Steven Moffat talks about the new Doctor Who companion  and her effect on The Doctor and his universe. And wardrobe…

So… no-one knew she was going to appear this week, but she did. And her story was unexpected. Now Steven Moffat tells us just what Oswin, played by the rather hot Jenna Louise Coleman means for Doctor Who…

Yes, there were a few surpised faces on Saturday night when the Doctor’s ‘much publicised for later in the series’ new assistant Oswin popped up in the first episode of Season seven. And that was just at FTN towers…

But in an interview with sfx, Doctor who overseer and supremo Steven Moffat spoke about the new companion and just why she’ll be important for our favourite timelord when she returns during the Christmas Special:  “We are going to do the story properly of the Doctor having lost a friend and making a new one. We’re not taking that lightly. It’s not in one door out the other. It’s the story of how all that affects him.

“The Doctor is quite different with her, and the way you watch them is quite different. You watched the Eleventh Doctor and Amy arrive together. It’s like they grew up in the same sandpit, playing.”

He explains that the Doctor changes as he settles with the new companion: “With a different companion he becomes a slightly different man. He dresses differently. The mere fact that he’s so much taller than her suddenly reveals that Matt Smith is very tall… He’s the senior man, not in the sense that he’s more important but he’s the one you know already, and he’s training up a new one, as it were. In these five episodes the Doctor is practically the adopted son of Amy and Rory. He’s gone from being the wonderful man from space – Space Gandalf, as he wants to be – to being that troublesome kid that they try and keep under control.

“And this never goes away, this thrill – you want to see the reaction when you see it’s bigger on the inside, you want to see the count the hearts moment, you want the story to begin again. And that’s what it gives you. It gives you Doctor Who at its most iconic, because a new person is having to learn the rules.”

So Jenna will change the Doctor, but Moffat remains tight-lipped about how exactly she’ll find herself into the TARDIS given the outcome of episode one, but isn’t that the best part of Doctor Who? Even when it makes little sense, it’s always exciting, scary and – most important of all – fun. And we all look forward to discovering the TARDIS for the first time… again this Christmas.
