Why did the author appear to be doing nothing at Gemini studios?

Sophie had requested her brother Geoff not to tell anything about her meeting with Casey. When Jansie asked Sophie about her meeting with Danny, Sophie was much amazed. She cursed Geoff for it because Jansie was ‘nosey’ and would spread the facts everywhere in the neighbourhood. In case her father knew about it, there would be a great row which her mother did not like. Sophie felt relaxed that Geoff did not tell about the date bit. She requested Jansie to keep it a secret.
