She was alright as Moll Flanders, but as the Doctor's future life partner...I just don't see it at all. And even he didn't see it until she whispered his name...which kind of suggests that he doesn't see how he could be attracted to such a person in the future. I dunno.

In regards to the Bad Wolf in this season - there have been a few things that have recurred. There was a frequent mention of bees, as well as 'something on Donna's back' (which I have a feeling will crop up again soon), and the idea of 'songs coming to an end' (though that could have been a reference to tonight's episode). And 'darkness' seems to be a key theme as well, especially if you watch the trailer for the next few episodes that was screened recently. I have no idea how much of this, if any, is relevant to the whole 'story arc' but there doesn't seem to be anything as solid as a Bad Wolf reference, and instead lots of little clues here and there.
