Member= Katie Bell

Katie Bell joins the Gryffindor Quidditch team in her second year (Harry's first) as a Chaser, and joined the D.A. in her sixth year. In Half-Blood Prince, she is the only remaining member of the original Gryffindor team that was helmed by Oliver Wood, and she advises Harry not to discriminate in favour of old players like her, but to hold trials for all. She nonetheless succeeds in retaining her spot as Chaser alongside newcomers Ginny Weasley and Demelza Robins.
In Half-Blood Prince, Malfoy secretly attempts to use Katie to deliver a fatally-cursed necklace to Dumbledore. Madam Rosmerta, whom he has placed under the Imperius Curse, gives it to Katie in Hogsmeade, but Katie accidentally touches the necklace through the torn package and is badly cursed. Fortunately, she only touches it with a minute amount of skin due to a small hole in her glove, but she is nonetheless hospitalised for several months in St Mungo's, and is temporarily replaced by Dean Thomas on the Gryffindor team. Katie returns fully healed to participate in Gryffindor's Quidditch Cup final win over Ravenclaw. In Deathly Hallows, she reunites with Oliver, Alicia and Angelina to assist the D.A. in the Battle of Hogwarts.
Katie was portrayed by Emily Dale in a non-speaking part in the first two films. She featured in an expanded role in Half-Blood Prince and was played by Georgina Leonidas, who also voiced the character in the video game adaptation
