I'll get this out of the way straight-off. I'm not a fan of her work in general. There's just something grating about the characters she's created for her show. And that certainly applies to Donna - for the first fifteen minutes or so of the introduction. It's such a powerful approach which she takes that I think that's what was seared into the minds of the viewers who had negative comments about her. By the end of the episode, she had begun to mature, and she promised the Doctor as they said their goodbyes that she would go out into the world and be magnificent.
It will be this new Donna who will be rejoining the Doctor, not the shrill Bridezilla termagant we first met.
Still, as I said earlier, I'm not that big a fan and I'm not looking forward too much to seeing her every episode. However, I'm willing to give RTD (mostly his other writers) the benefit of the doubt when it comes to writing the role. We'll see how it goes.
Anyhoo, that's not what I'm on about today. It was during her introduction scene that an exchange of dialogue came up which made me wonder if it was a harbinger of what would come later in the third season.....
THE DOCTOR: Are you human?
DONNA NOBLE: Is that even an option?
THE DOCTOR: It is for me, yeah.
At the time I first watched "The Runaway Bride", I think I considered that a reference to his supposed human genetic background. (I'm still of the belief that as part of his personality quirks, the Eighth Doctor was lying to Grace about his mother being human just so he could shag her.)
But now, having seen the two-parter "Human Nature"/"Family Of Blood", maybe it was a clue about the Chamelion Arch feature of the TARDIS and its function. If so, then it was a very subtle layout for the groundwork so that in hindsight the Chameleon Arch no longer looks like it was a plot device pulled out of the hat at the last moment.
Or I could just be reading more into it than intended. That's usually how I operate.....

That really out to be in my job description as a televisiologist!
