Every few years we must meet heartbreak and anxiety with enthusiasm as we anticipate a new Doctor. That time has come again as we bid farewell to 11 and welcome 12. Matt Smith ended his 3 season reign as the 11th Doctor last year in The Time of the Doctor, the 800th episode of BBC’s long running series. The Doctor, who had run out of regenerations, was gifted more regeneration power by the Time Lords. Using the energy of his regeneration, The Doctor destroyed the Daleks, and said a final goodbye to Amy Pond (in the form of a hallucination), before regenerating into his 12th incarnation.
