DR. GALL. But I warn you. It’s dangerous. Come here to the window, my good fellow. Let’s have a look. Please give me a needle or a pin. (_Crosses up R. RADIUS follows. HELENA gets a needle from work-basket on table R._) HELENA. What for? DR. GALL. A test. (_HELENA gives him the needle. GALL crosses up to RADIUS, who faces him. Sticks it into his hand and RADIUS gives a violent start._) _Gently, gently._ (_Opens the jacket of RADIUS and puts his ear to his heart_) Radius, you are going into the stamping mill, do you understand? There they’ll kill you-- (_Takes glasses off and cleans them_) --and grind you to powder. (_RADIUS opens hands and fingers._) That’s terribly painful. It will make you scream aloud. (_Opens RADIUS’S eye. RADIUS trembles._) HELENA. Doctor-- (_Standing near couch._) DR. GALL. No, no, Radius, I was wrong. I forgot that Madame Domin has put in a good word for you, and you’ll be left off. (_Listens to heart_) Ah, that _does_ make a difference. (_RADIUS relaxes. Again listens to his heart for a reaction_) All right--you can go. RADIUS. You do unnecessary things-- (_Exit RADIUS L.2._) DR. GALL. (_Speaks to her--very concerned_) Reaction of the pupils, increase of sensitiveness. It wasn’t an attack characteristic of the Robots. HELENA. What was it, then? (_Sits in couch._) DR. GALL. (_C._) Heaven knows. Stubbornness, anger or revolt--I don’t know. And his heart, too. HELENA. What? DR. GALL. It was fluttering with nervousness like a _human_ heart. He was all in a sweat with fear, and--do you know, I don’t believe the rascal is a Robot _at all_ any longer. HELENA. Doctor, has Radius a soul? DR. GALL. (_Over to couch_) He’s got something nasty. HELENA. If you knew how he hates us. Oh, Doctor, are all your Robots like that? All the new ones that you began to make in a different way? (_She invites him to sit beside her. He sits._) DR. GALL. Well, some are more sensitive than others. They’re all more human beings than Rossum’s Robots were. HELENA. Perhaps this hatred is more like human beings, too? DR. GALL. That too is _progress_. HELENA. What became of the girl you made, the one who was most like us? DR. GALL. Your favorite? I _kept_ her. She’s lovely, but stupid. No good for work. HELENA. But she’s so beautiful. DR. GALL. I called her “Helena.” I wanted her to resemble _you_. She is a failure. HELENA. In what way? DR. GALL. She goes about as if in a dream, remote and listless. She’s without life. I watch and wait for a miracle to happen. Sometimes I think to myself: “If you were to wake up only for a moment you would _kill_ me for having _made_ you.” HELENA. And yet you go _on_ making Robots! Why are no more children being born? DR. GALL. We don’t know. HELENA. Oh, but you must. Tell me.
