Take this tidbit with a T-R-E-M-E-N-D-O-U-S grain of salt, but there has been a widely circulating rumor out there that stemmed from a UK fanforum regarding Season Four, and any possibility of seeing Annie/Mitchell on screen together again. Apparently, the rumor was started by someone who claimed to be on set during an unspecified date, and saw Aidan filming several scenes from the new season with Lenora. And they are quoted as saying "Annie and Mitchell fans will be chuffed." (Chuffed - i.e. extremely excited, happy, proud, etc.)
I really want to believe this, and the track record for rumors regarding this show has been really good lately - remember last season and the promise of a heartbreaking scene between our signature couple in episode five? Boy, was that an understatement - but it did turn out to be true. At the same time, how would Aidan fit in time to fly to the UK and film? I'm willing to think his schedule might have allowed it since he's a secondary character in The Hobbit.
Anyway, theories? Do you think it might be true?
