Previously on Watson...
Remember Alexander Petrov, the Cobalt Fissure?
It was a three-day pursuit that ended with us surrounded
by soldiers in biohazard gear on some
weapons testing site.
I think you're sick, Sherlock.
Beck, why are you pretending to be Sasha's mother?
BECK: She cares about something, maybe she smiles a lot less.
I was hoping to have a quick word with Dr. Derian.
I gave my statement already.
Just want to review a few details.
MARY: John, you have a glioblastoma.
You're a hallucination.
You come from a traumatic brain injury I sustained
when I went over that waterfall.
-You're not there, you're dead. -You sure it's true?
So the real Sherlock is just out there somewhere?
Guv? Are you all right?
Do I know you?
John, you're sick. We are going to drive
to Baltimore to ask Dr. Niles to get on his surgical calendar.
MAN: "'Twas brillig, and the slithy toves
"Did gyre and gimble in the wabe:
"All mimsy were the borogoves,
"And the mome raths outgrabe.
"Beware the Jabberwock, my son.
"The jaws that bite,
the claws that catch."
NILES: You do realize I'm admitting you
to the hospital today?
-(phone buzzing) -No, this was just a consult.
John, your phone. Maybe...?
-You need surgery. -(phone continues buzzing)
This tumor's aggressive. It's growing fast,
and it wants you dead.
Before it does that, it's going to give you pain,
memory loss, seizures.
Listen to me.
I know you.
I know who you are.
I know what you've done.
I know what makes you you.
You have a glioblastoma.
It's bad.
If you want to come out of this still yourself,
still John Watson,
then you are in exactly the right place.
But you need to trust me.
And we need to admit you.
Tonight.
HOLMES: There were two men.
Holmes and Watson. Watson and Holmes.
And they did the most extraordinary things.
CARLIN: Are you one of those men?
Are you Sherlock Holmes?
I don't know.
There was a blue carbuncle, hidden inside a goose.
Let's assume we're not all having a mass hallucination.
Mm. That is Sherlock Holmes.
Doesn't know where he is. He doesn't know how he got here.
The man don't even know his own name,
-but that is Sherlock Holmes. -SASHA: He's in bad shape.
Dehydrated, hypotensive, fever of 102.
The triage nurse said he was stumbling when he came in,
like he was drunk.
Wernicke's encephalopathy?
Sherlock Holmes is not an alcoholic.
You don't know what he is. Not now.
-He might be malnourished. Let's get him on thiamine. -Good call.
Keep me posted.
Got to get back to Lauren, but, um...
what about Watson?
Do we tell him?
I texted the man, but no response.
SASHA: Ingrid.
How'd it go with Detective Lestrade?
INGRID: It was fine.
We talked more about my father than we talked about Beck.
Your father?
She had questions about his "sudden disappearance."
She really liked those words, "sudden disappearance."
According to Detective Lestrade,
I am a bad person to be a bad person around.
She doesn't have anything
except for questions that will never be answered.
Right, but your father, that was one thing.
Beck was self-defense.
We have a patient.
(phone chiming, buzzing)
(indistinct P.A. announcement)
MAN: "And, as in uffish thought he stood,
"The Jabberwock, with eyes of flame,
"Came whiffling through the tulgey wood,
"And burbled as it came.
"One, two. One, two.
"And through and through
"The vorpal blade went snicker-snack.
"One, two.
One, two."
(inhales slowly)
(exhales slowly)
"One, two."
-(gunshot) -(people scream)
* *
SASHA: Luna Quinn. Did anyone know her?
She's an oncology nurse.
She was an oncology nurse.
She showed me a trick to get a kid to sit still for an IV once.
So this was just random? Is this the start of something?
INGRID: Nobody knows.
They found the rooftop the guy shot from.
Every other vantage point with a view of the hospital is clear.
This is all less than two hours old.
Police will be at every entrance until we learn more.
(phones chiming)
It's Watson.
You should be in Baltimore.
I didn't hear you come in.
Thank you for treating Holmes.
But I did look at his head imaging,
and I don't think he has Wernicke's.
With respect, Watson,
I don't think you should be worrying about
that version of Sherlock Holmes.
You should be thinking about the one
that lived inside your head for months.
Respectfully, this isn't a discussion
about my condition. It's a differential.
ADAM: Who are you to say that?
You should be with Lauren.
Oh, you're gonna tell me where I'm supposed to be?
I named my son after you. I gave him your name.
-And I'm honored by that. -ADAM: Are you?
Because it seems like you couldn't care less.
It seems like, if you had an ounce of respect for us,
after all we've been through,
you'd be where you're supposed to be, in the hospital.
And you'd trust us to take care of Sherlock Holmes.
Hey. Maybe we should keep our voices down.
We have a patient who needs to rest.
I respect every single one of you.
I admire you.
If you need me to say that I love you,
I will say that, too.
But Sherlock Holmes is sick.
I'm not leaving.
You can walk out that door,
or you can help.
10% of Wernicke's patients have a normal CT.
Yes, his blood alcohol was zero, but his blood work
confirmed elevated liver enzymes.
SASHA: If we're right, the thiamine we administered will
keep this from developing into Wernicke-Korsakoff syndrome.
Either way, Sherlock is getting better.
Yeah, I'm not ruling Wernicke's out, but if he does have that,
then Sherlock's memory should be getting better by now.
So, let's order a CK, ammonia level,
a BHB, a lumbar puncture, and an MRI.
HOLMES: Hello there.
You look familiar.
Are you my doctor?
SHINWELL: All right. Here we are, guv.
(brakes squeal)
(engine turns off)
(sighs)
I'm sorry. Wh-What were you saying?
Nothing that can't wait, guv.
Actually, guv.
I do have a bit of news. Uh...
It feels wrong saying it out loud,
what with all that's happening, but...
(sighs)
I'm to be married.
-(chuckles) -What?
It's true.
As unlikely as it may seem,
that's a true fact.
(both laugh)
Look at you. Congratulations.
Carlin's lucky. You're both lucky.
-Wh-What're you doing? -Going up there with you.
Make sure there's no one lurking around the flat.
Do you think it a coincidence that Mr. Holmes just shows up
the night before that poor young woman gets gunned down?
I mean, I suppose it could be,
but you know what the great man said about coincidences.
(car door closes)
The universe isn't that lazy.
* *
It's only temporary.
You don't have to explain yourself. I'm not mad.
Not anymore, anyway.
I want to help you, John.
Before I tell everyone I'm leaving UHOP, I was
hoping to have you--
I don't know-- taken care of.
(chuckles)
Dr. Niles is still willing to work with you.
He'll even come up to Pittsburgh to do the surgery. Call him.
If that's something you want,
call him.
He looks different than I pictured him.
-Sherlock Holmes. -You saw him?
We talked for 20 minutes.
He's charming.
-There you go. -HOLMES: Thank you.
Good morning, Watson.
I understand I'm quite unwell.
Are you really just gonna linger in the doorway?
Look, I'm sorry. I just...
I-I can't believe it's you.
(both laughing)
(laughing) I can't believe you're really here.
So where have you been, Holmes?
Oh, I can't remember very much.
The falls, of course.
I know I wanted to fake my own death.
I know I went into the falls after you.
After that...
...it's all quite foggy really.
I do remember a room.
A patch of sun moving across the floor
as I worked from dawn to dusk.
Even before the falls, there's blank spots.
Whatever this is, whatever's wrong with me,
I wonder...
I wonder if it's been there for quite some time.
Will they come back?
With treatment, will my memories come back?
It's hard to say.
The electrolytes, the thiamine,
they have you stable for now, but
we don't really know what's wrong with you yet.
The doctors on my team, they suspect that it's...
it's, um, it's-it's-it's Warner's?
(distorted whooshing)
No, no, it's Verner's?
(echoing): Verner's... Verner's... Verner's...
I... I don't remember the name right now, but...
Are you sick, my friend?
No. That was just a brain fart.
And yet, you've recently been admitted to a hospital
-in Baltimore. -How'd you know that?
Not my finest deduction,
but I'm not above plucking low-hanging fruit.
Oh. This...
-So, I have a tumor in my brain. -What?
It's called a glioblastoma.
-It requires surgery. -Watson...
Listen. I'm gonna get an operation soon, very soon,
but we just have to figure out what's wrong with you first.
Would you object if I asked you a question?
No. Of course not.
Watson.
You've already taken me quite a long way.
I'm in the care of doctors hand-selected by you, my friend.
My dearest friend.
Is it me you should be looking after
or is it yourself?
NILES: This tumor is going to give you pain,
memory loss, seizures.
It's growing fast, and it wants you dead.
(vending machine beeps)
SEBASTIAN: Yes. Thank you.
(bag drops)
Voilà.
I'm sorry I'm disturbing you.
You seem to be sitting under a dark cloud.
-Do you work here? -I would love to have worked here.
My mother would've killed to have had a doctor for a son.
But school was not good to me.
The words and letters would not behave themselves.
They'd jumble in my mind.
By the time I'd worked out how to get around that,
well, certain careers were not open to me.
What is this? Who are you?
I am...
Colonel Sebastian Moran.
Yes, you've heard of me.
You worked for Moriarty. You did anything he asked you to.
Well, certain careers were not open to me.
Did you murder Luna Quinn?
I did.
Rather extravagant as an opening gambit,
but I wanted to get your attention, and I see that
I have.
You see, Sherlock Holmes has been with me.
He's not quite the same man as he used to be,
but still quite useful.
An "idiot savant,"
I think you call it, since he wandered back to London.
What have you been doing with him?
Solving problems.
There's been quite a power vacuum
since our dear leader, Professor Moriarty,
shuffled off this mortal coil,
in your establishment.
Your Mr. Holmes, recently, he's been sicker, more addled.
Not quite so useful.
You brought Sherlock here.
I did. I want him patched up,
and then, I want him back.
So, your problem's gonna have to take a back seat for the moment.
That's not gonna happen.
My symptoms, they... they've been getting bad.
Gonna have to manage
because the stakes are higher than you think.
Now, do not do anything rash.
Do not grab your phone when I leave this room.
We have eyes on Dr. Morstan at this very moment.
So, your choice is not between your life and Sherlock's.
It's between Sherlock's life and hers.
-I'm not going anywhere. -Mary, you don't understand.
Sebastian Moran killed Luna Quinn yesterday.
-So we bring in the police. -We can't do that. Not yet.
Moran is not alone on this.
I need to work with Sherlock to figure out where his people are.
The only way that you are gonna be safe
is if we get them all at once.
This is still my hospital, John.
One of our nurses was gunned down yesterday.
I am not hiding. I am not running.
-Mary... -Oh, it's frustrating, isn't it?
Someone you care about, refusing your advice
about how to stay safe?
(distorted whooshing)
SASHA: Watson? Are you okay?
Yeah, I'm-I'm here. I'm fine. I'm-I'm here.
Did I write that?
Sorry. Obviously, it was me.
All of these-these symptoms,
they're behaving like CTX.
But that's impossible. CTX is genetic.
If Sherlock had it, he would've had symptoms his whole life.
I'm aware of that. It's acting like CTX.
It can't be CTX. So what is it?
I still think it could be Wernicke.
Maybe, but he's showing white-matter
T2/FLAIR hyperintensities.
Look at his MRI.
(sighs)
If they are lesions, they're near the ventricles.
I'd say MS, but there's no Dawson's finger pattern.
It's too symmetric.
-Atypical MS. -That tracks. That could be it.
Put him on methylprednisolone.
And if we are right, if this is in fact atypical MS,
Holmes should improve quickly.
INGRID: You're reviewing the blood samples?
We have a diagnosis. Atypical MS.
SASHA: A tentative diagnosis.
We've been doing this for a while.
It's always good to have a backup theory.
You're smiling?
Everyone signed off.
I'm back in my therapy group.
Congratulations. I'm happy for you.
You're not smiling.
(sighs) I'm just a little busy.
I don't mean right now. I mean, in general.
You're still not smiling.
What is this?
That's everything I learned about your mother.
Your birth mother.
She's real, Sasha.
Her name is actually Shun Yi.
She might not have reached out to you,
but she's right there,
if you want to take a chance.
(crying) Thank you.
I appreciate this.
(indistinct P.A. announcement)
WATSON: You okay?
Been worried about you, Shinwell.
I know who Sebastian Moran is to you.
I know what he did.
It's academic anyway, innit?
I ain't got the foggiest idea where Moran is.
Sebastian Moran?
If it's Moran you're looking for,
X marks the spot.
You'll feel better soon, guv.
I'll thank you not to condescend to me, Shinwell Johnson.
Sebastian Moran has dyslexia.
Yeah, he pretty much told me that.
It led the world to underestimate the man,
so keen mind that he is,
Moran developed a work-around.
Certain letter pairs are confusing
to someone with that condition.
P and Q. M and W.
Moran's solution was to replace those letters with an X.
Work out the sounds around them,
and then make the right choice using context.
How do you know that?
HOLMES: Because the man has a tell.
He gravitates toward the letter that makes him feel safe.
The letter X shows up in Moran's speech,
and his writing, far more than is typical.
Far more than he realizes.
If Moran is operating here,
then he's staying here.
If he's staying here,
he's using an assumed name.
A name
that probably has at least, what, two Xs in it, right?
Shinwell, call Detective Lestrade. Tell her to check
-the guest lists at all the hotels. -(monitor beeping)
SHINWELL: What's happened?
WATSON: Sherlock?
SHINWELL: His heart just stopped.
(monitor flatlining)
No pulse. Start the compressions.
(alarm ringing)
Code Blue! We have a Code Blue!
-Status? -One minute down, no change.
CARLIN: Clear.
-(thumps) -(monitor beeps)
He's still in V-fib. Again.
Charging.
Clear.
-(thumps) -(monitor beeps)
(gasps)
We've got him.
Let's keep him stabilized and get a full cardiac panel.
Where's John?
Anyone see where Dr. Watson went?
Guv?
Where'd you get...
Ah, John. Help!
Dr. Watson's down!
Come on, we need help now!
-SHINWELL: We need help now! -(groaning, straining)
Keep his head protected. Shoulders only.
MARY: I need everybody to stay back.
What's the duration of the seizure so far?
I don't know. Three, four minutes?
I lost sight of him.
We need buccal midazolam.
Top drawer of the crash cart.
Hurry.
I've got you, John.
Can you hear me?
-I've got you. -Mary.
(sighs)
SHINWELL: There's nothing.
-There's no change. No, it's not stopping. -Give it a second.
Just give it a second.
His seizure's stopped.
Your EEG. It's nightmare fuel.
Dr. Derian.
How long have you been sitting there?
You're having prolonged cortical discharges.
Your brain is firing like it's stuck in a loop.
How's Sherlock?
I'm not here to talk about Sherlock Holmes.
He's not great.
His angio confirms premature atherosclerosis.
He has narrow vessels,
even though he has an optimal lipid profile.
He's also fighting for breath.
Atypical MS shouldn't cause heart attacks.
Are you listening to me?
Are you finally, maybe listening to me, even just a little bit?
You just had a tonic-clonic seizure.
And it won't be the last one.
Your best case scenario is more seizures just like that one,
wherever and whenever your brain finds it convenient.
I know you're aware of the worst case.
-Status epilepticus. -That's right.
You're in danger of having a seizure that doesn't stop.
It's often fatal.
And even if it isn't, a seizure like that
carves out more and more of you the longer it goes on.
Language. Memory.
Everything that makes you you.
Dr. Watson.
John.
You mean something to me.
You gave me a place in this awful...
...beautiful world,
and if I have to visit you at a long-term care facility,
every day, forever,
I'll do it.
But please...
Please, don't make me.
CARLIN: You did good.
With the seizure.
Good job.
We got a clue.
Before everything blew up,
Mr. Holmes gave us a clue
about where we can find the man
that shot Luna Quinn.
That's good.
I'm sure the police are really grateful
to have any help they can get.
That's what Dr. Watson said.
Tell the police.
-Did you? -This man...
The man that killed Nurse Quinn.
He owes me a debt.
I asked you to marry me
because you told me
that the man who went collecting on debts like that was dead.
You promised me.
So I did.
You can still call Lestrade.
You could do it right now.
(Holmes breathing heavily)
Watson?
You've come back.
They told me you had a seizure.
I did.
Good God, man. The pair of us.
We're crumbling like an old Saxon fort.
Will it be morning soon?
Yeah, the sun will be coming up any minute now.
I wouldn't mind catching a glimpse of that.
Don't know if I have another sunrise in me, my friend.
ADAM: Lauren's hand cream.
Vegan what-have-you snacks.
Yes. My AirPods.
You are the man.
Stephens?
Sorry.
I got caught up just... staring.
They are amazing, aren't they?
Stephens.
Did our father kill himself?
I didn't even know you wondered about that.
Yeah, I think he did.
I think he did, too.
I want you to promise me something.
If that's ever you,
tell me you'll stop.
Tell me you'll call me.
You're my brother.
You're my twin.
I can't lose you.
Can I tell you something?
I'm not worried about that.
Not anymore.
I can see...
I don't know, call it a future?
I'm gonna be alive.
I'm gonna have a life.
You already do.
HOLMES: I was promised sunlight. This is just...
-cold and murk. -(scoffs) Oh, please.
-We've sat through much worse. -(chuckles)
I like this place.
What I can see of it.
WATSON: It was right down there,
my mother used to work at that museum.
There's a library right next to it.
Well, actually, they're attached,
if you can find the right hallways.
I'd walk there after school, wait till she finished work.
Must've read half the books in that place.
Time well invested.
What a lucky thing for your city.
Lucky thing for all of us.
What are you thinking about?
The Cobalt Fissure. It's odd.
We both chased Alexander Petrov across that blasted heath.
We both absorbed whatever radiation
was lingering from that weapons site, and yet,
you have a brain tumor.
And I got away scot-free.
This your idea of scot-free?
This is something else.
We both got sick,
but we didn't get sick together.
...but we didn't get sick together.
Ah. Look at that.
Creation itself.
A passion play,
staged anew every morning.
I'm sorry. I was thinking about something.
Holmes, that cloth that you're using
to wipe the sweat from your fever.
Can I borrow it?
(fizzing)
(laughing)
(sighs)
* *
(distorted whooshing)
*
(indistinct P.A. announcement)
SASHA: It happened.
The seizure that never stops.
Watson's in a coma?
Not exactly.
The medications, they mimic that kind of state.
We'll wean him gradually,
see if the seizure activity has stopped.
And if it doesn't?
Even if the seizures do stop,
who's to say what's left in there?
(door opens)
(door closes)
Alexander Knox.
'Twas the Xs that done give you away.
SEBASTIAN: Ah.
-Well done there. -Yeah, don't bother.
I've swept for weapons.
The only thing you're gonna find stashed there
is overpriced bourbon.
Fair enough.
And why is it that you are here and not the police?
You know why.
Luna Quinn.
Nancy and William Evans.
Countless others.
Ms. Quinn was unfortunate, but necessary.
As for the old couple, what makes you think they're dead?
Ah, I don't know.
Maybe the blood splattered on the walls of their flat,
the scene of the slaughter.
Stagecraft.
Why would I give up such a piece of leverage
with someone like yourself?
The Evanses are fine and dandy,
but you have done well to track me down to here.
I cannot let you go empty-handed.
I will give you my Lieutenants Maitland and Ort.
One of them is very close to Dr. Morstan as we speak.
Those men trust you.
But we are all of us alone in the end, Shinwell.
You know that.
And congratulations.
You're engaged.
The odd couple,
but quite suited in the end.
So what is it?
I'm to be beaten to a bloody pulp
for a couple of murders that may not have happened,
or you hand me over to the police,
and then, they definitely will happen.
Or you let me leave.
Go back to the life you were living.
Untainted by violence.
HOLMES: Squeeze my hand if you can hear me.
Squeeze my hand if you're Watson.
(chuckles) Excellent.
You may notice I'm looking better.
Well, your team found the results of your experiment.
The one you were working on when you collapsed.
You trained them well, my friend,
because they filled in the blanks perfectly.
CTX.
(chuckles) You needn't crush my hand, John.
I'm aware it's a CTX phenocopy mimic.
Seems I'm a mutant.
My genes altered by the radiation of the Cobalt Fissure.
All my symptoms-- the, uh, confusion, the heart attack,
the blindness--
they came from a cholesterol-like buildup.
So, they're administering something called, um...
Well, there's not many words I won't attempt,
but your young doctors managed to find one.
And I must say, it's worked a treat.
We did get sick at the same time, my friend.
The radiation that caused your tumor altered my genes.
Alike, even in illness,
Holmes and Watson.
(elevator bell dings)
Two conspirators arrested.
Moran is in custody.
What is that?
(sighs)
I knocked out four of Moran's teeth.
When I got to his molars,
he told me what I needed to hear,
the location of William and Nancy Evans.
And yeah.
Yeah, I wanted to carry on.
Good God, I wanted to carry on.
But I didn't.
I called Detective Lestrade and told her where to find Moran.
No one was damaged beyond repair.
It's just...
I...
I can't lose this.
I can't.
If there's still a home here for me then...
...then I had to come home.
SASHA: Hey.
Usually, you find me at my desk when you want to talk.
I know. I like it here.
I want to try.
I'm so sorry I didn't hear you when you tried to bring up kids.
But I hear you now.
And I want it, too.
I want that and
whatever that means for you.
If that means a big day,
300 people in ball gowns and tuxes,
that ceremony that you've had in your head
ever since you were nine years old,
I want to give that to you.
Hmm.
I'm not sure how much I trust the things in my head right now.
Are you talking about Beck? Because that was just a blip.
In the course of your life, it's just a thing that happened.
It doesn't have to change anything.
I'm an optimistic person.
I put out into the world exactly what I want it to be.
-And I love that about you. -Yeah, but I've...
I've been a bit of a fool.
For a good while now.
I need to change some things.
I don't know how I'm supposed to be in the world.
I don't know who I am.
And if I don't know who I am,
how am I supposed to know who to be with?
Stephens, I'm happy you know what you want right now.
It just shouldn't be with me.
(crying)
Good morning, Dr. Derian.
I already answered your questions.
I'm not here to ask any questions.
I'm here to show you something.
Did you know Beck Wythe kept a hidden camera in his condo?
Took us a minute to find it, but it turns out,
it was running the night you stopped by.
I don't want to watch this.
He must've known you were interested in that laptop.
So, the events in question.
They're all right there.
That's it.
That's exactly how I told you it happened.
Is it?
You had Beck's laptop.
You had the evidence you needed,
but then you put it down and went back to him.
Why?
I already told you what happened. It was self-defense.
And if it was something else,
which it wasn't, who cares?
You're talking about Beck Wythe.
He hurt people. He killed people.
Are you putting me up for a commendation?
Because if not, what are we doing here?
Oh, honey.
I think someone's called you special one too many times.
I know he hurt your friend,
but we don't give out hall passes for murder in this city.
I have an appointment.
Sorry I'm late. Got hung up.
FERRY: We're just getting started. Have a seat.
Since you're back with us again this morning, Ingrid,
I thought maybe you could get us started.
I'm Ingrid Derian,
and I have antisocial personality disorder.
SHINWELL: I know you're still weak.
I know you can't talk yet, but I just...
I wanted to say good luck, guv.
I love you, too, Watson.
You kind of snuck it in there, didn't you?
But I caught it.
We all did.
Thank you. For all of it.
For everything.
I'll be waiting for you, Watson. We all will.
(crying)
My entire world changed the day I met you.
Every plan. Every dream.
It all shifted that exact second.
(sniffles) How could it not?
I had to make space for you.
I am in that operating room with you, John.
Every room you walk into, ever,
I'm there.
WATSON (weakly): Do you remember...
...that day in your conference room?
You were kissing Josh,
and I walked in on that.
Do you remember?
("Fearless" by Pink Floyd playing)
I was there to say,
"I love you."
I have this picture of you and me.
And we're living on Baker Street in London.
We're having breakfast.
But we're not talking
'cause we don't need to talk.
We have everything we need.
I love that picture.
That's a nice picture.
(crying)
You are going to be okay, John.
You have to be because...
I can't imagine a world without you.
(sniffles)

* You say the hill's too steep to climb *
* Chiding *
* You pick the place and I'll choose the time *
* Go down in your own way *
NILES: Ready for the primary incision.
* And every day *
* Is the right day *
* And as you rise above *
* The fear lines in his brow *
* You look down *
* Hear the sound *
* Of the faces in the crowd. *
You're home early.
