I'd be careful going that way.

We just had the floors waxed.

Yeah, I'm looking
for Doctor Strange.

You're about
five years too early.

Stephen Strange is currently
performing surgery

about 20 blocks that way.

What do you want from him?

That, actually.

Ah!

I'm afraid not.

Sorry, but I wasn't asking.

You don't want to do this.

You're right, I don't.

But I need that stone
and I don't have time to debate it.

Let's start over, shall we?

Please, please.

I'm sorry,
I can't help you, Bruce.

If I give up the Time Stone

to help your reality,
I'm dooming my own.

With all due respect,
all right...

I'm not sure the science
really supports that.

The Infinity Stones create

what you experience
as the flow of time.

Remove one of the stones...

and that flow splits.

Now, this may benefit
your reality...

but my new one, not so much.

In this new branch reality...

without our chief weapon

against the forces
of darkness...

our world would be overrun.

Millions will suffer.

So, tell me, Doctor.

Can your science
prevent all that?

No...

but we can erase it.

Because once we're done
with the stones...

we can return each one
to its own timeline...

at the moment it was taken.

So, chronologically...

in that reality...

it never left.

Yes, but you're leaving out
the most important part.

In order to return the stones,
you have to survive.

We will. I will. I promise.

I can't risk this reality
on a promise.

It's the duty
of the Sorcerer Supreme

to protect the Time Stone.

Then why the hell did
Strange give it away?

What did you say?

Strange. He gave it away.
He gave it to Thanos.

- Willingly?
- Yes.

- Why?
- I have no idea.

Maybe he made a mistake.

Or I did.

Strange is meant to be
the best of us.

So, he must've done it
for a reason.

I fear you might be right.

Thank you.

I'm counting on you, Bruce.

We all are.
