ST and Mary are Londons worst couple, obsession at first sight after a chance meeting at the Magnus Institute. They are locked in eternal lustful hatred, their equally matched power levels keeping them from killing each other but not from trying. They are each others worst fear and they are loving every second of it, to a degree that they even get a shared domain after the eyepocolypse. Regrettably their mutal obsession does not contain their fear avatar impulses and they often challenge each other to traumatizing random people.
