Y/N is the only foreign member of the Harry Potter cast. She was casted as Astoria Greengrass, a pure blood Slytherin witch which would be later on in a relationship with Draco. The cast is wonderful and caring but Tom makes her life way more difficult on set. Difficult not with bullying - he’s the last to bully her. He knows she has a language barrier and so he uses she most British slang one could think of, and he does it with a smile, trying to teach her the practical language.
