Yeah, she tells her secret name, but Annabeth says she's already forgetting all the Egyptian stuff and Sadie says she trusts her. Annabeth and Percy don't want to freak out the rest of CHB and also they don't want any campers to know about magic (watch Hecate's cabin have a mental breakdown) and they were gonna tell Chiron, but Chiron already knows probably.
