931. Millicent Bulstrode and Ernie Macmillan became best friends in fifth year after Ernie stopped some younger students making fun of Millicent for her size. They kept their friendship secret so that Millicent could help pass information on the Inquisitorial Squad to the DA; she was the one who tipped off Dobby about the raid on the Room of Requirement. They remained best friends for life.
