Her development is subtle but significant, evolving from a background authority figure into a trusted confidante who understands the unique pressures faced by her elite students. Key moments often involve her gently guiding them back to reality, offering wisdom that helps balance their high-stakes emotional games with the responsibilities of adolescence.
