Padma Patil

Padma Patil is a Ravenclaw student in Harry's year, and the identical twin sister of Gryffindor student Parvati Patil. While both sisters are sorted in Philosopher's Stone, Padma is not mentioned again in the series until Goblet of Fire. Padma attends the Yule Ball with Ron, at the urging of Parvati (Harry's date) when Harry begs her to find a date for Ron. Padma, however, is less than enthusiastic at having Ron for a partner, since he refuses to dance with her and instead spends the evening stewing in jealousy over Hermione's date with Viktor Krum. Padma and Parvati both eventually abandon their disinterested dates and dance with some Beauxbatons boys. In Order of the Phoenix, Padma becomes a Ravenclaw prefect, and joins the D.A. along with her sister. They are taken home by their parents after Dumbledore's death and subsequent funeral at the conclusion of Half-Blood Prince, but in Deathly Hallows, they return to take part in the Battle of Hogwarts.
Afshan Azad appears as Padma in Goblet of Fire, Order of the Phoenix, and Half-Blood Prince. In the film series, the Patils are Gryffindor housemates and fraternal twins.
