After killing Alexa, “Nora” vows to kill Psych and Deon. Barry wants to travel back in time to remove their connections to the Forces, but Iris and Cisco disagree. Cisco gives Kamilla a camera that can detect the forces, which later shows a connection between Iris and the forces, so Iris, Allegra, and Kamilla use that to track down “Nora.” Barry, Cisco, and Chester work on the tachyon device so that it can extract the Forces’ particles, and Barry retrieves Harrison Wells from Starling City in 2000 for help, who can create a “time bubble” to protect the timeline from Barry’s interference. Deon arrives at S.T.A.R. Labs and realizes that Barry will take away who he is and ruins the tachyon device. Iris searches for “Nora” at Barry’s old house, but is ambushed by Psych, who gives her nightmares of “Nora.” Chester fixes the tachyon device while Joe tries to dissuade Barry from his plan of action, but Barry and Wells go back in time regardless. Barry’s interference revives Alexa and erases Psych and Deon in the present day (allowing Iris to escape), but Barry ultimately releases the particles, reverting the changes. Caitlin notices Alexa’s revival, and Barry and Iris use their connection to the Forces to revive her. Cisco and Kamilla realize they need to leave Central City, and elsewhere, “Nora” attacks Deon.
* * *
You killed Alexa.
Nora: Barry and I did it together.
That was the only way.
She was the strongest.
I needed every ounce of power, including your strength, to kill her.
I’m supposed to protect lives, not destroy them!
I’m helping you clean up your mess, Barry.
This is your fault.
The night you brought me back, you created these monsters.
You and your lightning rod.
When you regained your speed, I wasn’t the only thing you two willed into existence.
Alexa was afraid to come here, but she trusted you.
Because deep down, she could feel a connection with you.
The same connection that you feel with me now.
But, these new forces?
The way they’ve merged with the people they chose as avatars?
It’s corrupted them because it’s unnatural.
But once the other two are gone…
I won’t help you kill again.
My beautiful boy. You have no choice. Because if you don’t, those things will kill everyone you’ve sworn to keep safe. Is that what you want? Then, please, Barry help me.
You have to help me, damn it!
I will destroy those other forces, Barry, with or without your help. Then you’ll see that I’m right.
[scoffs] What a day.
First, Frost is sent to Iron Heights for life, and now Alexa’s dead.
I can’t let this happen again.
I’ll get to work.
I need to figure out how Nora was able to…
Kill a god?
She could because she had help.
Barry, she tricked you.
No, she manipulated me, just like she’s been doing the whole time.
Honey, I know how you feel, but not everything she did and said was a lie.
I mean, there were moments that felt real too.
That must mean…
Iris, we can’t trust her anymore.
What about what Nora said about you two creating the other forces?
I mean, there’s no proof.
Well, what if we find out if Nora’s telling the truth?
If she is, then that means the other forces would have been born the same day she was.
I’ll pull satellite scans from the night we fought Mirror Monarch.
Please, and thank you.
Okay, you see that cluster of kinetic energy readings?
Pretty sure that’s the Speed Force being reborn in the Speed Lab.
Whoa. There they are.
Three brand-spanking-new isotopic signatures.
Nora was right.
We created the forces.
Nora killed her.
She killed the Strength Force?
And now she wants to kill the other two forces.
Maybe I should go to San Francisco.
My series of photos on Eva’s attacks got accepted at a gallery there.
[laughs] Well, I was thinking of going to help them install the exhibition.
I’d ask you to come, but I know you have your perfect job at S.T.A.R. Labs and your amazing friends.
I mean… you’re an OG member of Team Flash.
Yeah, I’m fine.
This is an isotopic scanning lens.
It can detect the signatures of all four forces, even kinetic signatures from Speed Force Nora.
And if one’s nearby…
It lights up like an overexposed landscape.
In which case, you run the other way.
Okay? I’m serious.
I just want you to be safe.
Are you sure you’re okay?
Ohh, it’s Barry.
I gotta get back… they could have found Nora, or worse, she’s come back on her own.
How bad is it?
Okay… did Nora kill somebody else?
No, and I have a way to make sure she never does.
What’s going on?
I spent all night coming up with a way to fix all this.
Okay, what’s the solve?
We need to wipe the new forces out of existence.
Barry, what are you saying?
I want to go back in time… and uncreate them.
Barry, you’re talking about creating another Flashpoint.
You know we can’t do that.
Not if I can figure out a way to go back that doesn’t affect the timeline.
Which would be impossible.
I know that you’re devastated about Alexa.
But uncreating forces?
That crosses a line.
I convinced Alexa to come here.
Her death is my fault.
If we don’t get these new forces out of Psych and Deon, Nora will kill them, too, so it’s on us to fix this.
By killing Deon and Psych?
No, I’m not killing them.
I’m saving them from the forces that took over their lives.
Whoever they were before this, they can go back to being those same people again.
And what about the other force that was born that night?
Nora. If you uncreate her…
We’re only gonna target the new forces, not Nora. That’s the plan.
But if something goes wrong, Barry, you might lose your speed.
Then I lose my speed.
It’s… it’s worth the risk to keep everyone safe.
And what about the risk to Nora?
Does her life not matter at all any…
Nora’s not a person, Iris.
She never was.
Look, if we uncreate these forces, we can put everything back to normal.
Hopefully that’ll fix her too.
Barry, do you hear yourself right now?
Iris, I’m trying to save people.
How… how do you not see this is the right thing to do?
The right thing to do would be trying to get through to Nora.
Just like how we beat Eva, just like how we talked down Abra Kadabra.
That is what we do.
We tried talking to her.
All Nora did was double down.
There’s no reaching her.
Obviously we disagree on this.
Yes, we do.
I have to do it.
Then you’ll be doing it without me.
Wait… you want to go after a force of nature?
Yeah, if I can convince Nora not to kill Deon and Psych, then… Barry will see that she can be reasoned with.
But, how do we find her?
I mean, she’s the freakin’ Speed Force.
Well, if she finds us first, at least we’ll know she’s coming.
Holy crap… you guys gotta see this.
You see that bright spot at the center of you?
I think that’s kinetic energy.
Guys, this is gonna sound really wild, but…
Yeah, ’cause a ghost-hunting lens isn’t weird enough…
But, if Barry and I created these forces, what if there’s a little bit of each of them inside of us?
Like you’re all connected?
when you’re over by the door, your glow was brighter.
Like there’s something in that direction that was intensifying it.
That something is Nora?
Guys, we can use me as a divining rod to track her down.
Yup, that’s weirder.
Elemental Force Particles?
They’re the particles that created the new forces.
The lightning bolt that rebirthed the Speed Force was full of them.
Now if we can extract a sample of these force particles from the lightning, then we can send out an electromagnetic pulse that’ll seek out those same particles, wherever they may be along the temporal spectrum.
And you can erase the new forces from existence.
That’s not bad.
Small detail, though.
How in the world are you supposed to extract these particles from a giant bolt of lightning?
A few weeks ago when Barry was Spock-Flash, he modified the Tachyon Enhancer to siphon.
Mirror Monarch’s dark matter photons.
So all we have to do is tweak the Enhancer to siphon Force Particles instead of photons.
Tweaking the Tachyon Enhancer, and then send out an EMP to eighty-six the forces.
That’s genius. I mean it’s foolproof, even.
But it still doesn’t answer how we’re supposed to do this and protect the timeline.
I’ll figure out.
Somehow, I will.
I’ll figure it out.
Man, I wish Nash Wells was here.
I mean, he came up with most of these equations for the A.S.F. Machine.
I feel like he’d crack this easy peasy.
Modify the Particle Harness Collector.
I’ll be back as soon as I can.
Roger that, but where are you going?
To get the one person that can help us pull this off.
Oh, no… Tess.
President Bartlett just mixed up his meds.
That’s not gonna be good, but… great TV.
I’m guessing this isn’t a social call?
We need your help.
How bad is it?
Whether or not you can help us do the impossible.
Well, well, well.
Honey, I’m home.
Holy deus ex machina…
So, apparently, there’s danger in Central City.
Well, let’s get busy.
Well, you really think we can do this without affecting the timeline?
I know we can.
As long as we use me as your guide.
Harrison was there when the forces were created.
So if we used the other “him” from that night as a beacon to lock onto…
Hopefully I can go back to that exact moment, also bring Allen along for the ride, and he’ll collect the particles.
Oof, wait, so you can travel through time with a plus one?
It should work…
When Allen and I go back to that exact moment that those dangerous forces were created 17 days ago, I will… I will create a protective-time bubble from that moment until now, preserving those days in this timeline, and preventing anything from changing.
Which would also allow us to wipe out the new forces without altering any of the events that have happened since then…
[laughs] Yo! That is… that is trippy.
Cisco, this will work.
What about Iris?
When she sees everyone safe, she’ll come around.
She has to.
You’re not convinced.
I wasn’t either, when Allen told me about this, I thought of Tess.
I thought of my wife, and how my future with Tess was ripped from me.
Until this gift which has allowed me to relive every single day with Tess, but only because I took a chance.
We must be getting close.
She should be here.
Maybe it was a false positive.
Maybe since Nora is the Speed Force, her isotopic signature is all over the city by now.
So what do we do?
I don’t know.
But we are running out of time.
Well, Cisco always says you can’t solve a problem till you’re asking the right question.
Isn’t “Where’s Nora’s kinetic energy leading us” the right question?
The right question is “Where’s Nora?”
We’ve been trying to find the Speed Force when we should be looking for… the person.
So where would the real Nora Allen go?
Harness modifications complete.
Let’s get some time particles.
Actually, you know what? Um…
Let me run just one more diagnostic on the collection disc.
[muttering] I just need one more, just one more…
Yo, yo, Deon. [Laughs]
What’s… what’s uh…
What’s good, man?
You tell me.
Something drew me here.
Was it you?
I’m… I don’t think it was…
I’m sorry, who are you?
Who am I? Who are you?
Who is he?
Look, guys, all’s good in the hood.
All right, look.
Barry, this is Deon.
And… and Deon, this is Barry, who’s actually…
Owner of this, uh, fine establishment.
So you’re the landlord.
What’s that got to do with anything?
Deon it’s good to meet you.
Actually, you remember me?
I was with him, you called us one of the Urkels.
Oh, yeah… the cornballs.
Cornball. He’s so funny.
Who’s the egghead?
I’m a fellow…
Uh, visitor to Barry’s place.
You know, y’all are being real friendly right now.
But I think… [snickers]
I think y’all are acting like that because you’re afraid of me.
Now why is that?
No, we’re just we’re just making a… we’re just doing an experiment…
Now why do I get the feeling you’re reason I’m this way?
Because that’s true.
And I’m sorry.
I never meant for this to happen.
So please let me fix it.
Fix it? So I’m a mistake?
I didn’t say that…
You didn’t have to.
I can feel it.
You want to destroy me.
No, I want to save you.
There are three other forces… People like you.
One of them? She wants to kill you.
Now, she’s already killed one of the other forces…
The Strength Force, and she didn’t care when the person containing that force died too.
So I need to make it so the Still Force never found you.
It’s the only way to keep you safe.
I like being me.
Oh, I get it.
Oh, I get it.
No, I get it. I get it.
This is what you’re gonna use to do it, huh?
This is what you’re gonna use to make it like I neverexisted?
Not you, just the force inside…
Man, I am that force!
Do you have any idea what it’s like to be told that you shouldn’t be here?
I never asked to be born.
Deon, listen to me.
Look at what you’re doing.
Okay, you… you don’t understand what you are.
Yeah, I do.
I’m a god.
Maybe it’s time you understood that.
Time to bounce.
What the hell just happened?
I think your friend Deon just stopped time.
Yeah, he does that.
Why’d he leave?
Because I couldn’t stop him.
Deon just aged the harness a thousand years.
How bad is it?
But not hopeless.
See I figured if we can find some way to…
Somehow create some sort of…
I was working on the collection disc when Deon showed up.
I figured I better hide it just in case.
You’re a lifesaver.
[laughs] As for the vest, I’m used to working with junk.
I’ll just need a bunch of replacement parts from my garage and she’ll be up and running in no time.
With a little help, that is.
I’m with you.
I think Deon’s right.
We can’t just uncreate these forces like that.
Uh… so what, we… we we should just give up?
On this? Yeah, we give up.
Doesn’t that feel like the right thing to do?
Cisco, Nora will kill him if I don’t do something to prevent it.
Just like she killed Alexa.
‘Cause she’s not gonna stop until all the forces…
And the people connected to them… are dead.
Why can’t you see? I’m trying to save him.
He doesn’t want to be saved by you!
He just wants to be given the chance to be himself.
And Iris understood that.
Look, every second that we leave these forces inside Deon and Psych, people are in danger.
It’s only a matter of time before someone dies in one of Psych’s nightmares or gets killed by some kind of Deon time anomaly.
Not to mention Nora declared war.
She doesn’t care how many people she kills as long as the forces die.
Yes, you’re absolutely right.
And something needs to be done about that.
And I don’t have all the answers.
All I know is this can’t be it.
You guys understand, right?
I… I have to uncreate these forces.
Like I said, I am… I’m Team Flash all the way.
Cisco has a point, man.
If uncreating these forces is what you feel in your heart is right, I’ll take that voyage with you.
But all I ask is that you think… truly think about the choice you’re making.
Please fix the harness.
Iris, you were right.
These isotopic readings are off the chart.
Where are we?
The old Allen house.
This is where Barry’s mom was killed.
He also said this is where the Speed Force went when she died.
That old car is hella vintage.
Almost looks brand new.
Must be a collector or something.
We can ask him when we’re done.
Assuming we survive.
Caitlin called me about Alexa.
So it turns out, when Iris and I brought back the Speed Force, we also created three new forces.
It’s our fault that they’re out in the world hurting people.
So I feel like… I have to be the one to take them out.
You think they’re above saving, too?
I think it would be safer for everybody if they didn’t exist.
You remember when Wally first showed up?
Man, it wasn’t just that I’d found out I have a son.
I found out I have a son who kept getting his butt in trouble.
Boy, he was mad at the world.
There was one point he said to me that he wished he had never been born.
So I tried to get close.
And he pushed me away.
I tried to give him space, then he felt abandoned.
No parent is perfect.
But one thing I never stopped doing was trying.
And look at the man he grew up to be.
Strong. Kind. Good.
Yeah I get it, I… I do, but… I mean, these forces?
They’re not my children.
You said it yourself.
You brought them into this world.
Look, I know they’ve all done terrible things.
But what if they could change?
You never judge your kids for who they are now.
You help them become who they know they can be when they grow up.
So lead with love.
After that, it is up to them.
This is Barry’s old room.
[dramatic musical sting]
Esperanza, don’t kill me!
We need to keep them out.
Psych, stop. You’re hurting them… please.
Oh, they’re hurting themselves.
Sure, I pull back the curtain.
But what they see is up to them.
Now, before I show you your worst fear, why were you looking for me?
You’re looking for the Speed Force?
Why are you so desperate to find her?
Is it to hurt her?
I want to talk to her so I can help her.
Are you sure? Because I am feeling the pain that she has inflicted upon you.
How deeply she’s torn apart your relationships.
Your whole life.
Actually, the suffering she’s caused is quite beautiful.
That wasn’t Nora.
She’s lost control. Just like you have.
But if you let me, I can help you both.
I don’t need your help.
Besides, I can feel what you fear the most.
It’s the person you seek.
Well, your wish is my command.
Sweet dreams, my beautiful boy.
You’ll never measure up.
Okay. It’s working.
Now, when you’re close enough to cycle particles,
the disc will light up.
Guys, I appreciate you helping me.
Make sure the proton collection housing’s double-fused.
And it’s good to see you.
What changed your mind?
Look, this is dangerous.
And it doesn’t feel right.
But I’m always gonna have your back.
No matter what.
Chester. Let’s get it going.
Okay, so. Barry.
All you need to do is get close enough to the Speed Force lightning to collect a sample of each force.
The PHC and Timeless Wells’ time bubble should do the rest.
Wait for it.
[whispers] Wait for it.
We’re at 100% organic speed.
We need you…
I need you.
I remember this moment.
This is where it all started.
We should get to the roof.
You think you can be a good wife?
But you never will.
Everything you do pales in comparison to me.
Besides… how could you be a good mother if you never even had one?
I’m not listening to you.
You don’t have to.
You already know it’s the truth.
No. You’re not real.
There’s no escaping your own fear.
I know you’re still here, Psych.
Very good. Mm.
It is not every day that somebody can sense my presence in their nightmare.
I’m not just someone.
We have a connection.
I know you can feel that too.
Perhaps. It’s not going to help you, though.
Escape one nightmare and I’ll just serve up another.
Because there’s always more terror to unlock.
But before you had those powers, before you became a force. You were a person.
I’m talking to that person right now.
I have friends. I have a team.
They can help you fight this monster that’s inside of you.
We can help you regain control of your body.
What makes you think I’m not in control?
I know you didn’t… choose to have these powers.
And you shouldn’t have to go through this alone.
I know that we’re not flesh and blood.
But in a way… I’m… I’m like a parent.
So please let me help you.
Well, then there’s something I should tell you, Mother.
I hated my parents.
The isotopic energy readings are going down.
The forces are dying.
These fools gonna learn.
You mess with Deon. You get dealt with.
Another 20 seconds, and they’ll be gone forever.
Barry did it.
What is that?
I think that is an act of creation.
I have the particles.
Shouldn’t the forces be dying?
Perhaps they are. Somewhere.
In time, but right here? Right now?
They’re being born.
What are you doing to me?
I wasn’t able to get through to him.
And now it’s too late.
Boss, we can’t stay here.
Never judge your kids for who they are now.
You help them become who they know they can be.
They’re almost gone.
Everything just stopped.
The numbers are going back up.
It’s as if the forces are still here…
Iris was right.
You all were.
I couldn’t do it.
Yeah, me too.
Barry, I… um…
I went looking for Nora.
I thought that if I could just talk to her, that I could fix everything.
I ended up finding Psychinstead.
You were right.
I couldn’t get through to him.
And it probably would have been the same with Nora.
I should have listened to you.
No, I’m the one who should have listened.
Harrison told me about the birth of the forces.
Can’t believe how close I came to erasing them.
What changed your mind?
Even the forces themselves.
I could… I could feel how they would affect the future.
All the speedsters’ and heroes’ lives they’d shape.
Some of them were family, Iris.
Barry, we both know how dangerous these forces can be.
I mean, if you couldn’t uncreate them, and I couldn’t get through to Psych…
What are we supposed to do?
Together this time.
Joe helped me realize that we can’t judge.
Psych and Deon for who they are now.
We have to help them become who they can grow up to be.
‘Cause that’s what parents do.
There was a tremor.
And Alexa sat up and looked at me.
She was for a second, but she’s not anymore.
Which doesn’t make any sense, medically speaking.
What if us being back in sync is what woke her up for the moment?
And then she reconnected with the Strength Force.
Is it crazy to think that we did this?
‘Cause we’re all connected.
And if we woke her up once.
Then we could bring her back permanently?
Why is everyone looking at me?
I’d ask you to say, but… I already know the answer.
A man’s gotta be where his heart lies.
He’s just gotta learn to listen to it.
One more thing before I go.
Whether it’s me, or any of the many Wells predecessors,
I want you to know that you taught us every inch as much as we taught you.
Yeah, I’m never gonna get used to that.
For the first time in a long while.
Yeah, I feel okay.
Um…’cause I’ve been thinking about something.
And after tonight, I know I have to do it.
Okay, that’s just weird.
I was literally about to say the exact same thing to you.
[both] I have to leave Central City.
[snickers] Thank God.
Are you kidding me?
Oh, my God.
Babe, what are you gonna tell Team Citizen?
What are you gonna tell Team Flash?
