No! No! NO!

Hermione Granger:

[the Trio walks through the courtyard]
Where is everybody? [They open the doors to the Great Hall. It is a total wreck, lined with students, teachers, the injured, and the dead. Ron walks in first, followed by Hermione, then Harry, who passes everyone almost as if he is in a daze, unable to comprehend what is going on around him] Professor Horace Slughorn:
[Applying Dittany to a wound on Filch's arm]
Harry... Professor Pomona Sprout:
[Dealing with a student's wound]
Oh come on, what's the matter with you? Padma Patil:
[Sitting next to Professor Trelawny and pulling a sheet over a teacher's body]
Oh, she's passed. Professor Sybil Trelawney:
There, she's gone. Ron Weasley:
[the next sight stops Harry dead in his tracks. The Weasley family are gathered around the body of Fred. Ginny and Percy both stand motionless. Bill holds a crying Fleur. Molly's head is buried on her dead son's shoulder. Arthur is trying to comfort George as best he can. George sees Ron and grabs onto him for dear life, sobbing uncontrollably. Ron kneels over Fred's body and lays his head down on his chest as Molly gently strokes both of their heads]
No! No! NO! [Stunned, Harry glances to his left and sees the body of Remus and Tonks]
