Weeeeeeeeeell...in the TVM Eight says he's half-human. Whereas when Donna becomes a half-Timey/half-human, it makes her brains start coming out of her ears. Now obviously there is all kind of handwaving (ho-ho) that can be done regarding how she got to be a timey-human (I think there was some technobabble in there about how the particlar micro-doodah transfer thingumajig in particular couldn't be sustained, but I was a bit busy blubbing by then to be paying close attention), so as with all canon it's kind of pick'n'mix. Just wondered if Rusty was inviting another round of 'Paul McGann doesn't count'...

I'm still all wibbly. Oh, Donna, I miss you already.
