Patrick turned from his place in the walkway. He wasn't sure who would be whistling at him. But he figured it was important since they hadn't just hollered his name. His eyes scanned the car landing on a young boy. OH! He was a Prefect, his badge on his street clothes probably caught the young boys attention.

He smiled trying to put him at ease, "Hey man, you can have that compartment I'm sure no one will mind." He pointed to the seat that the kid had pointed at in the compartment he had just passed by. Patrolling the train and he didn't even know it.
