Lupin's secret after completing Snape's homework assignment from the class. Crookshanks proves vital in exposing Scabbers as Peter Pettigrew, an erstwhile friend of James and Lily Potter, who revealed their whereabouts to Voldemort the night of their murders, and was able to wrongly implicate Sirius Black (revealed to be Harry's godfather) in the Potters' deaths. The Time-Turner enables Hermione and Harry to rescue Sirius and the hippogriff Buckbeak. Harry Potter and the Goblet of Fire Hermione is horrified by the cruelty that house-elves suffer, and establishes S.P.E.W., the Society for the Promotion of Elfish Welfare, as an effort to gain basic rights for them. She is Bulgarian Quidditch prodigy Viktor Krum's date at the Yule Ball of the Triwizard Tournament.

Harry Potter and the Order of the Phoenix Hermione becomes a Gryffindor prefect along with Ron and befriends Luna Lovegood, but their friendship has a rocky start after Hermione chastises the publication of Luna's father: "The Quibbler's rubbish, everyone knows that." She also lambasts housemate Lavender Brown for believing the Daily Prophet's allegations of Harry fabricating stories of Voldemort's return. Ron and Hermione spend much of their time bickering, likely due to their growing romantic feelings toward one another, but they show continued loyalty to Harry. One turning point in the series is when Hermione conceives the idea of Harry secretly teaching defensive magic to a small band of students in defiance of the Ministry of Magic's dictum to teach only the subject's basic
