I'm not a Claudia fangirl, and I don't see her thinking she's the center of her own world. If she truly thought that, she wouldn't have hacked into the Warehouse to help get her brother loose. She also wouldn't have freaked out when Leena & Mrs. F thought she was MacPherson's stooge. She also wouldn't be so worried about Artie getting hurt.
I prefer to be called Sunny, Sun or SK. Thanks.
