I think what I got of that interview is that she said that it is going to be odd or it was odd to see Harry and Ginny together since she picture herself when reading the books, she also wasn't sure about what will happen to her in future movies (if she will be back or not) and if I am not mistaken (bcos I listen this interview just once) I think Stuart Craig (Production designer) confirmed that the trio are going to be back for OotP (that was at the end of his interview)
