Yes, I think many T's are well aware of being alert to signs and symptoms even if they are not told straight up, but given nuances and hints. If you bring evidence, they should have a good solid grasp of trauma staging and ways to address the complexities, as well as let you know what they do and do not have to report. If you are subtle, they might know, but choose to honor your timetable and bide time. IMO a seasoned clinician has a nose and considers many things.

My T goes in wake up mode with me if I say anything to minimize the degree of sa in childhood, and will usually have a fresh "shock and awe" term to make me face reality- aka the crime scene, the cult, the torture chamber- bc I have an embedded need to minimize. He is all about pediatric records and plain speech. He is very twofold about defenses- which creatively keep people safe but skew or distance the harsh truth from the "antiseptic of daylight".
