Just brewing up a little something...

Keith put on his biggest grin and stood up hurriedly. "Of course Mr Wake sir. Right away Mr Wake sir." As he stood, he very deliberately stuck his knee out and knocked the contents of the potion onto the ground. Looking up at the older boy, he put on a look of open defiance and spread his arms wide. "Oops."

Jack had begun to stand with Keith when he knocked over the potions. Jack gasped and fell to her knees as if to save the potions. "Oh, no!" She pointed her wand at the mess and muttered a Siphoning Spell as the potions began to disappear. "Drat!"

"I see." James tried his best to avoid an annoyed look. There were enough problems going about without Keith making illegal potions. "Then I assume you won't have any trouble explaining what potions you were making with the professor as well. In fact, why don't we talk down together. Along with your... friend," James narrowed his eyes on Keith's co-conspirator. It would merely take a drop to ascertain the potion. "Here, allow me to help," James said, levitating a glass vial quickly and swooping it over the mess, skimming the top and gathering just a mere drop of the potion. "Oops, sorry. Must've missed," he said, gripping the bottom of the vial so that they could not see how much he'd gathered. "Let me try again." This time, the vial collected a good portion of the spilled liquid. "Now, how about we show this to the Potions Master? NOW," he added threateningly.

Keith's eyes flickered between James, Jack, and the door very quickly.

What to do, what to do...

He could run, but James had his potion. So he needed to get that back...but the time to play innocent was drawing to a close. He was running out of options.

Thankfully he still had his most dangerous potion in his bag, safely out of James' line of site. He would still get in plenty of trouble from just the potion James had however. He could cut his losses, take the detention, and live to fight another day, but they might search his bag...which would not be good. He knew vaguely what he needed to do to get the same "drug-potion" as he had in his bag...so the safest thing to do would be to dispose of it now.

So, Keith curled his hands up into tiny fists, and hit James hard in the balls.

Jack's mind was reeling. She had joined the kid for some harmless trouble making, and now this other one was going to ruin all of it and get them in some kind of trouble. Jack was thinking hard, vaguely aware that they were going to have to probably resort to something a little more along the lines of violence.

Keith beat her to it.

Jack did not have time to register just how painful that was going to be for him. Instead, she leaped up and aimed very carefully at the little vial in the other boy's hands and said "Reducto!"

Keith was a lot of things. A liar, a trickster, a fiend. But moment all of James senses burst into pain, he added something quite unkind to that list. James, eyes watering, gripped Keith's arm as he caught his breath. The vial burst on his hands robe, but he barely registered it. He was going to drop the damn vial anyways. He was running out of patience, and he was probably about to do something very stupid. Something... no, James was not that person. He was patient, he had the maturity to... ignore... this offense. Inside his head, all the voices were laughing. But James failed to find the humor in his situation. His hand, gripped around the young man's wrist tightened as if to form a fist. His false hand, still holding what remained of the vial, formed its own fist, crushing the shards to a fine dust. He considered just punching Keith. Straight across the face, probably break more than just one bone. No, not an option. James had to suck up the pain.

What about breaking the boy's arm? No, no, PATIENCE. RELAX. BREATH. James had definitely suffered worse.
Dude, seriously, just castrate the mite! No, no, not an option. No purpose behind cursing the balls off a little boy.
Probably cause he wouldn't know what he'd be missing, Blue mused in between his snickers.
James whipped out his wand, and pointed it straight at the boy's face and, in calmest, most even voice he could muster, said "Petrificus Totalus."

The second that the other boy grabbed Keith, Jack froze for a second, knowing how stupid it would be to attack someone who was basically holding another person hostage. The boy seemed to be struggling with himself, rage and then cool indifference washing over his face at different times. It was quite strange and frightening.

And then he pointed the wand at Keith's face. Raising her wand, she heard him yell the spell and she yelled one not a second later, pointing right at the older boy. "Incarcerous!" Ropes shot out of her wand and headed straight for him.
