Seems like just a few days ago it was all over twitter that he was confirmed for 8, and now he's gone after teh '013 Xmas special. WTH?
I thought it was telling that the BBC's announcement of series 8 after "The Name of the Doctor" said nothing about who was involved except
for Steven Moffat. To be honest, at this point, I'm not convinced that Jenna will be involved past the Christmas special.
