(elevator dings)
(sinister music playing)
Uh...
Can I help you?
This is gonna sound insane, but I, um...
I was just in an accident, and I found this file.
But what I saw inside doesn't make any sense.
(imperceptible)
Oh, my God.
We need to talk.
(Iris West) Six hours and 52 minutes ago,
Barry vanished right in front of me.
We don't know where he is, if he's in danger.
Or why he's not back yet. We don't know anything.
Whether he's even alive.
Since then, I've doubled back to the loft
to look for evidence at the scene of the crime.
Picked up some weird energy signature from the air.
Trace amounts of a radioactive isotope of cobalt.
Did anyone else just get a bad feeling?
I don't get it. What could leave behind radiation like that?
I'm not sure.
But isotopes like this don't just occur spontaneously.
Barry's disappearance wasn't an accident.
He was taken, which is even more terrifying.
Sounds like y'all could use some help.
-Mark. -Welcome back, man.
It's so good to see you.
I was just thinking about you. Where have you been?
Tundi, the Arctic, Corto Maltese.
Volunteering at a few different research facilities.
-What are you doing back here? -I called for him.
You knew how to get in touch with Mark?
A few months after I left, I reached back out to Cecile.
Guess I just needed a friend to talk to.
Khione, honey, I'm so sorry that I couldn't tell you,
but Mark wanted some space, and he asked me to stay quiet.
(Mark) I'm sorry too.
But I am done keeping my distance. Especially now.
Barry never gave up on me.
You know, even when I was at my lowest point.
So, I'm not ready to give up on him,
and I do not think that any of you are either.
I could try resetting our satellites to scan for the cobalt isotope.
And I can call Cisco at A.R.G.U.S., see if maybe they've heard anything.
I'm gonna go to the office and search the database
for anything about cobalt radiation.
I'll come with.
And Khione and I can recheck the loft and surrounding areas.
We'll make sure we didn't miss anything.
Wherever Barry is, we're gonna find him. I know it.
Hey, I found some more files that we can check out.
You okay? What's wrong?
I was searching for other unexplained disappearances in the database
and I came across this old draft.
I thought I deleted it, but I guess it was backed up.
Hey, Barry survived Crisis. And he's gonna survive this too.
You know, when we first met Nora,
she was from a timeline where Barry did vanish in Crisis.
So, she grew up without a father.
Living with the weight of that pain, I thought that this time around we would
give her a better life, one that she deserves. Together.
But someone's trying to pull us apart
so that Barry won't be here for a second time.
It's like my worst nightmare is coming true and I just...
I feel powerless to stop it.
(sighs)
Do you remember when I first saw that article?
I was just some smart-mouth kid with a record.
But, Iris, you took me under your wing.
You taught me to be a reporter and a leader.
So, let me help you.
And be there for you, like you've been there for me.
And I can start by grabbing you some tea.
-Chamomile, right, boss? -Yeah.
-Be right back. -Thanks.
Oh, hey! What are you--
(pressure whirring)
(hissing)
(all screaming)
We gotta shut that thing. Get everybody outta here!
Come on, people! Move!
What's happening?
Uh-uh. Get back in your office.
-We need to stop that leak! -No, you have got to protect your baby.
(coughing)
Look, if you wanna help, call for backup, okay?
(coughing)
Oh, my God. Aariz?
Oh, no. What's wrong with them?
Iris said it was a gas leak.
Must be halon from the fire suppression system.
Are they alive?
Their heartbeats are so faint.
If they were breathing in halon, their brains were starved of oxygen.
I don't know what we can do to help 'em.
I do.
What are you doing to 'em?
Growing plant cells inside their body to help them breathe.
Since when can you do that?
(both gasping)
Don't worry. Your lungs are just getting used to breathing again.
(gasping) My chest. It's on fire.
It's worse than breathing in tear gas.
What the hell did you do to us?
I'm sorry, I didn't mean to scare you.
Just give it a few minutes and your bodies will be back to normal.
I don't know what you are, but stay away from us!
(gasping)
What the hell was all that?
Hang on. Where's Allegra?
No.
Allegra. Wake up! Allegra!
Wake up, Allegra!
(Chester) I just don't understand. She's not waking up.
I mean, did the halon gas do this to her?
I don't think so. I'm so sorry, Chester.
She'd just left my office. She was trying to help me and...
(Gideon) I've finished analyzing Allegra Garcia's symptoms.
She appears to be suffering from acute radiation syndrome.
There's evidence of a blast of the cobalt-97 isotope.
So, she was attacked with cobalt radiation?
-That means whoever took Barry... -Also attacked Allegra.
Someone is coming after this team.
The radiation made Barry disappear.
It didn't put him into a coma like it did with Allegra.
We don't know that. He could be comatose wherever he went.
Hey, wherever Barry is and whatever happened to him,
we need to trust that he can take care of himself, 'cause right now,
we've all got targets on our backs.
Any one of us could be next.
Khione, what you did at CCC Media,
do you think maybe you could cure Allegra's radiation poisoning?
I can only expel the unnatural from people.
And the cobalt isotope is part of the natural order.
Let's lock this place down then, shall we?
Khione and I can survey the building together,
and Iris, for the time being, maybe you should wait in the time vault?
I can't help look for Barry from inside of there.
-What... -(Chester) Let me handle that.
I just started resetting the satellites to scan for the cobalt isotope.
The algorithm just needs another hour.
Okay. Let's stay safe, yeah?
We need to make sure that everyone is alive
when Barry gets back.
(Korber) It's unbelievable.
You look exactly like Detective Thawne.
-Do you have any ID on you, Mr. Gilmore? -Dr. Gilmore.
There a problem?
Sorry. No.
Wanna tell me again how you found this file?
We've been through this.
There was a lightning strike in my office at Mercury Labs.
When I woke up, it was there, staring at me.
And I suddenly had this feeling that I needed to know
more about Detective Thawne and why he looks just like me.
You think I'm crazy. You know what? Forget this.
Keep your classified file. I don't need it anyway.
Wait.
I worked with Detective Thawne.
And even though he was a vet and I was a rookie,
he went out of his way to make me feel welcome.
I don't think any of us ever really got over his death.
What happened to him?
His cause of death was redacted in the report.
Never got an official story.
(scoffs)
Sadly, not the only mysterious death to happen in Central City.
(mysterious male voice) Find her.
Did you hear something?
Hear what?
(mysterious male voice) Find her!
I'm sorry. I need to leave.
Wait. Please. Let me help you!
Lounge looks clear.
-You okay? -Yeah.
Are you upset I've been in touch with Cecile?
No, not at all. I'm glad you had someone to talk to.
It's just these last few months,
there were so many things I wanted to talk to you about.
I guess you just didn't wanna talk to me.
Hey. Listen... (sighs)
Look, I spent the last seven months trying to get my head on straight.
You know, so that I could accept my grief.
Which I think I have.
But, uh... (sighs) I also learned that...
sometimes people grow apart.
Not when you have a bond like we did.
I know we had our problems, but I forgave you before you left.
For everything. So, what changed?
You did, Khione.
You are not the same person you were when I left.
What you did to those people tonight...
They were dying. I needed to help them breathe.
Oh, so you turn 'em into mutant plant people?
I used nature to bring air to their lungs.
Khione, there was nothing natural about what I saw today.
You warped their bodies. You made them into monsters.
What... What right do you have to do that?
I didn't have a choice. I saved them.
Saved them? You tortured them.
They could barely speak. Their skin was green. You hurt them.
I would never hurt a living being.
Really? Did you notice they didn't say thank you?
They ran away.
Before I left Central City,
I told you there was something amazing inside of you.
I really thought you were gonna be a hero.
I was wrong.
Khione, you...
You're an abomination.
Iris, I know that you're hurting right now.
I can feel the despair pouring off of you.
These last few months getting everything ready for Nora,
painting the nursery,
letting myself dream of the world that's ahead of us...
It was too good to be true.
Every time something really great happens,
something worse comes along and just cancels it out. So...
Iris, Barry will come home. He always does.
(trilling, keyboard clacking)
-Mark? -Khione's gone.
We were doing a perimeter sweep in the lounge and she just bailed.
What? Why?
When we were at CCC Media,
Khione really scared the people she was trying to save.
She said she felt like a monster.
But Khione wouldn't just leave us, not while we're in danger.
I was so excited to see her again.
So excited to reconnect.
And then she just left.
It was like losing Frost all over again.
I'm so sorry, man.
I know how hard it was when she died.
After Frost came back from fighting Deathstorm,
Caitlin had her in the med lab.
I never should've left that room, man.
Maybe I couldn't have saved her either, but at least I could've been there,
at her side to hold her hand.
To tell her that I loved her before she...
Uh...
Maybe when I'm done resetting the satellite,
I'll, uh... I'll go check on Allegra.
Yeah. (sniffles)
You know, I'm not doin' anything right now.
You just need to recalibrate the scanners
to look for cobalt radiation, right?
Yeah.
I could finish it for you if you want.
-Really? -Of course.
-Thanks, man. -Be with her.
-(Malcolm humming) -(dance music playing on speakers)
(people chattering)
(mysterious male voice) Find her!
(groans)
Find her!
Who's saying that?
Find her!
Who are you?
No! Eddie!
("I Guess That's Why They Call It the Blues" playing)
It's you, Iris West.
Screw the future.
(chuckles)
Screw the future.
Iris West. Iris West. Iris West.
(Mark over PA) Hey, guys! Picked up some Big Belly Burger for you.
Come and get it.
Hey, yeah. Thanks, Mark. I'll come grab it. Be right back.
What the hell?
Cecile?
Mark. What the hell's going on?
Oh, Mark isn't here right now.
(distorted) But he served his purpose, didn't he?
To get all of your teammates out of the way.
So that I could get to you. The avatar's lightning rod.
You're the Negative Speed Force, aren't you?
Now, I'm gonna do what I've wanted to for a long time.
I'm going to gut you like a fish. And your little baby too.
Time to eliminate the competition, permanently.
Leave her alone!
Nora, are you okay?
Does she seem okay to you?
(groans)
You can't stay on this plane of existence forever.
Not in the state you're in.
And the moment you leave to go and heal, I am coming back for her.
And the entire Allen family!
(panting)
-(groans) -(Cecile) This is crazy.
We trusted Mark. He was supposed to protect us.
Turns out he was hunting us the whole time.
He distracted me from the satellites, and he must have upset Khione too.
-To make her leave. -Does this mean he's the new avatar?
No. Mark's body is just a vessel.
Whatever they're trying to use him for, it's unlike anything I've ever seen.
-(groans) Oh. -(Chester) Whoa.
Yeah. The Negative Forces,
they're attacking me right now, on the cosmic plane.
Trying to distract me from whatever their plan is.
(Iris West) Oh, my God.
Is that why Barry can't get home?
Because he's being held captive somewhere?
I think so.
Because his connection to me,
it's been disrupted ever since he's vanished.
I can't find him.
Anywhere in time or space.
Chester, you need to get the cobalt scanners online, fast.
I'm really trying,
but Mark sabotaged all the work that I had already done.
(Iris West) Well, try harder, please!
He wants to kill my baby, my family, and we don't have a way to stop him.
There's still someone who can help us. Khione.
Come on!
There's gotta be something about you here, Eddie.
I need security to the CEO's office, right now!
No. I just need to talk to Iris West.
So, you broke into her office?
You need to leave.
She used to know someone. Eddie Thawne.
I need to find out what happened to him.
It's a matter of life and death.
- (Joe) Eddie! - (Iris West) Eddie!
(grunts)
What did you do? What did you do?
(Malcolm) That's how you and I met.
What did you do, Eddie?
(door closes)
In here!
I need to see how he died.
(Iris West) Gideon, can you start a recording?
For Barry's eyes only.
Yes, Iris West-Allen.
Can you show me a picture from our wedding day?
Barry, I have no idea how this is gonna end.
We're under attack from the Negative Speed Force.
Deep down inside,
I have a feeling that right now, you're under attack too.
Tonight, a new world begins.
No matter what, I know that the love that we share
and the connection that we have can never be broken.
Because we will never stop fighting for it.
I felt so powerless today.
But I guess this is me saying that I'm standing on my own two feet.
And I'm gonna be strong.
And I know we'll find our way back to each other.
We always do.
What is happening? Did you just summon me?
-Who are you? -I'm the Speed Force.
(groans)
Are you okay?
No. I used up some of my last bits of strength to bring you here.
(groans)
I can't help your friends.
Not anymore. It's up to you.
I can't help anyone.
Even when I try, I hurt people.
That's what a friend of mine told me and he's right.
I'm inhuman.
I know. That's the point.
Human emotions, human feelings, they give us strength.
But they can also weigh us down.
Look what happened to you today.
You were so blinded by emotion
that you couldn't see the truth right in front of you.
That Mark wasn't really Mark at all.
Well then, why don't you defeat him?
Because my power is fading.
I am running out of time, Khione, and so are you.
But you are still denying who you really are.
No. I... I... I'm not denying anything.
I tried to figure out who I am,
what my powers are, where they came from.
Seven months ago, you made it snow.
Today, you transformed people's physiology
with a thought.
What else have you done?
(chuckles softly)
I can become any element.
I've rescued people, animals,
entire ecosystems from invading unnatural assailants.
I can feel everything.
All over the planet.
A volcano exploding in Bali, a blade of grass in Peru.
Every living thing.
Sounds to me like you already know what you are.
(groaning)
Please, Khione, help your friends.
Embrace your power.
What if I can't?
Then your team, this city,
and everyone on the planet will suffer.
-What's happening? -I got the cobalt scanners working.
They picked up on Mark's signature.
Wait. Isn't that...
Caitlin's old apartment? Yeah.
Oh, whoa, whoa, whoa.
The barometric pressure there just shifted 1,000 millibars.
That's like a hurricane's about to hit the place.
No.
That's no hurricane.
I've been waiting for you, Khione.
You're the only one left that I have to take off the board
before I can get everything I want.
The only one who can protect her.
So, let's do this.
Bring it on.
Something's different about you.
The Speed Force helped me embrace all the power that's inside me.
And it is a lot of power.
But I don't wanna hurt you. So, I'm gonna give you one more chance.
Leave my friend's body
and crawl back to whatever hole in the universe you came from.
(laughing)
There's not a chance.
See, if you wanna take me out, you've gotta murder your best friend.
What are you talking about?
Oh. Did your life coach not get into the nitty gritty with you
when she gave you your little pep talk?
(chuckles)
So, here's the deal.
Mark is still in here.
And I am not leaving this body.
So, if you wanna stop me, really stop me,
the only way is to kill Mark.
(exhales)
Gideon, can you scan me for anything unusual?
Of course. Scanning. You're having mild contractions.
I'm in labor?
(gasps)
So long as I have this crystal...
I am in charge.
I know.
That's why I'm removing it.
(distorted scream)
(grunting)
(screaming)
Sorry, Mark.
This is gonna hurt.
(coughs)
What the hell?
What did you do to me?
I saved you.
Where'd that thing go?
I don't know.
But it can't be good.
Frack, yeah! I'm not picking up cobalt radiation anymore.
-Yes! Yes! That means Khione won, right? -Yeah, yeah.
(groans)
What's wrong? What happened?
Oh, God, I'm just... I'm getting a massive wave of panic.
-Wait. -But... also, joy.
Guys, the baby's coming.
Iris, honey, that's great news.
Hey, are you all right? I'm getting a lot of wild emotions off of you.
Yeah, no. I am really happy, I am. I just...
I thought Barry would be back in time.
Guys, what's that?
-Barry? -Iris.
Is it really you?
Yeah. I'm back. I'm back.
Oh, man, I knew you'd find your way home.
Yeah, I did too. But, uh, Barry,
we gotta get Iris to the hospital, like, now.
-Right now? -Yeah.
We're having a baby.
-(Iris West groaning) -(Barry) There you go. You got this.
-Okay. -Yeah?
-I think they're gone. -Okay.
(groans) Ooh.
Iris?
(chuckles)
I didn't think you'd enjoy contractions.
Oh, no, they're horrible. I just...
I don't care. As long as you're here.
I'm just sorry that I wasn't there for you today,
everything that you went through.
I always knew that someday my life would lead me back to that night.
The night my mom died.
I just thought that when it came, I'd be afraid, but I wasn't.
I got the chance to see my parents again.
And I felt peace.
I'm home now. I'm not going anywhere.
I love you, Iris.
I love you.
(exhales sharply)
She's doing great.
-Oh, thank you. -Ah. That's terrific.
Allegra's almost done with her iodide treatment.
She'll be here any minute.
Oh, tell her to take her time.
The doctor says we still have a few more hours
before the baby arrives.
Now we just need to hope that crystal doesn't show up again in the meantime.
Nora said Mark was possessed by the Negative Speed Force.
Look, whatever that crystal is,
it's unlike any weapon we've ever seen before.
It's traveling through time,
trying to use our friends to kill us all through the timeline, all at once.
I'm gonna go and start looking for this rock
before it finds another victim.
Mark, are you sure you're up for that?
You were just reborn.
Yeah, I feel fine. You know, physically.
I'm just glad you're back. I missed my friend.
When I was away these last seven months,
I thought about you all the time.
I was wondering how you were doing. Now look at you!
You've already become even more powerful than I ever could have dreamed.
You saved me from the Negative Speed Force.
How did you do that?
I returned you to Earth.
The mother of us all.
And once you were safe in her embrace, I raised you up.
Khione, that kind of power...
What even are you?
I'm a goddess.
So, what, you're like the Speed Force now?
Not exactly. I'm not just connected to one Force or one element,
but all of them.
And if I'm gonna explore what that really entails...
I don't think it's my destiny to protect just this team, or this city.
Everything's gotta change.
What are you saying exactly?
I don't think I can stay here.
With you, with this team.
I think I need to leave.
Uh...
-What? -Not yet.
First, I'll help you stop the Negative Speed Force.
Look, Khione, whatever you need, we-- (yells)
Oh, no! Barry!
I can't feel him anymore.
He's gone, again.
(panting)
(Korber) Malcolm!
Stop what you're doing, okay? This is a crime.
I need to see his corpse.
It's the only way I'll know the truth.
About what? This is insane!
I look like him.
I have visions of his memories.
And there's this voice in my head,
-pushing and pushing. -You can't be him.
It's all just coincidence.
(laughing)
No such thing as a coincidence.
(panting)
(gasps)
(groaning)
I couldn't wait.
I love you.
Detective.
(Joe) Eddie, we need your help.
Iris West...
Eddie?
Eddie!
(Joe) What did you do? What did you do?
What did you do?
Eddie, no! Stay with me, okay? Stay.
-(sobbing) -(groaning)
(Iris West) No!
No! Eddie!
I remember everything.
I shot myself.
In the chest.
That wasn't you. Now put your hands behind your back.
I am Eddie Thawne.
And I'll prove it to you.
(groaning)
Now do you believe me? u.
