Circuit

A nondescript gray van parked at the gates of the orphanage, but everyone in the area knew it was Kontur. The same ones that hunt for devilry and anomalies. Inside the building, it immediately became quiet; even the most unruly teenagers quieted down.
The services needed a child of about thirteen. Not to be rescued, and not to be placed in a foster family. Kontur had a very curious experiment in mind: they wanted to bring the teenager right to the epicenter of the devilry and see how the local anomaly would react to a living person. Simply to test the reaction, like throwing a pebble into water.
True, the operatives still hadn't decided who they needed. They stood in the middle of the hallway, arguing idly, leafing through personnel files:
— Let's take the girl. They're more emotional; the anomaly will react immediately to fear or panic.
— No, better than a boy. Thirteen-year-olds are more rash, they'll stick their noses in the wrong places, and their reactions will be cleaner.
While they were choosing between a boy and a girl, the teenagers themselves huddled fearfully in the corners. Everyone understood perfectly well: whoever the man in the Kontur uniform would ultimately point his finger at would be driven off in that van straight to the middle of nowhere. And no one knew if he'd ever come back...?
