The Inspector

The Inspector was a robot, labelled as the property of the Governors, who was sent to Coal Hill Academy to evaluate Miss Quill under the guise of an Ofsted inspector named Paul Smith. He was destroyed by the skin-peeling dragon, revealing his true nature to Quill. (TV: The Coach with the Dragon Tattoo)

He was later revealed to be expensive and difficult to replace. (TV: Co-Owner of a Lonely Heart)
