Harry sat in the Great Hall with Hermione and Ron, eating the Halloween dinner. Hearing a noise below him, Harry passed a spare empty goblet down to the floor, to feel Alucard's hand take it and vanish back into the floor. After several minutes, the doors flew open, and Quirrel ran in, screaming that there was a troll in the school.
As the students began to panic, Dumbledore called for order.
"Students will return to the dorms, and teachers will follow me to the dungeons."
A deep voice suddenly filled the room. "Or you could all just resume eating and allow me to deal with this."
The entire school started as Alucard rose out of the floor beside Harry's chair, drinking blood out of the goblet Harry had given him. Everyone else was horrified, but Harry was smiling. Dumbledore narrowed his eyes.
"You intend to take care of the troll?"
Alucard smiled. "I'll make short work of it. No one interrupts my master's dinner on my watch."
Harry chuckled, as did Hermione, but Ron seemed slightly scared still. Dumbledore nodded.
"Very well. The rest of you may resume eating, but Alucard and I will go to the dungeons."
Alucard's smirk widened. "Oh, you'd never keep up."
Alucard vanished into the floor, reaching the troll in an instant. He raised the massive black gun he had constructed after the destruction of the Jackal, the gun built in Jackal's image, minus the explosive device. Thirty nine centimetres long, weighing sixteen kilograms, firing blessed mercury tipped rounds. The gun he had named Alexander after his beloved deceased nemesis, Father Alexander Anderson. With several shots from Alexander, the troll had been completely destroyed, the explosive shots having reduced it to a pile of shredded flesh.
Up in the Great Hall, Harry smiled as he heard the gunshots, and Dumbledore sat down, all of them regarding Alucard as he reappeared, still holding his goblet. Only Filch seemed openly unhappy, as he would have to clean whatever mess Alucard had made in the dungeon. Snape stood off to the side, concerned. He knew the troll hadn't gotten in by accident. Not far from where Snape stood, Quirrell fought to keep his anger down. His plan had failed miserably. All because of Alucard. Quirrell was furious, and he swore he heard the face under his turban gnash its teeth in rage.
