Death is the Only Answer

"Death Is the Only Answer" is a special mini-episode of the British science fiction television series Doctor Who that was first broadcast on BBC Three (as part of Doctor Who Confidential) on 1 October 2011. It was written via a "Script to Screen" competition in which junior schools were asked to write a script including the Eleventh Doctor and an enemy of his. The competition was won by the children of Oakley CE Junior School.

In the mini-episode, the Doctor's fez calls its former owner Albert Einstein (Nickolas Grace) into the TARDIS. Einstein carries a mysterious liquid which changes Einstein into an Ood.
