For a moment, Hermione was held fast, not sure where to go. There were screams and shouts, bangs and blasts, as spells criss-crossed in each and every colour and in every direction. Then Hermione chose her target. Oliver Wood was hit by a spell and doubled up, and Patrick O'Brien darted forwards into the breach, but he was smashed aside too, by the force of the spell which quickly hit him. Hermione looked ahead and saw the reason ... both were trying to fight Dumbledore ... and that was simply the wrong opponent for them.
