Book 6 | Ch:17 - A Sluggish Memory

SPOILERS:

Back at Hogwarts, Harry chats with Hermione about Ron and Malfoy, learns that apparition lessons are coming, and finds that both Ron and Ginny seem disenchanted with their relationships. He then has a lesson with Dumbledore, where they discuss Scrimgeour and see two memories: in the first, Morfin tells Voldemort about his family just before Voldemort kills the Riddles; in the second (which Slughorn has modified), Voldemort asks Slughorn about horcruxes. Finally, Dumbledore sets Harry homework – to obtain the rest of Slughorn’s memory.
