Apparently there may be a scene (just one) filmed later this week that includes David Tennant and Billie Piper who are supposedly listed on the Call Sheet as "The Other Doctor" and "Rose Smith".
The scene is 165 which is after the bookstore scene, and very near the end of it all... perhaps right around the time a regeneration would happen??
So will it be Rose and 10.5 turning up to say goodbye? Or helping with the regeneration? Or perhaps it'll just be a reaction shot - since 10.5 is linked to 10 perhaps he just feels when 10 is regenerating?
Who knows, but another rumour thats been hinted at is that the Doctor regenerates alone in the TARDIS - so no companion will be with him.
Obviously these are just rumours at the moment, but if its true then I wonder when Martha will be turning up - they can't really just leave her out can they?
