So, Matt Smith said that if he could have one companion back from the past it would be Rose.
Not because Rose is awesome, but because he and Billie Piper are mates.
And the entire world assumes THIS is a hint that Rose will be coming back.
WHAT?
Because Matt likes Billie?
News Flash: Everyone likes Billie. Except for a few crazy-obsessive shippers and original series fans who object to the Doctor loving Rose. Or find Billie doesn't suit their ideal of womanhood...by which they mean she isn't skinny enough or has big teeth.
So, perhaps I should say that everyone who WORKS with Billie loves her.
Notice these fellows being delighted by her return to work with them...
If Rose is returning, which is still unlikely, but not completely out of the questions due to David possibly returning, it should please both the hard-hearted original show dynamic shippers and the Ten2 people, because she and Ten2 would probably be together. This would give the closure that RTD refused to give to us during Journey's End.
I do doubt that Moff will throw we Doctor/Rose shippers much of a bone in a scenario that includes the return of David and Billie to the show. However, if he were going to please me, he would simply do a previously unseen flashback of Rose and Ten together doing something amazing to help the future Doctor. Also, bonus points if Rose says Eleven is cute.
Hey, a girl can dream, right?
