Read this passage carefully, and then answer the question that follows it: John: What about the way your father looks at me! Tell me, are all your family as scared of him as I am? Catherine: Dickie is, of course; and Ronnie, though he doesn't need to be. Father worships him. I don't know about Mother being scared of him. Sometimes, perhaps. I'm not-ever John: You're not scared of anything, are you? Catherine: Oh yes. Heaps of things. John: Such as? Catherine [with a smile]: Oh... They are nearly all concerned with you. [RONNIE looks cautiously in at the French windows. He now presents a very bedraggled and woe-begone appearance, with his uniform wringing wet, and his damp hair over his eyes.] John: You might be a little more explicit... Ronnie [in a low voice]: Kate! [CATHERINE turns and sees him.] Catherine [amazed]: Ronnie! What on earth- Ronnie: Where's Father? Catherine: I'll go and tell him- [She moves towards the door.] Ronnie [urgently]: No, don't; please, Kate, don't! [CATHERINE stops, puzzled.] Catherine: What's the trouble, Ronnie? [RONNIE, trembling on the edge of tears, does not answer her. She goes to him.] You're wet through. You'd better go and change. Ronnie: No. Catherine [gently]: What's the trouble, darling? You can tell me. [RONNIE looks at JOHN.] John You know John Watherstone, Ronnie. You met him last holidays, don't you remember? [RONNIE remains silent, obviously reluctant to talk in front of a comparative stranger.] John [tactfully]: I'll disappear. Catherine [pointing to the dining-room door]: In there, do you mind? [JOHN goes out quietly.] Now, darling, tell me. What is it? Have you run away? [RONNIE shakes his head, evidently not trusting himself to speak.] What is it then? [RONNIE pulls out the letter from his pocket and slowly hands it to her. CATHERINE reads it quietly.] Oh, God! Ronnie: I didn't do it. [CATHERINE re-reads the letter in silence.] Kate, I didn't. Really, I didn't. Catherine [abstractedly]: No, darling. [She seems uncertain of what to do.] This letter is addressed to Father. Did you open it? Ronnie: Yes. Catherine: You shouldn't have done that- Ronnie: I was going to tear it up. Then I heard you come in from church and ran into the garden-I didn't know what to do- Catherine [still distracted]: Did they send you up alone? Ronnie: They sent a Petty Officer up with me. He was supposed to wait and see Father, but I sent him away. [Indicating the letter] Kate-shall we tear it up, now? Catherine: No, darling. Ronnie: We could tell Father term had ended two days sooner- Catherine: No, darling. Ronnie: I didn't do it, Kate, really I didn't- [DICKIE comes in from the hall. He does not seem surprised to see RONNIE.] Dickie [cheerfully]: Hullo, Ronnie, old lad. How's everything? [RONNIE turns away from him.] Catherine [to DICKIE]: You knew he was here? Dickie: Oh yes. His trunks and things are all over our room. Trouble? Catherine: Yes. [from Act 1 Scene 1] In what ways does Rattigan make this such a dramatic moment in the play?
