Well, here it is. Two more companions take one last trip in the TARDIS. I promised a theory on Amy Pond, and it’s time to share it below.
In short, the Doctor, Amy, and Rory are visiting Manhattan when suddenly, Rory finds himself zapped back a couple decades. Time around Manhattan is weird, but a novel Amy is reading, one that it turns out is written by River, basically points the pair to where Rory went. The whole thing is set up as a trap where the Weeping Angels keep prisoners in a special apartment building to feed off of, and they’re so powerful that they are taking over all the statues in the city. Yes, including Lady Liberty. So, I guess they aren’t always statues? Or something?
Whatever. Rory is the next victim, and if they can create a paradox, the chronal energy will somehow destroy the Angels and send everyone back where they came from. They do that by having Rory essentially die in two places at the same time. But there was one Angel back in the present left to zap Rory, and Amy wants to go back with him so he doesn’t die alone in the past. The Doctor can’t bring her back in the TARDIS because, well, she was special and born to fix time so the rules are different. She goes anyway, leaving a note in the back of River’s book saying that she and Rory are fine, but he better get a new companion because he gets weird otherwise, and maybe he should go visit young Amy again.
No, River will not be a permanent companion.
So, yes, that was the sudden departure of the couple the Doctor called “the Ponds” from the TARDIS. What does all this have to do with Amy?
Simple: as I see it, the Doctor was Amy’s childhood friend, and Rory, well, Rory is the man a mature Amy settles down with.
It makes a certain amount of sense. Amy is wearing reading glasses now, showing her age, and we’ve seen episodes where she has actual jobs and the like. This Doctor is incredibly immature, someone who can bring comfort to a little girl, but not someone a mature woman would necessarily want a relationship with. He’s good for the occasional visit, but not for long term things. But Rory is the man who will guard her for 2,000 years, and while he was often treated as Amy’s companion as opposed to the Doctor’s, he was also always up for an adventure on his own. He probably became a nurse because she adored a Doctor, and he was generally nonplussed about life with the Doctor, the first to ask the basic questions that didn’t occur to any other companion before and one of the few not to be surprised the TARDIS was “bigger on the inside than on the outside”.
Rory is a dependable man, someone to settle down with. The Doctor is, well, he doesn’t settle anywhere, and at some point, Amy moved beyond fish sticks in custard and into something like adulthood. That’s where she’d need a Rory.
And he could keep up with her and the Doctor. Even if the Doctor treated Amy as his closer friend, it was never more than a friendship in many ways. Rory loved her, she loved Rory, and the one time she did throw herself at the Doctor, he pushed her away since that even by Doctor standards, this one seems rather uninterested in sex.
So, that was that. Amy grew up, and as a result, she didn’t need her childhood friend any more.
Not a bad character arc for a companion.
Now, this Doctor needs to find someone else to stick to, or he’s going to be a real problem for the universe.
