Certainly a ok start (aside from the musical bit, why does everyone have to spoil episodes like this).
So far they seem a good team up, but I like Ruby a lot more than I like the [new] Doctor, maybe he'll grow on me.

Theories ?
The old woman is an alien (time lord ? master ?).
She may also be (or know) the woman who dropped Ruby off 19 years ago ?

I think maybe the Rani. However I feel she is definitely the one who waits who was referred in the specials.
