
Right.
If that doesn't work, we'll just, uh, take him out the other way.
What other way? Eh, we'll put him down with a shovel, give him his harp and wings, send him to visit Grandma Thinker in the sky.
Ralph, you think we're gonna kill DeVoe? The way that you're saying that makes me think I'm supposed to say no.
Okay, look I've taught you a lot about being a hero, right? You ready for what's probably the most important lesson? We never have to kill.
For people with our abilities, there's just always another way.
You understand? Han, you complete me.
- Bring it in, man.
Come on.
- Uh, I'm good.
Just a little bit.
Give me some, come on.
Okay.
What's this? Wait a second I talked to the guy who was sitting there.
I remember, 'cause I paid his fare.
Uh uh-oh.
I think I may have left my wallet in my other pants.
Look, buddy, you either pay the fare or you hit the sidewalk.
Whoa, whoa, whoa! Mr.
bus driver dude, allow me to pay his fare.
Who are we to be the gatekeepers of whatever path this fellow traveler is on? Have a seat.
Uh, thanks.
Oh, namaste, hermano.
Namaste in the back of the bus.
Funny fat dude.
This is crazy.
His residual dark matter reads as if he was here one second, and the next, vanished.
It's Harry.
He wants us back at S.
T.
A.
R.
Labs.
Says he has something important to show everyone.
Well now so do we.
Yeah.
All right, come on.
That's the big news? You're taking a sculpture class at the community college? It's not art.
It's science! And as such it is the thing that is gonna help us defeat DeVoe.
Recall, if you will, the one thing that we've seen nay, heard That can actually harm DeVoe.
Izzy Bowin's soundwave powers.
Well, Izzy was killed by DeVoe, so whatever powers she had is in his hands now.
And now, Joe they're in ours.
Watch this.
So Actually, maybe you should take a couple steps back if you value your internal organs.
I know how that feels.
One strike incapacitates The Thinker.
Two strikes, no more Thinker.
I call it a Sonic Scepter.
Okay.
Points for alliteration.
Basically just a big tuning fork.
My goodness.
Well, like, I mean, it's not just any tuning fork.
This might be the most powerful tuning fork in the multiverse.
You must've laser-shaved this thing - down to the nanometer.
- Shaved it right down to the last angstrom, as a matter of fact.
Child's play for me and my Thinking Cap.
The Sonic Scepter mimics Izzy Bowin's sonic frequencies, so we can penetrate a heretofore impenetrable force field of DeVoe.
And here's the best part.
Because there's no tech involved - It's Kilgore-proof.
Nice.
- Yes.
So, now we just need to figure out where DeVoe is gonna appear next.
As a matter of fact, before you got here I scripted a subroutine on the pocket dimension predictor, and it's gonna give us a massive head start.
DeVoe's next location, thank you.
Yesterday, I thought you said that wasn't possible.
That's right, Snow, I did say that yesterday, but today is a new day.
I've got a million new ideas.
The cap and I, we're Firing on all cylinders.
Onward and upward.
Okay, let's get to it.
Cisco, can you integrate Harry's algorithm - into the predictor? - Can do.
Okay.
Hey Harry's really loving that Thinking Cap, huh? Oh, my God.
It's like the best friend he never had.
I mean, he wears this thing everywhere.
I'm pretty sure I saw him step out of the shower with it.
I want to know what kinda problem he was trying to solve in there.
Nope.
Nope, I I don't wanna know.
- What are you working on? - My brain, or brains.
I think I finally figured out the science behind what activates Killer Frost.
So, in fight-or-flight, the adrenal glands flood the body with catecholamines, uh, AKA the stress hormone, and guess where the highest concentration of dark matter is in my body? - In your adrenal glands.
- Exactly.
So if adrenaline is what activates Killer Frost, - then all I need - Is a shot of epinephrine.
No more Harry and Cisco traumatizing me to get Killer Frost to show up.
I can't wait to tell her.
- Wait, you guys talk now? - Sort of.
Uh, we leave each other notes.
Um "Thanks for the badass new jacket.
"I got some blood on it.
Don't worry, it's not ours.
" I guess her humor is sort of an acquired taste.
Uh-oh.
Pocket dimension's about to open.
It's DeVoe.
Get that pen ready.
Okay, stay ready.
Edwin Gauss? What All right, guys, say hello to our last known bus meta, Edwin Gauss.
As we know, there's not much on him.
No college history, no known addresses.
Just a couple of backpacking photos on an old message board.
Old? Flip phones are old.
This site is from the age of dial up.
Try prehistoric.
No digital fingerprint.
Everything this guy owns is strapped to his back.
He was off-grid before he was even a meta.
That, and his powers are the reason we couldn't find him.
And why there were 12 heat signatures on the bus, including the driver.
Cisco, the way he appeared and disappeared Pocket dimension.
What? Like Like the DeVoe kind? No, like the Edwin Gauss kind.
You see, pocket dimensions, like the one you see here, are unique to their users.
Just like DeVoe can only enter or exit his, Gauss too is limited to his own pocket dimension.
So why does DeVoe need him? Well, DeVoe uses his chair to create pocket dimensions.
If he has Edwin Gauss's powers, he won't need it anymore.
Then we need to catch Gauss first.
And we will.
Little late.
Just tweaking the cap.
Now, listen, locating this meta is not a task that we have to accomplish.
Why is that, Harry? I'll tell you why.
It's because we already have.
Yeah, this is the map that we constructed: Of all the pocket dimension activity throughout Central City.
Right, but that's when we thought all the pocket dimensions belonged to DeVoe.
Now we don't know whether they belong to him or to Gauss.
And figuring out those distinctions, I'm sorry, but that's too big even for your britches, Harry.
My britches are plenty big, okay? I fill my britches.
Watch this, okay? By simply tracking the two lanes of identifiers, cross-referencing the, uh, fluctuation migration patterns and the temporal displacement in the energy app, and I give you Edwin Gauss's pocket dimension activity.
"Ahhh, Harry.
Harry is amazing.
" Yeah, let's all just split up and search each one for Edwin Gauss.
Barry, you take Caitlin and Ralph, and I'll go with Cisco and my dad.
- Harry - I'll go with you.
No, I was thinking that you could just You would stay here and hold down the fort.
Okay, I'll tweak the cap.
Detective, are you Are you not going after Gauss? I'm on my way out.
I just wanted to see if you needed anything before we left.
- If I need no, I'm good.
- Hm.
Holding that Thinking Cap real close.
Well, you never know when you might need it.
Yeah, and you only need it for DeVoe-related problems, right? DeVoe-related problems, science problems, making-the-perfect-omelet problems.
You make omelets with that cap? Oh, yeah.
Pretty darn good omelet.
I bet.
Hey do you mind if I borrow the cap? No, I don't think so.
Not a good idea.
Why not? It seems pretty easy to use.
Detective, this easy-to-use thing is actually a delicate scientific instrument that directly alters the brain wave of the user, - so I don't think so.
- Mm.
- So it's dangerous? - Yeah, it's very dangerous.
And yet you risk using it to make breakfast? All right.
Okay, you're good, Detective.
You're very good.
How much do you wear that cap? I'm not overusing it, if that's what you're asking.
Overusing is one way of putting it.
- Addiction is another.
- I'm not addicted to Your concerns are well-founded.
Ramon had the same concerns.
I told him, promised him I would not use this Thinking Cap with dark matter.
Hm.
And that's a promise you kept? Yes.
All right, I don't mean to be paranoid.
I'm Sometimes, it's just hard to turn off the cop brain.
I get it.
No worries.
Good luck finding Gauss.
Iris where are we? Looks like some sort of hippie commune.
Yeah, smells like one too.
Guys, I think I figured out DeVoe's plan.
He means to suffocate us with BO and incense.
Okay, well, this is the last pocket dimension hotspot on our list, so just Do you see Gauss anywhere? Uh Unwashed flower child, have you seen this man? - Nope - Hm.
I've seen the soul that belongs to this man.
The dude's aura is a trip.
Wait, so, you know Edwin Gauss? Sure do.
'Round here, we call him the folded man.
- Folded man? - He's everywhere and nowhere but mostly, he's around here.
Time for the reflection hike, everyone! Don't forget to leash your spirit animals! Literally already smells better.
Okay, let's just search for Gauss.
Uh, stay in touch over the comms.
Yeah, I will leash my inner-penguin spirit animal and head south.
Be careful.
Don't touch anybody.
Okay, remember, if we find Gauss first, we might be able to put an end to DeVoe's plans.
- Speaking of ending DeVoe - Not what I said.
Allen, I'm just saying, DeVoe's been ahead of us at every turn.
His backup plans have backup plans.
On the off chance that we can't capture him, shouldn't we be willing to do whatever it takes? We know that he is.
I am willing to do whatever it takes, except kill DeVoe.
- Even in self-defense? - It's not self-defense if you're already thinking about it.
Look, I I've been down this road.
I know you're scared.
I understand the temptation, but you have to hear me when I say there's always another way.
I really hope you're right, rookie.
Guys, I got eyes on Gauss! He's fast for a non-speedster! Whoa, whoa, whoa! Easy, narcs.
Hey - I give up.
- We're not cops.
But you are in danger.
We're here to protect you.
Oh righteous.
Is that why you're why you brought your ninja buddy? What? - Caitlin! - Meet us at S.
T.
A.
R.
Labs.
You can't stop me, Mr.
Dibny.
I will cut through all of Team Flash to get what I want.
Are you sure you're okay? Yeah, I mean, the wound started healing before I even woke up.
You frosted out for a sec when we got here.
- It probably helped.
- Yeah.
Hey, uh, shouldn't you rest? Honestly, I'm fine.
If anything, this has just made me more determined to get DeVoe.
I'm gonna go help Cisco with that pocket dimension predictor.
Well, it could've gone worse.
Yeah, all things considered, we got pretty lucky.
- Yeah.
- Lucky? Are you two serious? Am I the only one who's paying any attention here? Ralph, the mission was successful.
Caitlin's okay, and Edwin agreed to stay in The Pipeline.
- Edwin will be safe in there.
- Safe? Because DeVoe's never successfully attacked metas in a maximum security facility before.
Oh, wait, he did exactly that.
- Watch it, Ralph.
- I have been watching.
Watching DeVoe ahead of us at every turn, watching Caitlin get skewered, watching the metas drop like flies, one by one, because we can't save them.
And why? Because we won't make the tough call and end DeVoe when we get the chance.
Look, I'm not doing this again.
Okay, Ralph, I get where you're coming from, but that is not the tough call, that is the wrong one.
Oh, Mr.
and Mrs.
S.
T.
A.
R.
Labs agree.
I swear if I was running this team - But you're not.
- Okay, all right.
That's enough.
We don't have time for this, okay? We need to focus and stick to the game plan.
Find DeVoe, hit him with the scepter, and put him in The Pipeline.
No one has to die.
Huh same plan again.
And you wonder why he's always ahead of us.
Yo Magnum PI.
I am digging this tiny panic room, bro.
It's it's it's like Like an eggshell for my body which is the eggshell for my soul which contains the universal myste Zesty Ranch.
Right on.
You strike me as a munchies kinda guy.
Guilty.
Oh, wait, wait, wait, not actually guilty.
It's not like I'm on anything, you know? You you you guys said you aren't cops, right? - Nope.
- All right.
But apparently we have to follow more rules than they do.
Well, whatever rules protect me from that evil genius dude, I shall heed.
Even his name is creepy.
"The Ponderer.
" It's, uh, Thinker.
Yeah, sure is a thinker.
Makes me think about my journey.
Like, first time I folded, I was in this white space for, like, days, and then another time, I tumbled down this ramp in this space agey room with blue lights, and there was this bald dude in a Professor X floaty chair, with tubes coming out of his noggin, and there was this this lady in a white lab coat, with such a hot accent.
Ah Wait, wait, wait, Edwin, do you remember anything else from there? Anything at all? This is important.
Well, I don't know if this detail is relevant, but, um, they had one of those robot samurai dudes.
You were in DeVoe's lair.
Wait, how can that be? Cisco said that a pocket dimension can only be accessed by its specific user.
I mean You know, some places are harder to get to than others, but if you ascend your mind to a high enough plane You can go anywhere.
And my mind is really high.
Edwin, can you get us back there? "Fa sho.
" - Come on.
- What? I I I got more.
No, I I got more, I got more.
I cannot do it any faster, Captain! If I apply anymore hobby glue, this ship is gonna blow! Wow.
This glue's really something else.
I should probably wear a respirator.
Where is it? Where's what? The exit? It's right behind you, please and thank you.
I can't find my Thinking Cap.
I hey, I don't have it, Captain Caveman! I never said you did, so why would you volunteer that information unless you do have it? - Get out.
- I know what this is about.
You never wanted me to build this sucker in the first place, 'cause you never wanted me to be smarter than you.
Well, guess what, that's funny, 'cause I already am.
What the hell are you talking about? I want you to - What the hell are you doing? - Give me my cap! - Hey! What? - Give me my cap! Give it to me.
It's mine.
It's my cap.
- Cut it out! - It's mine! Harry! He didn't take it.
I didn't take it.
You definitely have a problem, man.
- Joe, this is fine.
- No, uh, be quiet.
Just listen.
I've seen these signs before with my late wife, Francine.
Back then, I didn't intervene so quickly, because I said to myself, I needed to be sure.
But I was sure.
I just didn't wanna see those signs in somebody I cared about.
I can't make you stop using this.
That's up to you.
All I will ask is that you take a long, hard look at what it's doing to you, and how it's making you treat people you care about.
Ramon Uh where are we going again? You're gonna open up a pocket dimension into DeVoe's lair, and I'm gonna stop him for good.
No, you're not.
Cisco installed motion detectors in The Pipeline intake.
I thought it was DeVoe coming for Edwin.
Now I kinda wish it was.
Edwin can get me into DeVoe's lair.
I can end this.
All you have to do is let me go.
- I can't let you do that.
- Um Um, listen, I I don't really do confrontations, so, uh, can I just go back to my glass cage? We're both leaving in a second.
Okay.
Just give me the scepter.
You know I can take it away from you if I have to.
Yeah? Well, you're gonna have to take it out of me.
- Oh - Whoa, bro.
Wow, okay, I'm actually glad I stayed for that.
That was trippy.
- Don't do this? - Do what? This? I'm sorry, Ralph.
Olive Branch? You don't wanna have a drink with your buddy? Is that what you call someone who just went all "Thor, son of Odin" on you? You can take it.
Yeah.
Look I know you're worried about DeVoe, about what he might do to you, but there are some lines we can't cross.
Wow You really don't know as much as you think you do, rookie.
I know what killing DeVoe would do to you.
You would be throwing away everything you've done: to become a better man, to become a hero.
You gotta realize that.
You are a moron.
- Ralph - I am not afraid of DeVoe and what he might do to me.
I am afraid of what he might do to you and Iris and Caitlin and Cisco, Joe, Harry, Cecile.
DeVoe has taken out everyone who's gotten in his way, and Team Flash they will always be in his way.
This was never about protecting yourself.
I know that killing DeVoe would mean throwing away everything I've done to become a hero But aside from my mom, this team is the only family that I have ever had, and I would throw myself into a furnace to keep them safe.
DeVoe cannot have them.
They are mine.
What about what we want? You may not care about losing who you've become, but we do.
We like hero Ralph.
Please don't take him away from us.
Well, Ralph was misguided, but he had a half-good idea.
- Which half? - We use Edwin Gauss's powers to create a pocket dimension to DeVoe's lair.
Yep, that's the half I was afraid of.
It doesn't get more dangerous than this, so if we go, everybody needs to sign off.
Look, you two have led this team through every danger there is, so if you think this will stop DeVoe from claiming any more lives, then let's go get that bastard.
I mean, damn, Joe, when you put it all John McClane like that, of course I'm in.
I'm in.
I don't even need to ask Killer Frost what she votes.
- We're in too.
- So it's settled.
Tonight, we take on The Thinker.
Open it.
You got it, mega-fast dude.
Open it again in 15 minutes.
If we don't come out with DeVoe in cuffs, close it.
Don't open it again.
- It didn't work.
- Why would it? Sound has no effect on a hologram.
If DeVoe's not here, then Now, my love the real battle begins.
What's happening? Someone's taken over our systems and sealed us in.
A second pocket dimension opened in S.
T.
A.
R.
Labs at the exact same time as ours.
It's DeVoe.
He used that first opening to conceal his own entrance.
That's why our sensors didn't register.
This is all a part of his plan: the Samuroid attack, us getting Edwin, using him to attack DeVoe's lair.
- He wanted us divided.
- Where did Edwin go? He's back locked in his cell, and we got DeVoe's pocket dimension energy coming from the Cortex.
That must be where his chair is.
I mean, if we can get to it, we can use it to get our team back.
First, we gotta get ourselves out of here.
- Harry, can you unhack his code? - Trying, but it's too complex.
If I had my quantum decryption keys, I could do it, but they're stuck in Cisco's workshop.
But we're not stuck in here.
What are you gonna do? It's a little worst-case scenario that I had Cisco whip up.
Get back.
Get back.
Harry, go get your equipment I'll go and hack the computers.
Yeah.
Iris, get to that chair.
- Dad, you can't - Go.
Ah! I heard all the commotion, and I thought, "If DeVoe was here, where would he be going?" Hmm.
A simple deduction for a simple man.
Though I assure you, you are no threat for an intellect of my magnitude.
Please.
Everyone I fight is smarter than me, but no bad guy has beaten me yet.
Well, I'm afraid an old friend requests a rematch.
I really hate sequels.
Ah Mrs.
West Allen, I was hoping we'd meet again.
You might change your mind about that pretty soon.
Ah there's that passion from our chat in the courthouse.
But I do remember warning you that it could easily be destroyed.
And I remember you asking me what I was willing to do for my husband.
How about I show you? - Gideon? - Yes, Dr.
Wells? Increase the Thinking Cap's dark matter feed.
More.
Warning: Safe zone parameters will be exceeded.
- Recommended - Maximum capacity now! Come on.
Little closer.
Little closer.
Warning: Fists in Pipeline are larger than they appear.
No.
Even gray matter as unevolved as yours understands the pain of psychic attacks.
You were born for me, Mr.
Dibny, and now you will die for me.
You first! What's that? A big old fork to shove up your One more strike and you're dead.
I have been waiting for this a long time, you and me alone, so I can make the hard choice that no one else will.
Ah! Ah! Perhaps you are willing to do what it takes But it seems my love is stronger than yours.
Get out of my office.
Where is he? - Iris? - I'm okay.
I'm okay.
The others are still out there fighting DeVoe and a Samuroid.
Actually, now it's just DeVoe.
- Hm.
- Iris? I'm okay, we just need to get DeVoe.
Breach us to him.
I'm ready to get blood on this jacket.
That blow back in the lair knocked down my breaching.
- I'll find him.
- Mm-hmm.
Did you just Beat The Thinker? Yeah, I did.
You just got out-thunk, punk.
And I see you went with the same plan, as always.
Eh.
Do you remember when I visited you in prison? You said that I could have a greater life if I'd just rise up.
Well I'm ready for that life.
And for the first time, I might even deserve it.
Yes it appears I have been bested.
However a tip, if I may.
Before you cuff a meta, make sure the light is the right color.
Ralph! Ms.
Betty never understood the full magnitude of her powers.
You're currently the same gravimetric weight as a cement truck, Mr.
Allen.
That should hold you long enough to bear witness.
Ralph! Just fight it, all right? Fight it! I'll save you.
You already did, Barry.
No no No! - Ralph? - God Stand back.
Melt.
All the training, all the lessons you taught Mr.
Dibny to help him reach his full potential, this body will be the greatest gift of all.
Thank you, Mr.
Allen.
You were an excellent teacher.
We were supposed to save them.
We tried.
We failed.
I know this isn't the ending we were expecting, so If anyone wants to talk Should I track him down? No.
I think I know where he's going.
- Cisco? - Hey.
Uh, weather says rain's coming.
Do you mind helping me? Can you get Harry? I think something's wrong with me.
Well, your vitals seem okay.
Blood pressure, respiratory rate seems normal as well.
You're gonna have to run the test again.
There was some feeling.
I I don't know what it was, but You touched DeVoe.
Hand me the dark matter scanner.
The dark matter scanner I'll get it.
- Focus, Harry.
- Yeah, focus.
There's no trace of dark matter anywhere on your body.
He must've used Melting Point's powers to entangle your meta DNA.
- So, Killer Frost - Is gone.
Thought I might find you at the other office.
Yeah, well, without Ralph being around to dodge rain, it's only a matter of time before the landlord closes this place up.
I know there's some things in here Ralph wouldn't want anybody finding.
You know you could just whoosh around and you could pack up a lot faster.
Yeah, I know.
- Barry, look, I just wanted - Iris, I I know that you're You're here for me and that I can talk to you, and I love you for that, but right now, I just need to pack up.
That's all.
Okay, yeah.
Um I'll leave you to it.
I'll keep them safe.
To our overwhelming success.
Yes, in more ways than one.
- What do you mean? - Not only is my new host body immune to the ravages of my ever-expanding mind It also holds an ancillary benefit.
Clifford.
I'm nothing without you And now, all of me is with you once more.
But we must temper our celebration with conviction.
Our plans have yet to reach their apex.
- Is that - Dark matter.
Siphoned from the room where Dr.
Wells was charging his counterfeit cap.
As I predicted, his hubris was his undoing.
And so, now, the fire that burns down Team Flash Will also light the path to the Enlightenment.
