Aya is sick and in time she'll most likely get worse and will likely die if not treated. Aya's peers will probably be instructed not to respond to Aya unless she speaks as her "base" identity and to ignore anything stated by other identities as part of her treatment. That's assuming non-professionals are allowed to interact with her or that the strung out, emaciated wreck of a person with the deep circles under her eyes and the vacant gaze even is allowed outside of the clinic.

Welcome to the world of mental illness. It's a depressing and horrible thing.
