Heh, so I definitely just fell into an alternity-hole as I went and combed through the text for evidence of Dolohov's feelings on death. His talk with Seamus after the rite where he talks about owning what you've done and honoring the life you snuffed out and then his talk with Pansy about the memorial garden are all pretty interesting.
And of course, as kiya noted below, the story of Clarkson was quite chilling and corroborated by Sally-Anne describing his impassive professionalism when cutting her down. Poor Perks, she's going to give herself away by being tense tomorrow.
ETA: And re-reading that made me wonder about the little girl that was in the house with Clarkson! I guess we don't have a precise age on her so she may have already made it through Hogwarts by now.

In other news, looks like LM is OK for now, at least. Perhaps everyone currently standing will make it out unscathed this year?
However, it does look like the private message readers are still reading and Ron's conversation with Arista will probably get noticed, then, won't it? Unless it's Percy doing the reading, maybe?
