Flip Jackson

Philippa "Flip" Jackson was a companion to the Sixth Doctor.

She was riding on a London tube train with her boyfriend Jared in 2010 when it slipped through a temporal fissure to the sentient planet Symbios, where she met the Doctor. (BFA: The Crimes of Thomas Brewster)

In 2012, her mother had a boyfriend named Nigel, whom she considered "creepy." She was reunited with the Doctor when he was forced to swap bodies with Davros to thwart a Dalek attempt to alter the outcome of the Battle of Waterloo on 28 June 1815. Despite the Doctor's physical appearance in Davros's form, Flip nevertheless recognised the Doctor's good nature from her past meeting with him- even before she learned that the 'Doctor' was Davros, she assured him that he wasn't to blame for the deaths the Daleks caused while searching for him; subsequently helping the Doctor escape Dalek captivity and regain his original body. With her flat destroyed and her co-workers back home having been killed by the Daleks, Flip turned down the offer to return to the present with Jared in favour of spending more time travelling with the Doctor.
