This week we have a puzzle, written by Caius Marcius, one of our Great Brains.  Should be a fun one:
  
The following is a partial list of the last spoken line of dialogue by JKR's characters in the canon so far. Identify the speaker, and for extra credit, the book and the chapter.  Most of these can be found toward the end of GoF - most, but not all....... 

"Just you and me, Harry Potter ... you and me...."  

"Take my body back to my parents…." "He'll lend you one." "See you, Harry" 

"He is mine!" "Thanks for the socks, Harry Potter!" 

"….tell him what Peeves was up to…." 

"You're going to have to fight the Cruciatus Curse!" 

"We will return, if you please, to history, to solid, believable, verifiable fact!" "They're supposed to be really hard to catch!" 

"There should have been a presentation ceremony, but under the circumstances…." –"I am." "Severus Snape is a Death Eater!"

"Keep in touch, Harry" "Harry,""Well, second – Diggory was the f-"  

"Remember Cedric Diggory" 

"Cedric Diggory" 

"Bye, Harry" 

"Very – very well," 

"He can still be gamekeeper, can't he?" 

"But I must do what I can, you do understand, don't you?" 

"Goodbye, then." 

"Leave it to me," 

"No," 

"..not that it needs it..." 

"Headmaster, there is no need to see me to the gate, I can manage…." 

"You fight him, boy…" No my Lord….never, my Lord" 

"Buy Ron some different robes and say they're from you."  

"….I don't like them much, they always chase me when I get too close…." 

"AARGH!" 

"These deaths were not the random work of a lunatic!" 

"I was jokin' – jokin'!" 

"I'd better hurry – you have a good term, boys!" 

"Take them away, and may they rot there!" 

"Three – two – one" 

"If you leave now, you may lose the opportunity to see further than you have ever-"

"I still can't work out how you two got the best-looking girls this year." 

"He is returned to power and I will be honored by him beyond the dreams of wizards."

"I'm about to become the youngest ever Minister of Magic, I am." 

"...how you managed to return to us...."
