[He crosses over to her by means of stepping-stones below the cascade.
PROFESSOR RUBEK.
Where have you been all day, Irene?
IRENE.
[Pointing.] Far, far over there, on the great dead waste--
PROFESSOR RUBEK.
[Turning the conversation.] You have not your--your friend with you to-day, I see.
IRENE.
[Smiling.] My friend is keeping a close watch on me, none the less.
PROFESSOR RUBEK.
Can she?
IRENE.
[Glancing furtively around.] You may be sure she can--wherever I may go. She never loses sight of me-- [Whispering.] Until, one fine sunny morning, I shall kill her.
PROFESSOR RUBEK.
Would you do that?
IRENE.
With the utmost delight--if only I could manage it.
PROFESSOR RUBEK.
Why do you want to?
IRENE.
Because she deals in witchcraft. [Mysteriously.] Only think, Arnold--she has changed herself into my shadow.
PROFESSOR RUBEK.
[Trying to calm her.] Well, well, well--a shadow we must all have.
IRENE.
I am my own shadow. [With an outburst.] Do you not understand that!
PROFESSOR RUBEK.
[Sadly.] Yes, yes, Irene, I understand.
[He seats himself on a stone beside the brook. She stands behind him, leaning against the wall of rock.
IRENE.
[After a pause.] Why do you sit there turning your eyes away from me?
PROFESSOR RUBEK.
[Softly, shaking his head.] I dare not--I dare not look at you.
IRENE.
Why dare you not look at me any more?
PROFESSOR RUBEK.
You have a shadow that tortures me. And I have the crushing weight of my conscience.
IRENE.
[With a glad cry of deliverance.] At last!
PROFESSOR RUBEK.
[Springs up.] Irene--what is it!
