Shall I remember?

ALI

No.

JOHN

If I want to do anything different to what
I did, how shall I remember when I get back
there?

MARY

Don't. Don't do anything different, John.

JOHN

All right.

ALI

Choose just before the hour of the step
you desire to change. Memory lingers a little
at first, and fades away slowly.

JOHN

Five minutes?
