Original subtitles

Previously on Watson.

Five years sober as major.

He started rehab sophomore year of college.

Never relapsed.

What you said about me last week, you have no idea who I am. I didn't label

I said you lie often and casually.

I told you something last week about my dad.

My interpretation is that you killed your father.

You played the sacred ground.

Why would this be sacred ground?

Well, you tell me, Ingrid.

He's not down there anymore.

I have him now.

So you're collecting DNA?

Professor Moriarty would like similar specimens from each of the fellows at

clinic. He gave us fake DNA samples.

He says no mistake this time.

The patient's been asleep for 14 hours and counting this time.

There's no mystery here.

I will bet you all $100 this is Kline -Levin syndrome.

Mike Dwyer is in his 30s. That's late for Kline -Levin. Unless there's a

like this change of dress form.

Cajun's only been in his current dress for two months.

That's when he started sleeping all the time.

Cross, what do you see at that location?

Basement of his building is a shared laundry room.

There's a sub -basement.

Looks like an old bomb shelter.

Doesn't look like anyone's been down here for quite some time.

Look at this.

That's black mold. Put your mask on.

Nightwire is living on top of a thriving colony of black mold.

Black mold contamination.

We'll monitor the patient while his body expels the spores, and we'll give him a

letter for mold remediation once he wakes up.

Mystery solved.

I have plenty of time to wash the mold off before dinner.

This is my fifth date with Nell.

Don't embarrass me.

When you're a kid with a twin, your friends just want to know one thing.

If it came down to it, could you pass?

Same outfit, same hairstyle.

Could I pass for Steven? Could the Stevens pass for me? Oh, I could answer

one.

Absolutely not.

You sound so confident.

I've dated both of you. Who's more qualified to weigh in here than me?

So you're saying there's no way?

It's got nothing to do with clothes. It's an energy thing.

You're Adam. You're Stevens.

Never the Twain showmate.

I'm so sorry. I forgot to ask. Can I see a list of your mock tips?

Of course, sir. Thank you. We hated that question.

I did everything I could to set myself apart from Adam.

Unless, of course, it was Halloween.

Oh, what happened on Halloween?

On Halloween, we leaned into it. They wore the same costume.

I disappeared into Stephen's, and Stephen's disappeared into me, and on

night, we were one.

Oh, sorry. Maybe you fooled eighth graders, but guess what?

Eighth graders are dumb.

Well, you fooled everybody.

I got Adam grounded one year because our own mother couldn't tell who was who.

Honestly, if we could pull it off right now, I could be Adam for all you know.

I hope you're not Adam.

When you're a kid with a twin, your friends just want to know if you can

You just said that, babe.

Is this part of the story?

Right?

Sorry.

So it's not the same as dating twins, but my friend Joy from New York...

Surprise, mate.

Anybody got any kisses?

There's no plastic tarp on the floor. We're not getting whacked.

He didn't tell you either, huh?

Dr. Morstan.

Wow, Watson invited you too?

I resisted the urge to bring an attorney.

No, there's no cause for a lawyer because we're here to celebrate.

The Holmes Clinic attracts people from all over the world. As you all know,

almost every patient that comes through here donates a DNA sample. A consensual,

anonymous contribution to the world's body of knowledge.

We're not just helping people.

We're building a library.

I have been working on a project to put that rare DNA we collect to

use for the good of the species.

A Watson database of human mutations. It's my last work. It's our last work.

There's going to be an article in the New Scientist next week. This clinic is

the hub for a project cataloging every mutation known to mankind.

So once that paper comes out, this place is going to be a magnet for mutations

from all over the world.

It's going to be very busy in here.

Shimwell's going to need some help.

Anyone heard from Shimwell? The man's never missed a day of work.

We're all listed as authors.

We share the work.

We should share the credit.

Excuse me.

Can I help you with something?

Um, sorry to interrupt.

I've been having migraines, and my ENT said maybe I should come here for a

second opinion.

I'm sorry, we don't take walk -ins here.

I'll see him.

If he's having headaches, we can't let him walk out of here without a neuro

workup. It could blow back on us.

Okay.

This place is awesome.

Thank you.

What do you want? Relax.

I'm here to set you free.

What does that mean, don't talk in riddles?

Dr. Watson curates a cutting -edge genetic slab at 20 feet from here.

I'm sure he's growing some adeno -associated virus for his experiments.

That's a viral vector. I know what adeno -associated virus is. Good.

All you have to do is find the sample he's growing.

Pour the contents of these packets into each and every culture dish.

You want me to sabotage Watson's research.

Why? Just do it for me, and then you're free.

I don't believe you.

There's no way that's the only thing you want me to do.

This place has got you confused, Ingrid.

You were born to be a certain kind of person, and you're fighting that.

You can be who you are.

Is this the last thing I'll ask you to do? Of course not.

But everything after this will be easy.

Are you him?

Are you James Moriarty?

Of course I am.

Dr. Watson thinks my fingers are webbed.

It's all just sleight of hand, really.

If a geneticist is chasing you, show him syndactyly. Direct his eye where you

want it to go.

is so I could introduce you to yourself.

Have you seen your brother?

Uh, no, he's not back from lunch yet. Why?

I just got a very strange phone call from the nurse's station on 6.

Can I have my purse back?

Dr. Croft.

Adam, what the hell are you doing? He picked up my bag and just started

through it. What is the matter with you? I'm not done, Adam.

Dr. Croft!

I need to take this, okay?

Listen, we're going to get a room ready for you. You can rest there.

I was looking at that. I understand.

Are we okay?

We need to admit Dr. Croft.

Be gentle, but I want you to check his vitals and... Take his blood and urine

for a tox screen.

A tox screen?

Adam's been in supper for five years. Looking at the same picture, right?

Obviously, this is strange, but Adam was exposed to black mold yesterday. We

were going to consider everything, but we can't ignore the obvious.

After a tox screen.

We have to consider the possibility that Adam is having a relapse.

How's the weather over there?

I can tell when things are cloudy in your head.

Are you okay?

I'm fine.

Thanks.

I'm angry.

What's going on?

I need everyone in the conference room. We have a new patient.

My brother needs help.

What's wrong with Adam?

Is he behind?

No. Adam is sober.

He has a history of addiction.

He's experiencing short -term memory loss, lowered inhibition. We can't

relapse. I have a diagnosis for Adam. He's annoying, and I say that with all

love and respect.

Can you call someone annoying respectfully?

If he's your identical twin, yes, you absolutely can.

Look, my brother takes recovery very seriously.

I don't believe that he's high, but Adam has already given blood and urine for a

tox screen.

It'll show what it shows, but I don't want to sit around waiting.

Are you looking at me?

Your colleague has a conviction.

You said Adam was exposed to toxic mold yesterday?

I mean, who knows what else was in that bunker. Sounds like a mycotoxic

playground.

What did Adam eat last night?

Some sort of overpriced, pretentious vegan mush.

Definitely looked capable of causing illness.

With your permission, here's what I propose.

Dr. Croft, you head back to the sub -basement.

Take pictures and catalog anything that could account for Adam's symptoms.

Sasha, you can see what you can learn from the restaurant, and you can help

Stevens.

Ingrid, you can supervise Adam's tests, rule out trauma, stroke, or any other

lesions. If the tox screen comes back negative, then we'll have a head start.

Sound good?

Thank you.

Your brother's lucky to have you.

a bandage on my arm. You drew blood.

Watson's running a tox screen. What?

It's a precaution. A precaution? That's good.

We're not waiting around.

We'll figure this out.

It's gonna come back positive.

What? Tox screen. It's gonna come back positive for hydrocodone.

Lauren had her wisdom teeth out.

She had a prescription for it.

She was traveling last weekend.

Lauren forgot it was there. I forgot it was there until I went looking for

toothpaste. I had a weekend to myself.

I took six pills over two days.

It was a relapse, Stevens.

You're getting engaged.

You have a book coming out. Why?

Because I have a book coming out.

Because I'm getting engaged.

This addiction, there's no logic.

Stevens,

it's Wednesday.

I took the last pill Sunday morning.

I'm going to test positive, but I wasn't high this morning. I don't know what's

going on.

Should I tell Watson now?

No, no, no way.

We still have a few hours to figure this out. I want to know what's happening

before the results land so no one thinks that you're high at work.

a mistake.

We'll deal with it, Adam.

Thank you.

Seriously.

I'm sorry I wouldn't talk to you before.

I was scared.

Okay, how was the headache?

Oh, I'm feeling great. Thanks for asking.

That doctor was very generous with their time. I'm grateful. Okay, good, good.

It would feel so good to tell you all about it, Sasha.

But here's the thing.

We all have a circle of people we're looking out for.

They can only get so big.

I'm taking care of me and my sister.

It's enough.

If I'm not careful, if I let it grow, soon I'm taking care of everyone.

And that's the same as taking care of no one at all.

I, um, wasn't trying to eavesdrop. I guess I walked in at just the right

But what you're doing at your clinic sounds incredible.

A database of human mutations.

Wow.

Overheard of her. Enough to be impressed.

But don't be nervous. I'll never tell.

You're a good person.

You haven't had to learn the things I've learned yet.

Um, thank you for what you're doing for all of us.

We'll probably never meet again, but... I'm a big fan.

It was fun to picture a different version of me.

Christina, you're real.

John, did you learn anything about Adam?

Not yet. We're still working a few different angles.

I have to be the first one to see his toxin.

He's a doctor in my hospital. I have to know if he's high.

I'm sorry, John. He tested positive for opiates.

We'll test again.

Keep looking for anything that might help.

But with what I'm seeing right now, I have to treat this as a case of

intoxication. I should tell Stevens before we do anything.

He's going to take this hard.

This is Watson.

Be gentle. We're on our way.

Dr. Cross just wandered into the operating room.

Okay, that is a dangerous tool. I need you to put that down. Come on, it's all

right. Put it down.

I need you to put that down.

Adam. That is a dangerous tool. We were prepping the OR when he came in. It's

like he can barely hear us.

He needs to get that back to us.

Stevie?

What are you doing?

Have you seen this thing?

Absolutely incredible.

All right.

Okay. Let's give that a rest.

Okay.

There we go.

Now that they're both presenting with the same symptoms, we have to reconsider

everything we thought we had observed.

Dr. Darien, what do you think?

Hyperanamorphosis. That's why they're losing their minds about everything.

Extensive attentiveness to visual stimuli with a tendency to touch each

stimulus.

You think he'd never seen a mug before.

Or he doesn't know he has visual agnosia.

Yes, Dr. Marston.

Their eyes were working.

but their brains aren't processing what they're seeing.

We witness all of these symptoms.

Plus this association.

We're disassociated during these episodes.

And then suddenly Lou's dedicated him back to their bickering selves.

Oh, something's happening.

Dr. Croft, you can't be certain. Don't put that in your mouth.

Doctor, please.

Where'd they get all this?

They pulled a meal cart in from the hall.

And then the collection cart?

They're eating other patients' leftovers?

Hypophasia, insatiable eating.

Book the MRI, Dad.

We just had MRIs. I know.

For the results to be different, their brains would have to be changing

I know, Ingrid. I need you to move fast.

Book the MRI.

You were right. They changed.

In four hours, their temporal lobes changed.

These angry -looking signal abnormalities.

Exactly.

PICA coexists with across other symptoms. There's just one diagnosis.

Kluver -Bucey syndrome.

What's the prognosis?

Cat's getting brain damage unless the underlying cause is treated.

It's fatal?

Stay here. Underlying cause.

Neurosyphilis, meningitis, stroke.

Syphilis and meningitis tests are all negative.

Pick's disease, West Nile, tumor.

We can likely rule out twin tumors. You both are missing one major cause.

Herpes simplex encephalitis.

Adam did have a cold sore. Well, rarely the virus can ascend to the brain via

the bloodstream or nerve.

No one actually knows how.

So Adam passed it to Steven.

You know, I've seen them both drink out of that mug. They'll never admit it, but

they're both dying to be number one.

Maybe that's why I've never seen either one of them wash it.

So it's good news.

How did you hear Clover Beauty can run with good news?

That's a serious diagnosis, but of all the root conditions, herpes simplex is

one of the most treatable.

Two weeks of antivirals, and you both should be back on the road to recovery.

Thank you, Watson, for figuring it out. If he did.

Laura's been in the waiting room all day and all night.

I'll update her and hopefully we can get you all home as soon as possible.

Can't wait.

Aren't you worried about her?

I am.

But the treatment should help.

We're not that alike, are we?

You and me.

I can't tell if I should be more like you or if that's the last thing that I

would ever want to be.

Be you.

I can't do it.

Hi.

I still know Shinwell.

I thought he was with you.

How did you get here?

An Uber that smelled like burritos and cigarettes.

I'm starting to worry about Shinwell.

Not to add to your concern when you're barely through the door, but the crafts

aren't responding to the antivirals. Have you had a course of

Corticosteroids and Foscarinib.

And with all that, somehow their viral load is increasing.

They're positive for the herpes virus, but it's antiviral and steroid

Makes no sense.

Add to that how rare it is for the virus to cross the blood -brain barrier in

the first place.

And it happened to both of them.

Something's really off here.

I need you to sequence a sample of the virus itself.

On it. I'm going to call in a welfare check on Shinwell.

I don't like the timing of this.

I have a bag of escalogen.

They're officially throwing spaghetti against the wall.

That negativity isn't helpful.

Neither is the fallacy of positive thinking.

Our episodes are getting longer.

Harder to bounce back from.

None of the treatments are working.

Not accepting the reality of the situation isn't heroic.

Idiotic. You're the one who's idiotic.

I see your disambition has returned. Why don't you get it all off your chest?

You are the twin who is objectively smarter and better in so many ways, yet

people always choose me over you.

Do you know why?

Because they suck at multiple choice.

Because life is one nightmare after another, and the situation that we're in

right now is a perfect example. And in the depths of a nightmare, who would you

rather be around?

Is the answer you?

Someone who makes you feel better or someone who guaranteed time after time

makes you feel worse.

What does it matter what you feel if you're still stuck in a nightmare?

It changes how you survive it.

I have a hard enough time getting out of the darkness without you dragging me

back in.

Hope isn't...

Idiotic, Stephens.

For most of us, it's necessary for survival.

The results are in.

Look at this.

At the top, it's standard herpes virus.

Bottom is the cough.

That doesn't look like something that occurs in nature. It's not.

It's been genetically modified.

Someone made this virus.

Who?

You, Gov.

You made this virus.

We did.

What?

Where have you been?

There's a lot that's been needing explanation, so I've been off trying to

all down, pen to paper.

But I knew I owed you a conversation.

But less the chance of spitting me, folks.

Your research made the Crofts sick.

It's Mariarty.

You were right.

But he's, uh... Culling all black bargaining, he survived the trip over to

Waterfall.

And I've been doing as he asks for months now.

The man has his hand in your life's work.

Every entry in the database of human mutations, he has it, same as we have.

Adam Croft overheard something he shouldn't have.

Yeah, it's nothing.

Forgotten about as soon as I spoke it aloud, but Moriarty is not one to leave

thread, honestly.

I believe Adam's the target here.

Stephens, he shares the same DNA, doesn't he? So he's just collateral

I don't know how he does it, Dove, but you'd be the one to tell me.

All that DNA you're keeping downstairs, Moriarty knows how to turn it against

people.

John, I made you a size something here.

Anything.

All this time.

With me.

With Holmes.

That was a lie.

Far from it.

You and Mr. Holmes showed me a better way to live. Then why?

And there are those that... loved me along

the way.

Moriarty intends to kill them both, if he hasn't already.

John, I need you to tell me how you want this to go.

Tell me to help.

Tell me to lay down my life in service of the cross, cos I'll do that.

Tell me to turn myself in.

Let's tell me.

I'll let you know.

So there.

The whole story.

Yeah. Give him a minute. Yeah.

He'll be down soon enough.

Everything all right, Shamwell?

It's been my privilege.

It's a good place you got here.

Uh -oh.

You're all in danger.

Safest thing for everyone in this room to do is to tender your resignation and

go home.

Why are you saying that?

The DNA that we've been collecting, the work that was supposed to change

everything, it's in the hands of someone evil.

It's a weapon now.

And that weapon has been turned against Stevens and Adam.

And it can be turned against any one of us.

A man named James Moriarty has your DNA.

He has everyone's.

And he can use it to kill you.

Anything you breathe in, anything you touch could be a vector. It could carry

designer pathogen made to end your life.

I thought that we were building something to help everyone.

But really, we are just a factory.

We mass -produced murder.

Stevens and Adam are dying.

You want us to leave you to help them by yourself?

I want you to make an informed choice.

I'm not going anywhere.

Neither am I.

All right.

I don't know what's next.

I don't have any orders to give, but if you're going to be here with me, we're

going to figure this out together.

Well, we worked.

While you were upstairs, it worked.

We brainstormed genetic conditions that could be magnifying the effects of the

virus. Then, we took our database and ran the cross -CNA through that filter,

expecting to see something affecting their immune system.

Instead, we found this.

A SNORA A31 mutation.

A mutation on this gene basically destroys the body's ability to... Keep

out of the brain, Jess.

Occurs roughly 0 .001 % of the population.

Dr. Lubbock, Dr. Darian, you have found a needle in a haystack.

Two people with a mutation this rare getting hit by an unkillable version of

their own kryptonite.

It is statistically impossible.

You were right.

This was made for Stevens and Adam.

Exactly.

Dr. Morrison, you fired me.

You found out what I did for my sister and you tried to force me out.

If I stay here,

I'm going to go fired.

I'm sorry, are you negotiating?

Dr. Darian, in light of circumstances, I'll move you to probationary status.

Any suspect behavior and you're terminated.

Okay, look, you're all here now, and I will never stop being grateful.

But now let's find a way to kill the unkillable.

There you are.

It's... What is this? What's happening to us?

They're on top of it.

You know, if anyone can fix this. Fix this?

What happens if they can't?

Adam, we don't know.

If you're about to attempt encouragement and optimism, please spare us both from

that train wreck.

I got smug, Stevens.

All those years of meditation.

Then metaphysical and spiritual.

Here I am still just terrified.

And again, it's not the time to have a mid -territory routine.

Not mid -territory.

No one knows what's on the other side.

Or if there is another side.

I don't think that there is.

Yeah, definitely not, Mr. Rogers. That doesn't mean we just end.

What's the first law of thermodynamics?

It's the law of physics and undergrad.

Energy cannot be created or destroyed. It can't go poof. It can only take

another form.

Miss John?

I've seen people die.

I don't need to believe in Deepak Chopra or Santa to know that in that moment

something, God's energy, leaves the body.

And in my bones, I know that that energy doesn't disappear into the

void, just as I know that water in a puddle doesn't, despite comparing my

to a puddle.

I'm scared too.

But I don't think we just end.

The body, the consciousness, the bells and whistles, sure.

But the engine at the heart of it, the heart beneath the heart,

whatever it is that really makes this whole thing tick.

EEG tech in here? What's going on?

We won't know until we run the EEG.

Lana.

Adam's fallen into a coma.

Dr. Lubbock.

Violation of PPE protocol, no less.

Well, I'm a Texas scout, the rebel soul.

And y 'all ain't catching.

Lauren dropped these off for y 'all.

Here's one for me.

Thank you, Dr. Lubbock. I'll read Adam's letter to him.

I should, I should get back.

I always... Assuming that we'd have plenty of time.

Yeah.

Me and you.

To be here.

To become whatever we were going to be.

Not that I was making any assumptions.

I just hoped we'd find the right moment.

Me too.

This is the right moment.

It's not the one I imagined.

I figured it would involve candlelight or sunset or

at least a ferris wheel.

One moment.

I will take it.

Through here.

Have you been here all night?

Get a load of that fella.

Hide in the neurons so we can't get to him. So we'll need to offset for

hepatotoxicity.

Last one scientist used a meganucleic enzyme to cut this.

virus out of healthy brain cells.

Often this is encouraging, but they've only done this once in lab mass.

We're inventing a new cure here, Dr. Lubbock.

There's not going to be a lot of precedent.

Okay, so how do we get the enzyme to the virus?

Drill it to the skull, obviously.

Obviously. And from there, this guy should take us exactly where we need to

What is that?

Tiny scissors.

Tiny scissors.

Oh, yeah, tiny scissors.

It's a wave.

No, it's a viral vector I've been tinkering with for gene editing.

This is our delivery system for the enzyme.

It goes after all the neural viruses, and the accuracy is deadly. Guess which

enzyme it carries inside.

This could work.

This could work. This could actually work.

Oh, yeah, you bet it could.

Oh, no, tell Stevens.

I'm sorry.

Understood.

Understood.

You have my word.

Listen, you don't heal.

You don't move.

It's a procedure to save the crops.

Now, it's untested, and it's dangerous.

If something goes wrong... Do it. Meredith, it could blow back on the

and it could blow back on you. Just do it, John.

Save them.

I got you.

Great, thank you.

Dr. Doherty said he's ready to draw some skulls. I'll do the surgery.

I knew he'd want a shot at the record books.

The next available OR flattened at 1 ,300. Take it.

Put it in.

Dr. Lubbock, prepare a saline bait.

On it. Dr. Darian, dose us up. Target seven micrograms of our tiny fizzers per

unit. Where are the cultures?

In the incubator, base level.

Everything okay? Those are adeno -associated virus. I thought you called

wave nine. Yes, Watson adeno -associated viruses, type nine.

Wave nine for short.

My coach is Dr. Darien.

What's going on?

It's dead.

It's also dead.

Okay, well, I'll call around. Another lab's got to have it. No, I made these.

one else will have them.

Okay, then we grow more. It's going to take weeks. The crops will be long gone

by then.

We see another one.

Also dead.

Ain't too bad it was turned on. It has to be.

I centrifuge everything that was left in the culture dishes.

That gives us a usable amount of vector.

Wait.

Seriously?

What?

There's only enough for one dose.

We can save Stevens.

We can save Adam.

Stay tuned for scenes from our next episode.
