"Pull up your left sleeve." I said, putting down my textbook.

"Why would you want me to do that?" Mattheo asked.

"A normal person would just do it, what are you hiding?" I asked, trying to figure out something.

"Your brother told you to do this, didn't he?" Mattheo asked, pulling his left sleeve even lower this time.

"No, I just wanna know." I said, standing up.

"If you pull it up I'll put Stupefy on you." Mattheo growled. I ignored him because he was crazy but mostly because I had no idea what Stupefy was. I hurried and grabbed his sleeve and Mattheo tightly grabbed my wrist to move it away. Before he could squeeze my wrist even tighter I pulled up his sleeve and looked down at the mark his had on his forearm.

"What the hell is that?..." I asked.

Mattheo shook his head in fear and ran away to his dormitory.

"Could Draco have that too?" I mumbled.
