Think about this:

Anton

Vincent... Vincent...

Where's the shore? We’re too far out...

Vincent

You wanna quit?

Anton

We’re too far out!!!

Vincent

You wanna quit?!?!

Anton

No!

...

Anton

Vincent!.. How are you doing this, Vincent?

How have you done any of this?

We have to go back.

Vincent

It's too late for that, we're closer to the other side!

(Anton looks towards the empty horizon)

Anton

What other side?

You wanna drown us both?!

Vincent

You wanna know how I did it?

This is how I did it, Anton:

I never saved anything for the swim back!
