I thought Dobby's death was the most touching, the funeral was so sad.
And Fred, Lupin and Tonks was also really sad even more so because of baby Teddy. I'm assuming he was brought up by his grandmother but spent a lot of time with the Potter and Weasley families.
I have to say that I thought Neville seemed like a totally different person when he first entered the scene in this book. It just didn't sound like him at all but yay for him killing the snake.
Not sure what to think of Snape. I've sort of hated him from the start and always thought that he would be evil, however I'm sort of coming round to him. I was dreading him turning out good because I didn't know how JK Rowling could have justified him being evil throughout the past 7 years, and then suddenly turning good at the end, but I think the way in which his actions were explained was done really well. Just the fact that he'd been in love with Lily for all these years hence his hatred for James and Harry, but at the same time doing his best to protect Lily's son. I thought that was a nice little twist and the fact that his patronus was the same as Lily's - aww cute!
Mrs Weasly was amazing.
I liked the epilogue at the end and thought it was a nice touch finding out what happened to the three main characters, but at the same time a little disappointing. I mean what about all the others? We don't know what happend to George after Fred died. We don't know what any of them are doing for a living except Neville. And what happened in the wizardring world after the downfall of Voldermort? How long did it take them to get back to normal and what happened at the ministry?
