No, Sophie has not met Danny Casey. It was all a figment of her fantasy and imagination. She narrate to her brother her chance meeting at the Royce’s where she recognized Casey and spoke to him first. She then asked him for an autograph for her little brother Derek but unfortunately neither of them had paper or pen. They went on to discuss the clothes at Royce’s windows and thereafter decided to meet next week and Casey had offered to then give her an autograph. Geoff did not really believe her and felt it unlikely that Casey would turn up at the appointed place.
