Things not to do at Hogwarts
If a classmate falls asleep in class, I will not take advantage of the fact and draw a dark mark on their arm.
It was History of Magic and Harry Potter was bored. He was so bored he'd even read the chapter Binns' was droning on about in his textbook. That was when he noticed Ron was sleeping with his arm right in front of him and an evil smile spread across his face. "Time for some Payback!" He thought. Hermione saw the look and gave him a glare "Don't you dare do anything!" She whispered harshly to him.
However, Harry was already drawing on Ron's arm. The Slytherin's in the room were looking over at them, wondering what Harry was doing.
When Harry stepped back from Ron's arm, there was an almost perfect replica of the dark mark on his arm.
"Potter, how did you do that?" Draco Malfoy asked
"I drew with a marker, duh." Was the reply
"But how did you get it that accurate?" Pansy Parkinson asked
"You'd probably be surprised and concerned about what goes through Voldemort's head." Harry told her "in fact, if most of his followers knew what he thought about he would probably lose them all..."
"Harry! You shouldn't encourage that link! You know what Dumbledore thinks!" Hermione chastised.
At that moment Ron woke up.
"What the bloody hell are you two arguing about?" At that moment he saw the mark on his arm and fell off his chair. "What! How!" He sputtered
"Welcome to our ranks, Weasley. Tell me, what are your current orders?" Malfoy said
Ron could only stare dumbly at his arm and back to Malfoy again before he fainted.
"To be honest I didn't think he'd last that long." Draco drawled "you should probably get rid of it before he wakes. You wouldn't want him fainting again."
With a quick spell, Ron's arm was back to normal.
After class Draco cornered Harry and there was an exchange of Galleons before the separate parties parted ways.
