I always liked the adult covers of the Harry Potter books that you can get in the UK. I wish we could get them here. (sigh)

The King's Cross scene was a bit weird in many ways. Like Harry I was wondering how much of it was real and how much of it was Harry's way of dealing with what was happening to him at that moment.

If it is the later, then Harry probably would not know initially that the crying thing was Voldemort. When Dumbledore tries to divert Harry's attention from it, it is more Harry's way of trying to force himself to focus on that which he could understand and less on what he could not.

If it really is Dumbledore then I am guessing that Dumbledore was trying to get Harry to focus on what Harry could control and what was more important. There was nothing that Harry could do to help Voldemort so why spend time on it?

Dumbledore has always been portrayed as being practicle in these matters. Why else would he allow Harry to face Voldemort back in book 1? Harry needed to learn what he was capable of and begin to develop the skills that would be needed when he finally confronted Voldemort. Harry himself commented that Dumbledore knew pretty much everything that was happening at Hogwart's, so Dumbledore could have stopped Harry in any of the books but he never did. Harry had to learn how to survive with as little help as possible. That is not to say Dumbledore did not help Harry, he did, but always in the form of out of context comments and gifts. So that practicality carried over to Dumbledore in limbo.
