"Doctor Who: The Doctor's Wife" Gallery!

Here's the latest set of images for this weeks new episode of "Doctor Who". The episode is titled, "The Doctor's Wife" and it's said that Suranne Jones's character is supposdly another possible Time Lord as The Doctor get's a distress call from a planet, which has a unknown Time Lord on it.
I thought it would be The Master, but seems as though it may be either Jones's character or the TARDIS above. As it's shown that we get to see the previous TARDIS interior design in this episode. So maybe there's a lost TARDIS in this episode and the above pics is it.
The whole wife in the title is unknown. Maybe Jones's character is the wife of The Doctor, but way back years ago, i.e. different time-line, different Doctor, who knows.
