Interesting. You know, I'd like to think this is the solution of the puzzle of why Harry seems so indifferent at the beginning of the HBP. But I guess I've always taken it for granted that Harry really is kind of obsessively infatuated with Sirius, even if I think it's unhealthy and wrongheded. I think he should have gotten over Sirius, but given what we see of his emotional life, I'm not sure I can plausibly see how he could have done so in that short time. Do you see evidence that Harry, himself, has any insight into all these bad things about Sirius that the reader picks up on?
