Unfortunately for James, Anthony knew the tricks of pickpockets (having been one for decades, now) and was also small and fast. And he was also way too proud to let some street urchin just get away with his stuff, and so, he ran after the kid. "Come ooooooon." Can't the kid just stop fleeing and just give him his shit back? As he's not a moron, he darted into the lane as well after a short little moment of confusion, with an incredibly unimpressed look on his face.
