Here's the other of the Patil sisters, played by Shefali Chowdhury. If you've always believed that the Patils were sisters in real life, we're sorry to shatter the illusion for you. They may look alike, but they have no family in common at all. Parvati's main role in the Harry Potter story was to get irritated with him when he ignored her at the Yule Ball.
Her three appearances in Harry Potter were pretty much it in terms of Chowdhury's acting career, although she has been back in front of the camera for a couple of low budget short films in more recent years. Stepping away from fame, she was known at one point to be studying photography back home in Birmingham, England, and her social media accounts indicate a strong interest in environmental concerns and animal rights issues.
