humans cannot, Nagini is able to detect Harry and Hermione even when they are under the Cloak of Invisibility. After discovering that Harry is searching for his Horcruxes, Voldemort places Nagini into a protective magical cage to prevent her from being killed, but uses her to kill Severus Snape by expanding the cage over him. When Harry is apparently killed by Voldemort, Nagini is released from the protective enchantment and is draped around Voldemort's shoulders during the Death Eaters' victory march back to Hogwarts.

Filch, who is usually left with cleaning up the mess and damage that Peeves causes, tries repeatedly to remove him; however, Rowling has stated in an interview that not even Dumbledore would be able to rid Hogwarts of Peeves forever. Peeves is vulnerable to some magic; in Prisoner of Azkaban, Professor
