..Billie Piper pulled out some good solid crying at the end. Glad she made it... sort of. That said - there is one thought - if there's a parellel universe then surely there's a parallel Doctor to go with it.
I think it's made clear that the Time Lords are beyond time and space quite a few times.
Also I thought the episode was better than I thought it would be, not happy that Rose and Co. survived though, would have been much better if they had all got killed messily.
The black Dalek pissed off, which means they'll pop back some other time. "LOL I HAEV CLONEZORED TEH DALEKS LOLOLO EXTERMINATE AM I RITE?"
TARDIS didn't save the day, "yay".
In closing, I'll watch the next series, but Catherine Tate can piss off. She's the most unfunny person in the world.
