Malfoy: he is showing the strain. And we know Harry is wrong that the mission is going badly. The paleness and thinness are therefore signs that he is not happy about the mission progressing as planned. The swagger and self-assurance is gone, not because he is failing, but probably because the horror of what he has to do is getting to him. This is confirmed, of course, in the bathroom scene.

Ron and Hermione: their being in the boys' dormitories apparently alone must look suspicious to Lavender. While I am glad the whole absurde relationship is over, Hermione is right that Ron is a bit of a coward. Still, it is nice to see her cheery. And she so knows that Harry has a crush on Ginny. Hermione knows. And I like their reactions when Harry and Ginny finally get to it.

Slughorn: he is such a delightful mix of the good and the bad. I like him. He is horrible in his calculating and downright greedy approach to Hagrid's grief. And his reference to having had house elves taste all the bottles in case they were poisoned is horrible. And the casual nature of it makes it worse. He is apparently not aware that it is wrong. But then he does give Harry the memory. Pressed and drunk, yes. But I am not sure that is to be held against him here. I like how he in contradictory. There is too much good vs evil in fantasy writing. His reason for keeping it secret is also interesting. Guilt or shame clearly plays a part. But it would also seem that he is reluctant to help kill Voldemort. Probably because he remembers Tom as a good student who treated him well. And his horror at the thought of Horcruxes show that while he is perhaps not a thoroughly decent fellow, he has a moral compass.

Voldemort: He really does not treat his soul very nicely. Not only is he ripping it apart in all sorts of ways, he casually uses one part as a weapon. Of course, that is an indication how important the part of his identity as the heir of Slytherin was to him, but still...

Snape: Using that type of deep legilimency (not just a surface skim to see if someone is lying or not) on a student without permission seems like a violation which should not be permitted. Still, the situation is quite singular. And he is surprisingly lenient when it comes to punishment, considering.

Ginny: why is her face described as hard when she is approaching Harry to embrace him?
