Opinion: Will the Next Doctor Who be a Woman? | The Nerd Stash
The Master did it, after all, so why not the Doctor? We all know that Peter Capaldi will pass the TARDIS on to the next actor when he leaves Doctor Who after the current season, but we still don't know who that actor (or actress) will be.
