This post contains spoilers up to the end of the latest episode again, Flesh and Stone.

Okay, well, as Camilla and I were talking theories in the last post, I rewatched the episode to see if I could make more sense of things, and I noticed something that was either a huge gaffe by the producers, or ... incredibly significant to this season's plot.

In the scene in the forest, the Doctor is without his coat. He lost it to the angels in the last room. He's wearing his shirt with the sleeves all the way down his arms. He tells Amy, whose eyes are shut, to wait there for him. He rushes off while she's frightened.

A moment later we see the Doctor's hands reach back into the frame to take Amy's. The sleeves are rolled back to his elbow, and in the following sequence we can clearly see that he's wearing his coat. He comforts Amy and implores her to remember something he told her when she was seven. He seems quite serious, and tells her that the point is that she needs to remember. He kisses her forehead tenderly and leaves.

Then we cut back to River, the army guy, and the Doctor hurrying through the forest. The Doctor has no coat.

Unless this is just a gaffe, and it seems deliberate enough not to be, there's another version of the Doctor running around. There are two of them.

Perhaps a future version, flitting about using the cracks in time to try to set things up so that the good guys can win. Perhaps this is why the bad guys keep referring to the Doctor as "the Doctor in the TARDIS" ... maybe there's a Doctor without a TARDIS too.

This could also explain how someone taught River Song to drive the TARDIS. She tells the Doctor that he was away that day, when she learned. Perhaps she meant that a different version of him taught her, in a world where two of them existed.

Perhaps this is also how she can end up killing the Doctor -- she simply kills one version of him, while the other continues to exist?

I don't know all the whats and the whys and the whens, or how it fits in with the fact that the Doctor keeps missing things, but I'm looking for some reassurance from other Doctor Who fans that I'm not just seeing things. Something is up here. Moffat is being very clever.

Here is a helpful transcript I wrote up. Shirt Doctor is distracted and tells Amy she'll be safer here and he'll be back, then he sort of casually/awkwardly pats her head and hurries off, calling for River.

[Amy]: Yeah ... later ...

[We don't see Jacket Doctor enter, but his hands, sleeves rolled up, reach in and take Amy's]

[Jacket Doctor]: Amy ... you need to start trusting me, it's never been more important.

[Amy]: But you don't always tell me the truth.

[JD]: (smiles) If I always told you the truth, then I wouldn't need you to trust me.

[Amy]: Doctor ... the crack in my wall. How can it be here?

[JD]: I don't know yet but I'm working it out. (looks significantly toward where Shirt Doctor left us, then back to Amy) Now, listen. Remember what I told you when you were seven.

[Amy]: What did you tell me?

[JD]: No. (squeezes eyes shut and touches his head to hers) No, see, that's not the point. You have to remember.

[Jacket Doctor kisses her tenderly and goes. We don't see where he leaves to.]

Amy: Remember what? Doctor?

[Cut back to Shirt Doctor, with River and the army guy]
