You do know, though, that Smith's lines in End of Time were written by Moffat himself, right?
RTD only wrote for the Eleventh Doctor when he guest-starred in The Sarah Jane Chronicles episode, Death of the Doctor.
I did not know that...................
You mean Sarah Jane Adventures
While I don't particularly like SJA, that episode was one of the better ones. Both of the ones with the doctor in were good. Plus Jo came back too!
