Chris Carter and 1013 Productions own the X-Files. JK Rowling, Warner Brothers and Scholastic own Harry Potter. All I own is this story line, every Harry Potter DVD and a complete collection of X-Files DVD's. I wish I owned Fox Mulder.
A/N This story is set anytime during Sorcerers Stone through Prisoner of Azkaban of HP (although it contains information in all the books) and after X-Files episode "Emily", but before "Requiem".
A CORRIDOR
HOGWARTS
A couple days went by without any further incidents, but nobody let their guard down. No one was allowed outside after sunset, and faculty were assigned to patrol the buildings at regular intervals. Snape offered to take Scully with him when he made his rounds--it would give her more opportunity to learn the layout of Hogwarts. Scully was appreciative for the opportunity because it seemed to her that no matter how much time she spent in the castle, there were still new surprises. She could find her way between guest rooms to Great Hall to the Potions classroom and back to the library, but she was continually startled to find a door here she hadn't been aware of or a corridor there she hadn't noticed.
They patrolled late one night along a corridor between dormitories. It was rather chilly, and a large leaded glass window with a view of the Forbidden Forest contributed to the sense of cold. The full moon looked enormous, and illuminated most of the hallway. She drew closer to the window to look out and Snape followed behind. She looked up at the moon, and placed her hand lightly on the glass. "It's so beautiful," she said simply. Snape stepped beside her and took her hands in his, turning her to face him. They looked at each other silently for a moment, then he leaned towards her, pushing back a strand of her hair as he did so.
A door slammed open at the end of the corridor, and they stepped away from each other. Scully turned to see Mulder and Professor McGonagall approaching them.
Professor McGonagall said, "There's been another attack. We are to report to the Headmaster's office". They turned to go and were almost to the door when a loud rumbling was heard from the part of the corridor where Scully and Snape had been standing.
Snape pulled out his wand, turning towards the noise and said, "You three, go to Dumbledore's office--I'll catch up. Go!"
"Not by yourself, Professor. Dumbledore says it's not safe to be roaming by yourself," said McGonagall.
"I'm not one of the students," he replied irritably.
"Scully and I can find our way to the Headmaster's office by ourselves," Mulder said. "It's not that far."
Professor McGonagall looked dubious, but before she could argue, Mulder put his hand on Scully's shoulder. "Let's go, Scully."
"We're leaving the scene?" she murmured incredulously.
"We're going for backup, then you can examine the victim."
Scully turned and followed Mulder as he trotted down the hallway. Suddenly, there was a tremendous cracking sound coming from the ceiling above them and they jumped back as a large chunk of ceiling crashed to the floor. Before the dust had time to settle, there came the sounds of spells being cast by the professors, and the magazines of two guns being slammed into place by the agents. Neither Mulder nor Scully had seen anything unusual up at the ceiling and they watched as Snape and McGonagall used their wands to direct incantations. Although they had their guns aimed, they doubted how much use they would be against whatever was up there.
Eventually, Snape and McGonagall lowered their wands, Mulder and Scully holstered their weapons and the four of them stood looking at each other.
"I don't think that was exactly 'Welcome to Hogwarts'," said Mulder.
"You're saying that was directed at us, Mulder?" Asked Scully.
McGonagall looked uncomfortable. "Just remember, we don't know for sure what that was. But if it were the activity of You Know Who, well, it would be keeping in character for him to attack muggles."
"Is it gone now?" Scully asked.
"If by 'gone' you mean driven off temporarily, it seems that way," muttered Snape.
Mulder walked around the chunk of ceiling, looking at it carefully. Then he hunkered down, pulled out a small plastic bag from his pocket and using a key, scraped some material from the ceiling into it and closed it. McGonagall watched him curiously and Snape, who had been watching the ceiling with an air of expectation, also turned to see.
"We have to report this to Dumbledore--this development," said Professor McGonagall.
"All due respect, I'd like to have a look around here, first," said Mulder.
"Go, Professor McGonagall," said Snape. "Take Agent Scully to Dumbledore's office. We'll be along shortly." He was looking at Scully, who met his eyes before she turned and left with McGonagall.
