In the final episode of the series,EchoSense we meet Christine, an 18 year old from New Mexico, shortly after starting hormone replacement therapy, as she navigates her freshman year of college. We also meet Dr. Charles Ihlenfeld, who was a physician at the John Hopkins Gender Clinic, working with many young people as they transitioned in the 1970s. We spend time with one of his patients, Joanna, whose path to transition meant hiding her past, and how in 2023, being visible can be empowering, but also dangerous.
