following us?
-What are you doing?
-Let's just see what he wants.
No, let's just get out
of my neighborhood first. Come on.
-Did you see him today?
-No.
I did. I saw him this afternoon...
around 6:00.
Are you sure you didn't see him
when we drove past?
No, what?
I'm positive this afternoon
he was clean-shaven. I know he was.
He was ready to go to some function
with his wife.
He looks like he's got
a two or three-day growth now.
-Are you sure?
-No, I'm not sure, but I think so.
Rachel. This is Abe. Did I wake you up?
Can I get your dad's number
from you real quick?
Yeah. Okay, go ahead.
-Yeah, thanks.
-What's he doing?
He's just sitting there.
He got out for a second
and I thought he was coming over...
and then he got back in the car.
I think he's drunk.
Hi, sorry to call so late.
May I speak to Thomas Granger, please?
Yeah, this is James Miller
from Putney and Myers.
Hi, Mr. Granger?
Thomas Granger?
What are you doing here? Come here!
What happened?
I'm okay. I slipped.
I want to know what box he used.
You built one for you, right? Just one.
Yeah. How many do you think I made?
These are set right. I turned them on at 5:00.
He could have used one
and gone back to 5:00.
He could be in one of them right now.
I say we shut them off
and see if he's in there.
Were you planning on talking to him?
Just tell me if you were.
I'm not going to be mad.
No, I promise you. You know I wouldn't.
Are you sure you wouldn't?
You're the one he can't get near
without passing out.
There is no way
I would tell anyone about this. No way.
-Can you think of any reason you might?
-No.
Sometimes we do things
but don't know how we got to that point.
-No, I can't.
-Can't what?
I can't think of any reason why I would.
Well, I can't either.
What if it was an emergency?
-So you'd do it if it was an emergency?
-No, I don't know. What, so you might then?
I don't know. What kind of emergency?
The permutations were endless.
They tried again going to the source...
but even while keeping him separated
from Abe by two rooms...
Ask him his name.
...Granger's condition
could only be described as vegetative.
What did he say?
From this they deduced
that the problem was recursive...
but beyond that, found themselves
admitting, against their own nature...
and once again,
that the answer was unknowable.
-What do you think he changed?
-Not much.
We didn't have any contact with him
in the 3 hours he could've done anything.
I know he changed this. I know we weren't
having this conversation the first time...
so you don't know what we lost.
It really could not have been much.
It doesn't matter how much.
It just matters that it's changed.
I know what you're saying.
The question should have been...
what to do with the comatose man
in the guest bedroom.
But in Abe's mind
he was already compiling the list.
Two mg of oral triazolam...
every seven hours induces a safe sleep state
and a minimal metabolic rate.
At this continued state of rest...
the human body breathes
0.3 liters of oxygen a minute...
or roughly 2,000 liters in four days.
A Class E oxygen tank holds 625 liters.
To maintain hydration...
the body cycles through a minimum
of two-and-a-half liters of water per day.
Any food would be a luxury...
but the small tank
of medical grade nitrous oxide...
would be needed on the other side.
Past the room that contained their machines
and up two levels...
he made his way to another room...
where he had stored what I will refer to
from here on as the Failsafe Machine.
There he is.
I've been calling you all morning.
Really?
Your cell and work.
I'm not there.
Really?
I don't even know what.
I'm just tired.
I hope you're not implying
that any day is unimportant at Cortex Semi.
I was going to come give you
this big speech about how we've been...
friends for a long time and built up trust,
that whole thing.
But how about this instead?
If you ditch work this
