Aboard the Wheel, Dr Corwyn worked as medical officer and psychiatrist, her quarters doubling for a consulting room.

Bill was allowed to keep his hobby and affectionately called her "Doc Corwyn".

Three years after her husband's death, Dr Corwyn tried to convince Jarvis not to destroy Silver Carrier, concerned that there might be life aboard. She examined the Second Doctor and Jamie McCrimmon upon their arrival, reporting to Jarvis that Jamie was lying about their presence on the Carrier, and introduced them to Zoe Heriot.
