She was riding on a London tube train with her boyfriend Jared Ramon in 2010 when it slipped through a temporal fissure to the sentient planet Symbios, where she met the Doctor. (AUDIO: The Crimes of Thomas Brewster)
She took a first aid course but she claimed that it made her feel ill.
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 18 June 1815. Despite the fact that the Doctor was in Davros' body, 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 she helped 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.

After a series of travels in the TARDIS, she became separated from the Doctor in orbit around Earth in 2071, and almost became host to a piece of alien space debris named "Scavenger". After teleporting from its grasp with seconds before her absorption, she became trapped floating in space once again. Realising she was running out of Oxygen, she recorded a message for the Doctor and used her spacesuit thrusters to propel herself to Earth, to either await rescue, or die in the attempt. (AUDIO: Scavenger)
Later, when the Doctor met an older version of Peri Brown on the planet Krontep, she asked about Flip, whom a weakened version of the Doctor, created by a mind parasite in her mind had mentioned. He told of her fall to Earth, but revealed that he'd used the TARDIS to bend space and time, slowing her descent to a few hundred metres, thus saving her. He then further revealed that he'd received an invitation for her and Jared's wedding, implying that he had returned her to her native time of 2012. After Peri declined his offer to attend the wedding with him, he vowed to return for her, one day. (AUDIO: The Widow's Assassin)
