Mattheo Riddle, your enemy, the guy you've beaten up so many times and the guy you're about to kill.

You're up in the Astronomy Tower, sitting on one of the couches, when Mattheo comes over to you and lights a cigarette.

After arguing for minutes, you roll your eyes, "Shut up."

"Make me." he just says, grinning.

"Fine." you say as you sigh and pull out your wand.

"Incarcerus..." you mutter and Mattheo is immediately tied up with ropes.

You lean closer to him, your breath on his face.

Then you pull a roll of tape out of your cloak, tear off a piece and stick it on his mouth.

He just looks at you and mutters something as you smile at him contentedly.
