Disclaimer: I've lost myself! I have no idea where I am on my hunt for Eros. So I just caught a flight home. I missed my kids anyway. Lestrade still isn't mine and neither is anyone else and I make no money off of my stories just laughs.

A/N: So did anyone catch who they're supposed to be looking for? If not…well, I'm not telling. So this chapter begins the next crossover in our story. I'm not telling what movie it is because if you know the movie then you know this character and if you don't know the movie then…telling you would be rather pointless because it will still make no sense. If you review and ask for the name of the movie I'll tell you. Everyone confused now? You are? Good.

Also I apologize for not updating yesterday but it was graduation and so I was a bit busy.

At Hogwarts

Chapter Two: The Castle

Sherlock and John were silent as they followed the three magical people through the castle. Everywhere they looked there was evidence of magic and wonder. Portraits moved and spoke. The staircase seemed to have minds of their own. Sherlock thought he even saw one of the suits of armor wave at him. Not really believing himself he waved back.

"Did that armor just move?" John whispered to him.

"I think so," Sherlock whispered back.

Finally they came to what looked like a dead end with only a stone gargoyle and a door with no handle. "Good afternoon, Crispin," Harry said to the gargoyle.

"Afternoon, Mr. Potter," the gargoyle grinned at them. "And friends. Oh! And the lovely Luna! How are you, Mrs. Potter?"

"I am well, Crispin, thank you," Luna said. "How are you?"

"Stiff," he answered and then laughed at his own joke.

"I still find it hard to believe the two of you made friends with a stone gargoyle," McGonagall shook her head. "Lion's Pride," she told the gargoyle.

The gargoyle pouted at her. "I was havin' a conversation, Minerva. Why'd you have to go and give me the password so soon? No one ever wants to just talk to me! Harry and Luna are the only ones who just want a chat."

"We have things to do today, Crispin," McGonagall said through clenched teeth. "We have already wasted enough time."

"I don't think it's a waste of time to talk to me," the gargoyle grumbled even as he slid to the side and the door opened.

Luna patted his head as she followed McGonagall through the door. "I don't either, Crispin. You know everything about this castle, don't you?"

Crispin leaned into her touch. "The castle speaks to me, she does. Tells me what I need to know about the students and teachers and everyone within her walls."

Luna nodded and glided through the doorway. Harry paused. "Crispin, this is Sherlock and John. They're my friends."

The gargoyle looked over at them and grinned. "Any friend of Harry's or Luna's is a friend of mine. Welcome to Hogwarts, Sherlock and John."

"Hey, Crispin, do you know what has McGonagall in such a lather?" Harry asked.

The gargoyle chuckled. "I do as a matter of fact. Some Muggle man, boy really, showed up this morning and found his way into the castle. He was poking around and McGonagall caught him. He claims he's here looking for the Philosopher's Stone."

"But the stone was destroyed years ago," Harry protested. "Or at least that's what Dumbledore told me."

"If he did destroy it he didn't do it within these walls," Crispin muttered. "Delusional old fart he was. That Muggle boy, he told McGonagall that his 'instruments indicated that the Philosopher's Stone is inside this castle'. She huffed at him and dragged him off to her office."

"Guess we'd better go find out what's going on then," Harry said and patted Crispin's head as he moved by him.

John followed his lead. "It was nice to meet you, Crispin." He said and thrust his hand out to shake the gargoyle's stone appendage.

"And you, Dr. Watson," Crispin's gravelly voice was suffused with pleasure and he creaked a bit as he grasped John's hand and shook it.

Sherlock bent so that he was eye level with Crispin. "You are completely sentient then?" He asked. "Fascinating. I look forward to conversing with you at a later date, sir."

Crispin's face creased in a delighted grin. He was unused to such attention, magical people took him for granted for the most part. "I shall await that day, Mr. Holmes, with much anticipation." They shook and Sherlock followed the others into the small room.

Ahead of him and up he saw McGonagall riding a moving spiral staircase upwards to another door. Luna was waiting at the bottom and held her hand out to Harry to join her. Harry did so and the two stepped onto the staircase as it began to carry them up. "An escalator in a castle?" John's smile was amused.

McGonagall gazed down at them as they boarded the staircase with a bemused look. "Whatever is an es-ca-lay-tor, Dr. Watson?" She asked.

John craned his neck upwards to look at her. "This is an escalator, Professor McGonagall. A moving staircase, though ours are powered by electricity and I would bet this one is powered by magic."

McGonagall sniffed and looked forward again. "This staircase has moved in this way for hundreds of years." She said.

John shrugged. "It's still an escalator and not all that different from the ones in our world, though as far as I know none of ours are spiral."

"They're not," Sherlock confirmed. "However, with the advances in technology it's only a matter of time."

McGonagall looked down upon them again as she stepped off the staircase in front of another door. "Do you really believe that your tech-tech-know-low-gy is able to mimic our magic?"

Sherlock gave her a glare from beneath dark brows. "In some ways I know our technology surpasses your magic," he bit out.

"Mr. Holmes," McGonagall began in a patronizing tone.

"He's right," Harry interrupted her as he and Luna came to a stop beside her. "A wizard cannot instantly speak with someone in China, for instance. Muggles can. A pureblood witch or wizard would never even think of travelling to space and yet Muggles have been doing so for half a century."

McGonagall's eyes rounded. "We will speak more of this later," she stalled. "For now, you need to straighten the Muggle in my office out and get him to leave Hogwarts." She opened the door as John and Sherlock stepped off the staircase and stood behind Harry and Luna.

McGonagall opened the door to her office and glared at the crash from the inside. "Sorry, sorry," a voice called out. "Severus told me to."

"And how old are you, Mr. Carson?" A smooth baritone answered the accusation. "Are you incapable of using common sense?"

"That artifact was a priceless ancient treasure from Babylonia," an elderly man's voice said in tones of extreme disappointment.

"Please," the first voice said. "It said 'Made in Japan' on the bottom and I know it's a child's toy."

McGonagall pushed the door all the way open and glared into the room before her. "Mr. Carson, I do not care where it was made or what it was," she started.

"Oh, hello, Professor McGonagall," the first voice, obviously this Mr. Carson, said. "Did you find the person you went to look for? I must admit that I'm very anxious to meet Mr. Potter. If he's done all you say then he must be a very powerful magician."

"I'm a wizard actually," Harry informed him as he pulled Luna into the room. John and Sherlock followed hot on their heels. "Good afternoon, everyone."
