Dolores Umbridge succeeds to Dumbledore as headmistress after his flight. Harry hears that Umbridge immediately wanted to move into Dumbledore′s office, however the gargoyle sealed it without letting anybody in. Fred and George tell the others, that they have put the Slytherin Quidditch-Captain Montague headfirst into a Vanishing Cabinet. Furthermore they decide to cause trouble and chaos in school in order to make life as difficult as possible for Umbridge who tries to use Veritaserum to question Harry about Prof. Dumbledore’s residence and about Sirius Black. As Harry only pretends to drink, the witch doesn′t find out anything. The following evening, he meets Cho on his way to Prof. Snape′s Occlumency lesson. They talk in a sharp tone about Marietta. The conversation escalates, so Harry leaves for his lesson full of anger. Through a coincidence Prof. Snape and Harry get interrupted by Draco Malfoy, member of the new Inquisitorial Squad, shortly after the beginning of the class, as Montague has been found in a toilet and Prof. Snape′s presence is indispensable. As Snape and Malfoy leave the room, Harry recognises the Pensieve, in which the teacher hides secret memories before every lesson. The boy lets himself drop into the memory which shows Snape during his own OWL examination, when he is about 15 years old. Harry notices amazed that the Marauders sit in the same hall. Harry follows the friends to the lake where James and Sirus start to jinx and abase Snape, because they are bored. Lily Evans tries to stop the Marauders, but Snape insults her acrimoniously, probably because of shame. James asks Lily about a date, which she denies sharply and leaves. Harry gets torn out of the memory and recognises the adult Prof. Snape next to him, who is very angry about Harry′s behaviour. Beside himself with rage and shame he chases the boy out of his office and forbids him to come again. Harry is deeply saddened about the fact that his father was actually as arrogant and big-headed as Prof. Snape always alleged.
