Jo Grant

Josephine Grant was placed in UNIT, against the Brigadier's wishes, by her Uncle - a high-ranking official in the UN. The Brigadier decided that Jo could replace Liz Shaw, who returned to Cambridge, as the Doctor's research assistant. Secretly hoping that the Doctor's attitude would put Jo off UNIT, the Brigadier tells the Doctor that Jo will be an admirable assitant.

Character Description
Jo's first meeting with the Doctor doesn't bode well for the future, as she mistakes an important experiment for a fire and ruins it by dousing it with a fire extinguisher. Despite this initial clumsiness, her failures fuel her enthusiasm, and she becomes more determined to prove people wrong about her. So much so, that, after recovering from being hypnotised by the Master to kill the Doctor, she disobeys orders and follows the Doctor to Rossini's Circus, and is able to rescue him.
