Dumbledore encourages him to continue, after transporting him to see a former professor, Horace Slughorn, hoping that Slughorn would return to Hogwarts and take Harry under his wing.Meanwhile, Death Eaters begin to wreak havoc both towards Muggles, destroying the Millennium Bridge, and Wizards, kidnapping the wandmaker Mr. Ollivander and destroying his Diagon Alley shop.

Meanwhile, Ron becomes the successful Gryffindor's Quidditch goalie, attracting the love of Lavender Brown, much to Hermione's chagrin. Harry is also upset over Ginny's attraction to Dean Thomas. During the Christmas Break while Harry and Ron are at the Burrow, the Death Eaters with Bellatrix in charge come intending to kidnap Harry, but are forced to retreat after they are outnumbered by Order of the Phoenix members. Before they leave they set fire to the Burrow, and the Weasleys...
