July

November

 * 7 - Pete Tyler was killed when he was struck by a car while crossing the road to a friend's wedding. This event was witnessed by Rose Tyler and the Ninth Doctor. Initially Pete died alone before help could arrive. Rose created an alternate 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 as an unidentified woman knelt beside him. (TV: Father's Day) Technically, since Rose being with Pete becomes part of established time, the alternate timeline is in fact now the one where he dies alone.
