Quirrell raised his hand to perform a deadly curse, but Harry, by instinct, reached up and grabbed Quirrell's face. Amelia jumped on his back clawing at his neck.

"AAAARGH!"

Quirrell rolled off him, his face blistering, too, and then Harry knew: Quirrell couldn't touch his bare skin, not without suffering terrible pain -- his only chance was to keep hold of Quirrell, keep him in enough pain to stop him from doing a curse.

Amelia's head was burning with pain, but she wouldn't let go, she had to hold on. 

Harry jumped to his feet, caught Quirrell by the arm, and hung on as tight as he could. Quirrell screamed and tried to throw Harry off -- the pain in Harry's head was building -- he couldn't see -- he could only hear Quirrell's terrible shrieks and Voldemort's yells of, "KILL THEM! KILL THEM!" and other voices, maybe in Harry's own head, crying, "Harry! Harry!"

Amelia fell to the ground.. 

He felt Quirrell's arm wrenched from his grasp, knew all was lost, and fell into blackness, down ... down... down...

Something gold was glinting just above him. The Snitch! He tried to catch it, but his arms were too heavy.

He blinked. It wasn't the Snitch at all. It was a pair of glasses. How strange.

He blinked again. The smiling face of Albus Dumbledore swam into view above him.
