IN A BUSTLING ALIEN MARKETPLACE, DONNA NOBLE is separated from the Doctor and lured into a fortune teller’s booth. The fortune teller sees a man in Donna’s life who changed everything. Asked what led to that meeting, Donna remembers the choice that saw her turn left in her car to start her job at HC Clements… but what if she turned right? An unseen creature crawls onto Donna’s back, to the fortune teller’s delight: “Turn right and never meet that man. Turn right and change the world!” Now working for Jival Chowdry, Donna is on a Christmas Eve girls’ night out when a star appears over London, attacking the city. Donna watches the star being destroyed, but is confused when her friend Alice says there’s something on her back. Running off, Donna overhears a UNIT soldier reporting the death of a man called the Doctor, then meets a young woman who is shocked at this Doctor’s demise.
