My first thought when the 'song ending' bit came along was that the BBC may have been very stealthy in planning the next regeneration. I would vastly prefer this to Donna dying because, well, DO NOT WANT. Also, Astrid just died at Christmas! Sure, One lost two companions in a row way back when, but surely Ten has been through enough lately? I am worried after the seer's 'you have something on your back' remark last week, though. Wonder what on earth that was about?

Of course, the song ending may refer to something else entirely. I suppose we'll be waiting a while to find out about that and the incredible vanishing bees.

I agree that Ten/Donna is the most awesomest New Who team yet. He really, really does need someone to stop him and tell him off and give him hugs.
