Oswin Oswald...

OK...so who is Oswin Oswald?

Quite a mystery is the new companion of the Doctor.  To use a phrase the Doctor said himself "...she shouldn't be."  How is the "girl twice dead" still alive in another time.  Yet another great paradox of the Doctor who series.

Or...is the show really going backwards in time?

The first time the Doctor meets Ms. Oswald, he says he is 1200 years old...but the next time he meets Clara he states that he is only 1000 years old.  And in Aslyum of the Daleks, she was a genius, but in The Bells of St. John, she knew nothing about computers...

One could really be pulling at strings here...or has Steven Moffat hidden clues along the way for the past few seasons...much like the "Saxon" references and "Bad Wolf", which spanned more than 3 seasons in some instances if I am correct (all depending on how you look at time travel of course).

So, what is the reference to "The Rose and the Crown"?  It must surely be in reference to Rose Tyler.  And the "pond" where the Governess fell in and drowned...was frozen until the pond thawed - surely a reference to "Amy Pond".  So, I can be quoted here...I don't believe we have seen the last of Amy and Rory.

But yet who is Oswin?
