To say that there are many conspiracies flying around about the Doctor Who 50th Anniversary in the last week before the episode airs is a massive understatement. Not only are there rumours circulating, but there are also clips, promo shots and as of last week trailers all over the internet, giving us a taste of what's to come. One of the many things that people are excited about the Fiftieth is that Billie Piper will be returning, one can assume along with Ten. However, Im beginning to wonder if Billie Piper is returning as the character she played in series one and two. Billie and David were seen filming together, so we know that at least one point shes Rose, but the amount of times she's shown with John Hurt in the trailers has left me wondering. Could Billie Piper be playing someone besides Rose? Of course, Im talking about the way she spoke in her clips with John Hurt, and above all, the yellow that lined her eyes when she said ominious lines such as the moment is coming. This yellow tinge looked suspiciously similar to when she absorbed the Time Vortex, didnt it? Her run-in with the TARDIS's innards means there's plenty of room for interpretation regarding Miss Tyler, and in my opinion, there are three ways that this could play out.
