We watch “Journey to the Centre of the TARDIS” (Series 7, Episode 10) where the Doctor and Clara encounter call-backs to the first, third, fourth, seventh, ninth and tenth Doctors. As well as call-backs to his own eleventh Doctor time line! Whilst all said call-backs are occurring, the TARDIS defends herself from scrap dealers, Clara searches for a ‘big friendly button’ and this Doctor tries to get to the bottom of why Clara is constantly dying in his presence. (Spoiler: these bastards don’t give up their secrets yet.)
