Donna Noble realised that she was bigger on the inside.

Amy Pond imprinted early on her Raggedy Man.

Clara Oswald saved the Doctor by being everything, everywhere, all at once.

The new series tagline Get Her Home is Belindas story arc.

As she tells him in theseries 15 trailer, shesnotone of the Doctors adventures.

It gives Belinda something to spark up against the Doctor.

She thinks theyre wonderful, and eventually admits it.

But its a different kind of buzz it stretches different muscles.

Its a performance thing too.

Janet Fielding did it brilliantly with Tegan.

Of course it means keeping the TARDIS away from modern-day Earth.

Normally, I think you should keep revisiting the present day its essential.

So its been a real challenge to avoid it for an entire series.

The series 15 trailer definitely shows modern-day Earth characters Ruby Sunday, Kate Lethbridge-Stewart, Mel Bush and more.

So does that mean their episode will be this series Doctor-lite adventure?

It just goes to show withDoctor Whothat theres always something new under the sun(s).
