Lupin crossed to the door and closed it behind Harry. 

"No. Professor Dumbledore managed to convince Fudge that I was trying to save your lives." He sighed. "That was the final straw for Severus. I think the loss of the Order of Merlin hit him hard. So he -- er -- accidentally let slip that I am a werewolf this morning at breakfast."

 "You're not leaving just because of that!" said Harry. 

Lupin smiled wryly.

"That's bullshit!" shouted Amelia, her voice changing accents. She turned to Harry, "Take your damn accent back! I've been yelling in it all damn year!"

 "This time tomorrow, the owls will start arriving from parents.... They will not want a werewolf teaching their children, Harry, Amelia. And after last night, I see their point. I could have bitten any of you.... That must never happen again." 

"You're the best Defense Against the Dark Arts- teacher we've ever had!" said Harry. "Don't go!"

 Lupin shook his head and didn't speak. 

"You shouldn't have to quit just becouse they are racists! You forgot your potion one-time since being here, and it was becouse of us!" said Amelia, "You're the best teacher we ever had! The last two guys wanted to kill us!"

Lupin shook his head. "A few centimeters deeper, and I could have killed you," said Lupin," now you will have a scar there,"

"So what?" asked Amelia, "It was my dumbass idea to fight you! You're fucking six feet tall as a human. No shit I got a scratch!"

Lupin carried on emptying his drawers. Then, while Harry was trying to think of a good argument to make him stay, Lupin said, "From what the headmaster told me this morning, you saved a lot of lives last night, Harry. if I'm proud of anything I've done this year, it's how much you've learned.... Tell me about your Patronus."

 "How d'you know about that?" said Harry, distracted. 

"What else could have driven the dementors back?" 

Harry and Amelia told Lupin what had happened. When he'd finished, Lupin was smiling again.

 "Yes, your father was always a stag when he transformed," he said. "You guessed right... that's why we called him Prongs."

"Why not Rudolph or Bambi?" asked Amelia.

 Lupin threw his last few books into his case, closed the desk drawers, and turned to look at Harry. 

"Here -- I brought this from the Shrieking Shack last night," he said,
