I'd like to point out that Hermione stopped smiling 1 year before Harry and Ron did. She probably knew the danger long before them <--- I'd like to point out that Harry stopped smiling after year two and Hermoine smiled year three.
Book VII from Fred and George sucks. I sorta expected Dumbledore to Obi-Wan on us (that's the way Heroic quests flow), but Sirius and Dobby, I thought it couldn't get worse. Fred was the worst. - Harry Potter / Fred 'n George Weasley.
