CHAPTER 4: CHEATER

As soon as I was finished my math class, I stepped out into the hallway.

At that exact moment I saw Sebastian and some other girl talking.

Don't get me wrong, I wasn't the jealous or possessive type of girlfriend, so as soon as I saw the two of them chatting, I just walked on up to my locker.

I stacked my books up and grabbed my lunch, and slammed my locker shut.

Only to see the girl walking towards the private toilet and Sebastian following her in.

That bastard!

I walked up towards the toilet door, which had a sign saying PRIVATE TOILET, with a sign of a man and another with a woman.

It was for kids that liked to go to a toilet alone. There were five others in the school.

I put my ear to the door and heard a moan.

I felt like crying, but I quietly opened the door, to find Sebastian and some blonde bimbo with her tongue down his throat.

"Enjoying that?" I asked, putting an emotionless expression on my face.

They sprang apart.

"It's not what it looks like, Clary!" Sebastian said, his eyes wide and shocked.

I scoffed in disgust. "Really! That's what every fucking jerk says when he's caught! So I don't buy it! It's over!" I snapped.

I spun on my heel, fighting the tears away.

I walked towards my locker and leant my head against it.

There was no one else in the hallway, so I had the time to myself.

I felt betrayed, and heartbroken.

Anger surged up through me, and I wanted to go back to New York and kill a couple demons.

"Clary?" A voice called.

My head whipped to right, where the voice had come from.

It was Jace.

"What?" I snapped.

"Well someone's in a bad mood. Isabelle told me that if you don't hurry up and get in line with her, she's to grab the last ham and pesto wrap on you and eat it herself," he said.

I scowled.

Ham and cheese pesto wrap was my favourite food to get, along with my lunch mom made for me.

"Tell her I'll be there in five minutes, " I told him.

He nodded, but his golden eyes scanned my face.

"Are you alright?" He asked.

"I'm fine. Just go!" I said tiredly.

He turned and left.

I stood aagainst my locker for two more minutes, fighting back the tears.

I'll cry later, right now, I needed to go to Izzy before she has a fit.

As I walked into the cafeteria, I caught sight of Izzy waiting in line.

I walked towards the line, and she waved me over.

I came over and we ordered our food.

We sat down at a table with Alec, Jace, Aline and Helen.

Normally we would of had Sebastian at the table, but he wasn't here.

"Clary, something's wrong. I can feel it in our parabatai connection," Izzy murmered to me.

I pulled my lips into a smile. "I'm fine Isabelle. No need to worry about me," I lied.

She narrowed her eyes at me, but went back to her conversation with Aline and Helen.

"Where's Sebastian?" Jonathan asked loudly.

I resisted the urge to flinch.

"He had to stay behind and do his not done homework, " I lied again.

Normally I would never lie, but I didn't want to discuss with any of my friends about what happened.

"That typical Sebastian, " Alec said rolling his eyes.

Jonathan laughed.

I didn't.

Later that day, I went straight to my room and cried and cried for a half hour.

After that, Valentine called me down for training.

I was practicing with Isabelle today. We were doing weapon fighting, using a deadly steel ellectrum fan that could chand into a sword if you closed it.

It was green, with the angelic rune engraved in it.

My favourite weapon besides the seraph blade and steel ellectrum fan, was the katana.

I put all of my anger and betrayal into the fight with isabelle.

I won in the end.

After we healed each other with iratzes, we went up to my room.

"All right, what happened?" Izzy asked.

I sighed.

She needs to know. She's my parabatai for the Angel's sake!

"Sebastian cheated on me," I told her.

"That fucking lying, cheating, BASTARD!" Izzy yelled.

My eyes went wide at that last word.

Even though it was all true, if Valentine heard her, I'd be in big trouble.

Swearing was not tolerated in the manor.

"Izzy, please don't do anything to him, and don't tell anyone . I'm not ready to tell the others," I told her.

"Okay," she said.

I relaxed.

We talked for a while, and then she went home to the Lightwood manor.

After much thinking about what Sebastian had done, I'd made up my mind.

I'm not going to fall in love.

Ever.

So what do you think?

Please give me ideas. I'm not going to make Clace immediately though, but I need ideas before I run out.
