Mary Cattermole's Interrogation by Umbridge

Inside the courtroom, Umbridge, along with Corban Yaxley and Hermione (disguised as Mafalda Hopkirk), presides over the interrogation of Mary Cattermole. Umbridge cruelly questions Mary Cattermole, accusing her of stealing a wand and lying about her magical heritage. Hermione notices the Horcrux locket around Umbridge's neck. Harry, still invisible, sneaks up behind Hermione and reveals his presence. He prepares to act as Umbridge continues to lie about the locket's origin.
