Posing the questions may be unethical, however, as long as the questions are not directly specifying details about the patient, then it would not violate the confidentiality (I think) and is still inside the freedom of speech.

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.

Now, TELLING the father of the patient's progress and such I do believe is not only unethical but may also be illegal. Even if you make it as a question, such as: "[Patient] has been seeing SARC for 10 months, correct [father's name]?", is a breach of confidentiality.
