Pietro wasn't used to trains. He was used to traveling by other methods. Like muggle cars. Or broom. Or even floo and portkey! He had never been on a train before so his legs felt strange as he was walking to find a compartment. He nearly fell over his own feet when he slid a random compartment door open. The compartment was already occupied by a person curled up in the fetal position. Pie found this very strange but he wouldn't be a bother to him. This kid looked real sick, though. He tapped the kid on the shoulder and gave him a puzzled look. "Aye. You okay?"
