I'm in a very PotterLock mood. So I think this is going to be a bunch of one shots for a potterlock AU I'm working on (Not related to the last one I posted. Totally different) I'm going to file this under complete just in case I decide to you... Never update this. It's just short one shots and such, headcanons and other random ideas. I hope you enjoy this nonetheless because I did put alot into this. I should probably make a few things clear first.

BEFORE YOU READ: Sherlock is a Slytherin, and John is a Gryffindor. They are 2 years older than Harry. They're in the same year as Fred and George. John is in their dorm room. Mycroft, when he was at school was a Ravenclaw, he was a 6th year when Sherlock came to school, so he left the year before Harry came. Lestrade was a year younger than Mycroft and was in Hufflepuff. Molly is in Hufflepuff and is two years younger than John and Sherlock so she's in Harry's year. Sally is a Gryffindor in their year while Anderson is a Ravenclaw. Moriarty (Slytherin) and his boys are the same year as Sherlock and John (and by default Sally, Anderson, Mike (Stamford. Didn't mention him yet? Hufflepuff) And Fred and George.)

Not too complicated right? If you're still confused say so in a review and I'll try and straighten you out. And to make things even easier I'll be sure to mention what book it takes place in, and restate their years and houses when they appear in the chapter.

In this chapter:

Chamber of Secrets: Sherlock Holmes (4th year) Slytherin. John Watson (4th year) Gryffindor

Sherlock stayed next to the bed, looking down. He felt numb. He promised John he wouldn't let this happen to him. But Sherlock had fallen victim to his body and had dozed off... Ever since this killer came out and started hunting Muggle borns Sherlock vowed to keep watch over John. And for a while he did a good job of it. He stayed in the Gryffindor common room all night and stood watch. He refused to leave John's side unless he had too. And when he had too he made sure someone who wasn't a muggle born was with John.

When it happened Sherlock hadn't slept in over a week. He'd managed to get an hour or two in between classes when John was with his other friends (Sherlock was there too of course but he was asleep, or dozing). But this week not so much luck. John and Sherlock were studying in the library, and John somehow got him to put his head down for a bit and take a rest. His argument was that they were in a crowded Library, and that no one would attack him there.

"Sherlock, stop being an idiot and sleep a bit." John said with a small pout forming on his lips. Sherlock thought for a brief moment that John looked like a small child. It was cute. but he banished the thought from his head.

"No..." He said stifling a yawn. "Not tired." John glared at him.

"Come on Sherlock... One of these days you're going to fall over and pass out. Please sleep? Just a little nap. For me?" John said

"Fine. Wake me up in 10 minutes." Sherlock grumbled putting his head down.

"Promise. 10 minutes." John said with a smile. And then Sherlock fell asleep.

But he was not to be woken for almost 2 hours. John had simply let him sleep, knowing his friend needed it. John didn't notice as the Library slowly emptied aside form a bushy hair 2nd year whose nose was buried a book.

When Sherlock awoke it was to the noise of Madam Pence's scream of horror. There not 5 feet from Sherlock was John and a girl looking into a mirror in the girl's hand. Both of them were petrified. Needless to say Sherlock was, in a word; upset. John had been hurt on his watch. He had fallen asleep when he was protecting John.

So now here he was staring down at John's frozen face as he lay motionless in the hospital wing bed. Sherlock felt numb. This was his fault. he could have stopped this... So he'd find whoever did this and stop them. He gave John another look and deduced there was no trace of whatever did this to him. He turned his attention to the girl. She had a mirror in one hand and her other was balled into a tight fist. Sherlock felt around it and to his surprise there was a ball of crumpled paper. He pulled it out and unfolded it. He quickly read it over and smirked.

"Oh... She was clever. Very clever." He turned to John. "Cleverer than you anyway. So the monster's a Baskilus? Sounds like I need a parseltongue." And with that he promptly left the room.

So yep. Sherlock figured it out. So he went with Harry, Ron and Lockhart into the Chamber. As for what he did in the Chamber that's for another day. Hope you enjoyed that.
