Doctor Who is about to undergo a change - only this time not in Doctor, but companion. In the series 9 finale, Clara Oswald (Jenna Coleman) left the TARDIS, setting off on her own adventures in a diner that travels space and time. The finale was followed by the Christmas Special where The Doctor (Peter Capaldi) was reunited with River Song (Alex Kingston), which proved a fun pairing since it was the first time viewers got to see the Twelfth Doctor and River interact.
However, now begins the long wait because Doctor Who won't return until Christmas 2016, followed by series 10 in 2017. When it does, Capaldi's Doctor will be teamed with a brand new companion. So far no official word has been given about who's been considered for the role, but already some rumors have named EastEnders actress Rakhee Thakrar. At this point, Thakrar even being on their radar is just speculation, but Capaldi did recently reveal in an interview with the Brazilian website Omelete that his series 10 companion has in fact been cast.
"There will be a new companion, along any minute," Capaldi told Omelete, "which I'm very excited about, 'cause obviously I know who that is and we've been doing a bit of work together already and it's very exciting." Since Doctor Who won't air until late this year, the work Capaldi has been doing with his new companion is unlikely any filming for the Christmas special. Instead, they probably worked together through audition readings or even a screen test. Nonetheless, it seems that Doctor Who's latest companion will be announced very soon.
Though Capaldi is obviously forbidden to name any names, he did share a significant detail of how his new companion will differ from Clara:
"Clara had prior knowledge of the Doctor. 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."
While at first it seemed strange that Clara continued traveling with the Twelfth Doctor, considering how fundamental she was for the Eleventh Doctor's final adventures, throughout the course of their partnership Capaldi and Coleman proved a smart match. Their parting of ways was tinged with sadness in the way only Doctor Who can manage without actually killing anyone, and given that the Twelfth Doctor's memories were altered, it's unclear just how he'll react to a new companion.
Doctor Who will continue with a Christmas special in December 2016. Season 10 is slated to air in 2017.
