Scarlett Byrne as Pansy Parkinson – Then
Pansy Parkinson was a student at Hogwarts School of Witchcraft and Wizardry, sorted into Slytherin House, where she later became a prefect in her fifth year. During the Second Wizarding War outbreak, Pansy expressed her desire to hand over Harry Potter to Lord Voldemort to save the rest of the students.
Professor McGonagall decided to send Slytherin to the dungeons at the onset of the war, so it was assumed that they remained there and survived.
