The Doctor hasn’t had a steady companion since Donna Noble was forced to depart in the series 4 finale, “Journey’s End,” when she became a Time Lord/human hybrid, which unfortunately began to kill her. The Doctor was forced to wipe her memory in order to ensure her survival, though he would never be able to speak to her again, lest she remember and her mind destroy itself.
Sure, he had a few companions here and there: Jackson Lake in The Next Doctor, Lady Christina de Souza in Planet of the Dead, Adelaide Brooke in The Waters of Mars, and Wilfred Mott in The End of Time were each one-off companions, who only assisted the Doctor in full capacity for one episode. So when is the Doctor going to get a steady companion?
Well, now that the Tenth Doctor has regenerated into his eleventh incarnation, there’s of course going to be a new companion. And that new companion is Amy Pond (Karen Gillan). Of course, as the fifth series has not yet premiered, not much is actually known about Amy. All we have to base her upon are set photos and spoilers.
Set photo-wise, there’s a picture of her wearing a policewoman’s uniform. She doesn’t quite seem like she belongs in the uniform, so this spoiler makes a bit of sense. The Sun reports that though “everyone thinks she is this prim and proper policewoman… it’s going to be revealed early on that she works as a kissogram.”
“It’s going to be a bit of a shock for the fans, but I think they’re going to enjoy it. Amy Pond’s a really strong character and Karen is great in the role.”
This development (a far shot from the shopgirl, doctor, and socialite that the Doctor has previously shared the TARDIS with) has been attributed to the new, edgier showrunner Steven Moffat. “Moffat’s an edgier writer and the show is going in an exciting new direction,” the Sun reports.
