Studying the Ravenclaw during lunch and later in the library, the trio noticed that she seemed somewhat isolated and withdrawn. Her "relationship" with Blaise and Harry had given her a social boost. Now the other students apparently felt like she had lost that protection, making her a convenient target once again. Well, Blaise was one problem, Luna another. Harry believed in his ability to multitask, especially with Ron and Hermione by his side. So, when someone hexed Luna during dinner, the sixth-year pulled up a shield that reflected the curse back to its caster. He smiled coldly at the Ravenclaw, not saying a word. When Luna had chosen a seat, he gestured for Ron and Hermione to keep theirs while switching tables. "Do you want to tell me why our boyfriend is behaving like an ass?"
