I know! I loved when McGonagall said, "It's high time your grandmother be proud of the grandson she has rather then the one she wishes she had."
I was also very surprised that we didn't hear anything about Susan Bones. With Ameila Bones' murder she's basically an orphan. Voldermort killed her entire family. I think we will hear more from her, too.
I think you are right with Neville. Ever since the last book, I thought there were bigger plans for him. I thought Amelia Bones may have taken the locket and she goes by Amelia when it was actually her middle name. That would at least cover the last 2 initials. It may be Regulus Black, which would explain mention of a locket that no one could open. Although, they did say that Voldemort actually killed Amelia Bones himself.
I think DD is really dead, and Fawkes will somehow go to Harry. I was sure he died when Harry could move. It sure is fun to speculate on things though! After awhile though, I need to get out the tinfoil! LOL!
Susan Bones was mentioned in the chapter on Apparitions.
I think Amelia Bones was her AUNT, not her mother.
And this is why I keep feeling that a Bones relative (perhaps even Amelia herself) is "RAB."
