What does Hannah abbott do in Harry Potter?

She appears through out the series and is one of the only students to believe him when Harry Potter claimed that Voldemort had returned, after he returned to Hogwarts with Cedric Diggory's dead body. She also joined Dumbledore's Army and helped Harry upon discovering that Umbridge had uncovered the location of the D.A. She was pulled out of Hogwarts during her sixth year after being informed that her mother had been killed, presumably by Death Eaters. She returned to Hogwarts for her seventh year and continued to stay loyal to the D.A. where she joined the revised version of the D.A. run by Neville Longbottom, Luna Lovegood and Ginny Weasley. She remained and fought in the Battle of Hogwarts and survived. She eventually married Neville Longbottom.
