Since then, Crossmore became a prison for the mentally insane. Director-general Swinton, along with senior staff; which include Warden Aimes, Dr Elle Whitby (daughter of NHS Trust Executive Director Dr Everett Whitby) run the facility. Wing F is the highest security housing area while Dr Whitby runs a reformation program in her wing at Crossmore for the psychological treatment of violent superhumans; which, due to high escape rate is the last chance to better Crossmore's reputation and restore its former budget.

Crossmore houses dozens of doctors and armed security personnel, features Class E Seclusion cells, observation pods (cells made from translucent polycarbonate), and has its own on site hospital.
