Doctor Who

I'm the same, expecting it to be Bad Wolf related.

• The lack of "...as The Doctor".
• The regeneration effects looking different than normal, and massive.
• The quick glimpse back to the TARDIS console during the regeneration, after having dumped his regeneration energy into it.

Too many little threads indicating somethings not normal.

I'd be happy to have Doctor Piper (with a satisfying explanation), but I don't think that's happening - her char might be part of the season arcing plot. Credits didn't credit Billie as 'The Doctor '.
