My name is Oliver Queen.
After 6 months in hell, I have been released from prison
and returned home with only one goal...
to save my city, but things have changed.
Instead of operating outside the law,
I am now working alongside the police.
I am no longer inmate 4587.
I am once more the Green Arrow.
Previously on the Flash...
Dr. John Deegan,
use this book to reshape the world
as you see fit.
I can see everything.
Barry, are you OK?
I'm Barry.
I'm Oliver Queen.
Maybe it's just Earth 1 that's been affected.
If we can get to Earth 38 and find Kara,
if she remembers us, then maybe she can help fix whatever's happening.
Whoa, Lois. Wait, wait.
This is Barry and Oliver. They're friends.
So you know that I'm Oliver and he's Barry?
- Why wouldn't I? - We could use your help.
I vibed somebody in the speed lab,
some guy with ridges on his head.
I know where to find him.
So what's our next move?
We're going to Gotham City.
Ohh!
OK. I know this sounds nuts and completely unscientific,
but I think that freaking lightning is following us.
- Focus, Curtis. - This is me focusing.
These atmospheric anomalies are playing all kinds
of hell on my equipment,
plus you don't want that lightning to hit
when you're engaging Deathstroke's son.
I just had to say it.
Kane Wolfman, you're under arrest
for 19 violations of international law!
Really? Does that include the murder of...
1, 2, 3, 4...
4 A.R.G.U.S. field agents?
Last chance! On the ground now!
This isn't personal. Just business.
Son of a bitch.
Is that any way to greet your friends?
All I know is that whenever the three of you show up,
it usually means we have one huge problem.
So you're you.
And you're you.
An immortal Egyptian, aliens, parallel Earth Nazis.
I have no idea why I'm not even surprised at this point.
I'm still trying to figure out if this is
more like Freaky Friday or Quantum Leap.
No. If this were like Quantum Leap,
I'd only look like myself in the mirror.
Yep. You are definitely not Oliver Queen.
We think that the red skies
and these lightning strikes have to be related
to whatever happened to Barry and Oliver somehow.
We need you to solve the somehow while we're in Gotham.
No problem. I mean, A.R.G.U.S. has
all the best analytic toys,
but what we really need is a pattern recognition algorithm,
and, unfortunately, Felicity isn't...
- I called Felicity. - Wait, wait.
- You called Felicity? - Yeah.
OK. Right. Well, I guess that makes sense
because technically, you are her husband.
I'm confused.
I've been summoned?
- Yes. Thank you for coming. - Of course.
I mean, things might be fraught between us, Oliver.
That doesn't mean I'm not gonna show up.
They are? They are?
They are. Yeah, which is... Sad.
So, um, this lightning thing.
Um, could you help me out with that?
Can I kind of show you kind of what I'm thinking?
- Yeah. - OK.
OK. So why didn't you tell Felicity?
Well, because we tried to tell everybody at s.T.A.R. Labs,
and it didn't really go over so well.
Felicity and I have enough problems as it is
without introducing body swapping.
We thought we'd just let her think everything's
normal and that Barry and I are solving
another problem.
If you find out how this lightning thing
relates to whatever it is that we're dealing with here,
can you please tell us?
Copy that.
Hey. This thing isn't gonna be permanent, is it?
- I hope not. - I hope not.
Jinx.
Oh. Barry, there's something I'd like to discuss before we go.
- What's that? - That you probably shouldn't go.
What?
Oliver Queen is a public figure
and an infamous vigilante.
If you are in Gotham City, you're attracting
the type of attention that we don't want.
No. If... If Gotham can handle the Batman,
it can handle the Green Arrow.
The Batman's an urban legend.
Wait. You don't believe Batman's real?
He's not real. He's an urban legend
concocted by the Gotham police department
to scare criminals.
And I'm the original vigilante, Barry.
OK, if you guys are done fooling around...
actually, you know what? Could you pull that thing up?
Because, unlike you, my identity's not public,
and I'd like to keep it that way.
This isn't your real face!
It might end up being my real face
if we don't sort this mess out, so could you?
- Happy? - Ecstatic.
Apparently, you guys aren't done fooling around.
Well, I guess I'm running alone.
Ho ho ho! That is so awesome.
So this is Gotham.
Doesn't look so tough to me.
Where's Oliver?
Huh. I don't know.
Guess he's still getting the hang of it.
Ha ha ha!
I'm still getting the hang of it.
All right. All right.
So how do we find two people
in a city of 1.6 million?
There is a radio personality named Vesper Fairchild.
She knows everyone in Gotham,
and I know her.
She was doing an exposé on white-collar crime
back in the day, and I wanted to persuade her
that Queen consolidated was above board.
So you slept with her, right?
No. I... I don't know.
Gosh. You really got around back in the day, didn't you?
Oh. One time, Oliver cheated on his girlfriend
with her sister.
- Barry! - Oh, no! Ohh!
What? You did!
So, what, depending on this past relationship with this woman,
we might have to come up with a plan "b."
Is that what you're saying?
- Yeah. - Guys!
Take a look at this.
You still think he's a myth?
Yeah! Let's go.
Batman's real.
Come on.
If I remember right,
the radio station was this way.
I'm surprised they put it in the bad part of town.
It's cute how you think there's a good part of town.
Looks like the one percenters
bring the good part with them.
This is why nobody talks about Gotham, OK?
City might as well be dead.
Sounds like you guys aren't from around here.
Probably don't know,
but Gotham tourism Bureau collects a tax
on out-of-towners,
so phones, wallets, watches now.
You know what, fellas? I... we don't want any trouble,
so maybe we can just talk this out, OK?
Talk it out.
OK. I'll talk first.
Hey!
Agh!
Oh, great.
On the ground now!
All of you, on the ground! Show me your hands!
Oh, crap.
I need SWAT at Nolan and Burton.
Green Arrow sighted at Nolan and Burton.
Sir, we don't want any trouble.
Yeah. Tell that to Oliver Queen here.
Oliver, stand down.
Pattern recognition algo is locked and loaded.
Bringing it online now.
You realize that this may not work, right?
Like, there may not be a pattern to recognize.
Is there a suggestion bound within that dose of pessimism?
Does the energy discharge of the lightning
look familiar to you?
The quantum amplitude is consistent with a dimensional breach.
Exactly. We're gonna need Cisco's help on this one.
I've been summoned!
OK. That was a disturbingly coincidental entrance.
It wasn't coincidental.
We'd been getting the same red skies
and freaky lightning in Central City,
and I'll tell you this much... it wasn't speed force.
Wait, wait. Hold up. "We'd been,"wasn't,"
as in past tense?
Interestingly, the atmospheric Phenomenon ceased
the moment Barry and Oliver left Central City.
It's like it packed up its bags and followed them here.
That's why we came.
The Phenomenon has to be related to Barry and Oliver's...
- OK, Caitlin. OK? - Body swap?
Ahem. Don't... don't say... ahem.
I'm sorry. Body... body what?
You, uh... you didn't tell her?
Again, tell me... heh... what?
Um, excuse me, officer.
Were you able to get in touch with Laurel Lance
at the Star City D.A.'s office or...
yeah. She said, uh, "I think a night in jail
would do them some good."
Heh.
What were you thinking?
That you were about to get yourself shot.
- You're welcome. - I was deescalating
the situation, you know, like, uh...
- like I would? - Uh-huh!
Guess what, man.
I handled it exactly how you would!
OK. You guys, maybe taking on each other's personalities
worked for amazo, but you were not gonna
talk your way out of getting mugged,
and you escalated the situation way too fast.
So what would you have done?
What I would have done is supersped us right out of there.
All they would have seen is a gust of wind.
I mean, hindsight is 20/20,
but we'll follow your lead next time.
Because there will really be a next time
when someone threatens 3 superheroes with a gun.
Good news.
Somebody posted your bail.
- Who? - I don't know.
Guess someone wanted to make you guys their headache
instead of mine.
We'll show ourselves out.
Please come with me.
I'm guessing this belongs to whoever bailed us out.
I really think we've had
enough distractions for one night.
Yeah. I agree with my friend.
We appreciate the early release, whatever,
but we're really fine on our own.
I'm afraid my employer insists.
OK.
And you said it wouldn't happen again.
Bruce Wayne got us out of jail?
Doesn't sound like him.
No, it wasn't. Wayne left Gotham 3 years ago.
Why? To go where?
No one knows.
So who's Manning the shop now?
Apparently after he left, Bruce's board of directors
went to town with a bunch of aggressive get-rich-quick deals.
Yeah, but an abandoned building
didn't bail us out, right?
Whoa. That is definitely not Bruce Wayne.
Oliver Queen.
Ahem.
Yeah, yeah. I'm Oliver Queen. Yeah.
- And you are? - The rain on your parade.
If you're visiting Gotham to compare grappling hooks
with Batman, you are out of luck.
No one's seen him in years.
Told you.
Myth.
I would never compare myself to a total badass
like Batman.
What I think Oliver is trying to say
is thank you for getting us out of jail.
What Oliver's actually trying to say is
who are you, and why are you helping us?
Gotham has enough problems without a guy
in green leather showing off his Arrows to everyone,
so the faster you find what you're looking for,
the faster you can get the hell out of my city.
Uh, but, what... what should we call you...
rain, Ms. Parade?
Kane, Kate Kane.
She's cool.
You didn't tell her?
Oliver... the actual Oliver thought they had
enough problems with Felicity already.
Oh, and you didn't think to loop us in on the fact that you
were keeping the Freaky Friday situation on the hush?
I was thinking it was more like Quantum Leap.
Well, if this were like Quantum Leap,
they'd only look like themselves when they see themselves in the mirror...
It depends on what type of Quantum Leap...
Shouldn't we concentrate on what this lightning came from?
- Right? - Right, but...
Oh. Ahem.
OK, guys. You don't need to tip-toe around me.
It's just a lot to process.
It's not every day that you find out that your ex
is your husband and vice-versa.
Yeah. Iris was, pretty freaked out, too, when she sussed it out.
Wait. Iris.
You know, actually, John... right before you came in,
John was just saying that we need to really handle that lightning...
Iris was able to tell that something was off with Barry?
- No, not exactly. - Oh, totally. I mean,
it was like lover's intuition. - Stop.
That's how you can tell these two were...
you know, Felicity, um, there's something very strange going on here,
so I wouldn't take this as a commentary
on you and Oliver's marriage.
No. My marriage with Oliver is strained
by the fact that we've become different people...
quite literally in Oliver's case.
If the lightning strikes are attempted dimensional breaches,
there might be a way to stabilize the quantum flux
to allow whatever's trying to get through to get through, right?
- Yeah. Of course. - Yeah.
You guys try facial recognition?
One of Bruce's R&D guys still works in the building.
I can give this to him.
Uh, we did try it,
so thank you, but no luck.
Besides, I'd think if Wayne's R&D's
in the same shape as this building,
it's not gonna really do us any good.
Suit yourself.
Seems strange, doesn't it,
that Bruce Wayne and Batman disappeared
from Gotham around the same time.
Well, when Batman left, the city went
to 5 different kinds of hell,
which for Gotham is really saying something.
Took a toll on Bruce.
Is that why he left?
Still trying to figure that out.
Right, but you work for him,
and you don't know why he left?
Who said I work for him?
How'd it go with Vesper?
She hung up on me.
Apparently, I did sleep with her.
- Hmm. - OK. The building is
under renovation, so this is
the best place for you guys to work out of.
Oh, and the, uh, wi-fi password's "Alfred."
So if Vesper's not gonna help us,
we're just back at square one.
No, we're not. I lifted this off
of a computer at the precinct.
It should have the entire GCPD database.
You stole data from the police?
No. No. The flash did it.
- It's not funny. - I'm not laughing.
Did you lose the coin flip on who has to come talk to me?
We didn't flip coins. We drew straws.
I'm kidding. Actually, I wanted to come talk to you
because I think I've got a little bit more experience
with alternate realities than you do.
So what words of wisdom do you have for me?
That Iris probably has a little bit more experience, as well,
and maybe that's why she would have seen
something that you didn't.
As for Oliver keeping you in the dark,
when he and Barry tried to tell us what was going on with them,
we knocked them unconscious and locked them in the pipeline.
- Seriously? - Wasn't our finest moment.
Look. I'm sure that that's the reason
that Oliver didn't want to take any chances with you.
I appreciate you saying that...
But it's just another excuse in a long list of excuses
for Oliver's behavior.
Oliver does love you, Felicity.
Yeah? Well, what's love without respect or trust?
I don't know,
but as long as there is love,
you can't give up on it.
That's the one thing I do know
after everything I've been through,
everything I've suffered.
Thank you.
Well, one good thing about what's going on
is that I have something to distract me.
Look at this.
- That looks like... - A quantum flux anchor.
I'm pretty sure if we build it,
whoever's trying to breach through will come.
Let's get to work.
You really know your way with a computer.
Well, when I was first starting out, I had to hold my own
before Felicity showed up.
Got him. John Deegan.
Oh. Illegal experimentation, torture.
Hmm. Seems like he was conducting experiments
on his own patients' brains.
Sounds like a real charmer.
Well, he was acquitted. All the charges
were dropped on technicalities.
So where can we find him now?
- No known address. - What about employment?
Well, he was fired, suspended
by the medical board for two years,
but that was... 5 years ago.
- So no idea where to find him. - No.
Except somewhere in Gotham.
Needle in haystack.
- All right. - Where you going?
I'm gonna put on my work clothes
and do an X-ray flyby of the city.
I don't think miss Kate would be too thrilled
with us running around her city.
Well, unless she has some kryptonite stashed somewhere,
I'm really not worried.
Heh. You lost?
No. No. Um, just needed to clear my head for a sec.
Actually, you know what?
I'm sorry
about the third degree earlier.
I guess the name Bruce Wayne carries
a certain notoriety.
Oh, I know. Bruce Wayne's my cousin.
Your cousin?
That makes a lot of sense.
Actually, I'm in the process
of turning this building into a real estate development firm,
so this is me hijacking his office.
My cousin's actually friends with Bruce.
Um, well, frenemies.
- Hmm. - Heh.
Do you ever wonder if trying to keep
his private life from the public eye
just got to be too much for him and he broke?
Heh. Sitting at that desk,
staring out that window,
watching this city that we grew up in
rot at its core,
you find a way to not break.
Bruce didn't leave Gotham without a fight.
Hmm.
You know, I got to say, all the corporate billionaires I know
wear versace and have 500 fewer tattoos.
Hmm. Those are the ones that you can see.
Well, that's a mystery.
Oh. Is this the... the old bard himself? Ha!
Hey. You... you wouldn't happen to know a John Deegan, would you?
I would, actually.
He's a doctor at arkham asylum.
Ah. I have to go tell the boys.
Uh, hey. Thanks for the help and the chat.
What the hell is this?
No offense, but you'd need, like,
5 Ph.D.s for the dumbed-down version.
How about the very dumbed-down version?
It's a quantum flux anchor that utilizes wave theory
to fire nano-particulates
across an Einstein-Rosen Bridge
to create a secure claxon field.
How about the very, very, dumbed-down version?
Felicity made a magnet that will draw whoever's
trying to breach through to us.
You could have just said that.
All right. Field's stable.
All readings are in the green. You guys are good to go.
I'm reading multiple quantum surges.
I don't think this is working!
This is what working looks like!
Man, Voice cutting in and out: Ca... you... Hear me?
You've got... To... Get... Book.
Jay?
Only... Book... Make this right.
If you get the book, you can fix this.
Am I the only one who thought that was very cool?
So we're sure he works here?
Well, it's probably too late for him to still be at work,
but if we find his office, maybe
we can find his home address or something.
Do you think you have enough of a grip on your powers
to do a superspeed reconnaissance?
I don't think that we should risk it if I don't.
OK. Well, then, we break in,
do some old-fashioned snooping.
- Ohh! - Aah!
Aah!
- Got new intel. - Those lightning strikes,
they were a flash from another dimension
trying to breach to us.
We think it was Jay Garrick
or a Jay Garrick.
He said to fix the situation,
we have to "get the book."
John Deegan was reading a book
in the drawing Oliver drew.
OK. So we find the book in there
or we find Deegan, and we make him tell us where it is.
Wait, wait. Hold on. Another flash from a parallel universe
just lightnings in, tells us to jump, and we ask, "how high?"
If we want to sort this thing out, then yes.
I have no idea how we're gonna break into a mental asylum.
I have some ideas.
Uh, how can I help you?
New patient transfer from Gotham Central Hospital.
Dr. Danvers said arkham was the more appropriate place
to treat her... Condition.
What's the diagnosis?
Persistent subthermal homeostasis
with, uh, involuntary gelid substantiation.
She gets cold and freezes stuff.
Yeah. We got a few of those in here like that.
- Fill this out. - OK.
We'll take it from here.
Officer Allen, it really is very...
this is a GCPD-A.R.G.U.S. operation.
We don't need your help.
Whew.
Barry... I mean, Oliver, look.
John Deegan.
Oliver Queen! Ha ha! Whew.
It's a genuine pleasure to meet you, sir.
He knows who you really are.
Gentlemen, I was thinking,
"why did I not become the flash?"
And it seems changing reality itself,
it's got a bit of a learning curve,
so, yeah.
This actually explains a lot.
You did this to us?
You can undo it.
That is true, but I think the question is,
um... why would I want to?
What the hell did he just do?
He bought himself some time.
What's happening?
Trouble.
The crazy bastard let all the other crazy bastards
out of their cages.
All right. Get the patients back in their rooms
and find that book.
Finally, the inmates are running the asylum.
Not for long!
Fries, fries, fries, fries.
Come on. Where is it?
Are you OK?
My cryostasis shut off when the locks did.
I... I need to be cold.
196 below zero. 196, he said.
How does this thing work?
OK. Maybe you should just take a step back.
Just get away from me!
Ohh. You cold bitch.
Unh!
Aah!
Agh!
No sign of Deegan or the book.
What the hell are you supposed to be?
Nicely done. Floor it.
Aah!
Who's this badass?
Agh.
That's... not Batman.
Kate Kane told you to get out of Gotham.
You should have listened to her.
I've been all over this place,
and I can't find anything.
Guys, I could use a little backup.
On it.
There you are.
Took the words right out of my mouth.
Slippery.
Listen to me.
Caitlin.
Wait. No, Oliver.
Hey. Remember what happened in central...
Oliver!
Oliver's not here.
In fact...
No one's coming to save you.
You should have killed me when you had the chance.
You left me to die on Lian Yu.
Unfortunately for you... heh heh... I didn't.
Does anybody copy?
Because... I think we have a new problem.
Come on. You can do better than that.
You're a killer, a depraved monster
who found a way to channel his darkness
and pat himself on the back for it!
You'll never beat me. Too slow, big heart.
Mama raised you right, so right,
you couldn't stop me from killing her.
Your father took the coward's way out,
and all these years, you told yourself it was brave,
but he was a coward just like you.
A failure.
Selfish.
Slow.
Pathetic.
Who the hell are you?
No. Seriously, who are you?
Your friends were exposed to a powerful hallucinogen.
Are you guys all right?
Define all right.
So how does a book make people change bodies?
Deegan said he was using the book to change reality.
Same question. How does a book change reality?
We'll figure that out when we get back to Star City.
Guys, we're gonna need some help with this lock.
Good. Then you'll be leaving Gotham.
You guys have caused enough problems for one night.
Hey. Would hitching a ride in the Batmobile be out of the question?
Get... out.
Sure.
- She really is like Batman. - Yep.
I don't do tearful good-byes.
No. I... I just wanted to wish you luck.
Wherever your cousin is,
I'm sure he's really proud of you.
X-ray vision.
You really do have a lot of tattoos.
Somehow, I feel like Kara Danvers doesn't have a single one.
You know, it's such a shame I have to go
because I feel like we would make a good team.
World's finest.
Oh. Look who finally came back.
With what looks like a fairly infamous book.
A book with a cryptographic lock on it.
Can you get to work on opening it, please?
We don't have a lot of time.
OK. Geek squad, form up on me!
Not much of a heartfelt reunion.
She's getting used to everything.
Do you want me to talk to her as, you know, you?
I think I'm in enough trouble with Felicity as it is,
but no offense.
Hey. Can I talk to you for a minute, then?
- Yeah. What's up? - I just wanted to see
how you're doing.
I'm compartmentalizing.
I'll fix things with Felicity later.
I don't mean with Felicity.
We both saw some stuff back at arkham.
I saw evil flash.
Eobard Thawne.
I saw Malcolm Merlyn.
- Oh. - I knew you'd been
through a lot, but...
I don't know, man. I never realized.
I don't know how you do it.
I wouldn't be able to live
with the Burdens that you carry.
Yes, you would.
Barry, I always thought that you had it easy,
everything was just sunshine and rainbows
and... everybody likes you.
You have real steel in you, my friend.
You can carry any Burden thrown your way.
Some unsolicited advice?
Hmm.
Don't wait to work things out with Felicity.
Our line of work, you never know how much time you got.
Not only is the lock cryptographic...
It's metaphysical. The readings I'm getting off this thing
are nuts... and, yes, that's a technical term.
Um, may I speak with Felicity for a minute?
Sure thing, Barry... Oliver... Boliver.
Stop helping.
This must be strange for you.
Oh. What gave you that idea?
I don't know. Maybe it's easier for you to hear this
coming from... Barry Allen.
What a stupid...
hear what?
That we're gonna be OK.
People change, Felicity.
It means we're growing.
It means we're evolving,
except for one thing,
one thing that will not change...
Is how I feel about you.
Love is too small a word...
And no matter who you are
or... or what you become,
no matter who I am
or... or what I become...
You will always be...
you will always be the love of my life.
People change.
That never will.
Oliver, I...
Jay?
- No. - Oh, my god. Dad?
My name is Barry Allen.
Hello, John.
Do... do I know you?
You're not wearing your ring.
Things must be different here.
Barry, where's there?
My Earth, Earth 90.
I've traveled from there to warn you.
- Warn us about what? - His name is mar novu,
but he calls himself the monitor now.
He's been unleashing the book of destiny
across the multiverse to test different Earths.
Test them for what?
A crisis that he believes is coming.
Novu thinks the elseworlds created
by the book of destiny approximates
the collision of realities that we're facing.
Guys...
We got a situation.
Cisco.
That... that's him from the vibe.
Mar novu,
you're gonna stand down.
You're gonna use that book to help us set reality right.
Well, I certainly wouldn't have placed it
in Deegan's hands if that were my intent.
Enough.
You will not do to this Earth
what you did to mine.
I admire your persistence, Barry.
He said you were testing us.
And thus far,
I am unimpressed.
A crisis is imminent.
Someone is coming,
someone far, far more powerful than myself.
I mean to prepare.
By giving a nut bar an all-powerful
reality-rewriting book?
I am testing universes to find one, I hope,
strong enough to stand against him.
You're causing chaos,
and you're blaming everyone else!
In the hope of finding the champions
that would save the multiverse entire.
You are the first of those I've placed under fire
who have managed to retrieve the book of destiny...
For all the good it did you.
Enough of this. Kara?
Yeah. I'd love to.
You show potential.
Let us see if it's anything more.
What is he talking about, Barry?
I offered you godhood,
and you squandered it on a petty dream.
Do better.
Think bigger.
Ohh.
What the hell?
- Where'd he go? - What the hell?
He went to give Deegan the book... Back.
How do you know?
He did it again. He rewrote reality.
How far do you think
- the changes go this time? - I don't know.
- Freeze! - On the ground!
Now!
Uh... speed us out of here.
I can't. Can you?
Nope.
Oliver Queen.
I've been waiting to do this
for a long time.
Unh!
Aah!
Should I follow you? What...
Hey!
There's no place you can run where I can't find you.
It's over.
Greg, move your head.
