TARDIS (The Name of the Doctor)

The First Doctor and his graddaughter nearly stole a faulty TARDIS when leaving Gallifrey (TV: The Name of the Doctor) to escape The Hybrid. (TV: Hell Bent) However, an echo of Clara Oswald appeared and told him he was making "a very big mistake" by stealing the wrong TARDIS. She convinced him to steal a TARDIS with a "knackered" navigation system that would be "much more fun". (TV: The Name of the Doctor)
