  • Trivia

    • The Doctor: Cos' quite by chance, I'm still within the first 15 hours of my regeneration cycle. Which means I've got just enough residual cellular energy to do this. [holds out arm and hand regrows].

      Though the "15 hours" revelation was a new piece of the Doctor Who legend, this is not the first time we have seen evidence that a Time Lord body does not "Set" immediately after a regeneration. In the original series "Destiny of the Daleks" Romana is seen regenerating, changing her looks several times before settling on the appearance of Princess Astra.
