Events
On Jackie Tyler's 40th birthday in 2007, the Doctor's TARDIS fell into Pete's World, where it nearly died. With twenty-four hours before the TARDIS could return to its home universe, Rose Tyler discovered a living version of her dad, Pete Tyler, alive and a successful businessman. To meet her "father", Rose snuck, with the Tenth Doctor, into the birthday party of that reality's Jackie Tyler. The President of Great Britain forbade the use of John Lumic's new cybernetic lifeform, but Lumic ignored him. Mickey Smith, mistaken for his parallel self, Ricky Smith, was taken by the Preachers, who fought Lumic. The cybernetic life, dubbed Cybermen, attacked Jackie's party, killing most of those inside, including the President. (TV:, PROSE: )
