[TheDoctorDonna]

I think PP is nearest to correct with this. The wiki page says:

This episode, perhaps more than any other in series 1, pointed out the utility of double banking. The experience of producing The Long Game would lead directly to the introduction of the Doctor- or companion-lite episode that was a consistent structural element of future series.

So wasn't actually Doctor-Lite itself. Thats the way I read it anyway.
