Doctor Who: The Timey-Wimiest Episodes Not By Steven Moffat
6. Father's Day (2005)
Way back in the first series of the revived Doctor Who, the show brought us a little character-driven gem called Father’s Day.
In this story, the Ninth Doctor does Rose a favor and brings her back in time to the day her father died in a tragic accident. To make matters more complicated, they actually do this twice.
Unfortunately, Rose is overcome with emotion
and interferes not only with the original events, but with the earlier version
of herself and the Doctor as well. This
causes a fracturing in time, and releases creatures called the Reapers who are
drawn to the damage, threatening everyone.
In all of this, the episode points out the futility of attempting to interfere with past events in one’s own life, adding to the show’s whole sense of how time travel supposedly works.
In the end, the Doctor sacrifices himself to protect all the others involved, and Rose’s father undoes his daughter’s interference, allowing himself to die so that time can be repaired.
