The D.A. Practices Patronuses in the Room of Requirement

PAGES: 606-607

The D.A. members practice conjuring Patronuses under Harry Potter's guidance. Many struggle to produce fully formed Patronuses, including Neville Longbottom and Seamus Finnigan, but some, like Cho Chang and Hermione Granger, succeed. The lesson is interrupted when Dobby the house-elf enters in a panic to warn Harry that Dolores Umbridge knows about the D.A. and is coming to catch them.
