Ron's stern older brother, Percy Weasley (Chris Rankin), is barely featured in the second film. However, in the book, his role is slightly more significant. He has a secret relationship with a Ravenclaw student named Penelope Clearwater. After Ginny is saved from the Chamber of Secrets, she reveals that she caught Percy and Penelope making out. This delights her brothers, Fred (James Phelps) and George (Oliver Phelps), who look for any opportunity to make fun of their uptight sibling.
The Basilisk also petrifies Penelope Clearwater and Hermione at the same time. The mirror that Hermione is seen holding in the movie actually belongs to the Ravenclaw Prefect. Penelope's petrification understandably upsets Percy, giving him some emotional depth, which he is typically lacking.
Penelope is not even mentioned in the movie. Instead, the Basilisk only has five victims — Hermione, Nearly Headless Nick, Mrs. Norris, Justin Finch-Fletchley (Edward Randell), and Colin Creevey (Hugh Mitchell).
