“Father’s Day”, from the beginning, already came off as an episode that has some moral lesson in the end, the most dominant being “Be careful what you wish for.” Because you might just get it, plus a whole gang of Reapers. For the first time, we are confronted with real consequences of time travel. Now we see why even with the capacity, that the Doctor never involves himself in this kind of activity. Ultimately, this is an episode filled with repercussions that we can really relate to—the desire to defy and change particular points of time is natural for us; so while we understand where the Doctor is coming from, we also can’t help but sympathize with Rose, and even root for a happy ending.

Because Rose saved her supposedly dead father Pete, she has single-handedly created a wound in time. The presence of the Reapers who are trying to “clean” the wound satisfies the sci-fi element of the episode, but in its entirety, the issue is primitively Earth-bound. “Father’s Day” is a really important episode for Rose’s character, for the Doctor’s character, and for the entire Series 1—this really kills it when it comes to the sentimental repertoire of the show.

It deals with death, love, marriage, and self-sacrifice, which makes it very difficult for one to distance themselves and watch this episode objectively without not having a say in it in the end. This is an episode where the Doctor fully gives in to Rose’s humanity, by trying to save her father, and going as far as wanting to save the couple who was about to get married. It is also the turning point in Rose’s maturity, and also a great set-up for her character in “The Empty Child.” After “Father’s Day”, Rose is stronger, more courageous, and more assertive when it comes to what she wants and what she wants to do.
