Harry didn't know what Ginny was going to do. He never did. In fact that was part of the appeal, someone to keep him on his toes.

Growing up in a cupboard under the stairs, then finding out you're some supposedly fabled person, then running around for seven years chasing someone and their goons. I'm not sure what I'm to be doing. I figure at least if I can be an Auror chasing after people is something I've shown I already excel at, right?"
