I obviously really want Billie Piper to be in the 50th anniversary. I miss Rose. I miss Doctor/Rose.
The implication of releasing David and Billie’s names at the same time is that they will have relatively equal roles in the story. It definitely implies that they will interact. I feel like it will be so enormously disappointing, in the way they have marketed the episode, if she does not have an adequate role in the story that it would warrant a legitimate complaint. I genuinely think that if Rose’s appearance is merely a cameo that people should complain about the marketing of the 50th anniversary. It just comes down to: don’t get people’s hopes up in the first place.
