On Ten and Donna - I told you there would be fanwank! ;-)

There is a precedent for the redhead thing, of sorts - the Doctor himself has been disappointed about not being ginger - twice!

Like you, I thought the initial reference to Liz I was just Ten being, well, Ten and wittering on, (plus RTD being mischievous and giving us a reason for her being so pissed off with him at the end ot TSC) but even at the time, some people took it really seriously. It appears that Moff was one of them!
