-=Episode 9=-
The two of you, where have you been and what have you been doing, only to show up now?
Is BA3 in Busan or something?
In terms of work ethics, this is a violation of national law...
A suicide occurred at the hospital.
Suicide?
Dr. Lee.
What is this?
These are interviews with the isolation ward patients concerning the unusual activities that has been going on there recently.
Why are you doing all this?
Although I know you are one who wear many hats--
I need the experts opinions.
So you want me to take this inside and show it to them?
Yes, now please.
This should be reported by the isolation ward, why should I be the one to do it?
And also, they announced to the whole nation
that M-virus has been contained at a press conference not too long ago.
This is like pouring cold water over everyone, what's your intention in asking me to handle this?
- Then I'll handle it myself. - What?
Hello, I'm Gang Ju Heon.
I have something to report. Right now.
Where are you?
Yes, I understand.
Everyone is currently in the operations room.
=She said cutting her wrists didn't work.=
=She gave me a piece of cloth and asked me to tie it for her. That was all.=
=Gim Hye Mi climbed on top of the table and got down. Then you climbed on the table again,=
=what were you trying to do?=
=The noose was slightly small. Her head couldn't fit in.=
=So I loosened the noose a little.=
- =Then it fit nicely.= - Pause it for a moment.
You are not saying that this is evidence of neurological disorder, are you?
Because Mr. Gang kept persisting...
Is Gang Ju Heon an expert in viruses?
Let's take someone who has suffered shock, a madman with neurological abnormalities for example--
Team Leader Gim.
Mr. Gang is not an injudicious person.
Let's continue watching.
- What is there to watch? - Let's watch until the end.
If we have time to watch this--
=Do you still remember what happened yesterday afternoon?=
=I felt weak. It was the first time I experienced it.=
=Can you describe in detail what happened to you at that time?=
=The sensation is like having eaten something hot. My heart was burning.=
=So what did you do?=
=I wanted to vomit, but no matter how I tried, I couldn't throw up.=
=I felt if I could only throw up then I will feel better.=
=My head hurt like it was going to explode.=
=Didn't the doctor attend to you?=
- No matter how you look at it - =You remember?=
this can only be explained by neurological disruption.
The neurological changes are caused by M-virus mutating.
Are you saying the virus has started to mutate?
Yes.
What mutation are you talking about?
There is no sign of fever, what nonsense is this?
I ran a chromosome comparison of the virus and the therapeutic agent in patients that were not responding to the treatment.
A few of the codons differed.
Are you certain?
Yes.
Then why are you only mentioning it now?
I wanted to be absolutely sure.
Team Leader Gang has given us the necessary data.
If only a few codons differ,
using the therapeutic agent that was developed prior to this, we should be able to counter it, right?
I had tried it, but it didn't elicit a response.
What's the possibility of developing another therapeutic agent?
The children miss you.
Don't tell them I'm ill.
I didn't. I said you're at a seminar.
You did well.
Dr. Choe and Dr. Jang have already been discharged from the hospital.
You'll get better too.
Yes.
You have to be strong.
Guardian, time's up.
Don't be so stringent. Give me another 5 minutes.
I'm sorry. These are the rules.
I'm going.
Oh, Su Jin.
=Oppa, are you okay?=
Of course I'm fine.
=Oppa, you're still in isolation, right?=
Yes, why?
=It's nothing.=
=How's your health?=
Very good.
Hearing your voice, I really miss you.
I don't even know when I can come close to you.
When will you come?
Oppa, didn't you say not to visit you before you've completely recovered?
=Forget what I said earlier. Come and pay me a visit=
Okay, I got it.
What do you mean a mutation has occurred in Eo Gi Yeong?
Didn't his body contain the antibodies? How can this be?
Taking advantage of the interval when host Eo Gi Yeong was weak,
the mutated virus took control.
How can this happen?
Therapeutic agent? Is there anything that can be done?
Presently, there's nothing we can do.
If we have to find the mutated section,
doesn't that mean we won't know how long it'll take?
Don't be too pessimistic.
We still have the research data from before.
What shall we do?
The New Year.
We must restrict all expressways across the country to stop nationwide travel.
What reason do we have to stop people from travelling?
If we start talking about mutations, this will only add to the citizens' confusion.
It won't help in any way to resolve our situation.
I agree with what Director is saying.
To put them in fear when we don't have a plan
isn't that an outdated countermeasure?
Yes, I have some issues with that.
So let's not officially mention anything about the mutations.
We can't do that.
How the neurological disruption will manifest itself cannot be predicted.
Only when the sufferers and their caregivers face up to reality
can they prevent mishaps that might occur because of neurological disruption.
If we were to make that kind of announcement,
it's equivalent to setting off a nuclear bomb in the Korean Peninsula.
If it's going to be a nuclear bomb, I think it's an even greater reason for us not to ignore it!
You are someone who should fully understand that in our position, we cannot make a mistake!
It's fortunate that the patients suspected of carrying the mutation are only found in our isolation ward.
Is that right, Professor Yun?
Yes.
So it's possible that it will just end here, right?
Yes. However--
If we make everything public,
have you thought what kind of chaos this country will sink into?
But if we let this be, it will plunge us into greater chaos!
You seem to have misunderstood what I said.
I don't intend to sit idly by.
Please develop the therapeutic agent as quickly as possible.
But however, before such patients are discovered in places other than the isolation ward,
refrain from making this public.
But the New Year is fast approaching,
- continuing on like this-- - The M-virus is already under control!
Didn't you say as much yourself at the national press conference?
Director.
There's a chance the situation may end with just a few casualties in the isolation ward.
We can't ruin the national holiday over this.
That is my decision.
Oh, I'm sorry. The meeting ran a bit long.
- How was it? Did it go smoothly? - Yes.
After we received your phone call, we've been discussing this matter too.
Taking complete control of the roads leading back home, no matter how I think about it, it's somewhat...
The chaos this generate will be on a scale equivalent to that of a uprising of a great revolution.
We can't let that happen.
The Ministry of Public Administration and Security has also been discussing this matter.
We came to the conclusion that the roads leading back home cannot be closed off.
The New Year can be said to be the most important time for fostering national spirit.
We can't turn it into a political burden.
Let's hope the holidays pass auspiciously.
In my opinion,
it would be helpful to have partial controls in areas where there have been outbreaks.
Appealing to the people to remain vigilant would also have an effect.
In case something were to happen, if they ask us what we had done,
at least we can answer that.
Partial control.
To proceed along those lines is a good option.
This virus thing,
is like a fire that has been extinguished re-igniting again.
We musn't let our guard down.
If partial control of certain areas is enforced
and if we put the entire country's health institutions on high alert,
I think we will be able to get through this.
Anyway, let's pull through this New Year safely.
We have successfully replicated the world's first synbodies.
How could we not get through this?
Anyway, we'll just put our trust in the director.
=On the first day of the New Year's holiday,=
=traffic congestion has started on all major roads.=
=However, it's not as bad as expected.=
=Using a smartphone application,=
=you can avoid the most congested roads.=
=We will keep you informed at all times regarding the road conditions.=
=Please stay tuned.=
These patients are infected with the mutated M-virus variant strain.
Isolate them from today.
Why is Eo Gi Yeong on this list?
He was also infected.
How could that be?
We don't know precisely either.
The listed individuals may exhibit symptoms of mental disorientation.
Please ensure you pay extra attention.
Have there been any new infections?
None up till now.
What did I tell you? We will pull through this.
What is there to be anxious about? There hasn't been a single case.
Administrator Pak, you should go home now.
Go home to see your children
and resolve the misunderstandings between you and your husband.
Actually, when Professor Yun Gyu Jin postulated the existence of the mutated variant strain,
my heart sank, and I even wondered if I would have to pay a visit personally.
I thought about it a lot.
But if by chance
the citizenry were holed up and not a single infection arose, as is the case presently,
oh my, just thinking about it is terrifying.
Now you can put your mind at ease and go and resolve your marital problems.
I heard you were looking for me.
Are you unwell?
Doctor.
Yes.
Please tell me the truth.
May I sit down?
Will...
I die?
Why are you asking me that all of a sudden?
Something is growing inside me, right?
Please tell me honestly why is this happening?
Viruses undergo mutation while they are in our bodies.
It's like their instinct for survival surfaces.
So if antibodies are produced to stop the infection,
even if it has to evolve, it will do so in order to survive.
It appears that M-virus has mutated.
We're presently examining you to check if you are in that situation as well.
H-How could that happen?
Didn't you say it wouldn't happen to me?
You said that, Doctor.
My body miraculously triumphed over the virus.
But... why do I...
Didn't you say I would be fine and that I'm just a carrier that would only infect others.
But...
Why am I getting infected?
Mutation is a separate matter to be reckoned with.
It's similar to the flu.
You do not get lifelong immunity to it after contracting it once.
Just like how you can contract different influenza strains, you will continue to be infected over and over again.
But this is not a cold.
This is an illness that can be fatal.
Discounting how unlucky a person I am
but twice,
isn't that too much?
It's probably because your body became too weak.
The bone marrow aspiration,
could that be the cause?
No, it's not because of that.
Your body became extremely weak because of your lengthy stint aboard the Munyangho.
Plus you were under a lot of stress while on the run.
Most afflictive of all, it's the injury you sustained when you fell off the bridge.
Although I don't know if there could be any other possibilities,
but it's not due to the bone marrow aspiration.
Okay.
Whether it's so quiet because of the incubation period,
or because of the implementation of the quarantine measures,
this deathly quiet feels even more unsettling.
I probably should have stayed at the office, eh?
Everyone is burning the midnight oil
except me.
It's still too strenuous on you.
Getting a good rest is the best thing you can do for the team right now.
You're quite familiar with the route.
I've done simulated driving on this route 5 times.
I can clearly tell what kind of student your were.
What kind of student do you reckon I was?
During examinations, even if the teacher were to give you every hint,
you'd be this doleful person who writes down strange answers.
Seriously...
Even if it's a cul de sac, you'll still gradually wind down that path.
Despite all the hints, you still won't get it.
You're not a novice
why did it take you 30 minutes to arrive here?
Just get out of the car quickly.
Once inside, don't even wash your face, just jump into bed and sleep.
Team Leader.
If...
someone who had not slept a wink in 3 days
says she wants to sleep for 30 minutes
or alternatively, she could spend that 30 minutes with the person she likes,
what would your answer be?
If you don't answer I won't get off.
Why are you asking the obvious?
What's so obvious?
Of course being together.
Wrong!
It's sleeping with the person she likes for 30 minutes.
Can't we take a nap here together just for 30 minutes?
Jeez, Dr. Lee, jeez.
How can I sleep in front of you?
That's so absurd, seriously.
Yes, ajussi?
Pardon?
Ah, all right. I'll come down right away.
Hello.
Happy New Year.
Yes, Happy New Year to you too.
Mom, why'd you come out?
Team Leader, you go ahead.
I have something to do. You go in first.
Mom, what is it now?
You don't have to be so anxious.
I won't make a big fuss today.
Dr. Lee, you'd better go in first.
If later on, should she happen to mention she has to go to work, please stop her.
She can afford to get a good night's rest.
Then
you are going back to the office for the night shift?
I wanted to invite you in to have some rice cake soup.
I'm somewhat...
So, take this.
I prepared some rice cake soup and pancakes.
You can share it with your colleagues. Enjoy it.
Thank you.
Now the whole neighbourhood knows!
Sleeping in the parking lot.
Come along.
I will enjoy the food, Eomeoni.
Did you call?
Yes.
I feel the drip is running a bit fast.
Okay, one moment.
Okay.
Do you feel any pain elsewhere?
Please raise the bed a bit.
Okay.
Is this okay?
Yes.
Excuse me.
Yes?
Can you help me to make a call to Team Leader Gang Ju Heon?
I have something I must say to him.
Fine, I'll contact him for you.
What else can I do? As I said, we're on high alert.
I can't.
No matter what I'm the team leader.
If people were to find out that I ducked home to eat rice cake soup while on high alert duty, I'm a dead duck.
I already said I can't.
Are you feeling better?
I already told you to take it easy with stuff like dishwashing.
No one will blame a pregnant woman for not doing any work.
Put Mom on the line.
Why else?
If she wants to see a beautiful grandchild...
I need to hang up now. I'll call you back later.
It looks like only I've slept.
It's better to take a nap while things are quiet.
Here.
What's this?
New Year's food.
In the kind situation we're facing right now, you actually took a trip home?
Oh, this looks delicious.
Shall we eat over there?
Hello, Epidemiological Investigation Team 1, Pak Do Gyeong speaking.
The isolation ward?
You're looking for the team leader of the investigation team?
Ah, hold on.
Mr. Gang.
Your call.
Hello, Gang Ju Heon speaking.
I heard you were looking for me.
Yes.
What is it?
You said this to me before, right?
If I said I "wanted to save people" or shit to that effect, you'd punch me.
What do you mean by that?
Why do you want to talk about that now?
I don't know.
Not able to see anyone,
all I can do is just stare at the ceiling all day long, alone.
I've been thinking a lot.
Seems like you have some misunderstandings about me.
There's no misunderstanding.
Then again,
There's nothing to know.
Have you heard what happened to me?
That I have been infected by the mutated strain.
Yes.
Although it was for a very brief period, I thought of you as my saviour.
Instead of saying you saved me, you did it to save everyone else.
But in any case, I survived.
But now they said mutation.
It would be better if I had died then.
At that time, I didn't think I could survive, or that I could do anything more.
I felt there was nothing scary about death.
I'm sorry to interrupt,
but what is it that you really want to say to me?
Have you heard the reason why I turned out like this?
It was because my body was weak,
that caused my condition to deteriorate.
If you reckon it's due to the bone marrow aspiration--
You'll take legal responsibility.
But you've already been forgiven by the law, haven't you?
Water please.
Is this newly installed?
Yes, Director.
The personnel for the isolation ward?
We have police officers doing their rounds at regular intervals.
Every room is guarded by elite officers.
During this time, deal with them on a one-on-one basis. They've all been separated, right?
Yes.
They've already been informed during treatment, they are to handle them one-by-one.
The patients placement?
Those who are recovering are all isolated on the 7th floor.
Currently on the 8th floor, we have housed those patients suspected of having symptoms of neurological disruption.
Dr. Lee, why are you here?
On such a cold day...
Where's our team leader?
Mr. Gang?
He should be at the isolation ward.
Why the isolation ward?
After a scuffle with an infected patient,
isn't it normal procedure to isolate him?
Nothing happen, right?
Team Leader is fine, right?
Yes, he's fine.
This is truly a touching and moving camaraderie, I'm moved to tears.
Don't do your worrying here. If you want to go, go.
And don't you think you shouldn't be dressed like that?
You saw it, didn't you?
They've already made their relationship public.
What do you mean relationship?
She's acting like that because she's worried.
Do you think she'll come dressed like that if that person is either one of us?
One uses duty and responsibility as an excuse.
The other uses camaraderie.
Both must really like acting cool.
Now even love is conducted using the science of metaphysics.
Dr. Lee.
Are you all right?
Did you see whom I was sparring with?
You should have been more careful!
On my way here, my heart nearly stopped.
Dr. Lee, it's you who should be more careful.
You haven't fully recovered yet.
If you catch a cold,
don't you know how serious things could be?
A person's first priority is to cherish themself.
Don't act without considering the consequences just because you're worried about someone else.
That's not what I want from you.
In future, remember to wear socks.
You heard what happened, haven't you?
Do you find me scary?
Why did you do that?
I was especially angry at that time.
Why only me?
What did I do wrong?
I am the only person who's infected twice.
I felt so wronged.
If I didn't vent it out on someone...
I understand, but still...
You're not that kind of person, oppa.
I have this strange feeling.
What?
I feel like there's something inside that's trying to push out.
If I throw it up,
it feels like the virus would disappear too
and I'll return to my normal self. That kind of feeling.
Are you worried?
Yes.
Afraid?
You are thinking how nice it would if be you didn't know me, aren't you?
Where do you get that?
We should have broken up when I boarded the Munyangho.
You are regretting it now, aren't you?
Oppa.
I'm joking.
Seeing how down you look.
Please make way!
About that, we're also not...
I'm sorry.
After we have the situation under control, we'll issue a statement.
It's not even a tsunami.
How did it become so widespread suddenly?
We didn't know it was in the incubation period.
We didn't take note of this because the therapeutic agent was successful.
It was our slip up.
When it was in the incubation period, all across the country, in every nook and corner,
friends and family were gathered under one rooftop to eat, drink and be merry.
On my way here I saw
all the ambulances in Korea are gathered here.
Don't you think the isolation facilities here are simply insufficient to house more patients?
I plan to contact Incheon's General Hospital.
After you contacted Incheon General Hospital, transfer all the patients from here to there.
And mobilize the medical brigade immediately and get ready the facilities.
Yes.
If during the New Year,
we had listened to Administrator Pak or Professor Yun... and taken full measures to control the situation earlier...
I know you'll feel we're to blame.
If we had done that,
perhaps the number of patients might be lower,
but looking at the current rate of transmission,
it's not a situation that could have been contained by just taking control of the roads at that time.
Yes, that's right.
If we had given full disclosure or whatever, that would only lead to greater confusion.
I'm of the opinion that by issuing the directive for partial controls during the New Year,
the director has done the right thing.
A judgement that took a second to make, so many lives...
Now is not the time to waste time by starting the blame game for something that has already happened, don't you agree?
Professor Yun, has there been any success over the New Year?
As of now, we can only search as to which codon has mutated.
Are you saying we should just sit and wait for a method that might take one year or 10 years to produce results?
Right now, I can't think of another method...
How can you utter such irresponsible words?
Everyone is counting on you.
You should give us some information that give us hope.
What do you mean by saying there's no solution in sight?
As in the case of the synbodies,
even without going through clinical trials,
the two of you were so full of self-confidence then.
What has gone wrong now?
At present, what we can do is to search where in the gene coding mutation has occurred.
Professor Yun is right.
Prof. Choe.
Prof. Yun clearly understands where the core of the matter lies,
but if you can't provide a solution,
even if you understand the core of the matter, they're just empty words.
Why did the situation become like this all of a sudden?
There's a sudden drastic increase in patients.
It's become an epidemic.
This is the natural course of viral infection.
You've heard of the influenza pandemics, right?
Right now it's exactly the same as it was back then.
When the Spanish flu first started,
similarly, there was a high mortality rate in the area where it occurred.
Then all of a sudden it started spreading,
and became one of man's greatest catastrophes.
Over 4 years, the number of people who died from the First World War was 8 million.
Do you know how many people died from the Spanish flu in just over 6 months?
25 million. Threefold.
Well, some said it was 100 million.
At our camp, we call this virus "Escape."
We call it that because it's like an escaping devil.
But when in Rome, do as the Romans do.
Here, we'll call it the M-virus.
Let's call the first virus that caused respiratory problems and haemorrhaging M1.
And the mutation strain that disrupts the nervous system M2.
Set up here, in the middle
is an electrical shock apparatus.
Normally mice will avoid the shock apparatus.
Mice infected by M2 virus--
Did you create mice that carry the virus?
I heard you ran up against the wall in that regard.
With time, anyone can do it.
I hope no one doubts Professor Yun's capabilities, okay?
There's no necessity for such misunderstanding.
Mice infected using human gene cloning
were placed within the apparatus.
Compared to the normal healthy mouse just now,
they appear completely different.
This is one characteristic of M2.
They die from self-inflicted electrical shock.
The screen will now show you an even more bewildering trial result.
M2's ruthless violent behaviour.
It doesn't merely end at self-harm.
Towards uninfected healthy mice,
they will exhibit rage.
I mentioned it earlier.
M2's greatest characteristic is its escape instinct.
Where does it escape?
It goes looking for uninfected, healthy, hosts.
They may even attack others.
They squeak loudly to lure the normal mice and then infect them through close contact,
either that, or they infect them through coughs or sneezing.
With the mindset of moving to a healthy host,
they have to mutate in order to spread easily among humans.
You have presented conclusive test results.
Although it's novel,
the M2 characteristic that you just mentioned
has been asserted by Professor Yun all along.
The problem lies with the therapeutic agent.
Have you been conducting trials to find the antibody?
Yes.
Can you tell us what specific method you used?
Within the glaciers in the Arctic,
there will be frozen virus specimens that are near pristine condition that has not undergone any form of mutation.
Using the above assumption as our starting point,
based on this original prototype,
after detecting the mutation segment, that is to say,
pinpointing correctly the part of the virus that's virulent,
with that information, we will be able to produce the requisite antibody.
Are you close to creating this antibody?
We are very close to creating the vaccine.
Close...
If it's close...
I've already successfully treated the mouse that was infected with M2.
Since the meeting has ended, how about we go for a drink?
Is that all right?
Didn't he say there's a treatment for M2?
I should be feeling happy,
but right now, I can't even muster an ounce of gladness within me.
Is it because the distrust I harboured against my husband
has now been transferred to Prof. Choe?
Anyway, this will leave a significant mark in scientific history.
I know.
Even though I know...
When Professor Choe was explaining the vaccine earlier,
I had a bit of a shock.
It's too similar to the paper you've been preparing.
Yes. Actually, I'm also somewhat...
I know under current circumstances to say it was plagiarized or whatnot would just add to the chaos.
But when he was explaining it earlier,
This feeling he had plagiarize your work came to the fore.
Did you perhaps show your paper to Professor Choe before this?
No, by right it's not possible for him to have seen it.
It's not even completed yet.
Theory is normally just a written idea but an experiment that uses a counterexample to prove the falsity of a theory requires a lot more specifics.
Besides my husband and I, you haven't shown it to anyone else, right?
No, I haven't.
You look very exhausted.
Have you been in the lab all this time?
Yes. Now I can even sleep in the lab.
Over the last 10 years, I've acquired some skills.
People always manage to adapt to their surroundings.
You're truly amazing.
We can chat about that later.
If we're to manufacture a vaccine,
you'd need manpower and equipment.
Just ask and I'll have it prepared for you.
Compared to our base camp, the equipment here is really state of the art.
But it's really difficult to conduct clinical trials here.
What is so difficult?
We need you to provide assistance to our base camp in the Arctic.
You can't conduct your trials at our facilities, is that right?
We have 200 cloned lab mice and 30 antibodies, all under cultivation
at our camp.
That will take 2 months to cultivate all that here.
There's a chance we might be able to discover the antibody for the virus by working here
but however, there are many limitations working in a lab.
I have another request.
Have some tea.
It's all right.
As for our lab facilities, I know they're already world-class
but I'm still unclear as to why it's necessary to provide assistance to that camp.
Since the virus originates from there,
Professor Choe is of the opinion he will find it an impediment to conduct the trials over here.
Did you come looking for me at this late hour because you too think his request is justified?
Yes.
But still, don't you think this request for assistance has crossed the line?
If we're talking about a 700 tonne research aircraft carrier,
we have to consider the depth of the seawater.
40 personnel to be provided now and 120 at a later date.
- a total of 160 specialists. - Sir...
Besides these, he has one more request.
He refuse to give up the patent rights to the vaccine.
How could a vaccine that's yet to come into existence have patent rights attached to it?
Seems like he intends to keep the patent rights to the vaccine he is going to develop.
He has obtained the patent rights for it in the US and Japan.
And
there seems to be some other related legal issues.
He's asking that they be settled at the same time.
Sir, I know these terms are very difficult for you to accept.
Sir, at this critical juncture
all we can do is to comply with Professor Choe's requests,
and get the drug manufactured as quickly as possible.
Where exactly is their base camp?
From the Dasan Station located in the Arctic, one still has to travel some distance to Cape Fligely.
If we decided to provide assistance then the first batch of personnel,
we must first contact Dasan Station so that they can prepare in advance for their arrival.
We'll go according to what you think best.
Yes.
Thank you.
There's still no reply.
This is the Dasan Arctic Station.
Professor Choe's base camp is here.
Our present coordinate is 11 degrees off the North Pole.
That means we'll be there soon.
This is really arduous.
Before the first batch of personnel depart from South Korea, we must make all the necessary arrangements.
We still have to get the lab ready. We are running out of time.
What is it?
I see it.
Where?
I apologize for putting you to such trouble when you are already so busy.
You don't have to apologize.
This arduous trek will be very taxing on you.
I've been to the South Pole before. I should be all right.
Is everyone here?
Professor Choe has yet...
Who's there?
Professor Choe.
Professor Yun, I think I've brought the virus here.
What do I do?
-=Next Episode Preview=-
It's too dangerous! Quickly seal the lab!
If there are survivors at Professor Choe's research camp...
I heard Professor Gim is your daughter's doctor.
There's someone in the lab, right?
Nobody can leave this place.
Everyone must remain in their places.
