I’ve been re-watching Doctor Who with my wife recently. She didn’t start to get into the show until the later part of the David Tennant years. I would make references to things she hadn’t seen, forgetting for a moment that she didn’t know what I was talking about. Last night we got to the end of Series 2, where the Doctor and Rose say goodbye. Just as it did the first time, re-watching that two-parter brought tears to my eyes. Though I like Martha Jones, Donna Noble, Amy Pond, and Clara Oswald, Rose Tyler will always be my favorite companion. Who’s your favorite companion?
