Doctor Who: 10 Ingeniously Tiny Clues To Big Plots

6. The Two Doctors

http://www.youtube.com/watch?v=6VxVOLRtjVg Ah, 'The Day of the Doctor' is an episode we can look back on. How long have we waited to say that? It seems like River was teasing the special even in 'A Good Man Goes to War', though.

RIVER: It's my birthday. The Doctor took me ice skating on the River Thames in 1814, the last of the great Frost Fairs. He got Stevie Wonder to sing for me under London Bridge.

RORY: Stevie Wonder sang in 1814?

RIVER: Yes, he did. But you must never tell him.

RORY: I've come from the Doctor too.

RIVER: Yes, but at a different point in time.

RORY: Unless there's two of them.

RIVER: Now, that's a whole different birthday.

Looking at the synopsis for 'The Day of the Doctor', at both Tennant and Smith combining forces, it's easy to assume that that's what River's teasing. No, she's probably not, but then again, Steven Moffat. That man seems to live on giving us all continuity ambushes and headaches, so it seems only natural that a throwaway line like this could come back in a big way.
