In the fifth episode with Twelve, we finally get a glimpse of the man we know the Doctor to be–the man who risks it all to help others. While last week’s episode explored the mytharc of the Doctor in an abstract and thoughtful way, in “Time Heist” we see Twelve chose a familiar path, and, although he has been acting very different than Eleven, we are reminded that the Doctor made a personal commitment to help the universe, and he will continue to see that oath through, regardless of the cost.
