What does Seamus say to Ron after Ginny comes into The Room of Requirement?

I saw a sneek preview of HP7 part 2 while watching Harry Potter and the Chamber of Secrets on July 8th. Harry, Ron, and Hermoine return to Hogwarts, and while they are discussing Rowena Ravenclaw's Lost Diadem Ginny comes in. Ron says how she hasnt seen him in 6th months and that she is his brother. Then Seamus said something to him about Harry that I couldnt understand. Does anyone know what he said. Plz HELP!!
