HOLLIS: If you watched my mother's life...
(coughs)
I-If you were looking at us from the outside...
...our world would've looked pretty small.
(coughing)
Um... Uh, it was, it was just the two of us
and whatever cat we were hiding from the landlord. (chuckles)
-(soft laughter) -I can,
I can promise you, though,
our world didn't feel small.
(coughing): And...
I'm sorry. I-I can't. (coughing)
FUNERAL DIRECTOR: Is there anyone who'd like to continue?
Maybe say a few words of their own?
HOLLIS: Thank you.
(mourners murmuring)
(coughing)
STEPHENS: I, uh, I only met
Mo Pitter a few weeks ago.
I was lucky enough to sit with her as a hospice volunteer.
(Hollis continues coughing)
I'm a better person for having known her.
-I'm so sorry for your loss. -Oh, thank you so much.
Thank you for being here. Thank you.
(coughing)
-Are you all right, Hollis? -Oh.
Just fighting something. Thank you for being here.
-A-And thank you for that. -(chuckles)
I did my best. I'm not you. I'm not a writer.
Well, I'm not a writer yet. I serve coffee.
I haven't seen you since the hospital.
I was with your mom at the end.
She gave me this. Said it's stuff that you should have.
-Documents and things. -Thanks. (coughing)
I'm concerned about that cough. You've had it
-for a couple of weeks now. -It's fine.
Nothing I can do about it anyway.
I don't have insurance, so...
It's not just the cough, Hollis. Your eyes are puffy.
Your ankles are swollen. Looks like
-you're developing edema. -STEPHENS: You should come into the clinic today.
We'll see you free of charge.
(coughs)
(sighs)
(classical violin piece playing)
HOLMES: Watson.
You got my note.
How'd you get into my office, Holmes?
Disguised myself as a hospital caretaker.
Even did a bit of dusting.
Sorry.
I left without saying goodbye.
Not worried about that, Sherlock. You're sick.
You need to see a neurologist.
(scoffs) I've seen one.
You were right, my friend.
About the Cobalt Fissure. About the tumor in my head.
About all of it.
I was sick.
You helped me see that.
-But I'm better now. -No, you had a tumor. That was just three months ago.
I've been to Dr. Nielsen's clinic, in Copenhagen.
A nip and a tuck,
and I'm on my way to a clean bill of health.
Honestly.
I feel like a new man. Healthy,
and ready for what comes next.
For the grand unveiling, you might say.
Indulge me in a spot of showmanship first.
Once the mural's uncovered, I'll announce myself.
In the meantime, my thoughts are flowing,
my faculties are sharp,
and I'm ready to solve mysteries again.
(phone chimes)
And, uh, one other thing, my friend,
I'm ready to open offices here.
-You're moving to Pittsburgh? -No, not full-time.
An office here, maybe another in London.
We can work together again.
I'll take whatever time you can spare.
I imagined you happier.
(sighs)
I mean, yeah, I am happy, but why didn't you call me, Holmes?
I could've helped.
I mean, you had a brain tumor just three months ago.
You can't just shake that off like it's a hangover.
(sighs)
(phone chimes)
(typing on phone)
-Do you think the hospital... -(phone whooshes)
...might lease this space to me?
It's obvious, right?
We did an extremity ultrasound,
medication history,
and screening labs for kidney disease.
It was mostly negative, except for... Uh...
Watson, you good?
Oh, I'm sorry. My head was someplace else.
Um, listen, you two are excellent doctors.
You can interpret a chem 7, same as I can.
But she's young.
She just buried her mother this afternoon.
We were hoping we missed something.
I am sorry. You brought her in?
I should've cleared it with you first,
but I knew her mother. It was a favor.
WATSON: It's okay.
Well, she's our patient now,
so we have to tell her.
Kidney failure. That's...
Stop. I'm-I'm only 25. Kidney failure?
SASHA: We're gonna put you on dialysis right away.
It'll tide you over while we wait.
(coughs) Wait for what?
You're gonna need a kidney transplant.
Now, I'm not gonna pretend like that's good news,
but once we match you with an organ, this can be managed.
It's a life-long process, but you'll be alive.
I looked up my symptoms online. I thought I had hay fever.
-WATSON: Yeah, it sneaks up on people. -(coughs)
But it's very good that Dr. Croft and Dr. Lubbock
saw you today. I'm so sorry, Hollis.
HOLLIS: A transplant. How long
will that take? Isn't there, like, a waiting list?
It's called the UNOS list, and we'll get you on it tonight.
It can take months. Sometimes, a year or more.
Will I... last that long?
That's what the dialysis is for.
The good thing about kidneys, though,
is everyone has two of them.
So, if you have some relatives
or something we can reach out to,
we can explore something called a directed donation.
It-it was just me and Mom.
Her parents are gone. I-I don't even know who my father is.
He was an anonymous donor.
Just some guy that visited the sperm bank a few decades back.
I'm alone.
STEPHENS: No.
You're scared.
Your mom died,
and you just got terrible news.
But you are not alone.
Not tonight, anyway.
If you want, um, I'll sit with you.
At least until you fall asleep.
Yeah.
The Left Hand of Darkness
-by Ursula K. Le Guin. Yeah? -Mm-hmm.
INGRID: Sasha, want to get in on naming Adam's triplets?
(sighs)
I like "Beulah."
-Of course you do. -ADAM: Uh, you've been working
on this all day, and so far,
the suggestions are "Beulah," "Sparrow," and "Undecided"?
Maybe hit it fresh in the morning, huh?
Or maybe we can just leave the man alone
and get back to work.
STEPHENS: Hollis was wrong.
She's asleep already?
Thought you'd be awhile.
Hollis was wrong about not having any family.
Very wrong.
I sat with her mother the day she died.
She gave me this envelope to give to her daughter.
Hollis asked me to look at it while she rested.
It had her birth certificate, some other stuff, and this.
Is this real?
Mo Pitter did one of those testing kits using Hollis's DNA.
Those are the results.
Hollis Pitter has 42 half-siblings?
42 who used that same testing kit. There could be more.
That's a seriously dedicated sperm donor.
42 relatives,
each with a statistically higher chance
of being a donor for Hollis.
If we can figure out who they are.
* *
SASHA: Her eyes are stunning.
INGRID: Hollis's mom didn't have heterochromia,
which means she got them from sperm donor CM217.
One man, 42 progeny who may have stunning eyes.
42 that we know about.
CM217. Are you sure that's the donor ID number?
Mo Pitter wrote it down twice and circled it each time.
Okay, well, whoever he is,
any of those kids
would be a potential donor match for Hollis Pitter.
The more we can learn about him, the better.
He donated anonymously.
We need a court order to get around that.
Or a doctor who's willing to work with us.
No donor is supposed to donate more than 25 times,
so something is definitely off here. Crofts,
you two are in charge of Hollis Pitter's
current care. What do you recommend?
She needs a CT scan to prep her for dialysis.
A kidney biopsy, as soon as we can get one scheduled.
Okay, good. Get on that
and give me a report on underlying conditions
that might've caused Hollis's kidney failure.
In the morning, Ingrid and I are gonna
head over to the fertility clinic
where Hollis was conceived.
See if we can get anywhere there.
And, Sasha, you're Miss Congeniality.
-Uh-oh. -That sounds patronizing.
Get Mo Pitter's credentials from that DNA testing site.
Those type of companies, they have a messaging function.
Reach out to Hollis's half-siblings,
-tell her story. -So I get to reach out to 42 strangers
and ask them if they're willing to give up a kidney
for a half-sister they've never met?
Pretty much.
Congeniality, the hardest job of all.
What are you doing?
That's 42 e-mail conversations.
We need to clear some space to keep track of all that.
I put time into that.
Lauren and I picked out names already.
Well, are they from my list?
Watson. I expected you earlier.
Got hung up at the hospital with a patient. You made dinner?
Well, I'm a guest. I have to earn my keep.
You also procured a rather large map of Pittsburgh.
I did. I'm waiting to hear back
from the world's preeminent art historian.
So, in the meantime,
I thought I might solve every open murder case in your city.
Difficult without official records, but
I have made some progress. Have a look.
How long have you been discharged from the hospital?
Just over three weeks.
Do you have a follow-up appointment?
Due back in Denmark at the end of the month.
Hmm.
You're not even tempted?
I have made some headway
in the case of the so-called Shadyside Strangler.
You're a little behind.
They arrested someone two weeks ago.
Indeed they did, but-- but I believe
a second criminal snuck another murder in there
and made it look like the work of the Strangler.
Chap called Owen Murdoch.
Lives on Butler Street. Have a look
under the pots where he keeps his zinnias, you'll find
the evidence you need.
Do you have contacts, local police?
Mm-hmm. I do. Lestrade. She's good, but...
You're skeptical. I understand.
Consider this a trial run.
If this tip is good, and you're still interested,
then perhaps this is the basis
for a new and better partnership.
I haven't found one worthy of a collaboration just yet,
but it's only a matter of time.
This is fun, Watson. It's good to be back.
(elevator bell dings)
LESTRADE: Watson.
What got into you last night?
Detective Lestrade.
Sorry, I'm cutting back on the caffeine.
More for me.
So what gives? You take a little blue pill,
only for solving murders?
Was the tip not satisfying for you?
Very much so. We made an arrest this morning.
-I thought you'd be happy. -Well,
next time you have yourself a murder-solving hoedown,
give me a holler.
I'd really like to meet the world's greatest detective
some time. You mentioned him before.
I figured this sudden
and mysterious burst of productivity...
Nah, it's just me. Sorry to disappoint you, but just me.
Mm-hmm.
Okay.
42 brothers and sisters.
I was up for hours last night
making up stories about who they are.
(coughs)
Did anyone answer Dr. Lubbock yet?
Two responses so far. Thank you.
They said no, didn't they? (coughs)
-That's what I'd do. -Hmm...
Don't write the ending before it happens.
People can surprise you sometimes.
(Hollis coughs)
Seems like this has been a really good thing for you.
Sitting with hospice patients.
-You seem more connected to people. -STEPHENS: I love it.
Maybe that's a weird thing to say
about watching people die, but I do.
They share their lives with you.
They remind you what matters.
So, you have names for the triplets.
Does that mean that you know what you're having?
-Two girls and a boy. -(laughs)
Two girls. What are you gonna do?
Learn on the fly.
I kind of lied about having all three names picked out.
The girls' names we have all sorted.
One name for Lauren, one for me.
But the boy's name?
It's a bit of a conflict zone.
-Lauren wants to use a family name. -Can I ask?
-Kelly. -Kelly?
Interesting. I like it.
-Mm-hmm. -No, I do.
You just don't hear of that many boys named Kelly.
I was wondering, actually.
You are Stephens Croft the Fifth.
Are you gonna designate a Stephens Six?
'Cause, man, I could really use it now.
My kid's gonna be named Kelly.
You're Adam Croft. You could go with Adam Croft, Junior.
Doesn't exactly bear the weight of generations, does it?
I don't want to step on your toes, but
if you don't plan to use it...
Do you plan to use it?
RECEPTIONIST: Donor CM217.
-Do I have that right? -WATSON: That's the number, yes.
Of course, we can't share information
about donors or patients.
Okay, I understand that, but we were hoping
to have a word with Dr. Day.
But I did call the sperm bank after I got your e-mail,
and I can tell you that Donor CM217 doesn't exist.
It's not even how the bank does the numbering.
Somebody donated the sperm
that made Hollis Pitter and 42 other people.
I agree it's strange.
Let me get Dr. Day. He asked me to get him if you all came by.
Do you remember, um, that friend of mine
who had the neurological symptoms a while back?
I asked you to examine him.
I remember the empty room where he was supposed to be.
Okay, well, I'm in touch with him again.
And you were right to be worried.
There's a brain tumor.
Now, he claims to have had a resection
at Dr. Nielsen's clinic in Denmark.
Claims?
I don't know. I mean, he's up and about,
and it's all kind of fast.
Seems a little strange.
Do you know someone at the clinic?
I mean, casually, from conferences.
Okay, can you reach out?
They're not gonna share patient details.
No, they don't have to. I just want to know
if they did any tumor resections during that window.
You think your friend's making the whole thing up?
OLIVER: John Watson?
Oh, it's not every day a legend comes calling.
Legend? Well, I don't know about all that.
Oh, please. We're just a fertility clinic,
but we still work in genetics. You're a celebrity.
Oliver Day.
I understand you're working with the daughter
of one of my patients?
Dr. Watson? Everything okay?
LESTRADE: You're having yourself a day.
Looks like you found yourself a superspreader.
Superspreader?
INGRID: Sorry, you said, "superspreader."
You just had that ready to go.
I've been married to three different women, Dr. Derian.
I'm well-acquainted with the perils
of artificial insemination.
You get your odd fertility doctor
decides that his own seed stock
is better than what's for sale down at the market,
and you get yourself a superspreader.
They used to get away with it,
up until all these ancestry websites popped up.
He's not bad-looking. For an old guy.
Stop. He's the ultimate creep.
Hollis's mother must've been suspicious,
given the heterochromia.
Why else would she have sent that kit in?
None of this is hard to prove.
Assuming you have a sample of the good doctor's DNA.
We'll need a court order for that,
and that will take some time, but why don't you come
to the fertility clinic with me?
We can share our suspicions of Dr. Day.
We can offer him a chance to come clean
and share a list of all those patients he defrauded.
Any one of those offspring
could be a good donor match for Hollis.
By the way, how is our patient?
Image showed an abdominal hernia.
We can't do peritoneal dialysis,
so we placed a hemodialysis catheter instead.
Hm. And the charm offensive?
Four responses so far. Two noes, uh...
-(tablet chimes) -...two requesting for more information.
INGRID: Hollis's results just came back.
Biopsy, genetic tests, all of it.
Watson, you should see this.
HOLLIS: Alport syndrome?
I've never even heard of that.
It's a rare genetic disorder.
We think it explains why you're in kidney failure
at such a young age.
(coughs)
And I've-I've had it my whole life?
Yes. You actually have the autosomal recessive version
of the disease.
That means you inherited it from your mother and your father.
(sighs)
(groans)
Do you want to hear something funny?
I got an e-mail from an editor last night.
I'm set to have my first story published.
-That's incredible. Congratulations. -Mm.
Weird Tales. It's a long way from The New Yorker.
-(phone buzzing) -(coughs) The editor has notes.
Hopefully, I can live long enough to turn them around.
I'm sorry, excuse me for a second.
-Hello? -HOLMES (over phone): Watson.
There's a dead florist in Oakmont.
The sister keeps a certain locker at the country club.
Look inside for the evidence you need.
-I'm working right now, Holmes. -You and I both.
It'll take you 30 seconds to pass this along.
More to come.
You saw that HD cath, same as I did. It's infected.
I just took Hollis's temperature.
101.4.
LESTRADE: A locker at Oakmont country club?
WATSON: Yeah, you should ask them to give you a peek.
I bet you'll be happy.
You're staring at me.
Indeed I am.
Dr. Day can see you now.
OLIVER: A geneticist, a detective, and a fertility doctor
sit down for a conversation.
Kind of sounds like a set-up for a joke.
Have you been living in dread, Dr. Day?
Uh, not that I'm aware of.
All these ancestry websites just popped up
out of nowhere. An entire network
of people carrying your DNA,
just writing back and forth to each other.
Nothing you can do about it.
OLIVER: "Carrying my DNA"? Uh...
I have three kids. They're the only people with my DNA.
We know you have more than three children.
Okay? You're Hollis Pitter's father.
And you have other children.
We're tracking 42 through a website.
You have a cluster here and a cluster in Michigan.
Did you practice medicine in Detroit,
-by chance? -WATSON: Hollis Pitter has Alport syndrome.
That means you're a carrier. All of your children--
I don't know, however many you created--
could develop that disease. They deserve to know about it.
I have no idea what you're talking about.
We're very busy here today, so if you wouldn't mind...
We're gonna take this all the way.
We're gonna compel you to give us a sample of your DNA.
WATSON: That could mean an army of civil suits against you.
Possible prosecution.
The end of your medical practice,
the complete destruction of your reputation.
Now, I'd imagine your family
might have a point of view about that.
Come forward now, get out ahead of it.
It'll look better for you.
Listen, Dr. Day,
maybe you thought you were helping these women.
Maybe... maybe there's some other reason, I don't know,
but you have a child out there who's sick.
Hollis Pitter. She's 25 years old,
and she's in kidney failure.
We're giving you an opportunity to do something about it.
I'd like you to leave. Now, please.
Okay. No, no, I totally understand.
Thank you so much for considering.
-(sighs) -Another no?
She's concerned about Alport syndrome.
If that woman's a carrier, then her kid might have it.
She doesn't want to donate a kidney
that her own kid might need.
So, Adam's having a boy.
Two girls and a boy. Um...
He wants to name him Stephens.
-What an honor. -(both chuckle)
You two have, uh, you two have come a long way.
Stephens Croft the Sixth.
Means that I can't use it.
It means, um...
I don't know. Um... Means that we can't use it.
Which might be fine. I-I don't know.
Do we want to use it?
I mean, should we even talk about this?
Stephens...
That is completely up to you.
I've brought up kids, like,
five different times that I can count.
Have you?
W-Well, not like, in a "let's have an official conversation,"
but I give you an opening, you just, um...
never walk through it.
You can give the name to Adam if you want.
Of course you can. It's your birthright.
Or...
we could talk about it.
WATSON: Anything new on the half-siblings?
Oh, uh, just two more noes.
That's too bad. Our timeline just shifted.
Hollis's HD cath was infected. I had to take it out.
That's the only way she can get dialysis.
I know, and without it,
she doesn't have years to wait for a new kidney.
She has days.
Hollis needs a functioning kidney now,
or pretty soon, she'll be dead.
(sighs)
HOLMES: Cherry Mazin.
Disappeared from the community of Apollo.
I think he has her, Watson.
So what are we supposed to be doing here, Holmes?
Solving crimes.
Isn't that what we always do?
Isn't that how we find our way back to true north?
True north.
Who's supposed to be lost? You, or me?
Well, that's a hard question.
We're best friends.
Sometimes, I guide you to the next step.
Sometimes, the reverse.
(knock on door)
Who can that be?
Discretion, Watson.
I'm not a public figure just yet.
WATSON: Detective Lestrade. Did I give you my address?
You did not.
We arrested the Oakmont Killer.
That's three murders solved in 24 hours.
-You're welcome. -Mm-hmm.
He's real, is he? The world's greatest detective?
Of course he's real.
Can I get, like, just a quick glimpse?
What makes you think he's here?
Clippings on the wall.
This sudden burst of helpfulness.
I don't know.
Am I wrong?
No sign of the guy, huh?
I don't know what you mean.
It's just you and me here.
Uh-huh.
Well, I have news.
Oliver Day called 911 an hour ago.
They found him hanging from a beam in his garage.
-He's dead? -Not quite.
Dr. Day called in his own suicide.
He waited till he heard the sirens in his driveway,
and then he hung himself.
He's on life support right now,
because he left a final gift.
Dr. Day left notarized instructions.
He wants to be kept alive long enough
to donate a kidney to his daughter.
To Hollis Pitter.
(monitor beeping)
(monitor flatlines)
WATSON: Oliver Day has been drinking the pain away.
Drinking the pain away. What does that mean?
It means he apparently feels guilt
over impregnating God knows how many women,
and he tried to alleviate that guilt
by leaving Hollis a kidney,
but the damage was already done.
He has undiagnosed cirrhosis, which seems to have
led to subsequent kidney damage.
Which means he can't be a donor.
How is Hollis?
Not great. She's getting sicker.
-And Oliver Day is gone? -Mm-hmm.
Ingrid and Adam, I need you two to reach out to UNOS,
see where Hollis falls on the list,
but make sure they know that she's getting worse.
Sasha and Stephens,
once Oliver's family organizes a funeral,
I need you two to
work a different angle.
* *
So, so sorry.
SASHA: A different angle?
That means what, exactly?
Am I supposed to just slip up to one of Oliver Day's kids
and say, "Sorry for your loss.
"So, you have a secret half-sister.
"No. No, wait, you have 42 secret half-siblings,
"but your sister? (sighs)
She could really use one of your kidneys."
Well, it's not easy to be Miss Congeniality.
-Okay. -(sighs)
Well, technically, I'm just here for moral support, but
I do believe that that's what Watson wanted, yes.
Yeah. Yeah, that's what I figured.
MAN: Yeah, but you're wasting your potential.
JASON: Oh, I'm wasting my potential? I'm doing just fine.
-Thank you. -MAN: Well, you have a lack
-of discipline is the problem. -I lack discipline?
Well, at least I don't lack compassion.
MAN: Okay.
Shh. Show some respect.
Are you seeing what I'm seeing?
Huh.
INGRID: Oliver Day has an identical twin?
He has an identical twin who's also a fertility doctor.
Harrison Day has a clinic in Grosse Pointe, Michigan.
There's a cluster of offspring in Detroit.
Hollis has 19 half-siblings in that area. That we know about.
If they're identical twins, they have identical DNA.
Ask us how we know about that.
That means, well...
Let's say that Harrison Day was also using his own sperm
to impregnate his patients without their knowledge.
Any of those kids, genetically?
They'd be Hollis's half-siblings.
If you follow that logic,
Stephens is about to have triplets.
-Take that back. -INGRID: Oliver and Harrison,
identical twins, both with the same pathology.
They both just happened to knock up their patients?
WATSON: Even if we're not sure
what Harrison did,
there still is a leverage point.
Detective Lestrade can reach out to Detroit PD.
Compel a sample of his DNA. Won't be hard to prove.
Not with time, but Hollis doesn't have time.
She's dying now.
Yes. We're aware of that, so we need to learn
as much as we can about Harrison Day
and any of his offspring.
Lestrade can lean on him from there.
And yes, you're right, we have to move as quickly as possible.
Watson. Do you have a sec?
Your friend, the one with the brain tumor?
You need to have a serious conversation.
We talk all the time.
Well, then maybe you need to end the friendship all together.
Look, the clinic you asked me to call,
they do pure research now.
They haven't performed a resection, or any operation,
in eight months.
This person, whoever he is,
maybe he had the operation someplace else,
maybe he just made the whole thing up.
But from the outside?
It looks like you're getting played.
Thank you for bringing this, my friend.
One can never practice too much.
You know, I wish I knew how to play an instrument.
Seems like it would be helpful when I get stuck.
You're stuck on something, my friend?
I got a patient and a crime and a case.
Twin brothers, fertility doctors,
with decades of deception between them.
Sounds like an interesting story.
Certainly worth an evening's thought. I'll put the kettle on.
It's Oliver and Harrison Day.
They both practice medicine in two different states.
Now, what I can't really figure out...
One brother is still alive,
and the other was buried today.
Now, I'm still trying to piece it all together in my head.
Now, how do they both commit the same crime?
Doesn't feel like coincidence.
Each would have to know what the other was up to.
I agree.
Let me ask.
In Oliver Day's office,
did you see anything relating to Genghis Khan?
Books, souvenirs, anything?
-How'd you know that? -Lucky guess, I suppose.
My strong guess is,
considering the-the baby cluster in Michigan,
is that you'd find exactly the same books
in Harrison Day's office.
Now, why might Genghis Khan
matter to two brothers
who spread their DNA far and wide?
Well, Genghis Khan is the world's most prolific spreader
of his own genome.
17% of the DNA on the planet can be traced back to him.
Which might be the only form of immortality
available to us mere humans.
Oliver Day had a fascination with Khan,
and he fathered who knows how many children.
His brother, based on available evidence,
seemed to be involved in exactly the same pursuit.
Now, what's the story there, Watson? Fill in the blanks.
They had a contest.
Two brothers who have the same genome,
each believing that their own DNA is superior,
so they chose a profession to spread it far and wide.
Which would explain the baby cluster here
and the one in Michigan.
They were trying to outdo each other.
-It was a contest. -Contest. (chuckles)
(laughing): Wow. What a world.
A contest. Oh, this is fun, Holmes.
-I miss this. -(both laughing)
(phone ringing)
Shinwell.
Get everyone on the phone. I have a new theory.
SHINWELL (over phone): Can't wait to hear it, guv.
But I think you should get down here
as soon as possible.
John Watson. I know about you.
Oh, I know about you, too, Dr. Day.
You and your kids all refused to help Hollis Pitter today.
It's a big ask.
A kidney for a total stranger.
Let me ask you a question.
Who won the contest?
I'm assuming you know the police
are sniffing around your business.
Which... I'm sure that's why you're here.
Mm...
Those ancestry websites. (chuckles)
They're a scourge. Don't you agree?
It is a lot of information to turn over to a corporation, yes.
Our very innermost secrets,
and we choose to just hand them over.
To who, exactly?
Those people do not have our well-being in mind.
Neither of us like those registries.
But beyond that, you and I have nothing in common.
Huh.
Dr. Watson, I'm happy to tell you everything you want to know.
I'm happy to describe
any and all malpractice
committed by my brother Oliver--
oh, and by me-- in our practices.
There's a fairly good chance that
I'm a donor match for your patient.
I'm even willing to donate a kidney to keep her alive.
And why would you do that?
Oh, a trade, of course.
I'll admit what I did
and donate a kidney to save your patient's life,
in exchange for full immunity for any crimes
that may have occurred.
Well, the choice is yours, Dr. Watson.
Ruin my life, put me in jail,
or save this young woman's life.
What's it gonna be?
SASHA: (sighs) If you can hear us, Hollis.
We have a promising lead on a donor.
I really hope you get your story published.
He's a match. We got the labs back.
Same blood type. HLA lines up better than we'd hoped,
crossmatch is clean.
You lost me back there after blood type.
Dr. Harrison Day is a viable donor.
Good thing. Prosecutors in Michigan
are willing to offer full immunity on fraud charges.
As long as Day signs a full confession
and forfeits his license to practice medicine.
WATSON: Yeah, I don't think that's gonna be a problem.
Harrison Day is proud of what he did.
Part of him wants the world to know that he won.
His genes reign supreme.
MARY: John, we good?
What is it?
I'm not there yet.
I'm not ready to hand Harrison Day a hall pass.
I have one more move left.
A Hail Mary.
MARY: Whatever it is, do it now.
Hollis might not have another day.
Thanks for meeting me.
You said my, uh, dad did something bad?
I'm not surprised at all.
What was it, specifically?
Your father, Harrison Day,
impregnated a number of women with his own sperm.
Your uncle, Oliver Day, did the same thing.
They had a contest.
(scoffs)
You don't seem surprised.
Man has an ego.
He gave me hints along the way.
So, here's your chance to do something about it.
I hear you two didn't get along.
Not even remotely.
Well, I have a patient, her name is Hollis Pitter.
She's very sick.
Your father offered to donate one of his kidneys to her.
Let me guess, as long as he gets away with everything?
And if I'm a match?
If you're a match, then you give up one
of your two kidneys. Now, I know that's no small ask,
but if you don't do it, we have to use your father's kidney.
Jason, if you don't volunteer,
your father is gonna get away with everything.
WATSON: It was a Hail Mary.
Doesn't mean we shouldn't have tried,
but it was a Hail Mary.
INGRID: Harrison's kid isn't a match?
No, he's currently being treated for basal cell carcinoma.
It's very mild, it's very manageable, but it's still
a contraindication for organ donation.
Wait, basal cell?
That's like the houseplant of cancers.
Half the dermatology building has one.
UNOS rules don't distinguish between "mildly inconvenient"
and "existential threat."
History of cancer equals no kidney donation.
ADAM: So that's it?
-That was our Hail Mary? -WATSON: Correct,
which leaves us with exactly one option.
-We cut a deal? -We cut a deal.
Harrison Day is a donor match.
He can save our patient's life.
It's a win.
We won.
* *
(sighs) Watson.
How's my niece?
Hollis is in recovery.
We just need to keep our eye on you for
another day or two, then
-you should be able to fly back home. -Mm.
Glad I could help.
(groans) I took this from my brother's office.
A souvenir to remember Oliver.
You seem satisfied.
If I lost my practice,
my reputation,
my standing in the community,
I don't think I'd have that look on my face.
Oh, I keep my eye on the prize, Dr. Watson.
Money, standing,
all that other stuff, that's just ephemeral.
(sighs) We're here to survive, every one of us,
and the way we do that is by passing ourselves along.
That's immortality.
That's the only victory available to any of us.
You asked me before
who won the contest between me and my brother.
You met us both.
Oliver believed the same things I did.
(laughs) But he was soft.
I won. Of course.
(chuckles) Who else?
-(knock) -SASHA: Hey.
-Hey. -How's she doing?
Stable.
I think she's gonna wake up soon.
So...
I'm gonna keep the name.
My name. Stephens Six.
Maybe I use it.
Maybe we use it.
Yeah, maybe.
-Oh. -Hey, uh,
listen, I made an appointment.
It's something I've been thinking about. Um...
I'm gonna freeze my eggs.
Sorry, should we have been talking about this?
I've been trying.
I'm-I'm not upset.
You are where you are, but
time is time, and this...
this can't wait forever.
Can I go with you?
I'm not sure.
I love you, Stephens,
but whether you're there or not, this...
...this doesn't feel like something we're doing together.
HOLLIS: Hi.
STEPHENS: Hollis.
Your surgery was a success.
You're doing great.
I've been waking up and falling asleep.
I think I know how to fix my story.
-Uh, c-can you help? I'm worried I'll forget. -STEPHENS: Sure.
"The colony was called Azurinari.
"It was a backwater, little thought of
by the ruling class of Myinari."
Mm...
"But that solstice, everything would change."
Sounds like your patient has every prospect
for a long and healthy life.
Oliver Day found justice at his own hand.
Even Harrison had a reckoning of sorts.
Harrison Day looked smug as hell for somebody facing the music.
Every puzzle only promises an answer, Watson.
Justice isn't always on the docket.
Still and all...
between the strange case
of the Day twins
and our small dent in your city's backlog...
...I'd say we're on a good run.
That look you're giving me. It's, uh...
fraught.
I need you to do something for me, Holmes.
I need to introduce you to somebody.
Doesn't have to be someone we know. It could be Lestrade.
She doesn't care if you're still alive
and she's not gonna say a word to anybody.
I just... I need to have a conversation
when it's not just you and me.
And why is that, exactly?
Because things have been strange.
I know you didn't have that operation.
At least not in Denmark, you didn't.
You're my best friend, Holmes.
I worry about you, but now, I'm starting to wonder if...
I'm starting to wonder if I'm the problem.
I don't follow you, my friend.
I need you to come with me, Holmes.
I need you to do this.
Yes, I suppose it's time.
You did all this together?
You and this guy. Sherlock Holmes?
We did.
That makes me a little insecure as a detective.
He's been working with me.
All those tips the past few weeks,
the solution to the Murder Nurse case,
it was all with his help.
"The world's greatest detective."
I want you to meet him.
He's gonna be working here
in Pittsburgh. You two should know each other.
Give me a minute.
Holmes?
I'm ready for this.
I think we both are.
Detective Lestrade, meet Sherlock Holmes.
Aren't you gonna say something?
Say something to who?
HOLMES: Always another turn, Watson.
Always one more surprise.
What is this, Watson?
There's no one there.
