Watson

Previously on Watson... On two occasions now,

I've had hallucinations.

Each time, it's happened right after

I've refilled tamsulosin.

What, someone's switching out your medication?

I need to tell you something.

Dr. Watson.

Someone is watching you.

Your prescriptions come in,

and I have been trading one for the other.

You don't have to do this, mate.

I know what happened here.

He's not down there anymore. I have him now.

He's alive, Shinwell.

Moriarty is alive.

Here we go.

Another festival of misanthropy

and loneliness.

We are picking out points of genetic interest,

not living a life in the day of Stephens Croft.

You mean a day in the life of John Watson.

He's the one who spots disease everywhere he goes.

Yes, it's both a burden and privileged way

of seeing the world, Dr. Croft.

Skunk stripe.

What's the matter with you?

S-Sorry. Sir...

"Poliosis" is the medical term.

His white forelock,

absurdly blue eyes,

broad nasal root all points

to Waardenburg type 1.

Could also have congenital hearing loss.

Mm, good news, he totally heard you.

That's one point to Adam in the festival

of misanthropy and loneliness.

Dermal melanocytosis.

It's gorgeous.

And incredibly rare.

See how it runs along the lines of Blaschko? Uh-huh.

Excuse me.

I'm sorry to stop you,

but may I ask about the birthmark

that's on your back?

I run the Holmes Clinic

of Diagnostic Medicine.

You do realize that you're hot, right?

If you want my number, you can just ask.

Thank you, but it's-it's not about that.

Yeah, okay.

I'm gonna give it to you anyway.

Who are you?

John Watson.

Irene Adler.

Wha...

W-What are you doing here?

I can see what you're doing.

Out here picking up women?

Aren't you going to introduce us?

Dr. Derian,

Dr. Lubbock, Crofts.

Fellows, this is Irene Adler.

Trust her fashion advice, but do not

trust her with your Social Security numbers.

I will meet you

back at the clinic.

Irene, so I haven't seen you since...

You were attached to Sherlock's hip?

So, what are you doing in Pittsburgh?

Did you run out of yachts to lounge on,

or did some lesser-known royal kick you off?

I find the lower branches of the peerage

are lacking in vigor these days.

Almost as if there's something to all this inbreeding business.

Actually, I'm here because my son is sick.

I-I didn't know you had a son.

Angus?

John Watson, internist and geneticist.

Angus Adler, medical mystery.

So, I mean, y-you came all this way to see me?

Why didn't you just call me first?

Certain conversations are best had in person.

Knock me down with a cuckoo's feather.

I thought this was a proper establishment.

Don't tell me, Shinwell Johnson is your... receptionist?

Health-care professional.

He's actually studying to be a nurse, as a matter of fact.

Saving lives instead of taking them.

You here on health insurance fraud,

are you, or to scam

an octogenarian on his deathbed?

Those days are far behind me.

Well,

I had no idea someone had tamed

Scheme-Machine Irene.

- I pity the man. - Mother?

Hmm? Aren't receptionists supposed to be welcoming?

He's got you there, Shinwell.

This way.

Dr. Lubbock, could you please take

Irene and Angus here to the exam room?

I'll be there shortly. Course.

Hi, I'm Dr. Lubbock. It's so nice to meet you.

Come with me.

Hello.

What fresh hell is this?

She asked me to take a look at her son.

I at least want to know what brought them all this way.

Are my pupils constricting?

Yes, they are indeed.

Most kids don't know your iris is a muscle.

It controls your pupil's size.

Did you know, after you die, all your muscles relax,

so dead bodies have dilated pupils.

You're very clever.

Thank you, Doctor.

Doctors can make Angus nervous, but not you.

You must have children of your own?

No. I don't.

So, Angus, uh, need you

to stand so I can check your balance, okay?

Angus, do as Dr. Watson says.

Angus?

Angus.

Can you stand so I can check your balance?

Has he done this before?

He's often in his own world.

Angus.

Darling.

Stand up for Dr. Watson.

He called her an "old friend."

I thought it was a euphemism.

For "foe"?

Oh, you mean sex.

After last week, Watson probably could use an old friend.

Do you mean sex? Everyone means sex.

I mean he must be shaken up still. I am.

And we didn't even witness the suicide.

Do we believe

- he was just a pharmacist? - Stop staring

at the spot like it'll bring the guy back from the dead.

The problem's with the living.

After last week, I don't trust anyone

walking in off the street.

Especially not someone from Watson's past.

Did anyone ever mention to you that

Angus's staring spells could be absence seizures?

What?

I had no idea.

I feel terrible.

Don't, because those often go undiagnosed for years.

And his muscular weakness could be caused

by a number of pathologies.

His doctor back home

suspects limb-girdle muscular dystrophy, but...

He'd have to have

two mutated copies of his CAPN3 gene.

He has one.

He got it from me.

He also has

a "variant of unknown significance."

What were his father's results?

His father's no longer with us.

He was a man with many enemies, and...

...one of whom finally brought about his demise last year.

He wished to be cremated, so...

can't exactly acquire a sample.

I'm sorry for your loss.

I'm sorry for yours.

Shinwell...

You must see it.

Angus's father, he was...

Sherlock Holmes.

Everything discussed in this room

stays in this room.

Understood?

This must be so surreal for you.

You really had no idea

that Sherlock had a son?

You don't believe it's his kid.

I remain objective.

So, we have two tasks at hand.

Two teams to tackle two branching possibilities.

Adam and Sasha. Hopeful Healers.

Take the patient at face value.

Based on Angus's presenting symptoms, his labs

and his past medical records,

draw up a differential for us to discuss.

Ingrid and Stephens.

Cynic Squad.

What? Hell yeah.

Take Irene aside

and get a very detailed history.

Find out everything you can,

but keep an ear out for inconsistencies.

Whether to confirm diagnosis

or disprove paternity, we'll need Holmes's DNA.

How do we get the DNA of a dead man?

You can leave that to me.

And I need you all to remember:
