One particular day at hogwarts school of witchcraft and wizardry Fred and George Weasley found themselves in detention, again, for hexing their pens to write notes for them, again. While the twins sat in Filtch, the caretaker's, cramped office playing, Fuck, Mary, or Kill it was this particular day that they decided to snoop around in some easy to get into drawers. As the boys continued playing they grabbed all the stuff that Filtch had previously confiscated from them. Halfway through his statement George stopped speaking. His brother Fred looked over to him as noticed George holding a folded piece of parchment. The twins shared a devilish look and quickly snuck out of the office and back to their common room in the Gryffindor house. The two sat on the couch facing the fireplace as the common room echoed with silence.
"Reveal your secrets." Fred whispered excitedly pointing his wand at the paper. The parchment flooded to life in his brother George's hands.
"Messrs Moony, Wormtail, Padfoot, and Prongs, would like to offer their help to Fred Weasley and offer that he keep his large freckled face out of other people business!" George chuckled out. Fred slapped his twin upside the head before both continued to laugh.
"There has to be more to this!" They said in unison looking at the now fading paper.
"Open says me!" Fred tried.
Nothing.
"Alohamora!" George tried his wand now on the paper too.
Nothing.
"Behave!" Fred said.
Nothing.
"No good." Whispered George looking at his brother solemnly. The paper sparked a bit but neither boy noticed.
"It's gotta start with something." Fred murmured. "Like I promise, or I swear." He continued. George dropped his eyes back to the parchment while his brother rambled on. At one point while Fred was talking George thought he saw the paper spark. George thought nothing of it and let his brother ramble.
"Well I mean it's gotta have a start but then something to continue it, like 'be bad', y'know?" George interjected his brother. Fred nodded and looked at the paper again.
"I promise I'm gunna be bad!" Fred tried.
Nothing.
"I promise to be dangerous!" George said.
Nothing.
"I promise to kill everyone!" Fred said sinisterly. George gave his brother a strange look, Fred shrugged.
"Maybe we need to try something worse...." The duo pondered at the same time.
