Klempari defence

The Klempari defence was a term which referred to the claim that an individual was the last of their kind. Alaya tried to use it as she was being questioned by the Eleventh Doctor, but as he was the last of the his own kind, he was quickly able to deduce that she was lying. He also mentioned that it was "a bit old-hat" when it came to interrogation defences. (TV: The Hungry Earth)
