4. Is Rose Bad Wolfing?
While Rose was nowhere to be seen on the posters that were officially released back in September, the words 'Bad Wolf' can be seen to the left of Hurt amid the chaos he is walking through. Featuring normal Rose runs the same risk as Clara does, of needing to include the companion in some capacity while the story is focused on the Doctor. Bad Wolf Rose, however, is much more powerful and is linked to the Eye of Harmony in the Tardis itself, so could be an important part of the story. The trailers certainly suggests this. In the extended trailer we see her talking to Hurt, telling him "the Moment is coming" while the shorter one features her with some strange glowing eye action. The fact that Rose knows about the Moment and that Hurt is involved would seem to say that Bad Wolf Rose is at work. The very fact Hurt's Doctor exists should be news to Rose, so I would put money on her being a method of Tardis-Doctor communication in some way.
