Watson

Previously on Watson...

Detective Lestrade, meet Sherlock Holmes.

-Aren't you gonna say something? -Say something to who?

There's no one there.

This is a hallucination.

I cut back on the meds I was taking, and obviously,

that was a mistake.

But you know what? As soon as I go back on them,

away you go.

Goodbye.

You good over there?

Feels like something's been going on.

Go on. Tell her.

-You're supposed to be gone. -What?

John!

Do you know who left this on my desk?

- He here yet? - No sign.

Maybe he put it here.

I mean, there's no patient information

anywhere on the scan. A cryptic message.

Seems like his wheelhouse.

Is he here yet?

Nope.

Not unless he left a CT scan on Ingrid's desk.

Scary.

A mass on the temporal lobe. I'd call it terrifying,

but if I don't know who this is, what am I supposed to do?

-Maybe he put it there? -Exactly what I was thinking.

If this is some kind of test,

I hope it doesn't take very long.

I got exactly one hour.

Lauren and I have an appointment with her OB.

Hey, Brenda, is he gonna be here soon, or...?

Where is he?

I'm just the interim receptionist.

I am not a babysitter.

If the man isn't here yet, that is his business.

Go on, make yourselves busy.

-Morning, sir. Welcome back. -Hey.

Man of the hour. Conference room's ready.

You're all here. Excellent.

You're not exactly on time, Holmes.

How can I be late if I've been working?

Been having a look at your new patient.

I didn't know we had a new patient.

Well, she doesn't know you're her doctors yet,

so everyone's on equal terms.

We'd better get started.

Loads of work to do before Watson gets back.

Regan Anson.

The streak in her hair is striking,

but incidental to our purposes.

We work with John Watson. We know about white forelocks.

Well, that's wonderful.

Miss Brenda was kind enough

to help me with this morning's presentation.

She helped me with the facts and

critiqued my grammar on occasion.

You use too many expensive words.

It's a beautiful language, Brenda. Let's revel in it.

Regan Anson was admitted to UHOP last night.

She complained of shortness of breath,

and her friends noticed a strange bronzing of her skin.

This was all before she collapsed

and hit her head on concrete.

Right now, she's sedated

until the swelling in her head improves.

Can I clarify one thing with you, Holmes?

You're not a doctor, all of a sudden, are you?

I'm a detective.

There are those that call me the world's greatest detective,

but you know, labels. I find them tiresome.

I'm sure that's exhausting for you.

Indeed.

Regan Anson, our current patient,

is tied to "Mister A."

"Mister A"? Is that a code name?

A nickname. It refers to Malcolm Anson,

Watson's chemistry teacher at secondary school.

The man changed the course of your mentor's life.

The way Sherlock tells it,

Mister A is responsible for Watson becoming a doctor.

He is responsible for Watson becoming Watson.

Surely, you've all had a teacher like that?

Mr. Topp.

-Mr. Topp. -He, um, kept me after class

and told me to stop hanging out with Andrei Plotnikov.

Mister A was that man for Watson.

Their relationship lasted well beyond his school days.

So far beyond, in fact,

that Watson asked Mister A to be his best man.

Why do they call me "Mister A"?

I guess it's because I'm such an easy grader.

That's a lie. John says you never give an A.

Yeah. Mm-mm.

I will let you all judge the truth for yourself.

But to my credit...

when John Watson

walked into my classroom,

I knew exactly what to do.

I encouraged him to apply to CMU early,

and I watched with pride

while he graduated from college at 19.

You know,

you do this job,

being a teacher,

because you hope that someone like John

might cross your path once

over the course of your career.

And that wish came true for me.

I got John,

and I saw him.

And now,

tomorrow...

I see him

married off

to someone just as impressive as he is.

To John and Mary.

A toast.

I'm sorry.

To be continued.

Please drink.

To John and Mary.

Cheers.

Mister A.

-You all right? -Sorry.

I got something from Regan when she came home from camp.

But I'm okay.

-I'm gonna finish that toast. -No, hold on, hold on.

- Let me examine you. - Oh, s-stop.

- I mean, I'd be honored, but... - I'm fine.

Let's do this.

Malcolm!

Malcolm? Malcolm?

Where is Watson?

I mean, you say he'll be back soon, but

forget the name on the door, he runs this clinic.

Where is he, and when's he getting back?

To be perfectly honest, I have no idea.

He's off somewhere. I can only assume he's thinking.

He's taking various elements

that are floating around his subconscious

and assembling those into a coherent theory.

Now, do all of you have some reason

not to let the man think?

Adam, I think you're needed in the bullpen.

- Hi. - Hey. You okay?

I think so. Maybe. I-I don't know. I-I just,

I felt weird at work, so I Ubered here, and I...

I know we have our appointment with Dr. Malena later, but

I don't feel right. You think we can head there now?

-Of course. -Okay.

The case of Mister A

was Dr. Watson's greatest unsolved mystery.

Uh... Your second boss here proposes that we have an answer

waiting for the man when he gets back.

If we solve the case of Mister A,

then I believe

we also find a cure

for whatever's plaguing his daughter.

Now, whichever one of you

makes the greatest contribution to solving this case,

you win the chance to come to England,

to take a rotation at the London Royal Hospital

for two months while studying my methods at Baker Street.

Do you have a problem with studying at Baker Street?

Studying? No problem.

Living? It just feels a little man-centric.

Potent smells.

Crusty towels.

For the record,

my towels are clean.

But you don't have to live at Baker Street to study there.

What is that leak?

Is it hot in here?

It's boiling.

Must be something wrong with the thermostat.

Someone will come along and fix it, I'm sure.

It's quite good training, when you think about it.

The temperature can be quite uneven on Baker Street.

And again, we are dubious about staying

in the Watson-Sherlock love nest.

Why are you moving that?

That's someone who's actually sick right now.

Are you sure about that?

There's no identifying information on this scan.

Could've been taken anytime.

Okay.

The famous Mister A,

he was sick all the way back in...

2010.

So, after Mister A collapsed at the rehearsal dinner,

Dr. Watson brought him to UHOP.

He was a 43-year-old man

who had recently lost almost 30 pounds,

but he still had hypertension and type 2 diabetes.

Put yourself in Watson's shoes.

It's the night before your wedding,

and the best man's just collapsed.

How would you solve the mystery of Mister A?
