Asking the father: "how long has [patient] been seeing the SARC and working with the SARC for?", that would be a breach of confidentiality. However, asking: "what kind, if any, hallucinations does [patient] experience" is not a breach of confidentiality (hypothetical question, Teary may not have hallucinations but hopefully you get the idea). The first question may be unethical, second question I think is ethical.
