By now most of you reading will have heard that Amy and Rory are slated to leave the show in Series Seven. The initial announcement, on 15 Dec 2011, stated that their story would be coming to a “tragic” end. Much as I love Rory (and don’t actively hate Amy), I’m ready for them to go. Here’s why.
First, Amy’s tenure on the show is unprecedented in post-Hiatus Who. Until the arrival of Eleven and Amy, there was a change in either Doctor or Companion (or both) at least every series. Though I found it slightly galling at the time, longing for a bit more stability, it kept things “fresh,” and I find that now the TARDIS crew is getting slightly stale. Three series is quite a lot, actually, and that’s borne out by reviewing the pre-Hiatus TARDIS crews, too.
Look at the longest tenure record-holders. According to the TARDIS Index File, we can consider individual episodes (in which Jamie comes out on top, with 113), total stories (Rose, with 26, including the Children in Need special and two “substantial” cameos), or calendar time (Tegan, just shy of 3 years, with Sarah Jane only a couple of weeks behind). Amy is fast approaching these latter two marks.
