Turn Back Time (Potterlock)

Tendrils of Magic

A/N This chapter has references to the ancient Greek Gods, and to the Percy Jackson world. If you haven't read Percy Jackson (and I suggest you do) all you need to know is the fact that Hecate is the goddess of magic (and my favourite goddess. She is awesome!)

Sherlock didn't change direction, and when I called he didn't seem to hear.
I let out a shout, and thrust my hand out.
Black mist swirled around my arm, and shot forward from my fingers.
I was only just controlling it, and managed to pull Sherlock back. He landed on the ground next to me.

"What was that for?" he asked.

"Running.. towards the... whomping willow.." I muttered.

"What's wrong?" Sherlock asked, noticing my tone.

"Magic... from my... mother." I muttered, curled up on the grass.

"I'm not that important. You used that power for me? You shouldn't have wasted it on me, a freak..." I tuned out, trying to stop the destruction that might follow the magic I had used.

I screamed again, interrupting Sherlock's insane babbling.

"Hetty?" he asked.

"I'm fine." I said, standing up suddenly, shocking even myself. He looked like he was confused for a moment, but I only glanced at Sherlock for a second. My eyes were drawn to my right arm.
The destructive power I could have unleashed was there, on my arm, in the shape of swirls and tendrils that looked like they were drawn onto my arm - even though I knew that it was magic on my arm, not ink, and would never come off. I knew that my power was safe, and I could use it without hurting people.

"Thanks, Hecate." I muttered. "Come on, Sherlock. I think we missed charms."

We walked up to the castle, and slipped inside. Sure enough, children were milling around, trying to get to their second lesson.

"Defence against the dark arts." Sherlock muttered to me.

"I can remember, you know." I replied.

We made our way to the Defence against the dark arts classroom.

Professor Lupin was there, but no one else was. Sherlock counted the desks, and found his seat. I slipped in next to him.

"You must be Henrietta." Lupin asked.
I nodded. He looked like he was going to say something else, but thought better of it.
There was something off about him, he was nice, and the lesson was fun, but he was obviously hiding something.

John walked with us to lunch. After his argument with Mary he seemed to have latched himself onto us, but it was good for Sherlock to have someone else to talk to.

Over lunch I explained to Sherlock how Hecate had harnessed my power.

"So, your mother made it possible for you to use both kinds of your magic?" Sherlock asked.

"Yep." I remembered something. "And even if she hadn't I would still be happy to use it to help you. You're not a freak, so don't call yourself one."

"Thanks, I guess." Sherlock picked at his food.

"You're welcome. Now eat something."

"Don't want to."

"Please..." I started.

"Sherlock, just eat something." Mycroft said from behind me.

"No." Sherlock replied.

"He doesn't want to!" I snapped at Mycroft. "Go away."

Mycroft didn't put forward an argument, surprisingly, and happily went to sit next to Lestrade.
