You and your enemy, zeno were in detention at the moment.

You both sat a few seats away from each other. Suddenly another kid from one of your classes came into the room.

He glanced over at you and sat next to you. For a slight moment you saw zeno's jaw twitch, like he was angry?

The teacher leaves for the toilet and the boy shakes your hand as he starts a conversation.

All of a sudden zeno got up and dragged the boy out of the class by the collar --next day-- You were in class the next morning with zeno as he teased you, like always.

Suddenly the same boy from yesterday came in.

And that's when you realised he had a cast on his right hand, the same hand he had shook your hand with...

You instinctively look at zeno but he was instead, smirking.
