Not really, the scene would go something like this... (Bob Newhart, eat your heart out

)
Doctor: "Sarah Jane! Lovely to see you again after so many years."
Sarah-Jane: "Sorry, do I know you?"
D: "It's me, The Doctor."
S-J: "Doctor? You've regenerated again?"
D: "Six times since I last saw you (Forget about The Five Doctors for a moment, Anoraks!)"
S-J: "Nice to see you again, your dress sense has... changed. Thats a very 1940s suit."
D: "Yeah, enough of that, listen, do you want a pound of sausages, genuine pork, sell 'em to you cheap, they fell off a lorry you see..."
OK, maybe not that last bit, but as we all know, she was there when JP changed to TB, so she wouldn't be surprised that he had changed.
