Harry is at a Loss
Sitting in the [hospital wing], Harry, Hermione, Ron, Ginny, Neville, and Luna discuss Voldemort's return and the [Daily Prophet]'s ceasing its mistreatment of Harry and [Dumbledore]. As the conversation turns to the [prophecy], though, Harry gets uncomfortable and departs.
Harry wanders aimlessly, unable to decide whether he wants to be with his friends or alone, when he encounters an angry Malfoy. Just before they can duel, however, Snape interrupts, but his attempt to take points from [Gryffindor] is thwarted when McGonagall interrupts him as well, adding points instead.
