Dr. Martin Ellingham is called to Louisa's new home after she has a dizzy spell while shifting furniture. Martin urges her to slow down, but is shocked to learn that Louisa has applied to be her school's headteacher again, with the previous one getting porphyria and having to leave. Martin refuses an application to an elderly couple for a disabled parking badge when the man who uses a wheelchair refuses to prove he is indeed disabled, thus when Martin tries to gain proof anyway, he ends up stabbing the man in his hand with a surgical pin.
