Not much of a Dr Who fan, tho I occasionally watch it if there's nothing else on.
I'm not into spoilers so haven't bothered reading anything about the new doc.
But.. I reckon there's a good chance it's gonna be a woman(a first?)... that Sarah Jane or Sarah Jones or whatever her name was.... seemed strange to have so much focus on her and her son in the episode and then when we see her faced with two Daleks and she's got her arms up screaming no... they cut away and then there's nothing to follow it up.
Seems to me she would have died around the same time the doc is regenerating??
Or am I going cuckoo?
