The new Doctor Who companion has been cast – and according to Peter
Capaldi, Jenna Coleman's replacement could be announced very soon...

"Clara had prior knowledge of the Doctor," Capaldi told Brazilian website Omelete.
"It was conceived as a human connected to your timeline, and so had
access to the cosmic nature of the Doctor. She understood a little about
how he was. And as she was already with [Eleventh Doctor] Matt [Smith],
she knew the Daleks and the TARDIS. Now we have someone who knows very
little about the Doctor."
