De-lurking to throw in my two knuts...
While I laughed at Molly's outburst and subsequent fight with Bellatrix, I think I laughed more when Dumbledore revealed that Snape had to kill him and Snape's response was "What? Now? or should I give you time to write your epitaph?" Or something to that effect. (Maybe I was just exhausted.)
Chapters I definitely have to re-read for clarity:
Chapter 13 - the Ministry mission
Bathlida's secret (I went cross eyed trying to read it and keep the facts straight)
And the last couple o' chapters. Especially Harry's monologue and whole "who's the Elder Wand's true owner," etc.
I thought the epilogue was all Velveeta cheese... but I was left with similar questions as pp have mentioned. (Jobs, did they finish, who's in charge, etc.) Did anyone get ages from the children? (Lily was underage, James was older, Albus is 11... didn't catch the other 2 children.) Maybe she did this to put all of the crazy H/Hr and R/Hr and H/G shippers at ease.
Wasn't their something about Lily's hand at charms being really important... wasn't that a clue before this book came out? Or was that plot point nixed?
And how the HELL are they going to make this a movie? The small plot points were important. Especially, how are they going to bring back Dobby after not seeing him since the 2nd movie? Spoiler:
(Only to kill him again.)
Maybe I'm the only one that thought Deathly Hollows was a location...
A small part of me would have gotten a kick out of Krecher with the fake locket saying "My Precious..." but that's just me. LOL.
