She remained with the Doctor after his regeneration into his sixth incarnation, but found it harder to get along with him becauase of his newfound arrogance. She was separated from him by the Time Lords so that they could cover up the Ravalox conspiracy. According to the Master, Peri ended up wed to King Yrcanos.
