She was on edge. That could either work for or against him. He'd find out which here in a minute or so. As was his routine, he'd been as careful as he could be entering the station to keep his face pointed away from the cameras he knew to be burrowed into the walls around him and the girl. Not that Scout was always planning something sinister - it was just - he didn't want any more trouble than was necessary.
Tugging on his hood, the man smiled to himself as he heard the train approaching. It was still a bit away, but it was coming. He glanced backward over his shoulder to find the girl digging distractedly in her purse for something. He took another half-step back.
The nose of the train rushed by, kicking up all kinds of debris. Scout ignored it. Closing his eyes briefly, he imagined what he wanted to look like: a tall, thin man of indeterminate ethnicity, middle-aged, with large dark eyes and dark hair.
He felt his body restructure itself. To the girl behind him, it probably looked like he was shivering violently. Then, the man turned sharply on his heel and took one long step to reach the girl. A bony elbow came up to knock her hard in the face. Scout had the bag in his arms - she'd let go of it easily enough - and he rushed onto the waiting train. The doors closed behind him.
