Amy & Rory Pond (né Williams) were the first real couple to travel in the TARDIS since Ben & Polly (sorry, Mickey). Their presence (along with frequent appearances by River Song) gave the show a real family feel in seasons 5 through 7. Whether it was Rory standing guard over Amy trapped in the Pandora for two thousand years, or Amy sacrificing her future to live with Rory in the past, no two companions epitomised true love more than the Ponds.
