Keith figured it was safe to say he was enjoying himself. The music was loud, the alcohol was flowing freely, and nobody noticed a little squirt like him. Unlike some people, Keith enjoyed feeling invisible. It gave him a sense of empowerment, to know that come tomorrow not many people would even remember he was here, let alone what he did.
Anyway, he was enjoying himself. He stepped outside for a breath of fresh air and noticed a few older students in the woods not far away from the back door. Curious, he approached them, and noticed that there were three of them.
Two boys and a girl. One of the boys had his arm around the girl, and they were obviously both drunk, talking in low tones with the other boy, who appeared sober. Keith saw a brief flash of galleons, and the boy and the girl stumbled drunkenly back towards the house.
Keith frowned and ducked behind a tree, straining his ears to overhear their conversation.
"No I swear, this shit is the best," the boy said. "It's usually a lot more expensive though."
"Doesn't it make your eyes look pretty?" The girl asked.
"Oh yeah, like this really deep blue. It's pretty awesome. You really have to try it," the boy said. Keith's face changed to an expression of shock, and he stepped out from behind the tree, blocking the two's path. Over their shoulder he could see the other boy taking a piss into the woods - he was too far away to hear if they talked quietly.
"What the hell is this?" Keith said in a low tone, walking up to them. He was presented with Taylor Hawson, a short, overweight 5th year Hufflepuff, and a plain looking brunette he didn't recognize. "Taylor?"
Taylor stopped suddenly, hand shooting into his pocket. "Keith. Aren't you a little young to be here?"
"Shut the hell up Hawson," Keith said. he stepped forward, and Taylor tried to shove him away - but the boy was so drunk he missed completely. Keith's hand darted into the boy's coat pocket, and came out a moment later with a vial of silvery-blue liquid.
Keith unstopped the vial and took a sniff. It was Spice alright. But wrong, like someone had forgotten half of the ingredients.
"Cheap B****," Keith said, throwing the vial onto the ground. It shattered, and Taylor tried to protest, but Keith stepped on one of his toes and pushed backwards. Taylor tumbled to the ground, and Keith shot the girl a mean look. She scampered without a word.
The other boy was still peeing (Keith vaguely remembered early versions of Spice giving you bladder problems) so Keith stalked silently towards him, bending down and picking up a heavy branch.
Then, with one smooth movement, Keith slammed the branch into the back of the boy's knees.
