Even though he was able to figure out what the stuff is, Radon wasn't pleased by the results. Magical drugs meant bad news. He'd have to call the authorities on this one. Luckily his work as an informant sometimes helped him stay on the good side of the law. Radon was about to make the call when he realized he hadn't checked his sensor's recording. He smacked the back of his head as a wake-up call, then proceeded to access his sensor.
The sensor has a very clear image of the girl. She wanders around the room a couple times, looks at some magazines, and flops into a chair with a very bored expression on her face. Then she gets a shifty look, glances around surreptitiously, and pulls the matte black vial out of her pocket. She stands up and moves directly under the light fixture, squeezing the vial tightly in her hand and holding it toward the light. After a long moment, she opens her hand and the vial is clear; in a half second the vial starts glowing, and she quickly pulls the stopper and downs the liquid inside. Then she sits again and closes her eyes, her face becoming blankly blissful.
A few minutes pass, and then she begins to convulse, her limbs flailing. She knocks over the magazine stand and falls to the ground.
Lilly begins to drag the kid down the road, towards the nearest medical centre. "Hopefully we can leave him here and both of us can be on our respective ways."
Lilly and IA carry the boy towards a medical center Lilly remembers from her wandering. As they go, the kid mumbles unintelligibly under his breath, almost without stopping, and without moving.
After 5 minutes of walking, the kid convulses again, wrenching himself from the girls' grip, and falls to the ground. Before they can react, he slowly stands. His eyes are open and completely black... he holds his hands out, looking at his palms, as they begin to glow with a blinding light.
"...boom..." he whispers, then turns toward the girls.
