November

 * 7 - Pete Tyler is killed when he is struck by a vehicle while crossing the road en route to a friend's wedding. This event is witnessed by Rose Tyler and the Doctor. Initially Pete died alone before help could arrive. Rose creates an alternate timelines by preventing him from being killed, which results in a dangerous paradox. Ultimately, after spending some time with his now-grown daughter, Pete learns that in order for time to continue normally, he must die, so he walks in front of another vehicle. This time Rose is with him when he dies, and the fabric of time is altered so that the record shows Pete died as an unidentified woman knelt beside him. (DW: 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.
