1987

On 7 November 1987, Pete Tyler, the father of Rose Tyler, was killed when he was struck by a car while crossing the road to a friend's wedding. This event was witnessed by an older Rose and the Ninth Doctor. Initially, Pete died alone before help could arrive. Rose created an alternative timeline by preventing him from being killed, which resulted in a dangerous paradox. After spending some time with his now-grown daughter, Pete learnt that for time to have continued normally, he must have died, so he ran in front of the same car. This time Rose was with him when he died. The fabric of time was altered so that the record showed Pete died while an unidentified woman knelt beside him. (TV: Father's Day)
