Romana (Doctor Who)
Romana II enjoys a more intimate relationship with the Doctor than her first incarnation, some fans have assumed that she had a romantic relationship with the Doctor. Although a relationship was never shown or intended by the writers. In many ways, she is the companion most like her Doctor - besides being of the same race and close to the same intelligence, she occasionally mimics his sense of style, wields her own sonic screwdriver and can occasionally get the better of him in moments of banter and more practical situations. As her practical experience develops, she also becomes more assured and capable in the situations she finds herself in.
