The Second Doctor was a shock to the system. Gone was the cranky but benevolent grandfather to be replaced by what at first seemed to be a devil-may-care clown. His trademark tin whistle and hobo clothes disguised a wit and intellect, though. And that was his best weapon against his enemies. Almost always they mistook him for a fool who could be discounted in their plans and he outwitted them with clever trickery and sound scientific knowledge. His friends found him a gentle, kind man. His enemies often felt the steel beneath. He could appear to be a coward – when outnumbered his reaction was to run. But that was simply his way of exercising the better part of valour. His courage could not be doubted by those who truly knew him. He had emotional vulnerabilities that showed through from time to time. When he told Victoria that his family slept in his mind, we saw a flash of his hidden tragedy. For the first time, we learnt that The Doctor was a Time Lord, one of a race of powerful people, but with very little tolerance for dissent, and when they caught up with him he had to fight for his life.
